For the last 2 or 3 weeks every time I try to connect wirelessly (not sure that’s a word) I have to diagnose my connection and then reset the network adaptor and everything then works fine, I'm sure it has only occured after a windows update but its beginning to do my head in as I often swap between home, work and friends wireless. I have checked all the authentication keys etc are correct and as I said as soon as I reset the network adaptor its fine. I'm running Vista home premium on a Medion laptop, any pointers would be appreciated.
