Windows 7: Unable to change wifi password in windows 7

Unable to change wifi password in windows 7

Hey all,

I recently changed the SSID and wep key (10 digit - passphrase generated) on my router (Linksys WAG54 v3. Firmware 1.00.65). All computers on the network have been updated successfully and are accessing the internet, except one.
It's a new Viao laptop, running Windows 7 Ultimate 32-bit. It's been working fine, able to access the internet on this router, until I changed the SSID and password. Now whenever I try to connect, it only gives limited access.
The password has been triple checked.
Router has been reset multiple times.
I've disabled, re-enabled, repaired and even uninstalled and reinstalled the wireless card.
All settings on the laptop have been cross-checked with other computers on the network, and it all matches exactly.
The laptop isn't receiving any packets from the router, and the router hasn't assigned an IP address or SSID to the laptop, indicating an authentication issue.
This is supported by network diagnostics, asking me to check the wep key, which I've obviously done many times.
On the router side, all other computers are having no problems, there are no restriction policies set up. I've released all clients and re-checked lease times and maximum allowable connections. Everything is 100% working for the other computers
I'm thinking this is a registry bug, as my girlfriend may have entered the Wep key incorrectly the first time, but I'm fresh out of ideas and haven't found any similar problem on the forums. Any help would be appreciated.

Thanks

Can't you just log into the router and reset the settings?

If you don't have the password, you can perform a "hard" reset using the reset button on the back of the router, normally you need to hold this button down for up to 30 seconds.

Won't reset the SSID and password as well? It is just one computer having the problem. Others on his net are fine.

done a hard reset. Resetting the password back to the old settings won't have any effect. I removed all networks from the wifi list on the laptop, which should in effect remove all stored keys

some extra info: on the DHCP routing table on the router, all other computers show up except for the one in question.
On the connected wireless clients list, I can see the MAC address for the computer in question, however the router cannot detect the SSID or computer name, so I'm pretty sure it's an authentication issue, but why is the router not accepting the Wep key rom this computer only?

Have you tried deleting your network profile from "Manage Wireless Networks" in the Network and Sharing Center and then reconnecting to your wireless network?

Of course. Have tried all standard solutions. network profile has been removed. Wifi adapter uninstalled and reinstalled. wireless networks removed and re-detected. Network diagnostics run. As I mentioned before (I think..) the result of diagnostics is it suggests I have the wrong key. of course I have triple checked and I am definitely entering the correct key

I've also tried many router based solutions. Changed the frequency channel etc in case it's interference. Doesn't make any difference.

It would be helpful if you could post a screen shot of your ipconfig from the Vaio, you will need to type ipconfig then "enter" into your command prompt then post the screen shot here.
