WRT54GS v4 thibor15c - Frequent PPoE disconnects, no auto-reconnect?

    that's it really. i have this posted in the hyperwrt.org forums, but i've nt had any replies yet so i thought i'd try my luck here.

    i have a WRT54GS v4 running thibor15c with a zyxel 623 modem (bridged) for the last 48 hours and I keep getting my modem disconnecting and then it will not let the router re-connect again.

    this results in me having to manually hard-reboot the modem and sometimes the router as well.

    i've managed to set up wallwatcher to log everything that happens on the router, but i don't know what do enable/disable in the logging to find out the cause and stop it happening.

    i've tried both the keep alive and connect on demand settings and itkeeps happening. i've tried stimulating traffic with torrents, or leaving it idle.

    i had the modem running solo with a single wired connection for weeks without problems, so i'm petty certain it's not that. i even re-connected it with a factory reset and it still worked okay again on it's own.

    i have 2 wireless clients (xp pro) and one wired kiss dp-1500 divx dvd player connected to the wrt, but it still happens with only one connected client too.

    all hardware and software is up to date with latest drivers/firmware/patches etc.

    help me thibor, you're my only hope! (cue star wars music).

    i run my connection with an identical connection type as yours. the only time i see frequent disconnections are when my isp are di**ing around with my connection. there was a disconnect issue with a much earlier version, but is completely stable now. you mentioned a single wired connection ran okay for weeks; am i correct in assuming that the dial up was performed on the pc?
    did you run the pc permanently 24/7 without reboots and checking connection times?
    if not, it's not really a fair comparison as the router runs permanently.

    thanks for the reply thibor.

    before i got my wrt54gs i just used my dsl modem on it's own. it's a zyxel 623, and has a usb and an ethernet connection on it.

    the dialling etc. is all handled on the zyxel itself. there's no dialling done on the pc at all it just gets the ethernet connection from the modem and treats it like a normal LAN.

    i'm thinking that maybe it's torrent related as i've been purposely testing it with no torrents running and it's been up for almost 24 hours now, the longest since i got it.

    gonna kick off a few torrents now and see what happens. (XP Pro SP2, Latest Azereus).

    actully, quick question. my laptop wifi connection has QoS listed in the network properties, but my desktop (with wifi pci card) doesn't have it for some reason. i tried adding it in, but there wasn't an option without a setup disk. i thought XP would be able to do that itself, but seemingly not. it's a WMP54G in the desktop BTW and the laptop uses a standard intel based 802.11b card, while I'm waiting for a G one to come from ebay, but it does the job for now.

    the reason i mention it is that the desktop is running the torrents and I have QoS set up on the router for http, pop set to high & skype set to highest, with the general bittorrent set to lowest and a specific setting of lowest for my bittorrent port on that PC. UPnP is also set up and works fine according to the Azereus msg's i get.

    if i have QoS set on the router, but the wifi connection on the desktop doesn't have it listed, would (or could) this be the cause of my woes?

    i've tried installinbg the wmp54g drivers from linksys but they just jam my system up, so i'm sticking with the xp drivers for now.

    thanks again

    if your modem is doing the dialling itself and your router is getting a public ip address passed automatically to it, this is called "half-bridge", it explains why i got confused. drivers are a frequent cause of headaches with wireless devices. also you said that all latest drivers/patches, etc are installed; which isn't strictly true is it? you should stop all torrents and perform an accurate speedtest on your connection and then set the upload value in QoS.asp to 85%(roughly) of that value. this will leave enough headroom for other connections to not get swamped. if your wifi cards don't have qos, turn off "Wireless QoS" on the router. it's not needed.

    if i turn off the wireless qos on the router, will it cause torrents to slow everything else down?

    newest drivers = everything except the wmp54g. :)

    would my best bet be to get wireless QoS working on the desktop? the laptop is using it already, so I can only imagine getting the desktop one working would be the ideal solution, rather than turning it off completely. we use skype for calls on the laptop so it might well cause problems if the desktop is running torrents at the same time.

    the connection is 3072/384 (theoretically) but I haven't tested it fully yet on any speed sites. I'll do that tonight anyway when I get in.

    is there a better way to have the modem and router configured to work together?

    it would be nice if there were a way to access both the modem config and the wrt config at the same time, but I've not been able to get that set up.

    I was contemplating getting a linksys dsl modem i'd seen on ebay but i'm not sure if it would be any better.

    thanks again for your help anyway.

    wireless qos is to prioritize video streaming apps, etc. it won't slow everything down. you should be concerned with getting qos configured correctly on your router, not the desktop. i have my modem set in bridge mode, and my router does pppoe to establish the connection. i personally find this is the best method, as i prefer the wrt to control as much as possible.

    yeah, that's the way i have it set.

    interestingly enough, I changed back to connect on demand with an idle time of 5 mins and this time it seems to be running much better.

    even tho i have a disconnection (i'm guessing an idle timeout) my uptime is almost 24 hours now, and it reconnected fine.

    seems better anyway.

    thanks again.

    just one last thing. is it possible to configure the linksys with a different length WEP key than 64 or 128 bit?

    i have a kiss dp-1500 divx dvd player and it doesn't seem to like anything other than 48 or 109 bit keys for some reason (according to another forum) and the only alternative is either ethernet or no encryption at all, with neither being a practical solution.

    not possible that i know of

    meh, nevermind.

    so with no encryption the only thing i can do is mac filtering and restricting the no. of connections to what i have myself?

    or is there something else i could do?

    i suppose i could turn down the signal strength and put a reflector behind it to direct the signal away from the road.

    still not ideal tho. :(
