I'd like to know how to setup my fios router to authenticate using my radius server. I don't see the option within the wireless settings
I don't think the rotuer supports that option.
I beleive it just uses SSID and passwords.
As CRobGauth said, I'm pretty sure the Verizon routers don't support this option.
Do you have TV service? If you don't I'd strongly reccomend replacing your Verizon gateway with your own router capable of doing RADIUS authentication.
