I have been trying to resolve this "acquiring network address" issues for about a week. Computer successfully logs onto a couple of networks but not at one site where I have three other laptops and a wifi phone connected.

Tried just about everything I could find on the net but nothing worked . . . . . . well I just solved it and as embarressing as it is I thought I would share the solution with you all.

Capitalisation - yep the WPA code as written down used capital letters and numbers but the entry needed to be in lower case - an error in transcription during the last reset and I just kept on keying it in as written down.

All I can say is sometimes you need to think a little laterally and go back to first principles.

Cheers
