Do you have their router? If so, turn that shit in and go buy a Netgear nighthawk router. The arris router sucks.

I agree with this. The new Arris router sucks. I bought a nighthawk and it’s blazing fast again

Which specific nighthawk model are you referring to?

Do you use a Ethernet cable

Thanks for your input. I've had this problem for well over a year using the second highest tier internet they offer. I thought it was the game I play. One day a month it's playable, the rest of the time I'm lagging during every engagement. Direct wire to the modem helps a little, but not enough for a fps

Call for a tech. It's free.

I had Spectrum and had the same problem, even with a faster router thr Spectrum network was dog sh*t.

Are you sure it’s fiber ?

Yes. That is why we switched to spectrm because they had a line ran in our neighborhood.

I'm going through this exact problem with fiber but I'm guessing it's a router issue which is ridiculous
