Wifi internet issues

The other night I noctied my phones were saying "Cannot obtian IP" while on wifi. The I tried to work for a little while and my work laptop would connect but would not get an IP address, so I had no internet. I unplugged everything and plugged it back and wifi was back. This morning same problems again. It seems to come and go. I updated to the latest firmaware this morning and still have same results. My orbi has worked perfect until the last week. Nothing in my network has changed. Any suggestions to resolve this issue?

  • One of the reasons that can cause such issues is having double NAT in your network. If your ISP modem is acting as a router and does NATing on the incoming WAN traffic then this can cause different issues since Orbi is also doing NATing. You need to check if you have double NAT.

    Please open a Command Prompt on any computer attached to Orbi and type:

    tracert 8.8.8.8    (traceroute to Google’s DNS server)

    1. If you see two private IP addresses listed in the first two hops then you have double NAT. Please check the model of your ISP modem and if you have a manual for it.
    2. If you see only one private address and the second hop shows a public address, then you’re all good and we need then to troubleshoot further to find the root cause of the issue,

      I only see one private IP, and thats the IP of the orbi. I have my cable modem set in bridge mode. All my wired connections are fine, I am only having issues with some of the wireless devices. 

  • What FW is currently loaded?
    What is the Mfr and model# of the ISP modem the NG router is connected too?

    What is the size of your home? Sq Ft?
    What is the distance between the router and satellite(s)? 30 feet is recommended in between them to begin with depending upon building materials.

     

    What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
    Any Wifi Neighbors near by? If so, how many?
    What WPA security modes are you using?

     

    Try enabling Beamforming and MIMO. Under Advanced Tab/Advanced Settings/Wireless Settings

      Thats a lot of questions, I'll try to hit them all.

       

      Both router and satalite are on 2.3.0.32

      Home is about 2700Sq Ft, normal wood, drywall contruction, satalite is about 30 ft away with good signal

      2.4 is on auto, with a lot of neighbors near by, I usually see about 5 other wifi networks. 

      Security is WPA2-PSK [AES]

       

      I just enabled the those two settings, I will test with my work laptop which seems to give the most problems. I have two android phones that come and go, but both are currently connected with no problems. Time will tell when I leave and come back.

        If you have alot of wifi neighbors near by, could a some wifi congestion going on. I would try a manual channel on 2.4Ghz. 

         

        Let us know how it goes.
