So I got a new work computer running Windows 7 Home Premium with an internal wireless adapter.... and I already got major problems.
On the first day of use, it easily found my office's wireless network (landlord's network, not mine). I put in the password and it connected flawlessly. During the rest of the day, I did a Java update and a Windows 7 update. That was it.
The next day, it would not connect to the wireless network. It says "Network Security Key Mismatch." I am absolutely positive the password is correct, but it will not connect no matter how many times I try.
I have disabled the firewall software--no effect. I have tried connecting manually, and it won't work. I checked the Device Manager, and there are no problems with the wireless card. The wireless card driver is fully up to date. Windows is up to date. I can see the wireless network, it has excellent signal strength, yet I can't connect to it. I can connect to it thru the wired connection, but not wireless. The Dell rep had me do a system restore, resetting everything back to factory specs, and it still won't connect.
I researched the issue and found many theads on it going back two years now, yet nothing seems to solve it. There is a blizzard of people using technical terms and cryptic abreviations that are way above me.
If any of you have suggestions, I would be forever greatful.
If you can fix it, I will Paypal you some money.
