Slow wifi on MacBook Pro when connected to Thunderbolt Display
Hello everyone,
I've had my MacBook pro (2012) for about a year now, and I bought the Thunderbold Display last christmas.
Everything has been working fine until a few days ago, when I realised that my wifi connection speed was very very low (less than 0.5 mb or even no connection) whilst my other devices like iPhone and Windows pc were doing fine on 10mb.
I tried changing the router channel options but it wouldn't work. Then I disconnected the MacBook from the TB and wifi speed went up immediately...
Consequently I'm guessing it's the TB's fault. Can anyone help me find a solution? Or if i should bring it back for repair? (btw it's slow both with lid open or closed)
Thank you!
MacBook Pro, Mac OS X (10.7.5)
