I have seen several posts about VPNs not working with T-Mobile Home Internet. What is T-Mobile's plan to address this? I contacted my corporate IT department and they said it's not their VPN. All wor...

A fix here...hopefully I can help. I have the square 5G Home Internet Gateway. 

 

I was close to modifying the MTU size as discussed in previous posts. Spoke to Ali from T-Mobile Support and he took some time with me.

 

Any speedtest through the Global Protect client was getting .2M up and .2M down. Internal business sites for my work over the VPN performed horribly...wouldn't even come up. Support had me logon to the 5G gateway from another device like my iPad (usually browsing to http://192.168.12.1). Go to Wi-Fi Networks, Logon...Password should be on the bottom of the gateway device. 

Split the wireless network in 5GHz and 2.4GHz. Save the configuration. Then attach to the the SSID for 5GHz. Global Protect VPN worked like a champ. 

Thanks T-Mobile Support!

 

 

I was having a similar issue with the square gateway (KVD21). While my GlobalProtect would connect and I could use RDP (though choppy) and download files from my work computer, the speed was 1/10th the speed of downloading from my Cloud storage with the VPN off.

I tried splitting the network into 5Ghz and 2.4Ghz, and selected the 5Ghz network, but no change in speed or reliability. Then out of a whim I chose the 2.4Ghz. While my overall speed slowed a little, my VPN speed was now only half of my non-VPN speed, and my RDP and work computer connection was stable and useable. Go figure. At least I have an acceptable workaround.
