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!
