I have a wrt54gs v2 linksys router and after downloading the v4.71.1 hyperwrt 2.1b1+thihbor 15b1 firmw are my speedbooster no longer works and causes strange signal flucuations. I turned off the speedboster and now everything works fine. I did notice a feature in the router's web page on the WirelessTab>Advanced Wireless setting>Afterburner is checked. I don't know what this setting if for but perhaps it and speedbooster don't work well together. Anyway, if someone knows why speedbooster isn't working I would appriciate the information. Otherwise, Thihbor I deepley appricate your efforts and have for many years, appsolutely great work, thank you!
