WNDR3700v1 - Unacceptable LAN device detection when connected to WiFi

Hello,

 

Firstly I hope I'm not repeating a topic that exists but my searches have come up mostly empty.

 

First to outline issue - When I conenct to the Router's (WNDR3700v1) WiFi APs (5GHz or 2.4GHz) it takes a solid 5-10 minutes before the LAN devices are accessible/identified.

 

To help with troubleshooting I actually have access to 2 of the same device, as they were purchased on the same day to use in different houses, and the issue persists across both when using either device.

 

Along with this Router, we have an AirPort Express device in the lounge room which acts as a network extender via Powerline which identifies and lets you connect to LAN devices immediately upon connection.

 

I am not a networking newbie by any means, but far from an engineer.

 

Please help!

  • Thanks for the suggestion Doraemon, but we've decided to simply replace the router. It's been in use for almost, if not 4 years and it's time to get something with AC wireless now that the standard has matured considerably.

     

    I was really hoping someone had experienced this or knew of general reasons why this could happen, and while there were suggestions which saw improvements they are not in any way feasible to our network configuration.

      Thanks for the quick response!

       

      Our router has an 8 port gigabit switch hanging off it which connects to the powerline so I just unplugged the powerline from the switch and hey bang presto when I connect to the router (after a reset) LAN device detection is instant.

       

      Preempting and taking the test further I plugged the powerline back in and turned the AirPort Express back on, switched over to its wifi AP, instant LAN devices, then switched back to my Router AP and back to the waiting game.

       

      Do you have any configuration suggestions with the option of keeping my existing setup, or at least the powerline?

        check the settings on the AirPort you may have two DHCP servers fighting each other

         

        use 1,6 or 11 for channels do not use same channel on both
