    This is the best personal modem you could buy in the market right now. It beats the one that your cable provider provides to you. You won’t be disappointed.

    As advertised. I was getting 1.3Gbps on my desktop directly connected, (1200 mbps internet service). If/when upgraded, it will still fit perfectly. Only thing to look out for here, is if you are using a wifi router. If you do not have a second IP available, you won't be able to have the router AND your computer directly connected to this device. (Comcast was not so helpful here) Overall still recommend 10/10

    My ISP is Wave, replaced their awful modem with the ARRIS and started saving $20/month. Cutting over from the ISP was simple, turned right up.

    Simple, easy does the job. Only giving it 4 stars because of the light. I'm just used to seeing the specific indicators but this just has one in which you have to learn what the different colors mean.

    It's a pretty good modem. Not getting the full speeds advertised by my ISP but I think tha'ts more on the ISP's part than the modem. I like the new design vs the old Surfboard designs. More boxy, makes me think of the ps5
