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/

5g home internet - some sites won't load

I just had the exact same issues the OP had. Have had tmo home internet for 6 months and this is first time it happened. Certain sites wouldn't load, across multiple PCs, phones, browsers, even my roku streaming stick wouldn't connect to certain apps like Hulu, yet HBO Max worked. So definitely seemed pointed to the tmobile service. Yet connecting to my tmobile 4g phone's hotspot made everything work normally. So maybe it was 5g related. The Tmobile home internet app is mostly a joke, basically only things it lets you change if you want 2.4 and/or 5 mhz bands, SSID, and password, that's it. And the vast majority of the time when I open that app it doesn't recognize I'm connected to the modem ("Hmm, we couldn't get you connected automatically...").
After about 12 hrs of having this issue and unplugging modem once to restart with no changes, I was actually able to connect to modem with the home internet app, which I used to restart the device and that did the trick. Back to normal.

Update. Disabling the Google Analytics and SEO plugging on WordPress seems to have resolved my immediate problem. Root cause still undiagnosed.

Disregard my last on the 2.4 GHz connection. Soon as I sent that, my connection went sideways again. I'm going back to my old Nokia gateway from t-mobile. I can't hook up an antenna, but at least I never had this issue with it.

Try taking your gateway's wifi from "auto" to 2.4 GHz only. This resolved the same issue for me. For reasons I won't bore you with I was all set up from switching from the old original gateway to the new white 5G version so I could get an external antenna mounted on the roof. I'm somewhat rural and setting my gateway outside was a game changer for BW to my address. So upgrading to the new gateway was sort of a no brainer. Anyway, having gone thru the issue of setting up some thermostats that don't use 5GHz wifi a week ago when I received the new gateway, when I started having issues loading websites today, such as costco.com for example, I remembered I had reset my gateway earlier today but forgot to set to 2.4 GHz only. I did that, and voila, costco.com and other sites started working again. Hope this helps someone else. On the app, go to the "network" tab, and click on the SSID, and in the "update network" sub-menu, under "advanced settings", you have a pull down and can select between Auto, 2.4 GHz and 5 GHz. Select 2.4 GHz.

I'm having the same problem. I develop Joomla websites, and the back end Administrator section of two of my websites refuses to load certain assets (CSS, Javascript, images). The issue comes and goes. It happens on every browser on every computer in our house… but outside our T-Mobile Home Internet wifi network, it loads reliably every time.

Problem just popped up for me today. A Web Site I manage won't load. Rebooting the router fixes it but then failure ensues. I'm suspicious that some legitimate cross web-site scripting is causing the problem because I use WordPress with tons of plug ins and the problem only starts when I try to update my content. I'll follow-up if can come to any conclusion.

Everything worked well for me for the 2 months, and now my internet is spotty and I'm having issues with chromium based browsers on my work Mac. If I use Safari web pages load just fine. If I use Chrome, Edge, or Arc (all chromium based) I get this error message:
“Your connection was interrupted.
A network change was detected.
ERR_NETWORK_CHANGED”
I've tried changing my DNS to the free Google ones. Renewed the DHCP Lease. Restarted my computer and T-Mobile modem/router. Connected to my work VPN. Nothing has worked so far. Every once in awhile I'll get a website to load once and then I get the error message again.
I don’t have this issue on my personal Mac.
