C3700v2 – N600 WiFi Cable Modem Sudden Issues
I've noticed my router had a firmware update because the admin screen doesn't look exactly the same. I am not getting a lot of 408 type errors when trying to open a webpage...basically, I'm getting ...
I found a solution....
For starters, I didn't even know my lan connection was off and I was using all router-modem wifi the whole time since I got with Xfinity. The wifi has issues, there's no denying that, but things went back to normal once I enabled my lan connection and started actually using the ethernet cable I had running from my Netgear to my PC.
So now I'm not getting the 408s, pages not loading in or lagging in, under my lan connection. The only other issue I had was the website I'm building wasn't working under lan but I solved that by making changes in the Netgear port forwarding.
I do have wifi usage concerns still because my Firestick uses the 5g channel and my PC was using the 2.4g wifi channel. Since the lan connection uses the 5g, that places both the Firestcik and my PC on the 5g, which means if somebody is watching a movie or gaming on the Firestick, there could...maybe be bandwidth conflict....maybe not.
Anyway, my Firestick is the only thing that seems to use the wifi just fine on the 5g. I don't really use my phone for internet while at home, so I can't really say how bad the webpage loading will be using the wifi for that device or the pad.
Conclusion...
Use the local network (lan) computer connection with a Netgear router-modem combo, if you're on the PC that the Netgear runs to with the ethernet cable or other cable. If you're on a PC that is not connected directly to the Netgear and you have to use the wifi...
You're in serious trouble because what people were saying on Amazon about my Netgear model losing wifi stability over time, was obviously no lie! I bought it because the overall review rating was not that bad but clearly...Netgear has some issues as a brand.
PS, that warning at the top of my Netgear Admin page about not being connected to the internet is gone. Yay!
You got lots of Criticals. Something the ISP needs to look into.

I would ask them to dis-associate the modem then re-associate the modem. Ensuring that the right config file for this modem IS being sent and applied by the ISP.
Power OFF the modem for a full minute then back ON.
Try channel 6. Channel 2 is a sub system channel, not a primary. 40 to 48 or 149 to 161 channel on 5Ghz
Ok I will talk to the ISP and report back.
Thank you for the help.
Ok I spoke to Xfinity and we did a factory reset while on the phone. They said from their end the router is not showing a factory reset, and the "boot file is not cleared". The tech mentioned it should be in Wallguard mode to accept re-provisioning. It isn't, so it can't be provisioned.
Did you press the reset button for 15 seconds or use the ERASE function on the modems web page under Advanced/Admin/Back up. I recommend using the ERASE function if you have access still to the modems web page. You might try this with the modem disconnected from the ISP coax cable.
Actually I used the "Factory Reset" button in the Administration page..Gateway Status.. Cable Information. I will try the Erase option in Backup Settings as soon as I get a chance.
SUCCESS!
I performed the factory reset with the ERASE button on the Backup Settings page - with the coax disconnected. After reboot I reconnected the coax and power cycled the router. Interface came up finally without the activation message and right now everything looks good.
Thank you so much for your assistance!
Glad you got it working. Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.
