i am currently using a Sony VAIO, Vista business edition.
I noticed that whenever I lock by laptop, the wireless connection will drop
after sometime. I will need to re-establish the connection when i login to
the computer again. Another of my colleague has the same problem.
Has anyone encounter the same problem, is there a resolution to it?
