I’ve been using 3rd party firmware, dd-wrt for my Cisco’s Linksys WRT54G v5.0 around a year. Somehow, it gave me a lot of disconnection and instability. The latest dd-wrt firmware that I used is dd-wrt.v23_sp2_standard.
I made a decision to revert to the original / official firmware version 1.02.5 from Linksys.
Below is the details.

Hi, i’m in the same situation as u do. Using dd-wrt v23 sp2 on wrt54g v5.0. A lot of disconnectivity and instability. Do you mind telling me how has the router been doing since you reverted it back to linksys firmware?
FYI, reverting back to original firmware is a savior. Since then, I never felt any downtime. Hail Linksys firmware!

Hey I have been trying to revert my firmware as well but it keeps failing when i try and load the linksys firmware
John,
The WRT54G V5/5.1/6 do not support direct reversion from DD-WRT to Linksys firmware. Please see http://www.bitsum.com/openwiking/owbase/ow.asp?WRT54G5_CFE. Apparently replacing stock firmware with DD-WRT firmware on WRT54GS V5/5.1/6 routers is a one-way street. There is an exception–you can essentially revert your WRT54GS with DD-WRT to a stock WRT54G.
k thx bai,
Ron
can you tell me what the procedure is for restoring the linksys firmware? i have downloaded the latest linksys firmware, but it can’t be uploaded via the dd-wrt interface. i assume i’ll have to use tftp, but the vxworks bootloader was overwritten when i did the dd-wrt upgrade, so i don’t know what to do at this point. even though linksys firmware sucks, the dd-wrt firmware was a huge mistake.
ps – my router is a WRT54g v6
Man I’m glad I read these post before I flashed my router!! I think I’ll stick with the linksys firmware. Thank for the R/D info.
If people actually read the faq at the dd-wrt site they would realize that V5 V6 is not supported by the DD-WRT firmware, due to the fact that there is not enough memory on those devices.
The WRT54GS I have is directly supported and has enough memory. It is a v6 linksys running v24 SP1 and has had nothing but WAN connection issues – everything else works great and plenty of free memory to operate.
I’ve done alot of reading on this issue and it seems to be quite widespread. I think I’m going to do some reading on how to revert back to generic linksys software because it’s hardly usable with the DD-WRT firmware on it.
