Unable to connect Chamberlain garage door opener via 5g internet

There is actually a confirmed solution for this as I had exact same issue everyone else is complaining about.

You can't connect directly to the TMO router. It just won't work. 

I resolved this issue with a WiFi extender but you have to make sure it runs separate 5ghz and 2.4ghz networks. Mine was $50 on Amazon. Model shown at this link. 2022 WiFi Range Extender Signal Booster up to 5000sq.ft and 35 Devices, Internet Booster for Home, Wireless Internet Repeater and Signal Amplifier,4 Antennas 360° Full Coverage https://a.co/d/eBZMKlh . Then when you go through the process to add the chamberlain opener don't connect directly you the TMO router but instead connect to the 2.4ghz network created by the extender. Boom. First attempt to connect worked. 

I had the TMHI Nokia Gateway and no issues with MyQ. Installed an TMHI Arcadian Gateway seven days ago and my MyQ devices no longer work. Tried talking to Chamberlain support but it was pretty useless ("T-Mobile is 5G, we require 2.4GHz").

Looks like a WiFi Extender is the preferred solution, will go this route and hope one of the two vendors solve this issue in the near future.

Finally it works.  I got TP-Link RE200 AC750 wifi extender on Amazon ($27). I setup only the 2.4g network on the extender, and after I set it up, went into the extender app and turned OFF the 5g network (as it had set itself up, even though I said skip during set up).  Still the garage door would not connect using the MyQ app on my phone.  So, I got out my ipad and downloaded the MyQ app (and yes, there are some differences between the phone and ipad versions).  Set my ipad to the 2.4 extender network.  I deleted the existing garage door opener in the MyQ app and started from scratch, adding it back in as a new opener.  Tada! it worked.  Hope this helps someone else. 

Interestingly, this evening i can operate my garage door via myq app.  I took no action.   do any of the posters on this thread experience the same change?

Thanks Shivaslrons. I ended up setting one of my laptops up as hotspot and connecting that way for now. Hopefully they'll come out with a fix soon!

I had the same issue today and upon digging further, I was able to correlate my issue to the current version of firmware on the Nokia device.  It automatically updated 23 days ago and that was exactly the same time the MyQ app was saying it was offline.

I proceeded to reboot the modem with no change.  I think learned the MyQ to a phone hotspot and it worked fine so I knew the issue was with the T-mobile ISP service.  I then tried to reconnect the MyQ to the T-mobile and it still didn't work.

The final step that fixed my issue was to perform a factory reset (not just reboot) on the Nokia modem from T-mobile.  I am happy to report that it my garage door is back to working normally now.

• ShivasIrons:  Your reply gave me hope so I just tried again.  Still does not connect.

Both my openers don't work.  I think it's not compatible with 5G.  My openers are 2.5 years old.  It was saying it only run on 2.4 ghz I think when I try to setup.  I will have to go back to CenturyLink and it's cheaper.

T-Mobile is overcharging for Home internet.  The gateway basically a basic device cannot do many things like extender and poor coverage outside of the house.  It should have been $25 or offer 2 gateways for $50, even that my garage openers still don't work..🤬

I purchased a new Netgear extender as recommended by T mobile and I assumed it was at factory settings but using the Netgear app, it would not connect to the netgear online set up.   I sent it back to Amazon.   I have a Nighthawk extender but it connects to the Nighthawk router which did not connect to the Gateway .   I was told by T mobile that they were not compatible, so put them back on the shelf. Which extender connected successfully?   Gracias
