Netgear C7000v2 Firmware V.1.03.03 5G wifi problem

Question

I have AC1900 C7000V2 Modem Router connected to Xfinity.

The firmware is V.1.03.03.

Just recently (less than a month), the 5Ghz-wifi connection is unstable while the 2.4GHz is working fine. Most of the time the 5Ghz connection is lost and force to back down to 2.4 GHz.

I try to factory reset and it still has the same problem.

Do you have any suggession?

I am having the same problems on the same device. The xfinity technician told me to get a new modem/router, I got a new one and it is also experiencing these problems. I thought my old modem/router was broken, but it seems to be the firmware update that is causing it. It used to work just fine before.

What Firmware version is currently loaded?
&nbsp;
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?
&nbsp;
Has a factory reset and setup from scratch been performed?&nbsp;

I'll try the channel change - there are a few visible networks around (no telling how many aren't broadcasting their SSID of course)

Haven't done a full reset in a while - might try that too

thanks!
