Just set up my gateway… working fine for the most part, but it doesn’t appear in the list of available networks on my Windows 10 laptop. Phone, tablet, another laptop elsewhere in the house… the network shows up just fine on all those devices.
Any idea what would cause this? TIA!

Well guess what, plugged the USB adapters in and both computers instantly recognized the T Mobile Gateway in both the 5Gig & 2.4Gig bands. Hate to have to buy the adapters but for a non computer literate its the far less frustrating option. Again thanks for all your help.
TKIP & AES is the only option with WPA/WPA2.
I agree that AES only is best, and is the only option with WPA2/WPA3 or WPA2.
I don’t think not using auto channel selection is an option with my gateway. Where do you see it?
other than the time I spend here in the forum, I spend less time fiddling with TMHI than I did with my 802.11ac router and spectrum modem or their predecessors. I remember trial and error with channel selection on my 802.11n routers.

Don't use auto for channels and always select AES, not AES and TKIP. Channels 3, 6, and 9 are the most compatible for troubleshooting. AES as well instead of TKIP or both. WPA/WPA2 is usually enough for most devices but being a decade old... WEP is a possibility for as high as the device might support when connecting. I have am old color laser printer that uses WEP at best when connecting to 2.4GHz WiFi. If you can, wire the device if the troubleshooting doesn't get it connected, if possible.
Dedicated 2.4 GHz network. (second network). It is Hidden because it is less secure than the primary default network. It is easier to establish initial connection if it is not hidden. (Change to Hidden later)
Here is what the default network looks like in T-Mobile Internet app. I changed the network name and password; the rest of the configuration is as it came a year ago. Most devices should be able to connect to this. The next post will be the dedicated 2.4 GHz network.
The support people don’t have hands-on experience; they work from scripts.
Since your USB Wi-Fi adapter is due in today, I’ll wait to see if that works for you. If you would like, I can make screenshots of how to connect with Windows 11 and also Windows 10.
In the meantime, here’s what my THMI network looks like on my 12-year-old Dell desktop computer (Windows 10). The driver is from Microsoft and is dated 2013. (This is just proof that it can work.)

First let me say thank u so much for trying to help me. No I haven’t tried any those. I’m an 81 year old neophyte when it comes to computers and how they should work. I can move around win 10 ok but I just got the win 11 unit in so the os is completely new to me. I was able to watch a you tube Video on how to boot the computer without Wi-Fi but have been stuck ever since just trying my win 10 to connect to the TMobile gateway, which I have had to work on an ethernet cable for over a year while trying to get someone at TMobile to help. All they tell me, in the end, is to call the mfg of my computer. Dell tells me the computer is past its lifetime expectancy so they can’t help.. Sorry to rant but I’m quite frustrated with the whole TMobile thing, they know they have an issue with pc’s so why don’t they fix it. My USB Wi-Fi adapter is due in today so I’ll try that next then determine weather to stay with Tmobile or move to Spectrum. Thanks again for your help, have to run to a DR appt. now !

Try setting the 2.5GHz security to WEP, if that is an option to see if that works.

Well i set up a new 2.4GH network but computers still wont connect. on the win 10 unit the “manage network screen shows both the 5G & 2.4G networks, however when I switch “show available networks neither shows up. on the win 11 unit doesn’’t show either. I ordered 2 USB 5.0 WIFI adapters today which support both 5G & 2.4G.Hopefully they will work.
Thanks again for your help!!!
nc1037, thanks soooo much for your response. I see that the instruction links u provided seem to be for Apple & Android iOS, are there any for windows 10&11 pc’s?? Thanks again!!!
INSTRUCTIONS
Some devices, such as printers, have trouble connecting to the gateway’s default configuration.
You can have several Wi-Fi networks on the gateway. You want to leave the default network alone (2.4 & 5 GHz; WPA2/WPA3 and AES security) and add a second, dedicated 2.4 GHz network. This second network is for devices that can’t connect to the default 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. (The encryption will automatically change to “TKIP & AES”) Try connecting your device to this second network.
Use the default network for your other devices, as much as possible. Note that WPA/WPA2 (on the second network) is less secure, so I recommend setting this network to be Hidden. You can hide it after you get your devices connected to it.
Here are the T-Mobile support instructions for how to add the second network with the app.

I hav the same problem as many above. Two Dell lap tops, 7440 & 5440, one running win10 (7440) and one win11 (5440) neither can find the TMobile gateway, however both can connect to other Wi-Fi routers with no issues. After several hrs on multiple occasions with TMobile tech support no luck. Have iPhone 14’s, iPad Pro, iPad Air 2, Amazon Alexa all of which can access the 5G Gateway with no problem. The 7440 is about 10+ years old and the 5440 is 1+ year old. I just found this page so sure would appreciate if some could address my issues, so frustrated I’m about ready to trash the TMobile Gateway and go to Spectrum!!!
All this is a common issue because of the age of your client device(laptop, phone etc). This is because the wireless card in the device does not support the newest 2.4ghz bands that the T-Mobile devices comes defaulted to.
You do not need to buy an extender or any other piece of equipment, only change one setting on the router.
You will want to log into the router settings, theses are found on the bottom of the T-Mobile device.
Navigate to:
Due to the age of the device it is not a big deal to have a lower transmission speed on the 2.4ghz channel - all modern devices will connect to the 5ghz channel or WiFi 6 if your device supports it.
Hope this helps!

I don’t know if people are still having this problem. I am, and it looks like T-Mobile has removed the ability to make these kinds of changes. The left side menu is not there anymore when I go to my gateway’s IP. I’m thinking of trying the range extender solution...
I could not see any networks on my Windows 10 computer and wifi was working but disconnected, so I was without internet access. To reconnect, “Devices” did nothing--I needed to search on “Services,” then WLan AutoConfig, Start-up Type Automatic (it had said Manual), Apply, and Start in left panel. Then all was back to normal. Hopes this helps someone else.
This is how I fixed my issue with an old Dell Notebook PC with the following network adapter:
Intel(R) Dual Band Wireless-AC 3160
I simply went to Device Manager, located that network adapter in the device manager, uninstalled it by right-clicking on that device, and then go to ACTION, “scan for hardware changes”, and then the WIFI network came up immediately!
Hope this helps!!!
Sorry to say, did not work for me. Same AC 3160. Did you check “Delete the driver software for the device” ? I did not. Thank you.
The t-mobile router doesn't work with some Dell computers. T-mobile Philippines support was clueless, and so was Dell. I solved the problem by connecting via a wifi extender.
Solved! The issue is your Proxy Server.When proxy is enabled, your network data gets transmitted differently than it would when proxy is disabled.
Therefore, turn the proxy server off on your PC and see if that helps you get rid of your problem. You can always turn the proxy server on with a few clicks. Here is the link to how disable the proxy server.

Here’s how to disable proxy:
Some older computers and devices don’t work well with the default network settings. You should leave those settings alone for all your devices that do work well. But if your computer or other device can’t see the default network, you need to add a second network.
Here are T-Mobile’s instructions for how to do this with the app.
Same issue after re-starting router home PC doesn’t SEE router but other devices in same room work Fine. It is STUPID that tech support is a community share and NOT T-Mobile techs fixing the problem. Oh and the app locks up anytime I attempt to see devices
I switched to T-mobile over a year ago and I’ve had to keep our old provider allllll this time, because 1 desktop PC in the house couldn’t find the gateway.
All total, I probably spent a solid week’s worth of time reading these forums, doing all the stuff posted here, having support walking me through fixes (that failed), and even reading forums and support from other companies, whose users were having the same issue with those products.
I even tried skipping the wireless and plugging it into the Ethernet port on the gateway, since it’s a desktop PC and not going anywhere, but those hopes were crushed when I discovered it’s in the one place in my house where the gateway couldn’t get a signal.
Last week, I was putting in a grocery order in at Walmart, not even close to thinking about technical annoyances, and I had a brain storm. I added a USB wifi adapter to the grocery order. When it arrived, I plugged it in, ran the setup, and BOOM! the T-mobile gateway appeared on the list.
A whopping $9.99 and 5 minutes solved the problem. The desktop PC is online, its user is happy as a pig in slop, and I can FINALLY kick my old provider to the curb.
Sometimes it pays to think outside the box, and inside the Walmart bag. 😄
I have the same issue with an old Windows 7 64-bit laptop that cannot detect the Wireless connection, I change the 2.4GHz transmission mode to n/g and the T Mobile Wireless Network was instantly detected. After that everything is working fine with a download speed between 21-29 Mbps.
I had same issue one of my laptop wasnt connecting to 5 GHz gateway. However connects to 2.4 GHz gateway automatically without issues.
Same situation
