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-FiAnd 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…https://dcltesting-2.com 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…http://judiglova.com/

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!

5g home internet - some sites won't load

I don't think is DNS issue, I have programed and used multiple DNS servers to overwrite theirs and that didn't work either. I think is more routing issue within T-Mobile Network.

I don’t think, people should turn off IP v4 or V6 or make any changes for using the network, it should just work out of the box for all website not just some.
People should post links that they have problem accessing so T-Mobile can look into the issue, I bought one and I had to return it because I wasn’t able to access certain websites over T-mobile network, they were not even accessible over T-Mobile Cellphone plan either.
those links were not bad links, they were Gov. websites. for example one was “https://passportstatus.state.gov/”

Anyone from T-Mobile monitoring this thread or they don’t even care?!!

Here is what I learned messing with this almost all day.
When I unchecked the Internet Protocol Version 4 (TCP/IPv4) and then hit OK, under the Wi-Fi went from 'Unidentified network' to my 'actual wireless network name'. But when I did this, and then connected back to my hotspot, I was not able to connect to a website. When I went to the Configure, checked on Protocol Version 4, hit okay, I was able to go to the website.
This is some frustrating mess. All my other devices work fine. I get this new Lenovo laptop and can't even get on all necessary websites.

That might be a DNS resolution issue and stale cached data issues. With out packet captures and analysis it is just a guess. I hope this helps.

If the software for that router will let you change the DNS resolution use Google or Cloud Flare. It might be a DNS issue. Try setting the DNS resolution on your client first. Don't allow the client to obtain DNS from your router. I use a set DNS resolution on clients at times as such. I run MacOS and Linux primarily and only have a single MS10 client for my wife. If it is a Windows 11 thing well I have moved on and ignore Microsoft now. Not going there. I have no such issue with my clients but I also have the original Nokia gateway router and it works great for us. It might be a software issue with the gateway router.

I had the same problem again this week, couldn't connect to my company's website or the University of Utah's website. I rebooted the T-mobile home internet gateway and they both worked. I'm not going to be a T-mobile home internet customer long at this rate.

Had the same issue with a brand-new laptop! I was able to access some websites, but not others. Amazon worked, Ebay did not.
I did the following steps, saw my TMUS network name pop up.
go to network connections

right click on the TMUS wireless. go to your wireless properties, click on configure.

go to advanced tab. click disable on the 2.4 Gz value.

select the 5G wireless.

I finally saw my TMUS name.
This fix was short lived. After a while it went back to not connecting to certain websites and Microsoft store :-(

This is a big issue that T-Mobile has to address. resetting the device is not a solution. they need to fix it before they can go prime time… this very annoying to the user.
I’m in IT myself and this can’t solution. i think they have major Routing issue within their network too.

My wife's connection to where she worked was vary sporadic. Sometimes things worked and sometimes they didn't. Some things worked - some things didn't. The company my wife was working for said it was because they are IPv4 only and T-Mobile is IPv6 only.

IPv4 may be one issue, but it is not the only issue preventing users from going to a domain. As I mentioned in my earlier posts, after initially resetting the gateway, I could connect to my company's website and e-mail servers. A week later, my company's website and e-mail servers stopped working from the T-mobile gateway but worked using T-mobile 5G on my phone. After unplugging the gateway for 5 minutes and restarting it, my company's website and e-mail servers could be accessed again from the gateway. T-mobile seems to be blocking some domains using the wireless gateway, but I don't understand the erratic nature of the domains working after a reset or restart of the wireless gateway.
