Since I installed Ubuntu 12.04 (fresh, not upgrade), my wifi is much weaker than before and much weaker than under Windows XP. It doesn't establish a connection unless I carry the notebook directly to the hotspot. (Side note: I remember my 9.04 had stronger wifi than XP).
My wireless interface is
wlan0 and with
sudo lspci -nn I found that my network controller is:
Network controller : Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4222] (rev 02)
Should I report it as a bug?
Is there a configuration how I can improve it?
