I've a M2400, with win 7 ultimate.
For some reason everytime i try to connect to a wifi network, it never connects, including ones which I have previously connected to.
The only way i can fix it is to run the wizard to reset the connection and then it 7 times out of 10 will connect.
All of the drivers are up to date for the Intel nic & wifi
I'm debating unistalling the Dell Control point / connection manager software, just in case there is a conflict going on between control point and windows.
But has anyone else come across this issue?
