Thank you for responding to my plea for help! I do have a wireless signal and
the PC now has a wireless connection. I'll write out the steps I took before
it resolved, just in case it helps someone else out there searching for
answers, though I'm not sure which step was the right one.
Step 1: I turned off all of the Windows security features (firewall,
Defender, Secure User Accounts, etc.) just in case something wasn't allowing
an internet connection. I figured that once it was connected I could turn
them back on one at a time.
Step 2: I clicked Start, then Control Panel, then Network & Sharing Center,
then Manage Network Connections, then I right clicked on the Wireless
Connection, then clicked Properties, unchecked IPv6 and then clicked OK. Just
for good measure I went back and did the same thing for the Ethernet
Step 3: I had forgotten that for wireless security only MAC addresses are
filtered, so I didn't even need the IP address. I accessed our routerâ€™s
web-based setup page from another PC and entered the new PC's MAC address.
Then I went back to the new PC, clicked Start, Connect To, double clicked on
our wireless network, re-entered the passcode and other information for our
network and it finally connected!
