Websites dont resolve using Fedora connected to an Xfinity wireless router

When using Fedora, websites are not resolving when connected to Xfinity Wireless Router. It is able to get an IP, but is not able to reach any websites.

Other devices: Windows, Android, and Apple had no issue with it.

• The Router Model: Arris TG862G/CT
• Security Mode: WPA/WPA2-PSK (TKIP/AES)

I tried rebooting the router, resetting the WiFi module, and resetting to Default configuration. I also tried manually configuring /etc/resolv.conf, checking firewall settings, turning off IPV6, editing nsswitch.conf. This all didn't work.

In this Comcast Forum, dtoaiselli recommended changing the security mode to WPA-PSK (TKIP). After changing this setting and restarting Networking, I was able to browse to websites again. Setting it to WPA2-PSK (AES), WPA2-PSK (TKIP/AES) didn't work either. But, setting it to WPA2-PSK (TKIP) worked, and I ended up keepiing it with this setting.
