Re: Unable to use T-Mobile Home Internet with work VPN, any suggestions?
Jaycam wrote: Same here... T-Mobile for sure did something on the back end of their network 3 days ago that has rendered my Cisco Anyconnect unusable for internal Networked applications. I did some testing of my own this evening and what worked for me was disabling IPV6 on my external router. I had IPV6 pass through enabled for the last 2 years and had zero issues. Once disabled, It made my overall connection seem more snappier as well. Also I would highly recommend changing the DNS to Cloudflare. My guess is with announcing this 1.2TB throttle a few days ago, they are doing everything in their power to crack down on individuals that abuse their Network. It's unfortunate that people like ourselves have to suffer at the expense of those individuals. Hope this helps…. If their intention is to crack down on individuals that abuse their network, blanket banning VPNs isn't the solution. Example; My work VPN uses about 18gb a month. I, on the other hand with streaming services, downloading games on steam, 4k youtube; I use WAY more data than my work allotment does. I think I hit 900gb one month because a gaming hard drive failed and I had to redownload everything. But if my VPN doesn't handshake properly, its slapped in the face and denied. IMO, this was a bad business choice to eliminate VPNS, to avoid IPv4 support and provide even more of a worse tech support. I work tier 2 tech support. Every time I call tmobile, they seem like nice people, but the tech part of the interview was waved.17Visto3likes0ComentariosRe: Unable to use T-Mobile Home Internet with work VPN, any suggestions?
I'm glad I'm not alone in this boat. For me, this started Friday morning 0830 19Jan2024. I have used this service with Cisco Anyconnect and a Meraki z3 for over a year and a half. I have been a Tmobile home internet customer for over 2 years. Its pretty much my only option. If you're told by T mobile to call your company's help desk. You can, but they'll be stumped, all the way up to the network engineers. For context, I'm Tier 2 Help Desk for a hospital network with 25,000 users and I've used Tmobile home internet exclusively for over a year and a half. I started having this problem on 19Jan as I use a Meraki Z3 to connect to my work network, with Cisco Anyconnect as a backup VPN. I know there are threads 2 years old about Tmobile having issues with the Meraki but I personally have not. And I had used it for a year and a half with rarely a hick-up. Everything came to a screeching halt at about 0830 Friday morning. I excused myself from my job to power cycle my devices, thinking Tmobile was slow and power cycle to a new IP. No dice. I lost ALL Meraki connection. Yet the Meraki light showed it was connected.I switched over to my home wifi and connected to Cisco Anyconnect, but the connection was slow. Roughly 10/2 as opposed to 60/10 outside of VPN. I disconnected from wifi and plugged a direct network cable in. NO connection. I overnighted a network cable from Amazon (I needed a 20 ft). Still NOTHING with a wired connection. I then placed a warranty claim on my gateway as it was the old 4g white router. Tmobile overnighted a Nokia (trashcan) 5g router. STILL no wired connection. And slow wifi with VPN. By this time I had researched reddit and forums and all were coming down to the conclusion with IPv4 vs IPv6 address conflicts. 100% on Tmobile's side. But no one at their help desk knew what the heck I was talking about. If I could see their faces, they would probably look at me like I was crazy. I broke outknowledge and experience, and I was shut down like I was speaking a foreign language. The guru on my ITS network team in charge of the Meraki Z3 routers mentioned that send and receive are being sent on entirely different ports and the 'receive'ports are changing, leading to time outs and bad connections. This also affects security cameras like Ring and VOIP phone services. This will affect a lot of work from home people that talk on a virtual phone like Cisco Jabber or a Cisco IP desk phone. This is a SERIOUS issue that is going to drive a lot of people to change service as they can no longer use it for a TRUSTED work from home internet connection. I do hope T mobile scrapes these forums for ideas and user feedback. If not, a lot of people are going to find alternatives; or lose their jobs. Personally, like others; I will be spending the weekend searching for another work alternative. My only other option is US Cellular's home internet. And I'm not impressed with their ping times. If ping times are like my phone (150ms), it won't even do a Zoom meeting. Tmobile was the golden goose that allowed me to live my rural country life while still having a taste of modern internet. This is no longer the case when it comes to my job security.6Visto3likes0ComentariosRe: Unable to use T-Mobile Home Internet with work VPN, any suggestions?
TheLostITGuy wrote: Hi Everyone, Thisis something I posted in another T-Mobile forum a while back. After putting some research into this, I believe I have found a solution (at least one that worked for me). PLEASE NOTE: PART OF MY SOLUTION IS USING MY OWN WIRELESS ROUTER ATTACHED VIA ETHERNET CABLE TO THE BACK OF MY HOTSPOT MODEM. THE INSTRUCTIONS I LEFT BELOW WILL NOT BE OF MUCH USE TO YOU IF YOU ARE NOT USING A WIRELESS ROUTER. This does not require much tech-savviness as I found what I needed from a YouTube video and a little googling on how to access the settings I needed, which I'll post a link to at the end of this. Basically, it's the MTU (Maximum Transmission Unit) settings that T-Mobile uses. You don't really have to know much about this other than how to find out how to change it, either on your computer or on your wireless router (if using a wireless connection). Most internet providers set their MTU size at 1500. This is more-or-less a standard most in the industry follow. From what I found, T-Mobile sets their MTU sizeat 1450. I'm not going to go into explanation on how this works; just know this is the problem. This tiny difference seems inconsequential, but can make or break your VPN connection. Unfortunately, it's on us as the customers to find our own solution(s) to this problem. This YouTube link gave me the information on how to check my MTU settings and change them on a Windows PC. This is a solution specifically for if you want to only change the MTU Size on individual PC's in your home. Ultimately, I did not change my MTU Sizeon my laptop, but the part of the video that helped me find the MTU Size was key to figuring this whole thing out. The link will take you directly a few seconds right before the spot you need to pay attention at begins: I'm not a Mac user and am not experienced with using them, but this is a link for all y'all Apple fanatics that I found while I was searching for a reason for this problem. It was the first article I came across that set me on the path to figuring out how to change my MTU setting. Hope it helps: https://amithkumarg.medium.com/resolved-t-mobile-home-internet-vpn-issue-2f5ca594c23e And, lastly,I use a TP-Link Wireless router. This link is for TP-Link device owners and shows you how to change the MTU Size. There's no way I can find links to all the different types out there. However every brand's settingsareeasily searched on Google, so good hunting to you and good luck: https://www.tp-link.com/us/support/faq/1134/ I hope this helps some people. My issue is (self)resolved. This is old knowledge and he has since reported it didn't work after 45 minutes. Just saving people time.2Visto2likes0ComentariosRe: Unable to use T-Mobile Home Internet with work VPN, any suggestions?

I've been having all the same issues mentioned in this thread and gone down the IT rabbit hole trying to remedy this issue.

Worked out my VPN issues and my security cameras are working now. THANK YOU!!! My company uses the same VPN and it worked perfectly until Monday, 1/22, probably the same change you experienced. I followed your guidance and it works perfectly. I'm back to the same full speed I had previously, maybe even faster, and now I have a second home network dedicated to work from home. Sadly, this fix lasted about 45 minutes. Afterthat, and then after an hour on the phone with TM help desk it has been escalated. I really hope its been escalated. From other threads I've read, escalation doesn't exist and its smoke blown up your….7Visto1like0ComentariosRe: VPN issues, some work related programs won't load
I'm one of the many who has had VPN issues since roughly 19Jan2024. I currently use (or DID use) a Meraki z3 for VLan connection and Cisco Anyconnect as a backup if the Meraki network on my work's side went down. I can no longer connect via the Meraki and Cisco Anyconnect's VPN speed is slow at 10/2 while connected. 80/20 when not connected to a VPN I have searched reddit and these forums, have attempted every work around thus far, and nothing. What ever updates T-Mobile did on the back end better be resolved soon before they start having their users drop service in droves. Work From Homeis still quite popular, regardless of what CEOs want.23Visto1like0Comentarios
