I flashed WRT54GS router with HyperWRT 2.1b1. Everything worked great UNTIL I needed to login to the Linksys Parental Control managment web site and change some settings. The Linksys managment site insisted that there was NO ACCOUNT with my user name and password. I reflashed the router with stock Linksys 4.70.6 firmware and was immediately able to login to the Linksys Parental Control managment web site. Loved the features HyperWRT added. However, it appears that, at least for now, if you use the Linksys Parental Control feature, everytime you need to change a setting you will have to re-flash to standard Linksys firmware. Anyone else using Linksys Parental Control and having problems logging in using firmware other than stock Linksys versions?
