Frequent Connection Drops - Please Help!

    I just bought a WRT54G v5 a week ago..and since then I have been experiencing frequent connection drops. Its not the wireless signal, its the connection to the PPPOE server itself. It gets randomly disconnected, like twice a day, and only comes back after 20 seconds (the Keep Alive Period)

    What is happening? Can anyone enlighten me with a solution? I have the latest firmware version already! Why does my router keep getting disconnected? Its surely not an issue with the PPPOE server!

    Thanks in advance!

    Versions 5, 6 and 7 suffer from abnormal disconnects, from what I have read in other forums. I dont know for sure but it may have to do with the reduced RAM and Flash Memory. I have a WRT54G v3 and a WRT54GL v1.1, have not suffered any disconnects as of yet.

    From what others and Linksys support says is to upgrade the firmware. They think that solves all problems but sometimes makes things worse. I would suggest a reset back to factory defaults and reconfigure the router to see if that helps. Maybe clearing the NVRAM will help.

    WRT54GS v5 problems with satellite too

    I have a 1 month old WRT54GS v5 with similar problems. My Wildblue satellite modem is very reliable, but I find that I have to reset the darn router 2-3 times a week. Once it is reset it works fine. I have never had to reset the modem.

    Recently I have also had to reset, hold the reset button in for 30 sec, my WRT54GL ver. 1.1 with the Linksys 4.30.2 firmware about once every 1 or 2 weeks. It drops the PPPoE connection and refuses to reconnect.

    If I take a laptop with Windows XP, OSX, or Linux and connect directly to the DSL modem and configure the laptop for a PPPoE connection it works fine.

    As soon as I reset the router then reconfigure all of my settings in it, the router is back working again.

    How old is your GL? The GL's sold now come with FW version 4.30.7 and are pretty stable. Since Linksys FW is so buggy for what I need I immediately switched to DD-WRT when I bought it and my version 3. If you dont want to risk voiding the warranty if you still have one you should try the 4.30.7.

    To get it log into http://www.linksys.com - Under the Linksys logo on the top left of the home page shows your location. United States as our case. Next to it is [ Change ]. Click on that and choose United Kingdom in the dropdown in the next window. Then go to Support / Downloads and choose WRT54GL v1.0. Down load version 4.30.7

    I think I recieved the WRT54GL ver. 1.1 in either April or May of this year from Linksys as an RMA exchange for a WRT54G ver. 5

    I see that the US download site has firmware 4.30.5 for the WRT54GL and the UK download site has 4.30.7

    According to the description of the firmware I am not sure if 4.30.5 or 4.30.7 will help with PPPoE issues.

    You play games, or do torrents? Games, etc. tend to open a lot of connections, which could max out the ip conntrack on the NAT - don't know how to solve that on stock firmware.

    You can upgrade to 4.30.7 ETSI if you are in the US. Just don't use channels 12 and up if you want to stay good with the FCC.

    If you connect directly to your modem you are most likely not doing NAT, as your PC now has an internet address. If so, no conntracking neccessary, therefore no maxing out of it. If you run NAT on the PC - the PC has much more RAM than the router, so if the PC is doing conntrack, it'll take a lot to max it out.

    The firmware track log is usually very skimpy in detail, and it may be that something was changed that's not mentioned in the log. Recommend upgrade to .7 anyway.

    Best to go to third party firmware, which give you control over some things that stock firmware don't.

    @Onyblacksun: Forgot to mention - some ISPs deliberately drop the connection in order to do usage counts. In South Africa, the ISPs do that about every 24h.

    Hi HennieM:

    No I do not play games. But I sometimes download iso files to try a different version of Linux.

    Strange though, this only started last month. I have had this WRT54GL since April or May of 2006 and it has been working perfectly.
    I went back into the router and enabled the log. So we shall see if that helps identify what is going on.

    And to Onyblacksun

    Sorry did not mean to hijack your thread. :)

    Too bad we did not know that you were in the process of purchasing a router last week. Maybe we could of talked you into a WRT54GL which runs Linux and not VxWorks. :)
