Oh, I also have the T-Mobile home internet router and ping is blocked for wired and wireless devices connected to the router.
I have been battling with this for months in the Phoenix AZ area. My other phone is AT&T and they are also blocking ping/trace.
I am honestly surprised no tech blog or YouTube channel picked up T-Mobile blocking ping. You would think it would be newsworthy in the tech circle.
If this was a conscious business decision by T-Mobile, shame on you. Have you updated your terms of service to list the blocking of common network monitoring and management protocols as a feature of your service? If it is an error - identify the root cause, fix it, and apologize. Yours Truly, A formerly happy, now very pissed off customer in North-Central Ohio… Yeah that was my thought as well. This couldn't have been intentional, what ISP is going to block a foundational protocol. Ping is layer 3, it comes before transport, so TCP and UDP, but getting their support to even understand the issue was impossible. I am guessing they eventually discovered the mistake on accident probably because a tech tried to use ping.To others on this thread is ping working in your area?
Looks like T-Mobile is now allowing ping protocol in the Phoenix area again.
Hi, I too wish T-Mobile would fix this, and that the issue deserves to be newsworthy! Please call T-MOBILE and have them escalate this issue.
in Phoenix area too. These changes may be the cause of our unpleasant experience recently. 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 absolut
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.
Doh! Missed one rrrrrr mate! Since we'e icking & choosing cucial communication potocols now, I've decided to no longe suppot the lette 'r'. LOL, right. Yeah, I really hope the tire 2 tech didn’t know what he was talking about. You would think T-Mobile business support would have more information or use a more seasoned rep but they had no more information than regular consumer support. He said he sent the ticket to engineering and it would be a few days.
Ok, i spoke to T-Mobile tech and they said they no longer support ping so that is interesting.
T-Mobile started blocking ping and trace route. MS Teams requires ping as a test before it will connect.
For some reason it appears T-Mobile is blocking ICMP traffic. Both the ping utility and trace routing use ICMP so it pretty much breaks both. Here in east TN now nothing when pinging. Ten packets sent zero responses. The other day the latency was 180 ms plus and 80% loss. Now nada Yeah, 100% loss for me for any webpage. In the Phoenix AZ area.
Here in the S.F. Bay Area I had a similar ping problem for about a week -- about 70-80% lost packets. Starting two days ago, I’ve had no problems. Tried half a dozen sites, all respond with 0% loss. Hopefully the issue gets resolved where you’re at... Glade to hear your issue was fixed. Was worried they changed something. Knowing it is a technical issue that will be resolved is better.
I tried calling T-Mobile support but no one understands the issue or even knows what ping is. Not to mention as a network admin I use apps on my iPhone all the time to ping our external services when I am not near my laptop.
Yeah we have probably 5 users that have reported issues with Teams connecting since yesterday (probably started before on the weekend). After looking at it found they all have T-Mobile home internet. I also have T-Mobile home internet as a second ISP. Cox works fine, ping fails on T-Mobile.
This is really bad. This breaks Microsoft Teams among other services I am sure. MS Teams requires ping to verify connectivity to work (pings teams.microsoft.com). If ping fails then Teams will go offline. Ping fails from my T-Mobile router gateway and from my T-Mobile phone.
