Possible Wrong Firmware Pushed by Xfinity?
I own a Netgear Nighthawk C7800 modem/router. I've had wifi connectivity issues for several days now with actual internet drops intermittently anywhere from an hour apart to a few every couple of min...
What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?
I have manually set the 2.4ghz channel to 6, which is uncongested in my area, channel 9 was default which was also not being used. Also, there are other signals being broadcast but very little overlap if any on the channel spectrum. I also tried turning off each SSID channel indepedently to see if the connections lasted any longer than the other but the same results whether they were enabled/disabled together or separately.
I have confirmed with Netgear phone support that the KB article is accruate for the FW version listed for the C7800 and that the current FW listed as installed on mine (V6.01.07) was the previous FW version for the CM1100 modem (which coincidentally is also a DOCSIS 3.1 GB supported modem). The CM1100 modem had FW V6.01.07 and is now being updated to V7.01.01 by Xfinity.
Question, do you know if using the reset pin on the back of the router is the same as performing a factory reset from the management page of the router? Just grasping at straws here as to how I might get back to an out-of-the-box state before any FW update was applied.
Try channel 1 or 11.
If the NG confirmed the KB is right, then you'll need to contact the ISP, ask for escalated support and have them confirm the version and if it's not right, have them send down the correct version...
The reset only resets any configurations that you have done and some back end FW stuff. I thought about having you do this however you may cause more problems or the modem may stop working and I'd rather you have the ISP push a correct FW file to the modem while the modems is mostly working. Check with the ISP and go from there first. If they send down the correct version and it gets applied, power OFF the modem for 1 minute then back ON, after it's ready, then press the reset button for 10 seconds then release. Then setup the modem from scratch...
