Hi everyone,

I'm having an issue with the wifi on my Macbook Pro (17" 2009 model).

Other computers on the network, including a new 13" Macbook Air are hitting speeds of about 47mbps. The Macbook Pro however, is only hitting 20-21mbps in the same location.

I'm using a Time Capsule (original model) as the router.

Can anyone think what might be causing this? As I say, the Macbook Air is working fine, and both use 802.11n. It's just the Pro is significantly slower.

Thanks in advance.
