Can't connect to ORBI channel sometimes

Question

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.&nbsp;

Looks like that modem is a modem/router combo device.&nbsp;
It can cause a double nat. it usually doesn't cause a lot of issues but it can.&nbsp;
A double nat happens when you cascade more than 1 router. https://kb.netgear.com/30186/What-is-Double-NATFixes? 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.&nbsp;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 interference3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features. https://kb.netgear.com/26765/Which-features-are-disabled-on-my-NETGEAR-router-when-it-is-set-to-AP-Mode
