Can't connect to ORBI channel sometimes

Can't connect to ORBI channel sometimes

We are in a small office with the SRR60 and a single SRS60. Firmware V2.7.0.122.

Everything configured and working for over a year. No recent changes other than firmware updates when available.

4 channels: Admin, Main employee access channel, IOT channel and a guest channel.

One day a user couldn't connect to main channel. Left the office, came back to the office the next day and could connect.

I am the admin. I had the same experience the next time I was at the office that I couldn't connect to the main channel. I then tried connecting to the Admin channel and got connected. I then disconnected from the Admin channel and connected to the main channel without an issue.

Other users come and go and have yet to have a connection issue.

I don't see anything in the logs about rejected connections.

I have done a reboot from the ORBI web interface.

I would rather not do a factory reset and then have to reconfigure.

Anyone else have a similar situation lately?

Are you on iOS (and the coworker with the issue)?

Are you using random ip/mac address?
or icloud relay?

The laptops in question are Windows 10.

No iOS or Android devices seem to be having the problem.

I am using dynamic ip addressing with the ORBI performing DHCP tasks for LAN assignment.

For internet ip address the ip is dhcp as well from our provider.

Re: Can't connect to ORBI channel sometimes

Looks like that modem is a modem/router combo device. 

It can cause a double nat. it usually doesn't cause a lot of issues but it can. 

A double nat happens when you cascade more than 1 router.
https://kb.netgear.com/30186/What-is-Double-NAT
Fixes? There’s 3 options but only use 1.
1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions. Not all ISP's modem only mode works properly. 
2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference
3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.

The Spectrum modem is in bridge mode currently.

Has been working that way for over a year. Current issues are new.

I am going for a factory reset to start over as issues are sporadic.
