    I've tried numerous methods trying to get my wrt54g v4 to work consistently but I can't stay connected for more than 5-10 minutes, (WIRED or WIRELESS!) without my Comcast RCA modem and router coming to a complete stop. I purchased this router last week thinking it would be an easy switch from my old reliable linksys BEFSR41 but the last few days have been frustrating to say the least.

    I initially upgraded the linksys firmware to 4.20.7 hoping that would solve the problem. Of course it didn't so I flashed dd-wrt.v23 mini and disabled STP for comcast. The router still comes to a complete stop after a few minutes browsing the internet and I have to go through a restart of the modem and router to get back up. Switching back to the BEF eliminates any issues so I know both are rock solid as always.

    I've talked numerous times Linksys with no luck. The last suuport person suggested I had a synch problem between the 54g and the RCA and suggested I take the 54g back and buy a different brand of linksys router. I'm not ready to give up yet and I'm looking for suggestions on what I should change or try now that I have the dd-wrt installed.

    Here is my basic setup:

    Comcast RCA DCM225 modem

    Dell Inspiron 600M, XP/SP2, Centrino 2200BG (updated driver) managed by PROSet, not Windows. Broadcom 440x nic and use Dell port replicator when wired (have undocked with same issues). I have two other wired laptops I want to connect after establishing consistent wired uptime with the Dell.

    WRT54G v4 with DD-WRTv23 mini firmware with default settings with the exception of STP disabled for comcast.

    ANY suggestions or help would be greatly appreciated before I give up on this router and look for other options!

    That RCA modem --- is it several years old? Comcast is now replacing those with Motorolla modems. I had a TON of issues with the RCA, so comcast replaced it.
