Hi,

It used to work before, but suddenly laptop won't connect wirelessly to network.
Other computers can still connect wirelessly.
Nothing was changed on the router, modem, or laptop.

When I try to repair connection, it will keep trying to acquire a network address.
I tried winsockfix.exe, resetting using netsh winsock reset catalog, netsh int ip reset reset.log commands & rebooting, all to no avail.

Laptop can connect to the network if ethernet wire is plugged.
Laptop can still connect wirelessly to other networks.

Thanks for your help!!!

Do you have any errors in Device Manager, especially regarding wireless network adapter?
Did you try to reinstall its driver?

No errors in Device Manager. I didn't reinstall as I don't have the driver, but I'll try to update drivers from Lenovo. IMHO driver might not be the problem because the wireless works on other networks? Thanks.

What networks would that be?

A couple thoughts - have you reset the router? I don't mean factory default, just power off/power on.

If you know how to locate the MAC address, see if the DHCP provider (usually the router) has that address as still leased. If so, you will need to release it and power cycle the router. I would leave it off for a minute or so.

If it turns out to be the router, make sure it's not overheating. Dustblast it, make sure it's not on a heating element, etc.

Wireless capability still works on other SSIDs such as at home or one of my other workplace.
I don't remember the router being powered off/on after the issue. Ok I'll try this one out. Thanks.
