I'm not suggesting it's your modem, but the approved TP-LINK modems on the Cox list are DOCSIS 3.0.
Yup; I checked the approved list a few years ago. I have a 7610, and it looks like it's still approved.
Yes, it'll still work but I tripped on "newish."
As Mouth suggested, snoop along your coaxial cable for a splitter. A splitter is just a connection device, piece of hardware. Also check behind your wall plate for splitters. You may just have to replace it. Cheaper than a tech if it fixes.
Oh, I know what a splitter is; I just didn't realize you were both talking about in-house wiring. I can take a look at that after some meetings today and report back later.
(also, thanks!)
Sorry about describing a splitter. Yeah, in-house stuff to check before calling a $$$ tech. If it's an outside problem, you shouldn't have to pay for a Cox problem. Most problematic are splitters and perhaps older or damaged cable. This stuff you can replace yourself. If you read real close on your cable, you'll find a specification, such as RG-59, RG-6, etc.
