Full configuration of DHCP and other network services

Is there a way to get into a configuration screen for the KVD21 5G Gateway? Ideally, I'd like to connect my gateway to an existing TP-Link router to supply wireless and DHCP. I can work around the wireless by giving the KVD21 5G Gateway a separate SSID than the router, but I don't see any way to get into DHCP and configure or disable it on the gateway.

I understand that T-Mobile is looking for simplicity of use for the overwhelming number of users, and I certainly think that's commendable. Nonetheless, for those of us who understand the basics of networking, access to advanced features would be a major improvement.

  • Users do not have the ability to disable the DHCP on the gateway. The gateway cannot be configured in bridge mode either. Users can connect a second wireless router and have a double NAT solution but that is the only solution. If you go out watch the Nater Tater YouTube video you can see the workaround he has for disabling the wireless on the Arcadyan gateway. It is possible but T-Mobile does not promote this. Still it is a possible path to take. Nate clearly provides the information and it is not difficult.

    Hello folks, I'm another technical user, with RF experience and telecom background, along with IT and electrical engineer >20yrs. I went looking for PLEX and KVD21 remote access, that may be the only bust but it is what it is. I had tried out the trashcan device, and returned it after getting ATT fiber. BUT now ATT is doing the "bait and switch" with promo expired and "no promotions currently available" game. Similarly with Spectrum (cable), but I lose power frequently in my neighborhood and that kills the cable signal (regardless of home UPS/generator). ATT has a similar issue but they at least have some kind of UPS setup (so fiber is active during brief power outages). Have to use their huge device (BGW320-505); it's better than previous models and does Wifi6 (802.11ax). My issue is needing internet during power outages (ring doorbell!).
    Great current deal on device, in addition, they have a promotion for $100 gift card for new service from 11/10/2022 - 1/11/2023.

    I am facing issue where I keep Orbi mesh router in Router mode as I use parental controls, and there is no internet detected by Orbi on WAN port on Orbi web admin screen when I connect it to Arcadyan.

    Interestingly, if I select 'available via Orbi' Wi-Fi in android phone's available WIFI connections for Orbi router, device gets 192.168.12.x IP address and it works fine, but when I select regular Orbi Wi-Fi, device gets 192.168.1.x IP and no internet is available on it.

    So somehow Orbi is giving out 192.168.12.x IP to some devices even though Orbi is in router mode!

    Is this due to double NAT or IPV6 or something that is beyond my basic networking understanding?

    I see all devices given 192.168.1.x IP address by Orbi in admin UI, but I also see some devices given 192.168.12.x IP address in Arcadyan android app devices tab for the devices that can get internet through Orbi.

    I have not disabled Wi-Fi on Arcadyan and not sure if that contributes in any way to my issues.

    Any inputs on my situation are highly appreciated.

  • Rich, check that the Orbi isn't acting as a DHCP server. There can only be one DHCP server on a network, and the Arcadyan KVD21 5G gateway's DHCP can't be disabled. If you can set the Orbi up in Access Point mode, you'll probably have better luck with it.

    Bocaboy, I don't want to put it in AP mode so that I can use parental controls.

    I took out orbi rbk50 from junction box and plugged in a different ethernet cable directly to WAN port of orbi from arcadyn instead of using wire going inside the walls of my house to the junction box, and it resolved my above issues. 

    I am not sure why using the pre wired ethernet cable going inside the walls was causing these issues and I was using same cable for orbi satellite for backhaul without issues. Probably that cable goes through some switch or something that causes the issues?

    But with plugging another short cable directly to orbi works and everything is looking good right now including parental controls.

  • Rich, is it possible the cable in the wall exceeds 300 ft.? If so, that would be the problem. Ethernet is limited to 300 ft. before it would have to plug into a switch for another run. The Orbi might be able to make sense of it, but not the T-Mobile gateway, especially if it's a run close to the maximum Ethernet cable length.

    Bocaboy, my estimation is wire could be close 100 ft long but considering 20 year old house and potentially inferior quality of wire used by builders may be causing t-mobile gateway to not recognize an orbi router on the other end. What you are suggesting seems to be logical reasoning behind issue I was facing.

    Thanks for all the inputs!
