Sitting in my hotel lobby in Mexico I was surfing away on my MacBook when I noticed a lady sitting across from me looking increasingly frustrated trying to work on her HP laptop so I offered to help her out.
She explained that Windows Vista simply refused to connect properly to any of the three wireless routers that were available here. I knew they were working at least to some degree as my MacBook and iPhone were connected.
It turns out that the problem is caused by a combination of things; firstly some routers don’t comply to the wireless standards 100% as they should be and secondly Windows trys to auto-tune the connection so that it can utilize bandwidth.
It is this combination of factors that is causing the connections to drop almost immediately after authentication.
If this is happening you will probably be able to authenticate with the WEP or WPA password required and you may get an IP Address also but internet connectivity will never actually be established.
Full instructions on solving this below.
