DIAABLE AP ISOLATION ON CM3000

Since I started using this modem, many of my devices are not happy. SharkRF M!ke for example. I can not access shark rf link.

 

I am told  must disable AP Isolation, howver that is not an option when I go into the modem software.

 

Any advice would be appreciate on how to accomplish what should be a simple task.

      "AP" means "WiFi Access Point"  The CM3000 has no wifi radios, so that setting doesn't exist.   All the CM3000 does is connect your Eero router to the internet.  

       

      Who told you that you need to do this?

      Ok, so how exactly is the Zumspot connected to your network?  Is it connected with ethernet to the Eero?  Or is it connected to the Eero with WiFi?

       

      Note you can only connect one device to the CM3000 ethernet.  So you only connect the Eero to the modem.  Any other ethernet needs to be connected to the Eero.

       

      Can you reach the Zumspot dashboard from your PC?

      This is connected to the Eero WiFi?

  • The pi-star device is called a Zumspot and uses a raspberry pie based tiny computer to manage the internet connection again via my 2g wireless network. So to get everyting to work, my computer, the M1ke radio and the Zumspot all have to be on the 2g network.

  • Actually the CM3000 has everything to do with the radio. The radio is basically a wireless device that connects to the wifi via another device called a Pi-star device, which connects via 2g to my wireless network. 

  • Everything is exatly the same. I was using ther eero before and everything was fine. The eero continues to work fine too.

    I am hoping that if I disable AP isolation my computer will be able to access Shark RF link, which I use to control the DMR radio. 

    If you are not familar with DMR basically it is a system that allows ham radio operators to talk literally around the world via an internet link. In fact I was just chatting with  guy in Chine not 5 minutes ago.

    The CM3000 modem has nothing to do with radio use. Not WiFi. Not any sort of radio.

     

    Is it correct to assume that the only thing that changed was replacing a previous cable modem with the CM3000?

    i.e. the WiFi router system remains exactly as it was before the change?

     

    and.... this M1ke product was connected to WiFi and working correctly before the change?

      Yes it worked just fine.

      The m1ke still works with this router but I need to be able to access the Shark RF link webpage to control it, i.e add DMR channels etc/

  • I have a Netgear Nighthawk CM3000 and an eero mesh networtk.

    It has wifi just fine, 2g and 5g.

     

    AP isolation hopefully will solve my problem

    I never had this problem when I was using the Mediacom router but since I switched it seems that I have had problem after problem.

    I am a ham radio operator and have lots of stuff that will only use 2g.

      Did you install the Eero at the same time as the CM3000?

       

      This sounds like an Eero issue.

        The eero was in use prior to the router switch over and seamlessly hooked up to the CM3000 and continues to work fine.

      I am trying to connect to Shark RF link to access my Shark RF M1ke  DMR transceiver which. The Shark RF link is used to control the M1ke. I requires the my computer and the M1ke both be on 2g which is no problem, I can easily switch from 5g to 2g. Lots of my ham stuff only use 2g.

    The modem is not a router and also has no wifi.    You likely have a router, and possibly wifi extenders.  Can you give details on that equipment?
