Recently I signed up for a new internet and wifi provider, Xfinity. My house has several devices including 4 TVs, my laptop, and multiple cell phones and they ALL connect to Xfinity. BUT, my main I Mac computer will NOT connect. So I have also been paying for Century Link because I use this computer for work.

I have tried several things and now wonder if Firefox is permitting it to connect (according to my mobile app internet IS connecting to the computer).

Can someone help?
