Unable to connect Chamberlain garage door opener via 5g internet

I have 2 MyQ openers on separate buildings. Both of them easily set up initially and worked perfectly. About a year ago they both went offline for a couple weeks.  I resolved it by doing a factory reset and restoring the SSID and password. The same thing happened again 2 weeks ago. Devices went offlline and I did the factory reset tonight. Once the SSID and password were restored both devices immediately were back online. I realize that this is a temporary fix, but thought it might be helpful to know that it wasn't always this way. I expect that the change happened during a software update and I'll be back offline when the next update is pushed out. Looks like I'll be adopting the solution recommended here. Thx for sharing.

I am also unable to connect my parents Genie/Aladdin Garage door to their T-mobile router.

I wonder if this is the same issue….

I have tried numerous ways with no sucesss.  I have changed the WEP protocol on the Router (the options are pretty limited) and I have tried to manually configure the garage door ahead of time.

How can I tell if the problem is a closed port…

Does T mobile router have a way assign an ip address to device?  

I am hoping that T-mobile will enable more features on their router to help get around issues like this.  There is not way that Genie connect will keep up with changes in protocols or even bug fixes

I spent about 45 minutes using chamberlain live chat.  After resetting to factory settings, I was able to get the garage door to open and close from the app again. You have to reset both WiFi and garage door opener for it to work.

I bought a Wi-Fi extender and connected it to my Wi-Fi then connected the garage door to the extender and it worked my garage door is back online.

I found a quick easy solution for this. I have an old netgear N300 extender when I used with Comcast router to provide full house coverage. Now with t-mobile home internet router I do not need that extender anymore for coverage. I setup this extender again to create a 2.4 GHZ network for my MyQ to connect to. It worked like a charm.This 30 dollars extender will do the trick. 

Yeah this worked like a charm for me too and an added benefit was I was able to hook up my home surveillance system which is nowhere near the T-Mobile router and it requires a lan cable so i  have my surveillance system and garage opener both running through the extender

T-Mobile:  You are making things way too complicated for new users.  I found that if I just carry my T-Mobile box into the room where I am trying to connect a device to the T-Mobile service, plug it into the same electrical circuit that my device is plugged into I can set up anything I want to.  I have successfully set up two ROKU devices, MyQ smart garage door opener, my Ring Doorbell Pro and a Ring Spotlight camera on my back patio.  The T-Mobile box likes to be in a window for the best signal and when I was in the garage doing my MYQ smart garage door, I just left garage door open and I got the best signal of anywhere in the house.  Everything connects right up, as long as you follow the exact steps set forth for each individual device and they all prompt you through very easily.  If a female 75 years old can do this, I would think anyone could!

GET THIS $#!% FIXED TMOBILE.  I have been in "offline" status with MyQ app for my garage door opener for 260 days, per the app.  Numerous times I tried to reconnect my garage door opener via MyQ app to my T-Mobile wifi over the past 9 months or so.  Finally today, I called MyQ thinking it was user error following the app instructions.  After confirming that I was following the instructions correctly, the rep asked me what did I use for internet service.  As soon as I told him TMobile, he said that is the problem.  There is a known issue with TMobile and the settings that come with their home internet units.  Sure enough… I googled Myq and Tmobile and voila!  Here is more than 1 year of complaints on this topic.  RIDICULOUS.  I had TMobile when I originally bought the Chamberlain garage door opener and the professional installer was able to get the MyQ app to work and it did flawlessly until TMobile upgraded cell towers to 5G and sent me a new tower.  Since that time, I have not been able to use MyQ app.  GET. THIS. FIXED. TMOBILE.  This is almost 2024 and this should NOT be an issue. 

While I am grinching… consumers pay entirely too much per month for any cell tower to be down.  Too many people rely on cell phones and related services for any tower to be down or providing low signal.  It is not only dangerous (i.e. elderly relying on wifi to support their health devices should the fall and need to call 911; wifi supported security cameras, MyQ Apps to see who is coming and going at your home...etc.) it is irresponsible.   Someone should be camped out at those towers 24/7/365.  

After many hours of trying all options, talking with the (useless) T-Mobile tech support, and reading T-Mobile forums, seems that not only is there an issue , between what Chamberlain needs and what T-Mobile accommodates this is a moving target and depends on router version and MyQ version. Different people have different solutions. I could not get MyQ to work through either of two standalone WiFi routers that were physically connected to the T-Mobile router to connect, that is unless I had the standalone WiFi router network open - no passcode.  Ironically, MyQ works fine through my T-Moblie 5G phone hotspot. So I'm done fooling with this, left the standalone WiFi network open and had the standalone router MAC filter and only accept the MAC addresses of my garage door, phone WiFi, and laptop WiFi & ethernet ports.  Note that MyQ is not the only device that does not connect via the out-of-the-box T-Mobile gateway plus the gateway is the worst router, as far as features available, I've come across since setting up my first WiFi network in 2001.

Was having the same problem .bought a cheap wifi extender off Amazon for 13 bucks. The wifi extender not only extends the wifi single but creats it's own wifi name and is able to connect to the myq

I got my Chamberlain Internet Gateway accessory (old 2014 CIGBU model) working with my Chamberlain HD930EV garage door system in the myQ Android mobile app v5.262 again! 8/2024 

After doing a factory reset, I plugged it into my T-Mobile 5G cellular modem/router (Arcadyan KVD21, firmware v1.00.23) and it was recognized, and I followed the steps in the myQ app to set it up. It was not recognized by my new AT&T Humax BGW320-500 fiberoptic modem/router earlier. It was working fine for years with Asus routers in a cablemodem system.
