WRT54GL frequently drops WAN connection

Hi,
I'm having a problem with my WRT54GL 1.1 router, namely it has a nasty habit of dropping WAN DSL connection. Firstly I attributed this to modem, but my ISP's tech support sent me a list of connection resets that are caused by the router not the modem. This happens about 20x a day, lasts for about 20 sec, then reconnect, works fine for a while and the whole cycle is repeated again. As you can imagine it is very frustrating.
I have the router upgraded to firmware rev. 4.30.11 and am using router's DHCP server.
Also: before you suggest it - I have connected my IskraTel Ganymede 822+ DSL modem directly to my PC and the connection is completely stable.
Any suggestion would be appreciated.
With kind regards,
Bostjan Ursic

It is difficult to be sure from the documentation, but it appears that your "DSL modem" is actually a "DSL modem router", and it uses the same 192.168.1.x subnet as the WRT54GL.
To fix your problem, you will need to make one or more changes. First, power down your entire network, then disconnect the WRT54GL from your modem. Then wire one computer to a LAN port on the WRT54GL, and login to the WRT54GL. Change the "Local IP address" to 192.168.2.1   Then click the "Save Settings" button and wait (3 to 60 seconds) for the screen to refresh. You will likely be disconnected from the WRT54GL. This is normal, so do not worry about that. Power down your entire network.
Next, using an ethernet cable, connect one of the LAN ports on the "modem" to the Internet port of the WRT54GL.   Boot up your system. Did this correct the problem?
If you still have problems, please post the following info:
1) What "Internet Connection Type" is the WRT54GL set to?
2) Is the DHCP server turned on in the 822+ modem?   (Note: I assume that the DHCP server is turned on in the WRT54GL.)

Kludgy fix for T520 frequently dropping WAN connection

There's no obvious way to lodge a bug with Lenovo. Hopefully someone from the tech dept looks in here from time to time.
The problem:
T520 (4242CTO) running Win7x64. Accessing WAN (Telstra NextG 850Mhz HSPA) via F5521gw. Connects initially without issue. Then drops connection after random time interval. Doesn't matter whether connection active or idle. Persistently fails on any/all reconnection attempts.
The fix:
In Control Panel/Device Manager, disable "Network adaptors/F5521gw Mobile Broadband Driver" and "Ports (COM & LPT)/F5521gw .... (COM4)". Then reenable same. Reconnects on next attempt every time.
Presumably there's some issue with releasing/renewing authentication/IP etc. Perhaps something to the effect of resetting the adaptor could be trialled for inclusion in future releases of Access Connections?

MacBook Air + Time Capsule frequently dropping internet connection

I too have been having frequently dropped wireless connections between my MacBook Air (MBA) and my Time Capsule(TC). My TC is connected to a cable modem and I also have an Airport Extreme Base Station (AEBS) at a different part of my house which is used to extend my network connecting via ethernet to a PC running VISTA, and wirelessly to a printer and an older MacBook. I also connect wirelessly to my home network with two iPhones, a Squeezebox 3 with a server running on the PC. I have an Apple TV and a Squeezebox 2 connected to my TC via ethernet.
When my connection drops I will either see a Time Capsule disconnect message or if I am surfing the web, the browser just hangs. The wireless ICON strength is still pegged a the max level. None of my other devices (wireless or ethernet) connected to the TC or the other AEBS seem to drop their internet connections. I can re-establish the connection on my MBA by either turning off my MBA's Airport wireless and then turning it back on or by running the network diagnostics. The latter method usually shows green lights for all but the "Internet" and the "Server" which will have yellow lights. Usually when I select my wireless network and press continue, it will prompt for my WPA2 password which I have to reenter even though I always check the box for it to remember the password in the keychain.
After reading the various discussions on disconnect problems and trying the various "solutions" I was still having the disconnect problem.
Last night, I decided to turn off my Time Capsule and was then able to maintain an internet connection for considerably longer than before. Perhaps it was one of the other "solutions" that caused that. After turning my TC back on, the disconnect problem reoccurred within about 5 minutes.
Next, I did my too frequent Time Capsule remedy which was to disconnect the power and then reconnect the power. (Seems like some of these devices (APPLE TV included) could use power switches.) I then deleted the .sparsebundle backup file on the Time Capsule. I was then able to restart Time Capsule backup and things have been running uninterrupted for over 12 hours...still backing up (20GB in 12 hours? Doesn't seem very fast!). I can report back later if this actually "fixes" my disconnect problems in the future. I am dubious that it will.
I have several questions about the MBA and the TC/Time Machine backup operation.
1.) I often forget about the TC when I close the lid on my MBA and haul it off to work. At work (connecting via ethernet), I will eventually get a TC disconnect error. But I am wondering if there are points in the backup process where a random disconnect will cause some sort of TC corruption. What is the recommended way of handling this? Should I always stop the Time Machine backup before turning off my MBA? (A nuisance if so!)
2.) What is happening when the TC backup operation stops functioning and hangs up the MBA's internet connection? (I see lots of messages logged in the system log when this happens; but, of course, I don't have much of a clue of which ones are normal and which are not normal. I could send a copy of the logs when it happens next (I am assuming it will).
Also one other anecdote. A few months back, I had taken another AEBS to my work to use during a training conference. My MBA kept dropping its connection while the other PC laptops in the room maintained their connections...(very embarrassing!). Maybe one of the other "solutions" would have fixed the problem or maybe if I had just turned off my Time Machine backup it would not have disconnected. I will repeat that exercise when I get a chance now that I have some things to try.
It seems pretty clear to me from my own experiences and the discussion reports of others that the disconnect problem lies in the MBA's wireless internet connection software or the configuration of it. It seems like it is having difficulty recovering from various wireless connection "mishaps".

Folks, I was having a very similar problem for the last 6 months. My connection was fine until June 2008, after which my Macbook and my Time Capsule would constantly conflict. If I rebooted or reset the TC, or the MB, things would be fine for a few minutes or sometimes a few hours and the problem would recur soon thereafter. About a month ago, I had to do a clean reinstall and the problem vanished for about 5 days, after which it reappeared. My MB never had a problem at work, or at someone else's home or with other routers, only with TC. Apple sent me a new TC, then they replaced my Airport card but the situation did not change ... UNTIL ABOUT AN HOUR AGO.
An hour ago, I called Apple for the nth time in the last 6 months, and the rep heard me out (just like the previous n-1 reps). He then asked me to to System Preferences --> Accounts --> Login Items and asked if Real Player Downloader showed up in my list. Indeed it did. He asked me to remove it, and told me that Apple had just figured out that the Real Player downloader was recently found to be causing a drop in the connection between Macbooks and the TC (as well Airport Express).
The problem I've been having baffled everyone. All the previous reps, the guys at the Genius Bars, nobody had a clue. Joe (the rep I spoke with this morning) seemed very confident that the removal of the Real Player Downloader from the list of login items would resolve the problem. So far, so good. My connection seems solid (its only been an hour, but earlier it would drop after 5 minutes of use).
I hope my problem that (literally!) used up hundreds of hours of my time has been finally resolved. I hope this solution will work for at least some of you as well. What gives me hope is that this solution is logically consistent with the history of my problems. I probably first downloaded Real Player in June 2008. And when I did a clean install, I remember downloading Real Player a few days after the reinstall. So I'm pretty hopeful that my issue has been finally resolved.
Shame on Real Player for putting out a defective piece of software. And thank you Joe!

SA 540 drops wan connectivity after some time interval

hello guys,
I have problem. after a certain period of time (ranging from 2 minutes to several hours) the unit keeps dropping the WAN connection, making the unit unaccessible from the WAN side. The strange thing is, that when the connection is dropped, the unit is perfectly accessible from the LAN side, the WAN LED is still on, status info shows the WAN link up, and packet trace shows broadcasted traffic on the WAN interface, so only the directed communication to and from the ISPs gateway (configured to fix IP) seems to be blocked for some reason. When this happens, then plugging the WAN cable to the Optional WAN port enables traffic again, but it is also dropped after some time, and then only power cycling the unit restores WAN connectivity.
please suggest me as soon as possiblethat how to fix this problem?
Awaiting for valuable reply.....

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

WRT610N Frequently Drops Wireless Connections

Hi,
I have a WRT610N V1 that seems to have wireless issues. It frequently drops all of the wireless connection - not the IP address leases. An then we can't reconnect for some time, even after rebooting both the router and the modem. I just upgraded the firmware and did a full reset, but that didn't work either. Any ideas?
Solved!
Go to Solution.

This could be caused by intereference with nearby routers.
Have you tried changing the channel on the router?

SA540 - Continuously drops wan connection

It's been nothing but a nightmare since i've gotten the 540. My firmware is 1.1.42 and I have a very basic setup with only a couple of standard firewall rules. The 540 keeps dropping the wan connection. Everything is static on the LAN side and DHCP is turned off on the 540 with Static IP for the WAN. I've factory reset twice and reconfiged everything exactly the same with of course the same results...help!!!
Thanks
James

This is probably worthy of a case with high priority at the SBSC (small business support center - aka TAC).
That is the new FW and you have factory reset so sounds like you have dont everything they way you should have.
There are a few things to try...

Firewall -> Attacks
Under ICSA settings, uncheck the box for block fragmented packets.
Also, lower the MTU size and see if that helps (usually do this for DSL).
Also, see if you can collect a WAN trace (easy on this appliance) using Administration: Diagnostics: Packet Trace (turn it on, catch the anomaly, then turn it off). This will open into Wireshark (formerly Ethereal) right on your PC.

LRT224 hickups: dropping WAN connection??

Hi,
my new LRT224 shows hickups in my connection.
It is hooked up to a 100Mbit fiber connection from my isp.
If I try to stream video, it creates every minute or so a second or two pause in the transmission.
Clearly, this breaks my continuous video stream.
The device log (shown below) does report 'WAN connection is down', which seems rather strange and unexpected to me.
If I don't stream video, and the data link is nearly idle, these intermittent 'WAN is down' messages do continue.
If I take the LRT out, and connect my PC directly to the isp line (yes, bad practice) I don't have such hickups, and the video streams fine (at a few mbit/sec).
I updated the firmware to v1.0.1.01 but that didn't make a difference.
I actually disabled the 2nd WAN port.
In the 'dual WAN' config, the 'Enable network Service Detection' is not marked. Selecting 'Link failover' or 'Load balance' does not show any difference (no improvement).
Any clue why the LRT would report 'WAN connection is down'???
I urgently need some solution, but the issue seems beyond my skills...
(In the log I also see 'policy violation's. I have no idea why these occur: I have no firewall rules on those LAN or WAN IP addresses...)
Thanks for any insight!
Jos

Frequently Dropping Broadband Connection- Amber an...

Hi, This is my first post of this forum as it looks like a place I might get some help on the problem I have had for months, I will try to explain my problem as much as I can.
Well it started when I came back from my holiday around 5 months ago, never thought much of it until when I started to browse the net it would come up saying ssl error and take me to bt wizard sort of thing say Can't Connect To Broadband with the amber/purple light flashing. it is enough to boot me of everthing skype chat, xbox live browsing and is getting really annoying. there is no pattern when it does just complete randomess when it does do it.
I have been on the phone with bt several times with just no luck, i thought i got somewhere when they put we through to engineer department or whatever it was called and heard nothing since, i have changed the microfilters checked power cables, don't think it is the router really, i am just completly stuck on what is happening so any help would be amazing.
it is also showing this error in the event log which I don't have a clue what it means.
WAN connection WAN1_INTERNET_B_ATM2_0_35 disconnected.[ERROR_NO_CARRIER]
thanks for taking time to read this and I really hope you can help.

Hi JasonKirk2013,
Sorry to hear that your having issues with your BT Retail services.
You will either be on the ADSLMax (upto 8mbps) service or if your exchange has been BTw 21cn upgraded you maybe on the ADSL2/2+ (upto 12/20mbps) service depending on your line quality and length.
However these upto speeds may not be the speeds you will get as ADSL broadband connections are very dependent on the distance from your property to the exchange and the quality of your line. The further away you are from your local exchange the slower your broadband speed will be.
To enable the community to help you please see the advice below:
Please see Keith's help guide here: Helping forum members to help you, it will go through some checks that are needed for us to help you.
A summary of the checks are:
1a) Is your router/Homehub connected by a BT NTE5 master socket, Adsl Filtered Master Socket or Extension Socket? Please bear in mind that extension cables and extension sockets can reduce the broadband's performance. If you have an Old LJU master socket then please say.
1b) Have you tried the Test Socket? - if you have one.
2) Can you please run a BT speed test (including IP Profile) http://speedtest.btwholesale.com (not beta version)[Best done with a wired, Ethernet, connection] After Quick Test is done you need to click "Further Diagnostics" to get IP Profile.
3) is there any noise on your line. dial 17070 option2 ,called quite line test, from landline phone. should be silent but slight hum normal on cordless phone.
4) please post adsl line statistics
5) does the distconnections happen when you use the landline phone?
ADSL Line Statistic Help:
If you have a BT Home Hub like the one below...
Then:
1) Go to http://192.168.1.254 or http://bthomehub.home
2) click Settings
3) Click Advanced Settings
4) Click Broadband
5) Click Connection or sometimes called ADSL (see picture Below)
The direct Address is http://bthomehub.home/index.cgi?active_page=9116 (for bthomehub3.A firmware ending in 1.3)
or http://bthomehub.home/index.cgi?active_page=9118 (for bthomehub3.A firmware ending in 94.1.11)
You will need to copy and past all the adsl line statistics ( Including HEC, CRC and FEC errors). You may need to click " More Details"
If you have a HomeHub 4 then the majority of the ADSL Stats shown in the previous Hubs will not be there.
for HH4 users you can go to hub manager then select troubleshooting then logs and are look for 2 entries together which will show theconnection speed and noise margin for when your HH4 last sycned with the exchange.
There are more useful links on Keith's website here: If you have an ADSL connection, please select this link
Don't have a BT Homehub/Voyager?
• http://192.168.0.1 for a netgear router and look for ADSL adsl statistics with information like noise margin and line attenuation, connection speed
• http://192.168.2.1 for a belkin router and look for ADSL adsl statistics with information like noise margin and line attenuation, Data Rate

I'm no expert, so please correct me if I'm wrong

Rv042 v4.1.1.01-sp drops wan connection

I recently implemented the rv042 as a replacement for a wrt54gs running DD-WRT. I upgraded to the latest release (v4.1.1.01sp) to solve 6to4 and SIP problems. These problems were indeed solved. However after some minutes the WAN1 connection gets somehow disconnected from the ADSL modem.
It does show the public ip address, but I cannot ping the ptp router anymore. I also cannot renew the lease. Rebooting the rv042 does not help. When rebooting the modem it briefly works again, but then loses the connection again and it never comes back.
Currently I returned to the old wrt54gs as a workaround. Because I am planning on an extra WAN connection (via cable), which is the main reason why I bought the rv042, I am eager to get this problem solved quickly. Since the ADSL modem is pretty old, I ordered a more current one that also supports IPv6, so I do not have to use a 6to4 tunnel. I will test again with this new modem, but I doubt that it will solve my problem since I do not have any problems with the old router.
Has anyone seen this type of problem, and can I do something in the configuration to solve this? Or is it just a bug?
Thx,
Hans Feringa
I replaced the ADSL modem. That fixed the problem.

RV082 drops WAN connection immediately after establishing it

I have my 2nd WAN connection on the RV082 setup to connect via static IP to a T1 connection. When I connect the cable, the log reports...
"WAN connection is up : 216.130.xxx.xxx..." and 3 sec's later reports "WAN connection is down".
I can connect a computer directly to that T1 with the same static IP settings and it connects without a problem.
I'm on the firmware version v4.0.2.08-tm.
Any thoughts?

I was using Smart Link Backup. Changing to Load Balanced brings the other WAN up. Is that normal behaviour? That if you're using the Smart Link Backup it shows the backup WAN interface as being down (in the logs) and no IP info (all 0.0.0.0) in the WAN status.
If the primary WAN goes down, will it then auto bring up the back WAN interface?
I'm on v4.0.2.08-tm firmware and i also changed the MTU to 1492.

Dropping WAN connection

We have installed a new Time Capsule running Version 7.5.1... Running both Ethernet and Wireless connections from a DSL modem for WAN connectivity... We are getting continuous (2 to 3 times per day) WAN disconnects... the router works fine just that we all lose our internet access...
We have several ports open for external access to various accounting package and operational databases...
Thinking it was the phone company we had them replace the DSL modem with their most current version and still have problems....

I had a replacement TC sent - it was worse - returned it.
I placed it behind my LinkSys router - still dying.
I spoke to support again - that had one "expert" calling me - what an arrogant SOAG, at some point he said - "end of conversation" and slammed the phone.
He had never heard of the problem - "most be the ISP's equipment or my LinkSys".
Tried to explain him that i'm not the only one - just check apple forums - that the TC has problems with my Siemens fiber modem (LinkSys doesn't), and even placing my Linksys router between doesn't help.
For me this all indicates that the firmware on the TC is not stable - he argued that this is not the case, this is a compatibility issue. I agree that it might be a compatibility issue - but the root cause is still the firmware of the TC.
He wanted to have me to try the TC at a different location with different ISP - but for me that would just show that the TC works in some setups - but for him that would 100% clear the TC of any blame - that makes no sense.
Am I wrong - or is the "expert" wrong - give me your opinion, thanks.

Airport Extreme(SW) keeps dropping the WAN connection under "heavy" load

Hey,
Have had this problem ever since I got the Airport Extreme when it first came out and I got it.
The problem is this : The connection will work just fine for ages, but if I end up downloading something using (primarily this is the problem) torrents and I end up getting a rather good speed on it the airport will all of the sudden stop getting data from the WAN(ADSL modem connected to it through the WAN connection) and the Airport will have to be restarted. Some days it will have to be restarted up towards 15 times a day.
The Airport remains accessible through the LAN connection, as well as through the WiFi when it has failed like this so I can go in through the Airport Admin Utility and restart the unit without any problems whatsoever. The modem does not need restart or reiniting either.
The problem occurs no matter of if I am on the hard wired (LAN) connection or the WiFi connection. If I download something using a torrent that is high speed, especially if its more then one torrent at the same time (say 4 torrents each running at 200-300kbps therefor peaking at the roof of what my DSL connection can handle) then it will absolutely lock up after a minute or so. If I only do surfing or 'ordinary' work then there is no problem.
The problem is easily repeated.
* If I connect my laptop by wire to the modem directly without the airport in between there will be no problem.
* I have software reseted the Airport many times to attempt to fix the problem when it has gotten on my nerves with no positive or changing result.
* I have the latest available from Apple firmware(5.6) installed on the Airport.
* I have no 'weird' or abnormal settings set on the Airport, and no neighbors playing tricks on me - This problem was with me when I used the airport fully locked down in a office environment and then went with it when I moved my airport unit out of my office in to my home.
* I have no other wifi units in the house that may cause problems, no bluetooth phones running amok.
Airport details:
Apple Airport Extreme Base Station
Firmware Version: 5.6
Wireless Security : Not currently enabled
Wireless Channel : 1 (automatic)
Built in modem : No
Prod # : M8930LL/A (A-1034)

Hi guys,
Recently I bought AirPort Extreme 802.11n Base Station (Gigabit, MB053LL/A), and
seems, I have very similar problem with yours. Internet connection from my ISP over WAN is dropped after few hours of being idle. The router successfully receives its IP settings from provider's DHCP, eveyithing is working fine at first and as long as I have some inet activity. Then I disconnect, or sleep my laptops, and when I'm back - WAN provides no Internet traffic at all It looks like WAN is not functioning or blocked in someway. AirPort Utility and logs show no problems, all statuses are good, correct WAN IP settings are shown in the utility.
Sometimes it helps to plug-out/in Ethernet cable to WAN port, but more often only full router restart helps (with around 10-20 secs of outage). BTW, WiFi connection between the router and laptops is pretty stable and causes absolutely no probs. HDD connected to the router works good also.
My firmware is 7.2.1 (gigabit), and reading above posts I tried to downgrade to 7.2. It didn't fix the problem So well there are no earlier firmware versions for this AEBS model to try.
Does anybody have ideas about it?
(I understand you guys mostly wrote about 100Mbit version of AEBS)
Thanks you,
Strim

WRT120N - Dropping wired connection frequently

Today alone I have dropped connection 6 times. I recently purchased this router because I thought my WRT54G was kicking on its last leg. It would dropped connections every 45 minutes it seemed.
Now I am experiencing the same issues with this router which is brand new. I have tried power cycling the modem and router. I have made new cables for my devices I am connecting (PS3, PC, DirecTV receiver) I haven't tested things with just going with the modem seperately for security reasons, but I have contacted my ISP to see if anything was wrong with the modem. They have told me that nothing is showing up on there end.
What else could be causing this?

I changed the setting and I am still getting drops in connections while on the internet and PS3. Since the morning of the 9/10/09 up until today, I have dropped 14 connections. Though they only last maybe a second or two, it is still inconvinient.
This happened frequently while trying to play my PS3 online, so I disconnected from the router and plugged the PS3 straight into the modem. I didnt have any issues while playing my PS3. I plugged the modem back into the router and got on the computer for a few hours and the dropped connections started again.
I am honestly at a lost with this.

WRT%$G dropping wired connect frequently

Trying to setup a wireless internet with WRT54G v.3 ( using latest firmware 4.2.1 1/30/2007) on Comcast IP w/VOIP modem (Arris TM502G). Seems to work fine when using only MAC address specific. However when adding WEP encyyption, it frequently drop the wired connection. Sometimes the drop is momentary and it reconnects itself. Other times, I have to restart the router. I've been through much of the forums and have spent much too much time on the issue. Problem remains. Currently using borrowed Actiontec MA424WR without issue. Please help would like to get the WRT going so I can return the Actiontec. Thought maybe your technical crew will have an answer for me...thanks Paul

I assume you mean you are using 4.21.1 firmware.
After a firmware upgrade, you must reset the router to factory defaults, then setup the router again from scratch. If you have not done this since the last firmware upgrade, then please do it now and see if it corrects your problem. If you saved a router configuration file, DO NOT use it.
Also, many users have found that WPA works better than WEP. Please try WPA encryption.

E3000RM - WAN connection dropped

Pros: Good Price. Worked very well when it did operate.
Cons: I purchased this approximately 5 weeks before I got around to using it. After installation, it worked for two days and failed. The WAN connection dropped, and numerous attemps to reconnect failed. Since I was approximately one week past the expiry date of the warrenty I guess I am out of luck and learned a lesson to test upon receipt.

In this case you can reset the router and try to run the cisco connect software that came along with the router to reconfigure it (Note: If you already have cisco connect on your computer then uninstall it first before reinstalling it.). After that you can get into the advance settings of the router through cisco connect and try to reduce the MTU size to 1400.
Click on the following link that shows how to reduce the MTU size http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=66270e5d0d4347d087102f2bfef7116d_3742.xml&pid=80&r...
