I have a strange problem.
If I boot into windows (7) using Bootcamp, then the next time I boot into OSX (Snow Leopard) Airport cannot connect to my wireless network. It can see the network but with a low signal strength (2 bars). Connection fails with a timeout error.
If I boot back into Windows, the wireless works again.
I haven't figured out why, but after a few dozen reboots between windows and OSX, Airport will finally connect to the wireless network and the signal strength is back to full (all bars full).
This is definitely not an environmental issue. The wireless is lost as soon as I boot back into OSX from Windows, and it still works when I boot back into Windows. So there is no interference or anything. I have had solid signal strength for a year or so with no connection problems. This first happened when I booted into Windows 7 after installing it. My iPhone works, as well as the 2 other machines in the house.
I filed a bug report with Apple but I think it's just going to be marked "cannot reproduce" and forgotten. I have also completely trashed all the system network settings and set things up again, to no avail.
I have a Netgear DG834GB. I cannot see any sort of security/firewall messages. I did actually find one single thread on a forum somewhere where somebody else had this exact problem, but I have lost the link. But there was no solution anyway.
So, has anybody got any suggestions?
