    Ahoy there,

    I'm using the Tomato Firmware 1.07 on a Linksys WRT54GS Router. Connection type to the Internets is PPPoE and everything worked really well for some weeks - until today. When I got home the internet connection was down and didn't came up again. The log says "WAN down, redialing..." over and over again, but the router is unable to actually establish a connection. I tried resetting the Router and the Modem, but this didn't changed anything. I'm pretty sure the router is the problem because plugging the modem into my computer directly works without any issues.

    Does anyone have an idea what could be wrong? Any help is appreciated.

    is external IP getting configured (by dhcp)?
    if not you can try setting it to static IP set the external IP by hand
    Save, Reboot and switch to PPPoE again it should work I had this problem a couple of times.

    Unfortunately the external IP is dynamically assigned via DHCP. Thanks for the hint anyway :)

    Did you have to use a PPPOE client when connecting directly to modem? If not maybe the modem has dropped out of PPPOE bridge mode?

    Yep, I had to use a PPPoE client. Also I doubt the Modem supports anything but PPPoE at all.

    Hmm, suddenly it started working again (without me changing anything). This is really weird.

    Thank you roadkill and mstombs for your help. If this happens again I'll try enabling "DHCP Reduce Packet Size".

    It sounds like your ISP had some problems.
