Unable to connect Chamberlain garage door opener via 5g internet

I

This setup works. I had the same problem connect myq to t-mobile 5g home internet gateway for almost a year. I talked to chamberlain tech support many times and they were able to guide me to mess up the opener. I had to return the opener to Costco. Bought another one from Costco and decided to use it without the myq and camera.

I had a small wifi extender at home, setup as home gateway extender. IT WORKS!!!

I don't think T-mobile will change their protocols so I strongly suggest chamberlain publish this technique so other myq owners having the same problem can resolve their problems and enjoy myq.

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 did get an extender - set up as a wireless access point - to work.  But in the end, all of these are just KLUDGES.   The T-Mobile Home Internet simply does not work as normal ISPs do.   I suspect this is simply because they are probably paranoid about how much bandwidth will get consumed. But there are other ways this gets limited in any case - which should be sufficient.  Poor design.  I strongly recommend using your own home router (connected to the THI gateway) to overcome a host of issues related to this T-Mobile design.

At some point I am going to try out Verizon mobile internet and see if it has similar issues.  I am not expecting that it does.

i think for most of you you need the 2.4ghz connection and not the 5ghz.. mass majority of things out there need the 2.4 in order to work (irobot, door chime, ring camera etc etc). so if the router doesnt use the 2.4 or you have the security set up to i think it was WAP3 it no longer uses 2.4 and only 5 and if available 6ghz..which the above listed devices need 2.4.

I am not able to set up a wifi extender properly with either the Nokia or the Arcadian.

It sets up like one expects.  However, devices on the ‘extender’s wifi network’ can connect to its wifi, but cannot connect through to the public internet.  A phone, for example, will say ‘connected’ but ‘no Internet’.

No idea why y’all were able to connect  but I am not able to.

Netgear AC750 EX6100 extender.  Using only 2.4 GHz.

Where do I make a ticket? I just switched to T-Mobile internet from ATT bc they raised my

bill $11/month for the same shitty service have everything hooked up except my myq wifi garage door opener bc no matter what I do it won’t connect. 

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.

There may be some truth to that, due to default settings. Not sure if the Chamberlain device requires UPnP enabled, but newer (read: more secure) systems may have that disabled by default.

Mine worked with cablemodem + separate Asus routers.

Did not work with new AT&T fiberoptic modem with integrated router.

Works with T-Mobile 5G Arcadyan modem/router.

I use the very old (2014) Chamberlain Internet Gateway device.

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?   Thanks

Mine is old NetGear N300 Model EX2700. I got it at least 5 year ago.

I do not think you need to buy a new extender. Your nighthawk extender should work. Your extender always tries to connect to the “Known” network it has connected to. You need to reset it to factory default setting. At that time, you will be able to pick Gateway network. You need to download a manual to follow the initial setup procedure after resetting to factory default. Trust me, t-mobile support would not know your extender better than you do. Incompatibility is an easy excuse to get you off the phone.

Your netgear should work also. But your extender might only work for 2.4 GHZ network as mine does. So you will need to separate 2.4 GHZ network out from default t-mobile gateway’s hybrated network to create two networks for your t-mobile gateway. One for 2.4 GHZ, one for 5GHZ. At my home, 5GHZ is always much faster than 2.4 GHZ network. I have speed around 300 MBPS. So all my laptop/phone use 5GHZ network. But I leave this 2.4 GHZ for all the devices such as thermostat, smart devices. So far all works fine now.

Has anyone used the wifi extender solution for MyQ with the Arcadian Gateway? Had no trouble with  Asus and TPLink routers in bridge mode but with the Arcardian Gateway can’t get either to provide an internet connection.

The 5G in "5G Cellular" has nothing to do with the 5GHz in WiFi. Many people think they are the same thing. ‍♂️

I’m guessing T-Mobile has no interest in resolving this issue. Love everything else about it but this issue is forcing me to consider an alternative. So disappointed!

Yeah, I curse the geniuses that named these things. And eventually we’ll have 6G (sixth generation cellular) and 6 GHz Wi-Fi. Curses. Foiled again.
