Strange Wireless Problem...

Hi,

I have a dual boot laptop ( HP i7 based ) It boots Fedora 18 and Win 7.

The problem is that the wireless on the Fedora side only connects at
one megabit, but on the Win 7 side I get a consistent 140 megabits.

The wireless hardware is the Intel Centrino Wireless-N 2230 bgn combo
blue tooth/ wireless card.

I have the iwlwifi-2030-6.ucode firmware installed in /usr/lib/firmware/

Is there anything I can check?

Any one else have this problem?

Thanks,

Jerry
