AC1750 WiFi Mesh Extender (EX6250) - Connected but no internet (only on channel 2.4 Ghz)

Hello,

I have the AC1750 (EX6250) repeater which was working fine until yesterday, and for some reason I don't yet know, the 2.4Ghz wifi network stopped having internet. It is clearly visible on the network, but devices can no longer connect to it.

 

Another thing too, the 5Ghz network works perfectly, nothing to report, but not all my devices support 5Ghz!

I did the factory reset and the reconfiguration via the Nighthawk application, but nothing worked, impossible to have the 2.4ghz wifi network working

I've done the reset several times, and I have the same problem on this channel.

 

What can I do to resolve this issue?

 

Cordially,

    Did you set it up using the push button WPS option? 

    If so, factory reset the extender  and set it up using the installation assistant.

    To factory reset, push and hold the reset button for 7-15 seconds while powered on. 

    Here's a video of how to use the assistant.

      Hello  plemans 

       

      my extender is connected to --> Nighthawk AX6000 AX8 8-Stream WiFi Router (RAX80)

       

      I did not use WPS for the setup, i used the NightHawk Android Application.

      I've, in the past, already done some factory resets & setups without issues.

       

      Regards,

        Make sure you're not using wpa3 on the router. 

        Try the installation assistant and not the app
