Wifi Power on Battery

Hi all,

I'm having issues with my wifi using 10.10 64bit whilst on battery. In windows on the same machine, i am able to get satisfactory performance from my wifi whilst on battery, but when in Ubuntu on battery, the performance is hopeless. It works much better whilst plugged in, even though it still isnt as good as it is in Windows. I do believe that i disabled gnome wifi power saving, but this didnt help. Even my 5 year old acer offers better performance!

I have install drivers as suggested by ubuntu (Broadcom STA).

Thanks in advance,


Hamish
