C7100V Xfinity WiFi not working for 2.4 GHz, but 5 GHz is fine
My router is really a Nighthawk AC1900 WiFi (C7100V) for Xfinity, bought on 6/10/2017, so it is now out of warranty. It has the latest version of the firmware. A few days ago, the 2.4 GHz WiFi stoppe...
I have attached an RTF file with screenshots of my C7100V's wireless settings and logs (can be resized for easier reading), taken after a factory reset. The 2.4 GHz radio is still not on. It's front panel light goes off as soon as the DS/US light starts flashing, while the 5 GHz light stays on. Note in the wireless settings that the 2.4 GHz mode is not set, while the 5 GHz mode is; if I try to set the 2.4 GHz mode, then the 5 GHz mode gets set to a low value. Same nonsense happens if I try to set channels for the two radios. Let me know if you have any ideas.
Thanks.
