2.4 network not working on AC2350

The 2.4 network is not working on my new AC2350 wifi 5 router/modem.

Network occasionally appears but can’t connect to it. 

Frustrating because some of my devices can only connect on 2.4 and there is no reliable connection. 

Need to return it?

AC2350 is not supported by Arris. Arris supports only the retail products that are available on but not the ISP lease products.

Do you have any Arris modem?


Hello, thanks for the response. It’s the SURFboard SBG8300 DOCSIS 3.1 Wireless Cable Modem with AC2350 WIFI which is on


Here is a link to it:

Since you are experiencing with intermittent internet connection on 2.4Ghz, I suggest you to change the Wi-Fi channels and monitor it for next 24hours of time.

To change the Wi-Fi channels, find the link given below:

If you are unable to connect the devices with 2.4Ghz, I suggest you to change the security mode by following the steps given below:

>Launch the web browser and enter IP address on the address bar.

>Login the Arris surfboard portal with credentials.

>Select Gateway>Summary>Connection>Wi-Fi>Network and select edit for 2.4ghz.

>Change the security mode as WPAWPA2-PSK(TKIP/AES).
