Broadcom 4313 Signal strength very low on an HP Pavilion dv4
I installed fresh Ubuntu 11.04 and i have wireless connection but i have to be very close to the router to have signal. I looked everywhere i can't manage to find a solution.
In my grub it says that i have :
3.1.4-030104 generic
old ones :
3.0.0-14 generic
3.0.0-12 generic
kernels.
I tried the solution here but i think this is for older versions of Ubuntu. On Windows 7 the wireless card is working flawlessly. Please help me to find a solution I'll be grateful.
