Wrt54g2 v.1 drops internet connections 2 or 3 times a day.

Hi,
I just changed my old dlink router for the wrt54g2 and since I did the change, the internet connection drops a few times a day.
I'm not using the wireless, only wired. The dsl modem is connected and i entered my PPPoE info.
Everything works well execept the internet connection drops 2 or 3 times a day.
Can it be the "Connect on the demand" or "Keep alive" option that is causing this? I had it configured to keep alive: redial period 20 sec.
OR
Is my router defect?
I need a solution since this is configured in one of my stores and i cannot afford having the internet drop when i have a client.
thanks!
Humberto.

i am having the same issue with a WRT310Nv2 that i just purchased last night. it has firmware version 2.0.00 build 012 so i did not have to do any firmware updates. everytime it happens i go to status and says my ppoe authentication failed even though the usename and pass are correct. i right noe have it set to keep aliveredial period 30 sec.
like i said i have just purcased it hours ago and need a quick reply. otherwise i will return it for another brand. thank you

Internet connection switches of same time every day

Question relates to G4 iMac running 10.4.10.
Internet connection is USB modem, no LAN - works fine except that at 9.30pm every day it switches itself off.
I can't find any preferences or settings that would prompt this so am hoping someone can help...?
With thanks

Thanks ricckli
It's a straight-through connection via a USB modem.
The ISP is Pipex - I don't think they switch off but will look into it.

I have Snow Leopard 10.6.8 on my MacBook. Constantly dropping internet connection or message "error connecting to the network" comes up. No wireless connectivity issues with windows 7 laptop or iphone.

I have a MacBook with Snow Leopard 10.6.8. The last few weeks it has been constantly dropping internet connection, and one of these messages appear on the page: "Safari cannot open this page because the server where this page is located isn't responding" or "Safari cannot open this page because you are not connected to the internet" comes up. I will check Wifi and I am connected. No wifi connectivity issues with iphone or windows 7 laptop, this doesn't happen with either of those devices. I have unplugged and reset router, cleared cache, still happening. Any ideas? Thanks in advance.

Extreme Base Station suddenly dropping internet connection

I have an Extreme Base Station (802.11n Fast Ethernet) which has been providing wireless internet and printing to two imacs pretty flawlessly for several years. It seems to be a fairly simple network. DSL modem (to WAN port) and USB printer cable plugged into back of Base Station.
Several days ago, the Base Station began dropping connection to the internet every few minutes. If I connect the modem directly into the computer, I have no problems with losing connection. So, I began looking for solutions online and have been trying everything I could find to do. I've scoured the forums here, and everywhere and read a bazillion posts.
I've done a hard reset of the Base Station, I've tried different channels, I've unplugged, waited ten minutes, and replugged in a myriad of sequences, including unplugging both the modem (Zhone/Paradyne 6381-A3) and Base Station overnight. The only thing I haven't done is roll back the firmware (currently 7.4.2 I believe). I'm still experiencing the same problems and am at my wits end. I've spent hours now trying to fix it and need to do other things like shop for groceries and vacuum! So, I'm posting, in hopes someone might be able to point me in a more productive direction.
Is it possible the Base Station hardware is failing? What are the signs and symptoms? I hate to spend another $179 and still have the same problems.
Thank you.
Most kindly,
---Susan

Dear Bluenova - ( +or other interested readers+ )
I know that this reply is two months since this topic was initially posted.
This is a longstanding Airport Extreme ( AEBS ) problem that's been noted since 2006-2007.
It has been an ongoing issue for me -AND- I continue to experience it even after recently upgrading my AEBS.
I finally called AppleCare in mid-Sept. and opened a formal problem case report.
As of today (Oct 15, 2010) I still have an open & unresolved case with AppleCare.
The problem has been escalated twice -and- is now referred to Engineering Dept for research & resolution.
I was curious what steps or actions you have taken -and/or- if you still experience the problem.
_Readers Please Note_
Many users have posted messages regarding problems with Airport Extreme *+DROPPING CONNECTIONS+* .
However, with careful reading, it becomes obvious that many forum posters are not sufficiently clear
-and- often confuse or do NOT make the distinction between ..... DIFFERENT TYPES OF CONNECTION PROBLEMS.

If you suspect that you are having the *dropped internet connection* type problem,
YOU CAN CHECK & WATCH IT HAPPENING IN THIS MANNER
Set Airport in Menubar to *"SHOW TIME CONNECTED"*
. *- +and also+ -*
Open Airport Utility --> AIRPORT --> SUMMARY window
.... and leave it visible somewhere on your screen while you web browse.
Now, once the internet connection drops or is lost ...
... in the Airport Utility Summary window - you will see the loss of the assigned IP Address
. *- and -*
.... in the Menubar - the time connected will reset to 00:00:00
If you have a new or ongoing problem that relates specifically to ....
.... Airport Extreme – dropping or losing *Internet Connections* ... ( +not wifi connection type probs+ )
.... please let me know.
I would like to be able to correspond directly with others via email to share info
(such as what modems, ISP's, time of day or conditions with which this problem has been found to occur)
I will then be glad to pass that info on to AppleCare in trying to find a cause (and solution) for this problem.
If this issue was treated collectively maybe AppleCare would address it with more resolve & urgency.
I'll check back with this thread for replies from other interested users.

AEBS Dropping Internet Connection q 45 minutes

I have the new airport extreme base station. I bought it January and it has worked flawlessly for the past 6 months. recently, in the past week or so, I began getting a dropped internet connection happening every 45 minutes or so.
About my set up:
Cable modem supplying connection to AEBS via ethernet. VOIP box connected to AEBS via ethernet getting internet connection from AEBS. Playstation 3 connected via ethernet to AEBS. Airport Express base station linked to airport extreme base station wirelessly (of course) to share printer connection via USB. iBook G4 1.2ghz running Mac OSX 10.4.9
Trouble Shooting.
Originally I would unplug the cable modem for 30 seconds and plug it back in. This would reset the connection and i would have service again for 45 minutes. I decided to test whether or not it was the router or modem that was kicking me so I unplugged the ethernet cable coming from the modem to the AEBS and plugged it directly into my computer and turned off my airport connection, essentially hardwiring the ibook directly to the modem. I got kicked off again. At this point i drew the conclusion that it was the modem and contacted my cable company. After a bunch phone conversations that essentially accomplished nothing, they sent a tech out to my house. He replaced my old (3 years) cable with a brand new one to test out. I left my computer wired directly via ethernet to the new modem and this time DID NOT receive any drops in connection over a period of 4 hours. I reconnected the ethernet cable from the modem to the AEBS and reset my connection and decided to test out wireless. It dropped me again in 45 minutes. I left the cable modem connected to the AEBS via ethernet and unplugged the ethernet cable coming out of the AEBS that gos to my VOIP box and plugged my computer into the AEBS via ethernet and disconnected from airport on my computer. I was again dropped in 45 minutes. I reset my modem and unplugged the ethernet cable coming out of AEBS that gos to my Playstation 3. Again I was dropped within 45 minutes. After that, I reconnected both the PS3 and VOIP box ethernet cables and unplugged my computers ethernet cable from the AEBS and have just been using the wireless connection and resetting the modem every 45 minutes when it drops. Oh yeah and I forgot to mention that I plugged the Playstation 3 directly into the cable modem via ethernet and played online for 4 hours without interruption/disconnect. Anyways, I am back to square one. I believe based on the evidence above that the problem lies within the Airport Extreme base station router some how, but I have no idea what the problem is.
What happens when my connection is dropped:
I can be doing anything from using an instant messaging service to trying to load a web page using firefox or safari. Basically the page fails to load, i get a message saying it can't find the server. Usually at this point I will open up network utility and try to ping yahoo.com. It doesn't ping and says it can't find the server. I go to the modem and unplug the power for 30 seconds and replug it back in. As soon as everything back up I have my connection back.
What the cable company did:
They looked at their connections, including the fiber optic node for the area. They did not find any outages or problems within their system. They plugged my coxial cable into a modem/tester box (not sure exactly what it was) to evaluate signal received via coxial cable which they said was working properly. they checked my cable connection from house to street and didn't find any compromises in the wire/cable.
I have downloaded and installed the latest firmware for my AEBS. I am out of ideas. Can anyone help?
ibook G4 Mac OS X (10.4.3)
ibook G4 Mac OS X (10.4.3)

I had the same problem earlier this year with my cable carrier. At first I thought it was the modem so I replaced the Dlink with an Apple Extreme and it still kept happening. After some research on MacInTouch I found that using an earlier version of the base station software made the problem go away. So I never updated and all was well with the world. Till last week and now like you I am dropping connections every hour or so no matter what application I am running or what site I am on the internet.
A friendly tech admitted to me that there was a problem with the way the modem communicates with the provider and that they were aware of the problem but that there was nothing he could do to help me.
That is when I cured the problem temporarily by using the base station software from 2004. If I find an answer to the return of the problem I will post it. Please let me know if you find a solution.

Problem with Dropped Internet Connections on AE/Macbook

I have a dual band Airport Extreme connected to Comcast Cable. I use a first generation Macbook to access the airport. The problem is that I keep on getting dropped Internet connections. The signal strength is shown at the top rhs of the screen as being full strength (4 bars).
If I swap out the router for a Linksys WRT54G, running DD-WRT, the combination works perfectly without any dropped Internet connections. Also, If I connect the Linksys to the AE with the Linksys acting as a wireless client repeating the signal, then I can connect the Macbook to the Linksys again without any dropped internet connections.
There is something about the Macbook connecting directly to the AE. It happens intemittantly but probably multiple times a day and is very inconvenient. The only way to get it back is to reboot the router or stop/start the aiport on the Macbook.
I have tried just about every possible setup on the AE including splitting the 2.4 and 5Ghz radios into two separate ssid's and changing the channels. I am using the latest AE firmware. I have also taken the AE back to the Apple store and they have swapped it for a new one.
I dont get the same issues with my windows clients or my ipad (although i have experienced issues while steaming video - but I think that may be a different issue).
Any suggestions/advice would be greatly appreciated.

Use the advice in this thread to investigate the signal and noise levels that the Mac sees:
http://discussions.apple.com/thread.jspa?threadID=2347845&start=1
What you may see if an increase in noise when the connection drops.
If that doesn't show anything useful, it might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort menu bar item to turn AirPort off, then on again.
2) Try to select your Wi-Fi network from the AirPort menu.
3) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease". Note that the fix this step implements may be temporary.
6) In the folder /Library/Preferences ( _not_ <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
These steps may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.

WRVS4400N Drops Internet Connectivity with PORT SCAN

I just installed a WRVS440N router and it appears that every time a PORT SCAN happens, the router just shuts down and drops Internet Connectivity for about a minute or two, then once the PORT SCAN is done everything seems back to nomal?
I have heard many complaints about this router and wonder does anyone else have this issue?
I also have very erratic Internet connections speeds and I turened off the IPS feature and that seems to help. I am running version 2.0.8 Firmware.
If anybody has any tips or tricks to improve this router would like to hear. I can only say I regret buying this thing.

I suggest you to play around with the wireless settings on the router, Like changing the wireless name , channel and the type of wireless security.
This link will guide you;http://www6.nohold.net/Cisco2/ukp.aspx?pid=80&vw=1&articleid=3698
Also, you check the firmware of the router by going to the status tab on the interface.
Website you can check to download it.

Hello.
Since Updating to 10.9.5 Safari and the App Store drop internet connection periodically while other apps Mailplane and Epic Browser continue to work ?
Never had this problem previously running a Macmini Server 2010 with the latest Mavericks Updates
Tried reinstalling over my existing OS and seemed ok until I once again updated to the latest security and Safari updates
Any ideas ?
Using ethernet but wireless acts same,

Retina macbook pro with thunderbolt ethernet adaptor drops internet connection on open apps after waking

I recently started using a thunderbolt ethernet adaptor and every time my comuter wakes from sleep, all the apps that were open no longer use the internet connection. I have to restart each one of them for them to be able to use the present internet connection. any ideas?

So I've noticed similar behaviour on my Macbook Air. It's a slightly different set of kit, since it's connected to a Belkin Thunderbolt Express Dock (http://www.belkin.com/uk/p/P-F4U055/). I'm on my second one of these because first one went back because it kept on dropping the internet connection (sounds familiar?) - and it *might* have been occurring when waking the system from sleep (I didn't make a mental note).
Anyway the replacement was working perfectly, until today - when it's started to drop it's internet connection again, and this time I'm pretty certain that it's related to waking from sleep. The main difference now is that I *just* upgraded to Mavericks, and I wonder if the sleep problem has reared its ugly head again in the latest version of MacOS?
All in all I have to say I'm pretty disappointed with the reliability of thunderbolt & the Belkin Dock thingie. Although it should be said that a single lead from my Macbook Air to the Express Dock is simultaneously carrying: video (1920x1200), Firewire800, 3xUSB3, gigabit ethernet and sound, so I'm not that surprised this technology is prone to the odd glitch, and the cables get really warm too!
It would be great to have some solid information from Apple/Belkin about this.
Cheers, Jon

Airport Extreme drops internet connection several times a day

I have an AE that is about 3 years old and it has worked great until the last two weeks or so. Over the last few weeks it will be working fine and then drop my connection for no reason. I will get an amber light on the AE although the cable modem stays connected. It is as if the AE is rebooting itself about a dozen times a day for no reason. I was looking around a bit and I see several things in the log at the same time that say:
Jul 10 10:09:47 Severity:5 Connection accepted from fe80::21c:b3ff:fe71:762f%bridge0:49424.
but I am not sure what (if anything) that means. I have a Mac, Win & PC, XBox, PS3, Two IPhones, and an IPad connected to it if any of that matters. I also make sure the AE is sitting out in the open with plenty of airflow to stay cool.
What do I need to do to make the connection more stable? Is there a way of reloading the firmware on the AE to see if that will help?
Thank you for any help.

ElksSS01, I have the EXACT same problem with my Airport Extreme but, I am 100% certain it is my service provider... The problems started for me back in March of this year, I've replaced my cable modem 3 times, Bought a new Belkin Router (didn't work either), had technicians come out to my house 4 times and FINALLY they found that they are reading voltage on the COAX line into my house, they traced it all the way back to their junction box in my neighbor hood so I asked my neighbors if they were having similar issues with the same service provider, which they were... So now I am back to using my Airport Extreme again, but using the Logs to keep track of how many times the connection drops...
When your internet goes down, try observing the cable modem, there should be a CABLE LED indicator, if it is not on SOLID while your connection fails then it is more than likely your service provider... Below is exactly what happens to mine...
1) no connectivity from any device, wired or wireless
2) cable light on modem turns completely off
3) cable light begins to blink
4) cable modem reestablishes a connection to the internet
5) AE light goes from solid green to blinking orange for 2-3 seconds
6) AE light goes back to solid green and all is well, for about 45 minutes in my case
I would definitely do what Bob Timmons sad above as I also thought it was my router and jumped the gun to buy a new one, only to find out it wasn't my router after all... Before you replace your AE though, I would check with your service provider... In my case, whenever I called them they said that my modem and everything looked fine on their end... In the event their is voltage getting fed back into your modem via the COAX, the only way they will be able to tell is by checking the lines, and tracking it back to where ever the faulty equipment is located...
Here is what I am dealing with, this crap gets VERY annoying... (removed ISP address for obvious reasons) and this isn't my entire log, actually it isn't even a quarter of it... Every day, I drop a connection at least 20 times... The log I keep is NOTHING but what you see below...

I have a Airport Extreme that is dropping the wireless signal alot (several times a day). The green light will go amber but the internet service (ethernet cable) will still be fine. The wireless icon on devices with go away.

I have a Airport Extreme that is dropping the wireless signal alot (several times a day) The green light will go amber, but the internet service is still ok if your using an ethernet cable directly plugged in. When the light goes amber all devices that is using wireless will lose there wireless icon. The only way to get the green light back is to unplug the Airport device and replug it back in. I tried the reset on the back but still no luck. What is the fix?

Let's see if I can get this straight.
You have an Airport Extreme base station that is set to "Create a wireless network" and you have the box checked for "allow this network to be extended"....
Then you have an Airport Express that is set to "Extend a wireless network" which you selected the name of your network in the box...
Correct?

Windows APP without real internet connection stops working in time

Windows APP without real internet connection stops working in time
Hello all,
I am trying to get the following to work. We have an intranet page which users need to connect to, to operate some machines. This is done through an windows 8.1 Tablet with an assigned KIOSK mode app (Kios SP Browser).
This works great as the assigned app is the only thing the user can run and we don't have to really harden the device. One drawback in using the assigned apps is that it needs to be an New App (as Microsoft call it)
The app is installed on an reference machine which runs in workgroup mode (no domain connection is needed on the devices) and after the reference machine is installed it is imaged with the use of Acronis. After deployment the tablet has no connection to
internet and the intranet page is wireless put available to the tablets. As a side note, the tablet operates with local accounts and the app is installed using an corporate hotmail account we created just for this purpose.
I now deployed the image over 20 different tablet devices and this worked great until recently a few devices start to complain it needs to connect to the windows shop before the app can be started. As the devices don't have internet access this can't be
done and the tablet is rendered useless for the user.
How can i make the app available without internet connection ? and how can i be sure the app will continue to work over time without connection to the store ?

Thanks for the reply.
I can't unblock the internet connection as the wireless network doesn't have any internet connection what so ever. The main purpose is to be able to operate the machinery and nothing else, hence the kios app which is being used to show the intranet page
which connects than to the devices.
The problem is that after imaging the app works as expected but after a few days the app stops to work ...
I found the following website over site loading an app without the needed appx files. It shows an way to capture the files during installation from the windows store.
https://www.404techsupport.com/2014/06/installing-free-windows-8-modern-apps-without-the-windows-store/
It is a bit strange to have it this difficult to install apps without the needed store and i think that Microsoft should make this easier. I hope this works better and after a few days i will give the feedback how this handles..
If anyone knows of a better way .....

Dropped internet connection

I had connection problems with my wrt54g2 v1 router. If I connected from the modem directly to the computer I had instant connection. I tried switching cables between modem & router & computer but couldn't get connection. So I bought a new E1200 router and swapped out the old one. Connections were good for 2 days, but now I'm having the same problem. I turn on the computer and I have no internet connection. I run the Cisco Connect but it doesn,t connect. As long as I bypass the router,
I have a good connection, but I need the router for wireless devices in the house...
Any suggestions????
Solved!
Go to Solution.

Hey Jacksweeley! How's your wireless connection? Does it drop along with the router's wired connection? Better upgrade the router's firmware then reset and reconfigure the settings. I do the manual configuration instead of running the setup software, I suggest you do the same thing too.
Here are the steps:
1. Press the Reset button for 30 seconds while the router is powered on. Then unplug the router from power for 1 minute afterwards.
2. Connect the router to the modem and connect the main computer to the router's port 1.
3. Open a browser and type or http://192.168.1.1 on the Address bar. Leave the Username blank and type 'admin' for the Password.
4. Go to MAC Address Clone sub tab, enable it and click Clone My PC's MAC, and hit Save Settings.
5. Configure the wireless settings and secure the wireless network with a WPA/WPA2 Mixed security.
Hope this helps!

Dropped internet connection in Vista 32

Hello,
I'm running a MacPro. While running in Vista 32 under boot camp my internet connection drops out. When I first boot up, My internet connection is perfectly fine. However as time goes on the connection drops and takes a re-boot to get it working again. My connection is fine in OSX. I get my internet through a cable modem, which is run through my Vonage router, then to my computer via ethernet. I have tried many things. I installed the new drivers for bootcamp 2.1, I have adjusted the power settings so the ethernet card never sleeps. I'm looked around online and there weren't any known incompatibilities with my Vonage router.
Any Suggestions?
Thanks in advance

Cisco ASA 5505 - Keeps dropping internet connection

Hi,
We are having some issues with our Cisco ASA 5505 unit, it intermittently drops the outside interface connection. Internally the network appears to be working correctly with no issues. Even though the outside interface indicates it is 'up' access to the internet is lost from our LAN. This seems to be ocourring more and more often! This is happening for all users on the network too. Reloading the ASA seems to correct the problem temporally but this isn't really an option during peak periods in the day as this would obviously hinder work being carried out by employees.
Any ideas?
Any help would be greatly appreciated!!
Thanks,
John

Hello,
What happens when you assign eth0 as internal interface and eth1 as outside if?
Also configure logging (/debugging) to see if there are hardware issues or something else.
And it seems you have a range of public addresses. What happens when you connect a device, e.g. a laptop directly on the internet access device and send continue ping to an internet host.
When you loose internet connectivity, is the laptop still pinging to that host?
Hopefully this helps you,
Kind regards,
Ralph Willemsen

Wrt54g2 v.1 drops internet connections 2 or 3 times a day.
