Hello,

the wireless network connection of my HP 650 notebook is very unstable. I'm using Ubuntu 12.10 but the network was unstable as well with 12.04 (and even with the preinstalled SUSE Linux Enterprise 11).

Here's some useful information about my system (I hope):
Code:
nm-tool

NetworkManager Tool

State: connected (global)

I followed the instructions of this tutorial (http://michael-peeters.blogspot.de/2...er-ubuntu.html) until I get some problems at step 5 (dowloaded the drive here: http://www.ralinktech.com/en/04_supp...se.php?sn=5018).

ERROR: Module rt2860sta does not exist in /proc/modules
I don't understand why this error in the last line occures:

Code:
test@test-HP-650-Notebook-PC:~/Downloads/2010_07_16_RT2860_Linux_STA_v2.4.0.0$ sudo rmmod rt2860sta
ERROR: Module rt2860sta does not exist in /proc/modules
Has anybody an idea what to do? I really need to get the wireless connection running.

Thanks for your suggestions in advance!
