Hi,
i hope someone can help me finding a solution for the problem I have to deal with since I have updated my bios.
Ubuntu 12.04 (Server)
xfce Desktop
Problem:
I upgraded my bios. After the upgrade my networkspeed has slowed down to 50kb. Sometimes a bit more but never more then ~130kb. Sometime under 50kb.
Which biossettings can result in a slow network?
If i restart my router network speed raises up to 700kb for about 45 seconds minute and slows down again.
I tried downgrading my bios back to the previous version but this does`nt solved the problem and I upgraded it again.
