5g home internet - some sites won't load
My big gray cylinder 5G Home internet has good signal and works reliably. But some percent of websites I visit simply refuse to load via the TMo 5g device, yet they work fine if I use my Verizon cellphone data, or a coaxial cable modem (which I have not canceled service on yet). I am guessing it’s either a DNS issue between my Mac and the T-Mobile cylinder (eg: settings requiring technical help or updates), or a problem in the T-Mo network that is blocking some sites.
After spending too many hours on the phone already with Tmo tech support for 5G Home, I am not excited about the prospect of engaging on the phone again. It takes too long, and the agents need more training and support.
Has anyone experienced and solved this issue? Do you have technical insights? Is there actual written documentation somewhere that I could access? Thank you.
(Honestly Tmo, you need to rethink your support infrastructure for 5G Home.)

More likely if its 5G just like the phone, it is not you, its Tmo. They’re blocking UDP Access with 5G connections. Try a VPN and see if it works that way. I did that and the sites and access to voice programs like Discord and Skype worked fine after that. T- Mobile lies about their Data or does not give out proper information, Correct me if im wrong T Mobile ?

Thanks! I tried this on your advice. For anyone else reading this, let me save you some time. You can’t disable IPv6 from the System Preferences control panel. You can only set it to local. So I did that, but I also googled and found this Terminal command to disable it:
networksetup -setv6off Wi-Fi
And that does indeed show as “off” in the IPv6 panel of System Preferences, once you execute it.
So thus set up, I tried again, and… no change. :-/
Some further data though: The site loads on my iPhone via Verizon cellular data, but NOT when the iPhone is attached via wifi to the Tmo 5g Home router. So does that point to the router, not the computer?

I just got the Gray cylinder and neither of the MacBooks I own would see the internet although they were connected to TMo wifi. I tried again but used a vpn and they worked like a charm. This made me very confident the issue was DNS. I changed the DNS settings in System Preferences/Networking to 8.8.8.8 and 8.8.4.4 and the MacBooks worked great even without using VPN. It was a very simple fix. What is beyond frustrating is I spent 90 minutes on the phone with TMo support trying to fix this problem and they were absolutely clueless. Actually, beyond clueless. All they would do is keep having me reset the device. I truly find it hard to believe they haven't resolved this issue for other Mac users and documented it for the support folks who have to deal with the public. C’mon T-Mobile, you're better than this.

I have the same issue reported above with various random websites not loading on my 5g iPhone.
Yesterday, I went to get a covid test and my iPhone would not load the website to submit my insurance info…
This would not load on multiple browsers and I had no WiFi access.
As soon as I connect to my work VPN, I was able to load this website perfectly fine. Good thing I had a VPN accessible.
Any insight into why these websites are not loading? Is this a UDP issue as mentioned above?
FYI. The website mentioned earlier in this tread does not load for me either via 5g on my iPhone…

I am having the same troubles for the last 3-4 weeks when I use duda.co to develop websites. It is very intermittent too.
I had Duda Support help me and we disabled cookie tracking in the Privacy Settings of the current website I am developing. Now it is loading like normal for that site. Hope this helps people and T-Mobile Tech Support!

T-Mobile home Internet on Lenovo IdeaPad Slim 5 16IRL8 running up to date Windows 11.
I've had my TMO-G4AR for a couple weeks with a similar problem. I can get to "normal" internet websites but nothing that requires higher security.
YouTube, Gmail, and others are fine but I can't log into my bank account, credit card accounts, etc.
Also, I can't log into my Microsoft 365 apps on my laptop like OneDrive, Phone Link, etc.
Talked to T-Mobile tech support and they said it's something wrong with my Lenovo, talked to Lenovo tech support and they said it's something wrong with T-Mobile.
Phone, all streaming services appear to work as normal. None of these problems happen on any other wifi network I use.

If you want to verify the problem is with your T-mobile gateway go to your nearest favorite coffee shop and confirm operation with a different network. Then you have a stronger argument with support for the problem being with their gateway and network. With MS Windows there could be some hidden setting that messes with your need.

If you have one, I would suggest a dedicated wi-fi router that is hard-wired to the modem instead of using the built-in wi-fi. That seems to tax the device a bit too much at times and cause issues like you’re describing. You may also be dealing with an overheating modem.

Thanks Jlillard, but the device is consistent with the sites it refuses to load, so it’s not an intermittent or random occurrence, and I do not think it’s a heat-related issue in this case.
I’d like to continue to solicit advice on this.

I have never run across a scenario where T-Mobile is blocking access to a site. However, since I’m using a dedicated wi-fi router that’s providing DNS for my network as well. You could try hardcoding your DNS servers on your clients to see if that helps. Google’s servers are free to use: 8.8.8.8 and 8.8.4.4. This would help confirm / eliminate a DNS issue.
