I'm sorry about the issue. Please try the following fix:
- Disconnect the power cord(s) from your Internet modem / router device(s) for about 5 minutes, then reconnect, then wait a few minutes
, then shut down / restart the problematic computer, and see if you can connect it to your Wi-Fi / wireless network name and check.
1. If that does not work, on the problematic computer, open Control Panel, then open System and security / System, then click on Device Manager on the left.
; (Or press at the same time the two keys Windows and R on the keyboard, then type devmgmt.msc then click OK, then the Device Manager window should open.)
2. Then double-click on the item Network adapters in order to open / expand it
3, then right-click on each of the item(s) under Network adapters, then click on Uninstall, then click OK to confirm
4, then restart the computer, then wait a bit, then check Wi-Fi.
- Does it still say Wi-Fi doesn't have a valid IP configuration? When did this issue first occur?
