A simple shell script that can automatically authenticate to XFINITY networks using the username and password supplied in the RADIUS config in Luci (OpenWRT ui).
This script is only tested for OpenWRT.
Two packages must be installed through opkg:
- curl
- wpad
Using Cloudflare or Google for DNS on the LAN interface is a must. Xfinity uses DNS requests to track that multiple devices are using the same wifi connection. The hotspot will then force you to reauthenticate, which causes network interruptions.
In the Luci UI, you can find this setting in Interfaces -> LAN -> Use custom DNS servers.
Enter your preferred provider DNS IP addresses there!
