The client can’t access the internet. For troubleshooting, we ask her to ping default gateway, for example, ping 192.168.1.254. She gets general failure. What we have done:
1. run netsh to enable autoconfig,
Restart the computer.
2. Run netsh to delete arp, for example
Restart the computer
3. Run netsh reset, for example
Restart the computer
4. Run admin command prompt, run DISM/SFC:dism.exe /online /cleanup-image /restorehealth
then
SFC /SCANNOW
Restart the computer.
5. Try to disable it by running this command;
netsh int ipv6 isatap set state disabled
netsh int ipv6 6to4 set state disabled
netsh interface teredo set state disable
6. Reset winsock
netsh i i r r
netsh winsock reset
Then reboot.
7. Run safe mode with network.
8. Try to disable the firewall or security software for a test.
9. Run network troubleshooting on Windows 10
10. Try another wifi USB adapter. It receives the good IP address, 192.168.1.163, DG 192.168.1.254. Still, can't ping 192.168.1.254.
Any other suggestion?
