I read in forum that it was possible to upgrade a WRT54GL to WRT54GS - but I can find the post anymore. I have Belkin WIFI card supporting Speedboaster and would like to get higher transfer rate to my file server connected to the Linksys via network cable. I am currently running HyperWRT G Thibor15c. I therefore wonder if anyone could point me to a post for for upgrading a GL to GS - or give me any good advices regarding this matter. Thanks.
