CM1000 modem with WiFi 6 routers
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...
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?
Spoke with NG support last night. Downloaded a firmwear HOT FIX for the router that I believe was for the NG router security issues but she said there was other updates. She did not know if it address this specifically so we are on a wait and see. It hasn't dropped, it has been about 12 hours of only mild evening usage. We will see how it responds today.
Ok, let us know.
That was not the silver bullet. Modem just dropped out and came back with the upstream, downstream and internet lights flashing. Same as piror. Without touching it the modem restores itself. This is exactly what was happening with the TP-Links AX6000. I will keep it on if it drops again I will call NG. However it usually is back up by the time I get through the hold period. Not satifactory since I will be hosting webex sessions tomorrow and this would not be acceptible. Without a concrete solution I will be putting the old router back in service. If the modem is bad that is not a good sign for NG since it is only about a year old.
I would find you another modem, either same model or a CM1100. Would need to check to see if a different modem does the same thing. I know my CM1100 works well with Wifi 6 routers. Tested a few. IF the different modem still has problems, it maybe ISP related. Something to check out. I would find one on Amazon which has good refund policies.
So while typing a reply the modem dropped out. I put the old AC router back in service. After work I will log onto the modem and get the error log.
If I have to purchase another modem that ups the cost for WiFi 6 and I will probably wait until I "need" WiFi 6 versus getting ahead of the curve. I would go a different direction than NetGear since I bought this modem (paid more than others) only a year ago and thought I would be getting something that would provide service into the future up to a Gig of service. (only at 250 now).
After working I will log onto the Modem, print the log, and put the RAX80 back in service. I'll call NG again and most likely waist another portion of my life on hold. I don't have a lot of confidence they will have a solution at this point.
I would try another modem to see if the problem continues with the RAX router. You can send it back once you test it out. I find it odd that the modem seem to exhibit this issue if a RAX router is conencted vs an AC only router.
I would definately keep in contact with NG support, and keep them looking in to this. It's got to be something they should be able to find.
Yeah it doesn't appear logical. The modem should be sending and recieving traffic from the router, regarless of the router. Could they be generating some sort of noise on the line that the modem is unable to handle? The errors when I had the TP-Links AX6000 on were
Missing BP Configuration setting TLV Type:17.9..................................................
SYNC Timing Snnchronization failur - Filed to acquire QAM/QPSK symbol timing; CM .................................................
No Ranging Response received-T3 Time-out CM-.........................................................................
I attached the modem error log from when the TP-link router was attached. Researching them would say bad cable but why does the AC2300 work? And I do get the speed I pay for plus often over my 250.
Any Ranging failsures is a ISP signal or modem issue. Routers shouldn't or wouldn't cause this.
LAN cable is important, even though one might work for one router, it might fail for another. CAT6 is recommended.
Would be interesting to see if a different modem work. Even an ISP provided one with the RAX.
Just to be clear the cable between the router and the modem matters? I did not use the cable that came with the Router but used the cable already attached to the modem. hmmm after work when I am back with the new Router installed I will use the cable that came with it.
Try that as well.
WOW worse than ever. Speed tested prior to taking the old router off 248 and checked tightness of all cable connections.
Disconnected the old router and connected this computer directly to the modem to get the error log (attached). I also looked at the cable connection and is says good and have the other screen I don't know what to do with it. (2nd attachement).
Shut everything down. Connected the RAX80 with the new cable. The modem would come up and almost as soon as the router was fully started the modem would crash out with all lights going amber then off and start flashing green as they restarted. Restarted everything three times but couldn't get it up and running. Put the old router back in place and immediately all is working well.

I would try a different modem, even temporarily. Keep in touch with NG support. Ask about an RMA as well.
Well it is over. Last night I spent a significant amount of time on the phone with Netgear. Thankfully the issue was happening during the call. Took all devices back to factory settings. It was working breifly when we hung up on a 24hr wait and see and I needed to call the ISP to redo the MAC Provissioning on the Modem. It didn't last a 1/2 hour. The ISP did the MAC Provisioning and they did all the resets and refreshes they could perform. With the RAX80 on the system the modem was crashing. I put the AC2300 (R7000P) back in service and the reliablity is restored. Hasn't dropped since I re-installed it about 11 hours ago. The modem is potenitally over a year old so i doubt they will do any returns. I fought the good fight and have gone way above and beyond a what a normal customer would do to attempt to get this working. Many hours of research, on the phone and actually logging into the various "plug and play" components of the network.
I really do appreciate your support during this and your replies. It was very helpful. Just sorry for the out come. The router is boxed up and ready to head back to Amazon.
Thank you and God Bless.
Good luck.
Just an update. For almost 2 weeks now, we have been back on the AC2300 and not even a blip. Been working fine. Was at a Best Buy and saw the Netgear WiFi 6 mesh router and the wife asked me if I'm crazy. Didn't buy it. Don't think it will work with this modem.
