Public bug reported:
I am using ubuntu (i386) since 6.06 on my acer asprie 5610 laptop.
Wlan always worked fine on it but since ubuntu 8.04 and probably the new
networkmanager it's a big problem.
Today I am using ubuntu 8.10 with all latest updates.
When wlan is activated and in use there are four very serious problems:
1. When there is no input from me via mouse/touchpad/keyboard the whole system
is getting mostly slower and even sometimes pauses (even a simple ping pauses)
2. After about a few hours uptime the kernel panics - numpad blinking
3. Wlan is significant slower (even a simple ping) then on windows or on other
notebooks with also 802.11g
4. Wlan is significant unstable compared to windows or other notebooks
