Can't Ping Network Devices

[markaz]

Until last week when I would map our home network my PC, laptop and TV would all display and I had access to shared folders. I changed wireless security settings last week from WEP to WPA2-PSK. Now when I map the network nothing shows except the computer being used. I've tried pinging IP addresses and computer names and get the same message with each attempt: "Destination host unreachable". Here's the kicker....I can access the internet just fine on both computers and can watch movies via the Firestick.

Yes, the devices work just fine for their primary purposes, but I can no longer access shared folders on the network. Any ideas would be most welcomed. Thanks in advance.

If you run this onboth pcs can it see them NetBScanner - NetBIOS scanner.

Did you change anything else on the router there is a setting user isolation or simliar that block local access from wireless so if someone breaks in they can use the net but not access your pcs if thats on it would stop you seeing othe rpcs
