High wifi latency when running on battery

Hi,

I installed Arch Linux on a Macbook Pro, the wireless card is functional and I'm able to connect to any wifi.

Problem: the network is slower when running the computer on battery only.

Example:
on power source
ping roundtrip (google.com): 30ms

on battery
ping roundtrip (google.com): 300-800ms

Additional info
Macbook Pro 5,2
Broadcom BCM4322
wicd for wifi management

Can anybody help me pinpoint the problem ?

Thanks

Re: High wifi latency when running on battery

I finally got it working by following the instructions on https://wiki.archlinux.org/index.php/Wicd.

I'm not sure which component solved the problem, but it is one of those:
* installing hal
* add user to group "network"
* remove interfaces from rc.conf (!eth0 ...)
* remove "network" from DAEMONS
