I installed Ubuntu 11.10 64-bit yesterday and everything worked fine until I used my internet connection.
It's very unstable, sometimes it works fine but most of the time it takes forever for a website to load. Or when I'm on skype, I don't hear everything my friends say.
I have no problem at all on Windows 7 64-bit and my speed is about 20 times higher.
I already disabled IPv6, updated my Realtek drivers, changed the order in nsswitch.conf, changed the MTU value to 1492 and a few more things I don't remember.
Can someone help me to fix it, please?
