CAX30 - 2.4 wifi bad /5ghz good?

You may want to contact NG support and ask what your options are if the unit seems to be failing.

Not sure what's going on but all of a sudden the router won't allow connection via wifi 2.4 but does connect on 5 ghz.

Reset the router to factory specs - I'm using xfinity service

On several devices (phones, computers) - I told the devices to forget the 2.4 connection - upon refresh the 2.4 connection doesn't show anymore but the 5 Ghz is available and allows connection. Unfortunately my Ring Security system works only on 2.4 ghz among other older devices I have and without a 2.4 connection leaves many devices useless.

 

I went to total reset to factory specs to make sure no other settings were interfering with the 2.4 radio. Upon restart and even though the 2.4.light on the modem is flickering as it normally does there was no mention of my 2.4 connection on any of my devices - only the 5ghz showed and allowed connections.

 

Running Firmware Version V2.2.4.2  The modem/router has been working properly for months using this firmware. I would think that reverting to an earlier firmware wouldn't  change things since a factory reset didn't change anything.
