Win10 Reports C7000 has connection issues/problems
I bought my Nighthawk C7000 just over 2 years ago and have rarely had a problem, other than not getting very good WiFi range in an apartment with relatively thicker plaster and metal lathe walls. Just recently many of my Wifi devices that did connect were dropping. My PC was unable to connect to the any of the wired connections and thankfully I could connect using the wireless option. When I tried to troubleshoot the wired option I couldn't get reconnected. Rebooting didn't work, renewing the connection, turning everything off for at least a minute, disconnecting other connections, etc. I couldn't even get my phone to connect wirelessly at times.
I noticed that the device would also lose connection to the Internet so even if devices connected, there was no Internet. The provider was up and was fine (Spectrum.) Trying to use Win10 's network troubleshooter reported that the modem was having problems connecting to the Internet. This went on for a week and change intermittently. As of now, it seems things are back to normal but I have this fear it's going to happen again.
Question: Might this be signs that this relatively newer modem router might be starting to head its way out? Any internal tests that can be done to test ports, etc.? Any thoughts on what this could have been?
I've solved the problem and I will figure out the nature of keeping the extender/bridge assigned in the proper IP range.. On occasion I'd turn on an Asus Asus RT-AC88U router/extender set in extender mode to reach weak spots. It's a fantastic device and connected to the c7000 via ethernet. For some reason the c7000 began to assign it 192.168.1.1 (perhaps the extender reset) and , for reasons I cannot explain, the c7000 decided to occasionally provision wireless devices under the 192.168.1.x IP address format rather than just drawing from the DHCP server. One mobile device might connect but the Pixel just could not. Shutting off the extender and rebooting the phone now seems to connect the phone to the router.
I couldn't understand this as this setup worked so well until recently. Hopefully now we can fix this and move on. Thank you all for your prior help.

Now it is working but new devices are not provisioning or connecting to the Internet. I've got 15 wireless devices connected. My laptop now will not connect. On the 2.4Ghz I can connect but will not be provisioned Internet access. On the 5GHz I am denied a connection to the router with Windows informing me "You cannot connect to this network".
Has a factory reset and setup from scratch been performed since last FW update?
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute them back ON.
https://community.netgear.com/t5/Cable-Modems-Routers/General-info-and-Troubleshooting-for-Cable-Modems/m-p/1530376#M12853Thanks and sorry for the late reply. I didn't get an email there was one. I am still having serious problems as now WiFi does not show as provisining and all phones get "no internet access". After about a year and a half, these problems began out of nowhere and persisted.
- performed a hard reset and that worked better for a few days, at best, before the problems began again

- Checked
Be sure there are no coax cable line splitters in the between the modem and ISP service box.- None and, if there is one or an extender, it was installed by my cable company
Be sure your using good quality RG6 coax cable up to the modem.
- Runs straight from the wire to the modem
Be sure to power OFF the modem for 1 minute them back ON.- I've not only done this, I've also done a hard reset too
What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 or 149 to 161 channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?
Try enabling any Beamforming and MIMO(MIMO may or may not be needed) and WMM features that may be seen. Under Advanced Tab/Advanced Settings/Wireless SettingsWhen this happens does both wireless and wired devices have problems getting internet access?
