Unable to connect Chamberlain garage door opener via 5g internet

Update***** I WAS FINALLY ABLE TO CONNECT!! No one ever called me back as promised by t mobile or Aladdin Genie…however I decided to try to connect my T Mobile device to my old router I used w the previous cable Internet provider (netgear brand). It took a couple tries but it finally connected under the router. Hopefully it continues to work. I hope this helps you fellow strugglers lol 

First of all, I separated the 2.4 GHZ network from 5 GHZ network from t-mobile internet app (choose network you will see the option). All I did was to reset extender to factory default setting then I can use my laptop to connect to the extender network, and a simple configuration screen shown up. The very first step was to let me pick which WIFI network extender should connect to. I picked the 2.4 GHZ one from T-mobile home internet router. Then provided password for extender to connect. Now I have chance to pick a name for extended WIFI network. 

Now I have extender WIFI network created and be able to connect to through phone or laptop. 

I went to garage, reprogram the WIFI to connect to this extended network. Garage has no problem to connect to this network. Everything comes back green.

You might need to download a manual of your extender to find out how to reset to factory default settings and configure an extended network for use.

All MyQ needs is at configuration time to use port 8883 to connect to your router or extender to register. A router or extender works well for this purpose. But extender is cheaper and easier to place closer to garage. Mine just needs a power plug.

I FOUND A FIX FOR THE CHAMBERLAIN

Hi all.  I recently installed the T-Mobile 5G internet and ran into the same issue.  I discovered a work around for this issue.  I bought a ORBI91 router from Walmart.  I plugged it into the back of the T-Mobile device and was able to create another network.  The Chamberlain recognized the new ORBI network and is now working with MyQ.  I still have my TMobile network as well.  Maybe other routers will work as well.  I am not for sure.  The Orbi was the 1st one I bought.  As an additional bonus, when I have guests over and the want to join my network, I am going to give them the Orbi network and keep them off my personal network.  

Hey give it a shot.  Maybe it will work for you as well.

Still having issues.

Configured one garage opener to use the HotSpot on my TMOBILE cell phone, the garage door works fine in MyQ app.

The other garage door thats on the TMOBILE home WiFi still doesn't work.

TCP 8883 is blocked either in, out or in both directions on the TMOBILE home router

I am having the same issue with my smart garage. I don't have the Chamberlain, but the Genie Aladdin. No issues connecting any of my other devices to T-mobile. My garage had no problem functioning off of the cable internet. Spent a great deal of time on the phone with both T-Mobile and Genie. Neither could figure it out. It says there is wifi available but it will not connect the device. The service is strong in the garage bc I did internet speed tests on my phone. The most frustrating thing about it was the gentleman I talked to from T Mobile had me reset my T- mobile box disconnecting EVERYTHING in my house from wifi to resolve the issue. It did nothing but cause a ton more work reconnecting everything that works. Waiting on calls back from both companies but after reading this I am starting to feel like this is an issue all around for those of us with smart garages. It needs to be resolved. I rely way to much on the functionality of the smart garage door with my kids. I tried to tell them what I was reading in the comments here but it was crickets on their end. They acted surprised. If anyone has any recommendations on how to resolve this I am all ears!! Already tried separating the combined networks. It did nothing but cause a hassle. Restarted devices/reset devices. I am at a loss. 

i spent time with T-Mobile support last Wednesday.  The tech acknowledged that the Nokia router does not have port forwarding active at this time.  there are efforts in work to address this 'feature' which is causing MyQ to not connect.  No ETA on the 'fix'.  

Hum, over the weekend MyQ started working again as my opener connection indicator is solid green.  Still connected this morning.  I took no action with either the app nor the router.  

I had the older white box router and my MyQ garage door opener connected just fine. Then the router started acting up and the 2.4 networked gave out. I called tech support and they sent me the new grey router. Got all the smart devices in my house reconnected except the garage door opener. Called Chamberlin's tech support and after walking me through the steps they said it's the routers fault.

I have spent much time and research with trying to connect to MY Q/chamberlain garage door opener wifi AP since changing both my phone and internet to T Mobile.   My recent contact with a Chamberlain support person has me certain that the problem lies with security settings within the Gateway router. Reading these posts and following recommendations from both My Q and T Mobile support  , it seems most likely that it is an issue with Port 8883 being blocked.   I am unclear how to "unblock" port 8883. 

I was told by T Mobile that the Gateway settings cannot be changed as it is preset and a plug and play device.  All of my connected wifi devices are working EXCEPT the My Q app.  

Any updates on how to remedy this ?  Thanks so much!  

I tried connecting a Netgear extender but it didn't connect to my wifi network with the Gateway router. May I ask how you connected your extender?   

Gracias
