Wifi not connecting Fedora 35 with Intel Centrino Ultimate-N 6300

hi i had same issue.
try adding DNS info manually, this worked for me on Fedora 35.
link to post here.
or you can try adding DNS info graphically by Settings->Wi-Fi and click Gear Icon on your WiFi name → Ipv4 and disable automatic DNS option.
enter the manual DNS as suggested in above post.
