WRT54G3G-ST router - no internet connection - can't reset router

Hello. Definite longer story definitely not short (I apologize for the rambling length... I don't know what is and isn't important, so scan at will, please... I am sorry...): Recently my computer (Dell XPS 400, Windows XP Service Pack 3, Internet Explorer 7 with phishing filter and pop-up blocker on, SiteAdvisor, up-to-date McAfee Virus Scanner and Firewall, and a Linksys Wireless-G WRT54G3G-ST router with its power adapter plugged into the wall electrical outlet and a network cable from it directly connected to my computer.) got a drive-by Generic.dx trojan without me downloading anything from one of the few sites I visit daily. My internet connection crawled, and I now have no connection at all.
I've been getting help from McAfee forums very helpful and quick good volunteers... They recommended Malwarebytes Anti-Malware to me, which I downloaded from my second clean computer (a laptop) to my flash drive, then to my infected computer. I ran it, tried updating it as recommended, and only then discovered the trojan killed my broadband entirely. I scanned with it anyway, and it quickly found and removed/quarantined 11 Adware.MyWebSearch related files, but nothing else. They then gave me a link to an offline updater patch file, and told me scan in safe mode until nothing else was found and check if it fixed my lack of broadband access. Which I did, Malwarebytes found nothing else, but unfortunately I still had no broadband.
Next, they recommended WinsockXPFix. Which I ran and it made all its registry changes OK, I rebooted as required but still no broadband unfortunately. Did using WinsockXPFix make things worse for me with the registry changes it made? I used its registry backup to save the pre-changed registry files prior to running. Should I revert back since I still have no broadband connection? The McAfee volunteers then kindly told me I needed to hard reset the router, though I've tried countless times with no fortune. I'm at a definite loss as to what, if anything, I can do to hopefully get my broadband back, please...
It's very confusing with the numerous different variations to reset routers, and what I need to do for my router model (Variations: Unplug this cable/adapter exactly where, or not; hold the reset button between 5-30 seconds; rebooting the computer, or not; waiting 1 or 2 minutes between various steps, or not - and for all of these at what exact point in the reset process.).
I reset it once before with the reset button, routers page at http://192.168.1.1, default admin password, then changed it for security, etc; but this time I can't get it to work. I'm happy as can be to try again, to get a walk-through maybe, anything please... When I go to http://192.168.1.1 now, or any other address, Internet Explorer gripes at me that I'm offline, which is annoyingly correct. I don't have, and never had Zone Alarm, but disabling my McAfee Firewall doesn't help. IPCONFIG at the Command Prompt gives me a Windows assigned address of 169.254.X.X
I was going to use the routers Setup Wizard CD to try to reset the router, and if that failed to try to get its firmware version number to maybe upgrade. But I was going to ask here first for expert advice since I've read many things that can go wrong while upgrading firmware. However, scanning the CD (Without running the CD.) McAfee found the virus W32/HLLP.Philis.ini in the file "D:\_desktop.ini" on the CD. McAfee didn't delete the file, I don't know why.
   I scanned my entire computer several times and no infections were reported. I uploaded the file several times to both www.virustotal.com (39 online virus scanners), and virusscan.jotti.org (20 online virus scanners) and every time every virus scanner reported no possible infections. Is my up-to-date McAfee virus scanner reporting a false positive and yet Jotti and Virustotal's 2 McAfee scanners report the file as probable clean? Is "_desktop.ini" a legitimate Linksys file? I found no information on Linksys/its forums about it. My problems just keep multiplying...mentioning of more problems...
Finding that suspect file on the CD I decided to instead download the Setup Wizard from Linksys
(Router product page: http://www.linksysbycisco.com/US/en/support/WRT54G3G-ST/download
Actual file: http://downloads.linksysbycisco.com/downloads/WRT54G3G-ST_SetupWizard_4_2_06042008.zip)
to my flash drive, then to my infected computer that is connected to the router. I ran it (Downloaded file version: 4.2.0.007 - Original CD Setup Wizard version: 4.0 printed on CD front.) and it immediately gave 1 of 3 options: Mobile Broadband Only, Broadband WAN Only, or Broadband WAN and Mobile Broadband. I don't know what damage, if any, I caused by continuing.
   It looked like it was trying to go through the entire router setup process. I thought it would take me to some options to reset the router, as I've read in the User Guide and elsewhere - that was my understanding. The setup process stopped at only 30% done "Router not found, please make sure the router is properly connected and try again." How much overwriting of original router setup files did I do by continuing? I'm entirely confused. Doesn't the Wizard check if the router has been previously setup prior to setting it up again? Did the version difference cause my router to not be detected by the Setup Wizard? Did the Generic.dx trojan that killed my broadband trash my computer settings so bad that my router is undetectable/essentially not setup?
Update of sorts: I tried one last time to reset the router, and I unplugged/plugged the network cable. Doing that I still had no broadband on my main usage Dell XPS computer that's connected to the Linksys router. However, my laptop, with Data Card in the router, was for the first time able to find the network - the constant connection and speed is brilliant, it's what it allways has been on the laptop (Since the trojan/router problems, my laptop only had broadband with the Data Card in the laptop.). Maybe the network cable simply wasn't re-connected properly/entirely during 1 of the many reset attempts, it indeed could also explain the downloaded Setup Wizard not being able to find the router/only getting 30% done.
Laptop Command Prompt IPCONFIG /ALL with Sprint Data Card inserted in laptop computer slot:
IP Address    = 174.158.XX.XXX (Sprint)
Subnet Mask = 255.255.255.255
DNS Servers = 68.28.90.91
                         68.28.82.91
Laptop Command Prompt IPCONFIG /ALL with Sprint Data Card inserted in router:
IP Address    = 192.168.1.1XX
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.1
DHCP Server      = 192.168.1.1
DNS Servers      = 192.168.1.1
Since my laptop started working with the Data Card in the router I haven't tried again to reset the router, nor have I tried the downloaded Setup Wizard. I don't want to mess anything up further than I have(?) / the trojan has, and I need some expert advice, please, as to which of the 2 if either I should do (first?). On my laptop computer only, typing http://192.168.1.1 in Internet Explorer gets the pop-up for username and password, but I haven't proceeded. I've read you shouldn't reset the router and/or(? Is it both or just 1 please?) upgrade the firmware unless the computer is directly connected to the router - which my laptop is not. On my other computer that still has no broadband, Internet Explorer still tells me I'm offline when typing http://192.168.1.1 into it. My IP Address on it is still a Windows assigned 169.254.X.X and a Command Prompt PING 192.168.1.1 returns with "Destination host unreachable.", as it allways has and same with all other addresses (Except for 169.254.X.X).
Annoying 2nd "update" of sorts, apologies for length, as allways: I've been so focused on the trojan/broadband killing that I've cluelessly largely forgot that I have dial-up with AOL. Trying AOL dial-up also does not work, the insanity thickens... AOL software tells me to check my connection, but all phone cords are plugged in as should be. I plugged a phone directly into the wall outlet and I get a dial tone, I can call out OK, and the phone rings and gets calls OK. Device Manager-Modems-Properties-Device Status says the modem is working properly, and Resources Tab shows no conflicts. Diagnostics Tab's Query Modem looks OK to me, as does the log, but as allways I'm definitely no expert. I didn't change any settings anywhere.
   I have noticed off and on that checking IPCONFIG it says my IP Address is 192.168.1.100   It lasts maybe a day (then goes back to 169.254.X.X), maybe longer, I don't know - I don't check that often to pin it down (Should I?). During this time neither my broadband, nor my dial-up works. I can PING 192.168.1.100, but nothing else. I'm convinced the evil trojan killed both my broadband and dial-up - I've never had a problem with my Conexant D850 56K V.9x DFVc Modem prior. Also, I'm not convinced the trojan is not still lurking everywhere on my computer, I think it is...
Any and all help in restoring my broadband/dial-up is greatly appreciated, please... Thank you!
Solved!

Hello. It's been entirely too long since I've replied, I'm sorry. There's no excuse, and it's terribly rude of me... You took the time to read and reply to me, and I endlessly appreciate that indeed. I apologize for my long delay, I'm sorry...
After I left my message I downloaded many virus/spyware scanners, etc. from my laptop onto my flash drive, then my other computer for some needed thorough deep scans. One that I downloaded was Network Magic, which somehow, someway fixed both my broadband/dial-up internet on my main computer that's connected to the WRT54G3G-ST router. I don't know what/how it repaired my connection, but the broadband connection/speed has been working brilliantly since... Network Magic worked for me, and I highly recommend it to everyone who has stubborn complete lack of internet problems (caused by trojans at that) as I did. There's no guarantee it'll work, but it did for me to my amazement.
Network Magic, as is Linksys, is owned by parent company Cisco. Respectfully to all the good knowledgeable experts here (Which clearly I am not.), I don't want to tread out of my bounds. I'm simply trying hopefully to be helpful and save some headaches for both you the volunteers and the users...buying a new router and/or computer was on my mind, with all due respect I recommend suggesting to try Network Magic to users if resetting the router/all else fails, please. I did use WinsockXPFix/WinsockFix utility prior to using Network Magic, I don't know if that matters.
I also upgraded my McAfee package, I installed over my old software instead of uninstalling first, which caused errors in the virus scanner of all critically needed things. I have it installed properly now, but it did cause quite a delay in re-focus of my time. Some of the virus scans also found many trojans, some were the same/in the same folders that killed my broadband - which stopped me in my tracks to insure uninfected cleaning.
That definitely doesn't entirely explain the long lapse of time, and I apologize for that, again. It's just that I'm trying to be cautious and slow in all this. To answer the first very good idea you made: Unfortunately, there's no place on my other computer to plug the router in to, which all the more so caused frustration (at the time). I forgot to include this in my novel length post of countless things to check/remember... It was a brilliant idea though, thank you...
I thank you for your time and help, I do sincerely appreciate it... Thank you... I think, and hope this matter is solved. It seems to be, the router is working perfectly as it allways has, and I'm positively happy as can be about it. Thank you... Peace...

My WRT54G v5 router loses internet connection frequently

My WRT54G v5 router loses internet connection frequently. Sometimes occurs when you enter a web or sometimes every few minutes, but without a pattern. I have W XP Pro with SP3 and I have a pc wired to the router and sometimes 2 notebook with Wi-Fi. What could be the problem?. Thank you very much.

I have upgraded the firmware to v 1.02.8 and reduced the MTU to 1350 but after a few minutes of doing that I had the same problem... The router reboots itself, again and again and again...
It's possible to run some diagnostic utility that somebody can check ??
It's possible it would be a router failure ??
I note that sometimes is ok and when Entering some web pages the router reboots itself and I loose my internet connection, but others, the router reboots for no apparent reason...
I dont know what to do...

Internet connection lost with EA6500 router

I'm using a fiber optic internet connection and a Linksys/Cisco EA6500 router, with unlimited internet plan. Usually (1 to 2 days), the internet connection is lost and the way to get it back is the radical way in IT: 1st: switch off the modem and the router and wait a couple of minutes; 2nd : switch on the modem and the router. I suspect that this very annoying problem is related to the router settings. Someone can help me in get over this problem?
Thanks in advance.
Nuno

With this type of scenario, this will show that a reset on the router is needed to stabilize the router’s performance. One isolation step that you can try is to connect the computer straight to the modem. In that way, you will be able to determine if the connection coming from the modem is stable. Another step that you can try is to adjust the router’s mtu size by using this link: http://kb.linksys.com/Linksys/ukp.aspx?vw=1&docid=efe3edfeced9436a9f13eeebc89f90c2_4031.xml&pid=80&r.... By doing so, the router’s intermittent internet connection problem can be resolved. If in case that those steps will not improve the router’s internet connectivity, then you can consider returning and have that router replaced.

On iOS 6.0 how can I Airplay to AppleTV using router without internet connection.

Hello,
I do a lot of presentations. I recently updated my iPad to iOS 6.0. In the past on iOS 5 I used an iPad, AppleTV, router, and projector for presentations. Now when I connect the iOS iPad to the router it requires the router to be connected to the internet so the iPad can connect. Iam often presenting at places that do not have internet so this is an issue. Is there anyway around this? I have done some testing and it appears that the iPad has to authennticate to Apple everytime it wants to connect to the internet.

You cannot use your iPhone as a router without being connected to data.
That is essentially what I said above. When streaming local content you won't incur any data but you can't use the feature while in airplane mode.
However; you can use an airport express (2nd generation) as a router without being conected to the internet.
Yes, An Airport Express is a router, which is what I recommended initially as it is a much better solution, glad it's all worked out.

My time capsule runs very slowly and keeps disconnecting my internet connection, can anyone help me please?

Hello all I have recently pulled out my 3TB Time capsule and attempted to use it to back up my all Mac network, starting with just my desktop. I gave up on it before and started using Time Machine with WD EHD's which work fine. The reason that I gave up was that the Time Capsule kept freezing and hanging and I couldn't rely on it for a back up. I have reset it to factory settings and reconnected it as per the instructions, using it to extend my network, the hub is a BT infinity setup. Anyway it looks like it is going to run, then keeps shutting down my internet connection and I suspect it is taking longer to run the backup than it should. Has anyone else had this problem or can help please?

What model is the 3TB TC??
If the computer is using Yosemite the setup of the TC needs to be right. It can also be hardware issue if you are talking about the previous gen4.
Here is a list of things that can help with yosemite.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 for basestation and and TCwifi wireless name.
If the issue is wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. ie plan on a first and second round of changes to fix this.. hopefully.. I will point out other steps that can be round2.
2. Use all passwords that also comply with 1. but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. If the TC is main router you can skip this point. This is only an issue when the TC is bridged.
Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only. Do the same for ethernet if you use it.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the computer itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.
Macbook can't find Time Capsule anymore
Start from the bottom and work up.. I have a list of good network practice changes but I have avoided Yosemites bug heaven.
Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.

Correct IP address from router, no internet connection

I setup a network with four PCs. Three of the PCs are connected directly to the router, and one is connected wirelessly. The three PCs wired in are working just fine, but the wireless one is not. When I first set up the connection, I had an internet connection, and suddenly it stopped, and I have not been able to get it back.
I disconnected and reconnected the wireless connnection, and I couldnt get an IP address. I disabled the firewall, and then I was able to get an address (192.168.1.112), but no internet connection (limited or no connectivity). In testing the connection, I was able to ping to the IP successfully, but in pinging from the bad PC, i was not able to get a response. So i think the adapter is sending signals, but not receiving them from the router, hence no internet.
Is there something simple that I am overlooking? Any ideas??

Sorry, this isn't the answer, but I have the same problem, but with a Mac.
We have an old Sony Vaio, an older Mac Powerbook G4 17", and a new MacBook 15". The Viao and Macbook have no problems but my 17" can only connect to the internet hardwired. Wireless, I can only get to the router, but not past it? What gives?
We have the WRT54GL (fw: 4.30.0), which replaced our old (wireless) BEFSR41 which had an Airport hooked up for wireless. That setup worked great. My 17" is running OS 10.4.7 and has the lastest firmwares.

Cisco 3725 Router for Internet Connectivity

Hi,
We have en existing Internet connection using our Cisco 3725 router (ISP A). The router does the NAT and here's the existing default route:
S* 0.0.0.0/0 [1/0] via 1.2.3.153
This router has a "16 Port 10BaseT/100BaseTX EtherSwitch".
Now we have a new Internet connection (ISP B). What I did was to configure two ports on the Etherswitch and added route maps:
interface FastEthernet1/0
description "ISP B to provider"
no switchport
ip address 4.5.6.66 255.255.255.252
interface FastEthernet1/1
description "ISP B to my network"
no switchport
ip address 4.5.7.225 255.255.255.248
ip policy route-map ISPBInternetTraffic
access-list 101 permit ip 4.5.7.224 0.0.0.7 any
route-map ISPBInternetTraffic permit 101
match ip address 101
set interface FastEthernet1/0
set ip default next-hop 4.5.6.65
What I want to happen is that when the router sees the traffic coming from the public IPs of ISP B (4.5.7.224 /29) it will direct that to go out ISP B on F1/0.
1. Is my configuration correct?
2. Any suggestions, recommendations?
3. Can I do load balancing or load sharing between the two ISPs?
Best,
Tony

Hi Tony,
Your question has already been answered here: http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Network%20Infrastructure&topic=WAN%2C%20Routing%20and%20Switching&topicID=.ee71a06&fromOutline=&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.2cd276a5

Internet Connection Sharing and NFS route problem?

My new box is yet to gets its wireless card so following the wiki I have painlessly set up ICS - this works great. The ICS host connects to my wireless router on wlan0 and to the ICS client on eth0. The ICS client attaches on eth0.
From the ICS client I can ping eth0 and wlan0 on the host and also the router but I can't access the NFS shares on the host - should I be able to access them on both wlan0 and eth0 - even if I bring down wlan0? I'm guessing I need another iptables rule...

I'm not quite sure I understand whats happening here.... So here is a "diagram":
ICS cli --- eth0 ---> ICS host --- wlan0 ---> router ---> internet
Yeah? From this, there is no reason for wlan0 to affect NFS from cli to host, assuming everything has been set up properly with the routing tables.
If you disable all iptables stuff (which is how I'm assuming you have the routing working), does NFS work? Have you set up your /etc/exports properly?
Can I see your iptables stuff as well?
And on a side note: I recently chucked NFS in favour of sshfs, it's much better for me personally. Considered that?

Internet connect and net 75 route installed

running 10.4.10 I am connecting to the internet via the internet connect software. After I connet I get a default route but also a net 75.0.0.0 route with the ppp0 gateway gets install. I am trying to figure out what is responsible for installing the route. The console logs do not show any log entries that
I have to manually remove this route when I disconnect so until then anything destined for net 75 is blackholed.
Any clues how I can figure out what is responsible for installing the route and perhaps, how I can stop the route from being install.
Internet:
Destination Gateway Flags Refs Use Netif Expire

66.174.30.4 75.208.81.118 UGHS 0 0 en2

192.168.0 link#9 UC 0 0 vmnet1
192.168.149 link#8 UC 0 0 vmnet8

Since the route is for the entire 75/8 subnet and it's assigned to link#10 that implies that your machine has an interface in the 75/8 network.
Since 75/10 is assigned to SBCIS (now AT&T) and 75.64/13 is Comcast (who used to be run by AT&T), it seems clear that AT&T and/or Comcast is your ISP.
It's very common for cable companies to use very large subnets for their network.
At the end of the day, though, this indicates perfectly normal behavior and you are going to run into problems if you try to blackhole that network since it is required to talk to the upstream AT&T/Comcast routers.
If you're worried about sitting in the middle of such a big subnet (along with all your neighbors, etc.), well... that's what NAT routers are for.

Hard wired PC losing internet connection with WRT160N V2 Router

I'm new to routers and I just added a WRT160N (V2) router. The wireless connection through my laptop is great. However, I have 1 PC physically connected to the router. The internet connection is sporadic on this PC. I have high speed "wireless" internet service and sometimes you click on the internet or check e-mail and there is no internet connection. It seems to be after the PC has sat idle for a while. When you click the internet, the PC icon on the router does not even blink - its like the PC and router are not talking. If it does connect, the connection is great. Any help would be appreciated!
Solved!
Go to Solution.

There is a known issue with intermittent connectivity and the Build 11 firmware for the WRT160N V2. Build 11 is the current firmware on the Linksys site. Check to see if you have Build 11 if your router is a V2.
Downgrading to Build 8 is generally accepted to correct these issues, however Linksys have indicated to several people they do not have the build 8 firmware to give to end users.
This is ONLY for WRT160N V2 routers. This firware will not work on WRT160N V1.
You can find it at http://audipages.com/router/
Follow the dowload and firmware downgrade instructions on that page.

Internet connection via Airport Extreme/router thats not working, why?

I have been having problems with the internet connection via Airport Extreme which I find it a bit unusual and its still driving me nuts! This is what happened:
I have lost my internet connection last Sunday evening upon my return from a weekend away from home. The last time I have used the internet connection on my macbook was the previous Friday morning. Prior to the apparent disconnection on Sunday, I have always used my internet connection wirelessly through Airport Extreme (that is connected via ethernet cable to the NETGEAR DG834v2 ADSL modem which had worked beautifully until the problem arose on my return). This wireless internet connection allowed me to surf the internet anywhere in my home.
However, upon the successful re-connection to the internet via the modem router, I have discovered several new problems. I have tried to set up the internet connection wirelessly again but instead the following happened:
1. Router (Netgear) drops ADSL connection and cannot reconnect when connected to airport via Ethernet. (which is the case when using airport wireless).
2. Router connects to ADSL fine when computer is connected to it via Ethernet. (However, router disconnects when magsafe power adapter is taken out for some inexplicable reason!)
3. Router connects to ADSL fine when nothing is connected to the router (ie. No Ethernet connections)
4. Router connects to ADSL fine when connected to airport via Ethernet and computer is connected to airport via Ethernet.
So from the above, I cannot connect to the internet properly whether wirelessly or not so I suspect it could be faulty router or could it be airport extreme? I have asked my ISP for an explanation and all they have said is that it cannot be the mis-configuration but could be to do with the power adaptors or the way plugs are set up and suggested I take out all the power plugs (and power surge protector) out to switch everything off, the macbook, router, printer and airport extreme. However, when I have re-plugged them all back in, the problems I have described above still persists!
Would appreciate any help if anyone here recognises why this is the case and what seems to be the cause of this. If so, what should I do? Though I have written back to my ISP again yesterday for more help so im waiting to hear from them...
Thanks

Prior to the apparent disconnection on Sunday, I have always used my internet connection wirelessly through Airport Extreme (that is connected via ethernet cable to the NETGEAR DG834v2 ADSL modem which had worked beautifully until the problem arose on my return). This wireless internet connection allowed me to surf the internet anywhere in my home.
However, upon the successful re-connection to the internet via the modem router, I have discovered several new problems. I have tried to set up the internet connection wirelessly again but instead the following happened:
1. Router (Netgear) drops ADSL connection and cannot reconnect when connected to airport via Ethernet. (which is the case when using airport wireless).
2. Router connects to ADSL fine when computer is connected to it via Ethernet. (However, router disconnects when magsafe power adapter is taken out for some inexplicable reason!)
3. Router connects to ADSL fine when nothing is connected to the router (ie. No Ethernet connections)
4. Router connects to ADSL fine when connected to airport via Ethernet and computer is connected to airport via Ethernet.
So from the above, I cannot connect to the internet properly whether wirelessly or not so I suspect it could be faulty router or could it be airport extreme? I have asked my ISP for an explanation and all they have said is that it cannot be the mis-configuration but could be to do with the power adaptors or the way plugs are set up and suggested I take out all the power plugs (and power surge protector) out to switch everything off, the macbook, router, printer and airport extreme. However, when I have re-plugged them all back in, the problems I have described above still persists!
Would appreciate any help if anyone here recognises why this is the case and what seems to be the cause of this. If so, what should I do? Though I have written back to my ISP again yesterday for more help so im waiting to hear from them...
Thanks

WRTU54G-TM router loses internet connection and needs to be restarted to regain connection.

We recently switched from a WRT54G to a WRTU54G-TM router from T-mobile and the new router seems to randomly lose our internet connection and needs to be restarted to regain it. It could be coincidence but this has happened a couple of times immediately after using our VoIP phone connected to it. I tried switching back to the old router and everything worked fine once again. Typically with the WRTU54G-TM it will stay connected for about a day or so and then it will need to be restarted. Although sometimes it will need to be restarted multiple times in one day. Just curious if anyone had any quick suggestions or setting configurations that I may have missed?
Thanks for your input.

I just added the T-Mobile@Home service and set up a WRTU54G-TM this past Saturday. During the first 4 days, the blue light on the router went out and I lost phone service - until rebooting the router each time. Phone service returned about a minute after rebooting in each case.
I did NOT lose Internet service while phone service was down.
I reached T-Mobile customer care the second time, and the rep I spoke with mentioned that she had a couple of other calls similar to mine earlier in the day. So far, the reps had no official word regarding this problem, and the word going around was simply to tell people to reboot their routers.
Tech Support had about a 20 minute hold queue, so I didn't yet to speak with a technician.
The phone service has been up for the past 2 days -- curious to see how long it holds up this time. Also checking the Linksys site regularly to see if new firmware (beyond the 1.00.04 I have loaded) becomes available - maybe that will address the problem.
When I complained to customer care, the one thing they did was to extend my "buyer's remorse period" to 30 days (instead of the usual 14). So I plan to hang on for another couple of weeks to see if this gets straightened out. I love the service, sound quality and price. Hoping it works out - I want to keep this!

Internet Connection Lost Once 2nd Router Added to Network

I am at a point of complete loss and frustration and absolutely cannot figure this out.
About 4 months ago, I decided to add a 2nd router to my home network. I have a large house and was having connection issues in certain spots. My set up is:
Cable Modem ---(ethernet)--> Airport Extreme --(ethernet)--> Time Capsule
I have the network set up as a single network (Time Capsule extends the network). I followed all the Apple instructions and everything set up with ease and worked flawlessly. I was able to confirm that devices would switch from the Extreme to the Time Capsule depending on location. It was wonderful. Wifi bliss in my home!
Yesterday morning, I showed that I was connected to my wifi network but I could not get any data. Airport Utility showed Green Lights next to my 2 devices but an Orange light next to "Internet" with a status of Disconnected. I assumed it was an issue on my ISP side and went through a modem reboot and some other steps before confirming that I did in fact have an internet connection (hard wired ethernet from modem to MBP). I went through the same steps as before (after restores through the Airport Utility menu) and my wifi network comes back when the Airport Extreme is connected but as soon as the Time Capsule is connected, the Airport Utility shows that I am disconnected from the internet and I have no data transfer.
After hours of soft resets, hard resets, and factory resets including changing the name of the network and resetting/unplugging the cable modem I became convinced that the Airport Extreme was the culprit (I bought it "new" open box on ebay). So I bought a brand new Airport Extreme and the same thing happened. I tried various configurations including taking the Time Capsule out of the equation and going Airport Extreme to Airport Extreme and absolutely nothing works. Bottom line: Once I add a 2nd hard wired router to extend my network, I lose my connection to the internet and it says "Disconnected" at the top point of the Airport Utility. When I have a single router connected, everything works fine (I am using it right now).
Does anyone have any idea what would be causing this? I did not do any updates or anything odd. I just woke up one morning and something that worked for 4 months flawlessly is completely impossible to use.

I figured out the issue and resolved the problem. The Airport Extreme had WAN in from the Cable Modem and LAN out to the Time Capsule and to my DirecTV Home Cinema kit. I re-set up everything with all unnecessary LAN connections disconnected and it worked. I plug in the DirecTV LAN line and it all goes down again. It looks like the DirecTV Cinema device was frozen and causing the issue. Once I pulled the plug and rebooted it, everything went back online.
I have no idea why a frozen DirecTV Cinema device would cause this problem but it was definitely the culprit. Now I have an extra Airport Extreme. Sigh.

New iPhone 3g 16gb drops internet connection (must be reset)

I just picked up an iPhone 3g 16gb Black and love it. Its truely an amazing device, however I am having 1 major issue.
The Internet connection constantly dies on me...
As an example:
This morning woke up, and downloaded an app from the app-store using 3g. Drove to work, and then tried to check my email. The phone gets stuck in a connecting loop in the mail app. I switch to App-Store it stuck trying to connect. All the while the little swirling icon is going in the top bar.
The only way to regain internet connectivity is to reboot the phone or go into the settings and disable and re-enable the 3g.
I am in a 3g area, my previous phone, an AT&T Tilt never had 3g issues...
I love the phone but this is driving me crazy...
Anyone have any advice or help?
Thanks,
Rich P.

One thing that might help.
When checking for email and it seems to keep trying to connect, hold down the home button and keep down until the iphone goes back to the home screen.
Also, you can reset the iphone by holding down the home and power button at the same time until you see an apple logo.
Here are a couple of articles from the apple support website that might help out.

You might need to reset and or restore the iphone to resolve any software issues.
Hope this helps.

Just purchased Airport Extreme ac and lost internet connection 3X. Reset to factory settings and worked for 2 days then lost connection and remedied by unplugging power supply. Anyone else having problems?

Just purchased Airport Extreme ac and lost internet connection 3X in less than one week. Fisrt time, reset to factory settings and fixed problem. Has occurred 2 additional times and connection re-established by unplugging AP extreme. Anyone else having these problems? Do I have a bad router? Thanks.

I definitely think this is a Mavericks issue. My iMac running Mavericks is the ONLY system in the house that drops the network randomly while all other systems never lose the network. No idea how to resolve this, but here is the workaround I'm posting:
I've had the 'network drop' issue with my Airport Extreme for the last 2 months. It reconnects when I pull the ethernet cable and plug it back in. I've tried downgrading the AE firmware, resetting to factory, etc. Nothing worked. I finally threw in the towel and created a script that monitors my network connectivity and restarts my interface if it senses it has dropped:
#!/bin/ksh
while true
do
yup=`ping -c1 -t2 www.google.com|grep from`
if [[ -n $yup ]]
     then echo "Internet is connected!"
else
        ifconfig en0 down; ifconfig en0 up
        echo "Down at `date +%m%d%Y%H%M%S`">>./dropped.out
fi
sleep 5
clear
done
I know its a workaround, but its saving me the headache of constantly pulling my cable and putting it back in!
Good luck!
