Wireless Connection Delay after Resume

[hunterman223]

I have been having this issue with my T400 with the intel 5300 card for quite a while. After resuming from suspend or hibernate, wireless status icon in the task tray indicates I am connected, but I cannot access the network or the internet. About 10 seconds later, it shows I am disconnected. Another 10 seconds later, it says "connecting" and a few seconds later it connects. Really annoying when I'm in a hurry.

This happens in Windows 7 and 8, with all drivers I have tried so far. I have used the standard windows ones, lenovo ones, and the newer intel ones.

Is anyone else having this issue, or could someone try and point me in the right direction?
