Windows 8 - Won't accept correct network security key

[Peter.Steele]

So I've got a new Windows 8 tablet. I like it, except for one minor detail: it won't connect to my network.

When I brought it home, it connected just fine, but I rebooted for some reason, and after that ... it won't accept my password. It just keeps telling me that the network security key is incorrect. I've got absolutely the right password, no question about that, but no joy.

I've rebooted. I've turned wireless off and back on. I've rebooted the router. I've updated the router firmware. I've done every damn thing I can think of, but it just keeps telling me that the network security key isn't correct.

Anyone got any ideas?

Wow, this one is a classic. Thought that windows got rid of that problem.

Ran into it in 7 now and then. It was some kind of bugged cache for the wireless connection. In the worst cases no kind of deleting the connection would restore function.. we just imaged the damned things. Likely the bug resided in the registry somewhere.. a ghost connection.

Try clearing the connection as deeply as possible and re-add. Should fix.

Is the power on? Did you make sure that the wireless connection was securely plugged in?

Delete the wifi connection on your wireless settings: Control Panel > Network and Internet > Manage Wireless Connection > Delete the wifi. Reboot your pc, try as well to reboot your router (if needed) and then connect back to it with correct password associated. Hope this helps. Good luck!

Make sure your speaking the same language WEP, WEP2, etc.

yeah forgot.. you need to fully restart the system after "cleaning" out the borked connection. For whatever reason the cached borked connection won't clear without a full restart. If you re-add it will just re-add the borked ghost connection.

Like I said, I though this issue was fixed in windows 8. Guess not.

Turn off CAPS LOCK! Don't laugh, it gets people every time.

Is the wireless controller setup for WPA2? If so, are you using the native Windows WPA supplicant? If so, are you sure the wireless controller supports NTLM hashes for MSCHAPv2?

If the controller doesn't support NTLM for MSCHAPv2, you'll have to set the client to use something other than MSCHAPv2, or modify the wireless controller to use something other than WPA (less than ideal).

Heh. Is your AP too old to support multiple devices? I found that an AP that I was using only let the FIRST person on when they connected to it. We had to fight over who used the wifi...

So now when I buy a WIFI device I look and make sure that it will support MULTIPLE devices at once...

[Peter.Steele]

Well, I no idea what happened, but after I rebooted 5 or 6 more times, it accepted my password finally. No idea why or what happened, but there you have it.

Incidentally, the router is a Netgear WNDR-4500v2. It's a dual band N900 router, so there's no issues with number of devices.

Like I said, no idea how or why it works now and it didn't work before. Password is the same.

Create a windows system restore point every couple days. Sometimes this time machine built into windows will solve problems by going back to when everything worked fine.
