Mobile devices randomly getting intermittent Wi-Fi connectivity.

This morning I noticed my iPhone was still connected to my Wi-Fi network but was unable to get connectivity.

 

After some general basic troubleshooting including, forgetting the network and reconnecting the device, power cycling the device, the issue appeared to be resolved.

 

However, fast forward a few hours later and the issue reappeared intermittently, following the same troubleshooting steps as before seemed to resolve the issue again, but only for about 30 - 60 min before becoming a persistent issue.

 

As a result I have also attempted to power cycle the CAX80, verified firmware up to date. Also verified via the router admin that it can see the device connected via the 5Ghz, the IP and MAC match what the iPhone shows, no duplicate information present, and access is allowed.

 

After mentioning this situation, my wife also reported the same issue with her iPhone briefly yesterday.

All other devices seem to be unaffected and working as normal. We currently have 10 - 11 devices via Wi-Fi frequently and peak between 13 - 14 when everyone is present.

 

At this point I'm unsure how to troubleshoot this.

    What FW version is loaded? 


    What channels are you using on 2.4 and 5Ghz? Try 1 and 40. 

     

    Set 20/40Mhz Coexistence to 40Mhz only Under Advanced Tab/Advanced Settings/Wireless Settings

      "What FW version is loaded?"
       Modem is currently running V2.1.5.2.

       

      "What channels are you using on 2.4 and 5Ghz?"

      2.4 was running on 7 and 5 was on 36, I will update to 1 and 40 and see if there are any changes.

       

      "Set 20/40Mhz Coexistence to 40Mhz only"
      Just to make sure I'm understanding this correctly, in order to do this would I just need to untick the 20/40 Coexistence, as my advanced page does not appear to show a "40Mhz only" option.

        Update FURRYe38 

         

        I have changed the 2.4 and 5Ghz from Auto detect to specifically channels 1 and 40, also toggled the 20/40Mhz. After doing these changes the issue returned right away so I power cycled my iPhone as well as the CAX80, but still encountered the issue.

         

        I enabled the 20/40Mhz again, and that seemed to resolve the issue for over an hour. However, as soon as I moved the iPhone from the room the CAX80 is physically located, the issue resurfaced.

         

        Additionally, I discovered our iPad is also now encountering the same issue as the iPhones. All other connected devices remain unaffected.
