Hi there, i got a wrt54gs from a friend with Firmware Version: v3.37.2 - HyperWRT 2.0 on it. it works fine wired as wireless to surf the inet but e.g. since a week i canÂ´t download any files which are bigger than 1MB Uploading files via FTP and DYNDNS doesnÂ´t work too. User see their root directory, but as soon as files are transferred the bandwidth goes down to zero. Without the router everything works fine. Now i wanted to update the firmware to the original Linksys firmware, but everything i receive is a screen with the notice "Upgrade are failed". So with every other firmware Is it possible at all to change the firmware? Or must i do this:Crashed ? thanks for every answer!
