Has ping / tracert been blocked on 5g network?
Before yesterday (10/17/2022), I’ve always had a command prompt window (MS Windows) up running a constant ping at 3 second interval - so I can tell when the network starts to degrade or just stops responding (which has become very frequent in the last few months).
As of yesterday morning, both ping and tracert commands consistently fail. As in no longer any response. So it appears the ports used for those commands are now being blocked on the 5g network?
I have a 5g phone on Tmobile, and I see the same result. On 5g with hotspot turned on, with computer connected, ping and tracert fail 100%. If I force the phone to use LTE and stay off 5g, ping and tracert start working again. Don't really understand why Tmobile would block such a basic network analysis command.
This is in downtown Scottsdale AZ. As a sidenote, service on the 5g network degrades consistently every day after about 8am, and usually is consistently bad all weekend long. Works great before 8am most days.

I live in WV and started noticing the ping issue rear its ugly head on Friday. I first thought it was something on my network going bad or my ad blocker messing up but narrowed it down to T-Mobile. I'm with everyone else, I can't understand why they are blocking such a critical thing. Glad to see that I'm not alone in the issue.

Please call T-MOBILE and have them escalate this issue.

Hi, I too wish T-Mobile would fix this, and that the issue deserves to be newsworthy!
I have been having major issues related to my T-Mobile home internet, primarily devices like home assistants and their accessories that rely on lower latency to fulfil requests. My Nest Mini now takes on average 10 full seconds to begin loading the response. Beyond that, issues with security since my cameras have increased lag making my doorbell camera less useful, and problems with my DNS not able to properly filter the web. I'm not the only one and neither are any of you:

Clearly this is an aggressive rollout of provisioning. To report my locale, I'm in the PNW but most of you are in the South/Midwest states like Texas. Well, location doesn't seem to matter IMO as I still have noticed many issues recently, to the timeframe given in this forum, in where my web filter has not been able to deny requests properly on one of my home computers. I believe ICMP details noted are related.
Sadly enough, I am JUST learning how to network in college, in my second year and taking classes related specifically to latency and ping... So just wanted to note that I am genuinely affected by this… My own learning material has me doing these types of ICMP ping requests in Windows, and some posts here are lining up with my college material, but while learning from other members here has been fun, it also means to realize that my learning just got a lot harder BECAUSE of my fervent interest in bleeding-edge wireless tech… It doesn't have to be this way!
When testing using Fast.com and other methods, I'm anywhere between 50ms and 1.2seconds loaded for latency. While that hasn't been an issue, what's different is that now never reporting the lower number. One second of latency means I can pretty much throw away my Xcloud membership LMAO I have much better results playing using my phone's mobile hotspot.
Other tests, like Edge's in-browser utility, no longer can report latency at all and therefore the program hangs. Just as another user said, it makes it harder for a given person who doesn't know what's going on understand what's happening. This issue is compounded when the customers end up calling staff who have no source of truth for information on ping/latency leading to no progress for either party.
All in all, this is snowballing quickly and the best action really is to roll back these changes or communicate the incoming fixes. At minimum, progress in this would feel like acknowledging that the official stance isn't that "ping isn't used anymore" by T-Mobile and instead the stance customers want to see would be closer to working on a solution to the existing latency and ICMP problem for T-Mobile Home Internet users Nationwide.
Thanks to other forum members here, I understand now that if I want to continue to effectively filter my web I now need an addition device, a VPN (a hardware solution akin to a PfSense router) between my modem and personal router… and I would rather configure my own hardware like the ASUS modem I had before, but T-Mobile Home Internet does not support other hardware even if I did try and use a hotspot or 3rd-Party 5G Modem. I really don't want a bunch of networking equipment at home, I'd wanna leave that for school lol... so it's horrible to see this provisioning and clearly it's basically "love it or leave it" unless we outcry. So I'd like to join you all in a big +1 @inductivesoul @iTinkeralot @ShanStewart @Walkabt and ask T-Mobile to sympathize with customers, geeks and nerdy students alike and cool it with the way their locking down these gateways. - WalkabtRoaming Rookie
I've been down this path with multiple companies recently. Call centers in the Philippines will never report this up the chain, no matter how many call in. I believe that is where 611 goes most of the time now; I never get Abq call center anymore.
IMO. This would have to become newsworthy and hit a news cycle, or it will be ignored.

1) We have a Ting Fire device that monitor's the electrical wiring of our home and it sends information out. It went offline. Couldn't get it to work, but took the device to a neighbors house and no issues…
2) Had challenges joining a homeowner's association meeting. The HOA property management firm uses Microsoft Teams. I was able to get on after a couple attempts. Microsoft email seems to have quirks sending out emails now too.
3) Don’t know if it is an Apple iOS/tvOS16.1 issue or T-Mobile change issue, but watching services through Apple TV has had streaming services like Disney, Hulu, Amazon say oops, we can’t connect or your are offline, this is sporadic.
Signal strength and quality haven't changed. I check the numbers monthly.
If this were a deliberate decision, T-Mobile may be causing issues with the way other company’s products work.
I hope this is a technical error.
Yeah it's absolutely a T-Mobile issue. I can replicate from and iPhone or Windows computer connected to the T-Mobile home router gateway device. You can test it by opening a command prompt in windows and typing ping 8.8.8.8 and hit enter. You should just get no response in the output. You can replace 8.8.8.8 with whatever you want. For teams it is teams.microsoft.com
i suggest everyone call T-Mobile, maybe if they get enough calls they will take it seriously.

T-Mobile called be back today, they are not grasping the issue. Still having issues with ping but clearly they have no clue what that is. They obviously have no concept of tech troubleshooting and when they read back my issue they get it wrong 100% of the time no matter how many times I explained it to them. They must only have a grasp of English as it relates to the script they have. It is so frustrating. Like I say " This is my issue" they so "I understand, what happens if you try a different website". After literally an hour on the phone with this person I just gave up. My only option is to have our employees change ISP.
I should have recorded these calls for YouTube because it is almost comically frustrating.

Yeah I am not sure what areas are seeing this issue. Sounds like the Bay Area is not seeing the issue anymore. I just tested from the Phoenix area and still seeing the issue.
- mbiermanNewbie Caller
I'm in the Bay Area, CA. I am not experiencing this with mobile service and we don't have T-Mobile for home internet. This discussion makes me glad that we don't. Honestly I don't know what T-Mobile is thinking with this decision.
