I'm using Ubuntu 10.10 and i like it. But since yesterday i have a problem with the downloadspeed via my router. The normal speed is over 10MBit/s and i reached this speed always with Ubuntu. Since yesterday is have less than 1MBit/s. The Windows PC in the same wifi network still reaches over 10Mbit/s.
Don't know what happened to my Ubuntu installation. Anyone can give me some help to fix the problem?
i tried to install ndiswrapper but it didn't work with the original windows driver from the manufacturer of my wlancard. then i deinstalled. now at the moment the state is that ubuntu doesn't recognize the wlan card since it has deleted the standart driver when i activated ndiswrapper. I need an advice to activate the original driver (sudo modprobe wl doesn't work, Fatal: module wl not found)
now i managed to reload the original driver via modprobe wifimodulename Wifi works again.
changed issue: I now use the backport wireless drivers and i have the full wifi speed now again but sometimes after a time i use the wifi connection the speed again decreases to under 1MBit or even more bad to under 0.1MBit. When i deactivate Wifi connections via network-manager-applet and reactivate it, it again has the full speed.
