Hi,
I am using ubuntu 11.04 i386.

i can say that my modem's wireless broadcasting is excellent based on my experience on win 7, i do not remember whether if i install an ethernet driver or not.

but i did not install any ethernet driver but can connect the internet excellently with a wire to modem

the problem is that in ubuntu, my wireless connection is cutting off per minute, cuts off, then connects, cuts off then connects...

i must solve it because at work i can get connection by only wireless.

what should i do?
thanks
