Not Getting Speeds I am Paying For
I have been getting a constant 20 mb/s over my ethernet cable even though I am paying for 600 mb/s. I have xfinity's provided modem: Voice and Data Modem ARRIS GROUP, INC. TG3482G
Just looking for any suggestions on how to fix this? I was thinking about getting my own router/modem but I would prefer to not have too.
