MyQ (Chamberlain) garage door and Gateway 5G router not compatible

I think you could get it going with the second network with different security settings than the first network.  I understand that is more than you want to tackle by yourself.  Please ask a tech-savvy friend to help you; follow the instructions in my post on page 1 of this thread (the last post on page 1).  That is Step 1.  Then, Step 2 will be getting the home security and/or garage door opener connected.  I can’t help with that.

The alternative is to try another internet provider.  

Good luck.  

I’m sorry.  Unfortunately, I have never heard of a T-Mobile tech going to a home.  You might ask a tech-savvy neighbor or friend to help.

Just tell me, did it work before, with the first T-Mobile Home Internet gateway? 

@fitisit2012  If I understand correctly, your home security system was working with the first gateway.  So the technician should not have said “nobody has T-Mobile internet” or that Vivint doesn’t work with T-Mobile internet.  Do you remember if the first gateway had more than one Wi-Fi network? They come with one, but more can be added.  Many people have added a second network to handle garage door openers, printers, older computers, etc.  Your first gateway might have had that, and now your Vivint system can’t find it because it doesn’t exist (yet) on the replacement gateway.  Please read the instructions for creating a second network in my post which is the last one on Page 1.  Do you remember if you or someone else did that before?  Do you know the SSID (network name) and password that the system was using?  If you can remember, make a new network on the new gateway with the same SSID and password as before.  If you can’t remember, you should go through these steps -- but you will also need to connect the security system to the new network.  You may have to have the technician return.  You might need to show him the T-Mobile Internet (or T Life) app on your phone.  Avoid changing any settings for the first network which I am assuming is working for other devices in your home.

You could try setting up your Orbi extenders as you had them before.  I’m not too familiar with them, but I assume one part connects via ethernet cable to the gateway.  

Here are more detailed instructions for adding a second network to your Gateway.  (Not using Orbi).  These instructions are for the T-Mobile Internet app, but are about the same on the T Life app.

You can have several Wi-Fi networks on the gateway.  You want to leave the default network alone (2.4 & 5 GHz; WPA2/WPA3 security) and add a second, dedicated 2.4 GHz network.  

Add the second network with the + sign at the bottom of the Network tab in the T-Mobile Internet app on your phone.  For this new network, set the band to 2.4 GHz and set the WPA version to WPA/WPA2.  Try connecting your MyQ, etc. to this second network.  Use the original default network for your other devices, as much as possible.

Here are the T-Mobile support instructions for how to add the second network with the Home Internet app.

I have not, but I’m not sure I’m savvy enough. I do have Orbi extenders that I use to use with xfinity before their speeds or signal strength no longer needed it. 

I’m currently doing a two week free trial. In regards to streaming and surfing the internet I have noticed much difference between T-Mobile and xfinity. I thought I found a more affordable alternative and then I attempted to have MyQ, Ring and LOCKLY attached to the WiFi. T-Mobile doesn’t support them. Looks like I’m returning the T-Mobile Gateway and once again stuck with xfinity. 

I got MyQ to work using an old Apple Airport extreme. I plugged the router into the T-Mobile gateway and using the Airport Utility (from the app store) i set it up as it’s own network. MyQ connected right away and no cost to me. I use all Apple devices but Androids should be able to set it up too (maybe). I know it will work on Window machines.

Originally bought a TP LINK and it didn’t work for me. I ended up buying a net gear and works with no issues ! Didn’t even have to mess around with the setting. 

I was trying to use a cable modem! Dug out an old ASUS that Sprint had given me, linked it to the TM gateway, fired it up, and MyQ liked connecting pretty easily! No need to buy new equipment!

I’ve linked the TMobile gateway with an Arris router. I don’t see anything new to connect the MyQ. Do I need to configure something new on the router to chose while connecting the MyQ?

Same issue here. I went to forward port 8883 and I cannot even login using 192.168.12.1

MyQ devices will not connect due to a block port on the TMHI gateway, only way around it is a secondary router

I use a TP-Link TL-WA855RE Router wirelessly connected to the TMHI Gateway. My two MyQ devices attach to it and I also have it located next to a device that only has Ethernet connectivity. Kills two birds with one device.
