I have a v4.0 wrt54g and I was wondering if there are any stable firmwares available for it? Im using v4.20.6 - HyperWRT 2.1b1 (Rupan), Jul. 21, 2005 - but Ive been getting quite a few disconnects lately. If I wanted to flash back to a factory firmware, which one should I use since on linksys's site there is no mention of a v4.0 router at all (they only go up to 3.1 I believe)? Ive tried searching around on these forums, but I havent found any difinitive solutions - I'd appriciate any help I can get. Thanks!
