Purchased a TP Links AX6000 and the modem starting having issue. Called cable company and they denied issue. Logged is as said and it did reflect some potential cable issues. However in an attempt to have reliable service during the week timeframe for them to show up I reinstalled my Netgear Nighthawk AC2300 and the modem returned to working properly. During the time the TP Links was in service I did make sure all components had the latest firmware updates. How is a router making a modem look like it is losing the cable input? Also the router worked flawlessly when connected directly to a computer. I have read multilple posts on boards about all brands of WiFi 6 routers causing this modem issues. Sending the AX6000 back but I do want to upgrade to WiFi 6 but sounds like this modem is unable to handle it. Will this get corrected?

I personally would avoid anything TP-Link. I recommend you try this, get on amazon and find a NG model RAX router, try a RAX80. Amazon has good return policies and usually you have 30 days to try something out. Give a RAX a try with your CM1000. Be sure the modem signals are Good. Besure to use CAT6 LAN cabling between the modem and router and router to wired devices. I would first test the RAX out with what ever FW was loaded on it first, or you can load latest FW. Try something out and see how it goes. Another consideration is that do you need AX at this time? Can you fully take advantage of AX? Would a AC class router suffice as well?

Not sure where your hearing this issue. ANY wifi router should work with any modem. cable or otherwise.

Couple of factors are signal from ISP service to modem needs to be checked.
Be sure to use good quality RG6 coax cabling.
Be sure that no coax cable line splitters are in use.

Other problems may stem from faulty wifi routers or bad configurations of the routers.

The CM1000 is capable of handling 1Gb ISP services. My CM1100 and Orbi AX works fine on a 1Gb service.

  On these boards had similar issues. I was looking at both the Netgear and Linksys as the replacement for the TP Link AX6000 but I see they also cause issues. Reliability is a very real concern since I host many meetings from home. (see post discription below)

  New router issues with Netgear CM1000 modem.
  I have Cox internet with a Netgear CM1000 modem but have problems with all WiFi 6 routers I have tried and had to return them for locking up or dropping signals. I have tried both Netgear and Linksys. I also have a hub plugged in for extra wired devices. I have 300mbs service, Any ideas or has anyone else had similar problems? Cox says signal is great. I uses the latest firmware all all routers.
