I have a laptop that has ubunto Linux running on it. The laptop is connected to an Actiontech DSL router via Ethernet port. All the applications run fine (ping with various packet sizes upto 1464 bytes, ftp-ing larger file etc). But when I launch firefox it would only download text. The graphics would not load up. An interesting thing is that when I connect another laptop that is running XP to the same port on Actiontech, everything works fine including firefox. I was thinking of upgrading the firmware on the Actiontech to resolve the issue. Any suggestions?
