T-Mobile Home Internet & GlobalProtect VPN | Resolución

If you have a VPN issue, specifically GlobalProtect, I think I found a fix that has been working for me with T-Mobile Home Internet.

Tldr; Set your T-Mobile Home Internet  Wi-Fi Network name to automatically connect (so it connects when you turn on your PC) and under properties change the Network profile from Public to Private - viola. GlobalProtect VPN now works for me, so I can now assess whether I will keep Comcast or T-Mobile. Decisions lol

Fondo: My current provider was Comcast and my rate is $50 with "Promo", ebill, and Autopay for their Blast! Service. I use my own equipment (Moto modem, eero Wi-Fi 6 router) - no issues. The agony/anxiety of having to call them every year when your promo ends and your bill goes up, you threaten to leave, they say they have the same price but for lower speeds, you don't accept, then eventually they keep you at the same rate and speed - after several years of this same rodeo it is annoying.

Presente: It's my 3rd day of having T-Mobile Home Internet. With Comcast I was getting anywhere from 200 -300 Mbps. I get the same or better speeds with T-Mobile, hitting as high as 465 Mbps and 30 on Upload. In short, the speeds at their lowest thus far, have been the same or better. I appear to be on Band 66 which gets me the best speeds in my location and Band 2 still fast but I do see a speed decrease. Unsure if/how the Primary/Secondary connection are at play and if I'm taking advantage of 5G. The first evening was cool, until the next morning I tried to connect to my work VPN and couldn't. When I called that second day, the rep opened a ticket to backdate my software to .0168 stating this was a temp fix for VPN issues - well later that day I noticed the firmware version dropped - so I tested with Ethernet cord and it still did not work. I tried 3 resets, rebooting and searching online for self-service to update my firmware - no dice- faux pas - had to call back in to request they update to latest firmware as speeds were still good but I noticed a difference in the firmware versions. At this time, still waiting for the "push" smh to go back to .0178.

In the past, with Comcast, I did not want to run an Ethernet cord so I would use my Wi-Fi seldomly- I could always connect to the VPN but if I could access the sites was hit or miss, then magically I plug in the dumb Ethernet cord and it works. So, I did the same with T-Mobile, read all the forum thread post on possible causes and fixes. Well accessing the MTU or Ports or whatever else is not something I could do, nor do I think it should even be this difficult between IpV6 and 4 - if 6 is the future then let it be! Anyways, so I was contemplating a return because if I can't use the VPN whose gonna pay my bill?

Based on what I have read, unsure if it’s the VPN provider, your companies own IT limitations protocols, the type of Internet connection required for the VPN to function, it seems like all are valid depending on your VPN, settings, and the ISP provider.

So anyways, I really would love to have 1 bill and get rid of Comcast. So, because of the error or patch issue I would get if I turn on my work PC and it is not connected to an Internet source (Ethernet or Wi-Fi) it gives an error. I used to manually connect to Wi-Fi because when we changed VPN's it was hit or miss, so I changed it to Automatic connect to network. GlobalConnect logs in but I can't access data or my work sites, or even Google.com, I can open Outlook though lol -so I had an epiphany.

I changed the setting, so it connects automatically AND I went into properties under the network name and changed the Network profile from Public to Private - then magically everything worked just fine!  Smh - so is this the missing link with GlobalProtect VPN? Or my companies IT protocol for Wi-Fi? Either way 3 reboots later, I've tested, and all is well, so glad I don't potentially have to cancel T-Mobile Home Internet, or run an Ethernet cord in my home just to work - will continue to test.

Now My Comcast ping ~10, with T-Mobile its ~25-45 - not a gamer so it doesn't concern me. I noticed when I do a speedtest on my work PC connected to VPN(via Wi-Fi of course) the ping was 54 and Dl was ~60-75 Mpbs - versus my personal PC on the same network was 27 ping and 399 - 465 Mbps down LOL . I have not and will not try Ethernet with the VPN anymore as Wi-Fi seems to be working and my work space is neat like I like it…

    I had no issues with my t-mobile home wifi connecting to GlobalProtect VPN for over a year until recently. TMO tech support advised related to firmware update and to switch out router with a new router that would not have the firmware update. This did not resolve my issue. Called TMO tech support again and was advised to create a new network on my TMO Internet App. This temporary resolved my issue for one day, the next day same issue occured, created another new network and this worked again but was only a temporary fix. Following the guidance from GlobalProtect author to lower MTU assigned by your company was tried. My IT Network Support where I work lowered my MTU from 1500 to 1300 and this resolved my issue and I could reconnect using my original network assigned on my TMO internet app. Seems to be related to the WIFI type of device from TMO as the type of device usually requires lower MTU settings in order to operate correctly. Hope this helps other users experiencing the same issue. I am happy to report my issue has been resolved and I can continue to use TMO Home Internet which is my preferred carrier of choice :)

    I have been experiencing the same issues and have tried so many things to get my connections working again. 

    Did you adjust your MTU settings on your computer or your router/internet?

  • I have also been experiencing g the same problem as vivana808, but adjusting my computer’s MTU setting seems to have fixed things for now.

    I am wondering what T-Mobile is doing to fix the problem. KJW2574 asked the same thing above.

    My problems started at the same time as heavy rainfall and flooding in my area. Could these events be connected?

    Reducing the MTU to 1300 did work, however!

    See this thread

    I have tried setting a static IP, changing IPV6 to local-link only, MTU to 1300, nothing is fixing the issue.

    I connect just fine but then cannot RDP or connect to any internal web-apps or pages
