Microwave Interference

Model WNDR3400v3 Firmware V1.0.1.4

 

The microwave keeps interfering. I have the channell selction at auto. Often it is on Ch 8.

 

What can I do to eliminate microwave interference??

    yeah . . say, i did try chnaging to ch 1. We will see how that goes in the next day or 2.  OK?? I mean if I could switch to 5 Ghz that would be great .. but I did chnage the channell. I noticed all my neighbors are normally between 6 and 8. So I will give 1 a try . .

  • Your WNDR3400 is a dual band router, so switch any devices to 5 GHz, if they are capable.  Microwave ovens nominally operate around 2.45 GHz, which is around channel 8.  Try using channel 1, provided that it's not too heavily used by neighboring Wi-Fi networks.

      What do you mean by switch any devices to 5 Ghz?? I guess I cant do that because it is interfering with the wifi going to my ROKU. This makes it so I cant use the microwave and the ROKU at the same time. I will try chnaging to ch 1 as you sugested. I just hope it will work good enough for the rOKU.

        Your WNDR3400 has two Wi-Fi networks, one that broadcasts in the 2.4 GHz band and another in the 5 GHz band.  Many devices, such as laptops and smartphones are capable of operating in either of these frequency bands.  My suggestion was for you switch those devices to use the 5 GHz network.  If the 5 GHz network is not enabled in your WNDR3400, then turn it on and set a Wi-Fi password on it.

         

        What's the model of your Roku?  Some of their models can operate at 5 GHz.
