My company uses Cisco AnyConnect VPN. I've been having all the same issues mentioned in this thread and gone down the IT rabbit hole trying to remedy this issue. Finally found a knowledgeable T-Mobile technician that explained if personal or work VPN or systems are operating on IPv4 then you need to go into your T-Mobile home internet app > select network > click "+" to add network > name network > create password > select 2.4 GHz band > select WPA/WPA2 > WPA "TKIP & AES" > then save the new network and connect. Worked out my VPN issues and my security cameras are working now.  

My wife's company uses Cisco AnyConnect as well. I tried your solution, and it is currently working. Thank you. For the record, I also work from home and am using SonicWall NetExtender without any previous nor current issues. We have the old black tower modem, and I'm going to try to replace it with the new white square one per another user's recommendations in case this solution turns out to be temporary. This has been a very thorough and interesting thread to read. God bless you all.

Cue the South Park bank teller "Aaaaaaand it's gone!" Solution stopped working after a half hour. Ordered another modem (representative said he could not specifically choose which type of modem would come. He says all of the hardware is identical inside of the different models, and people have been reporting issues with all of the models, apparently. If this new one doesn't work, I'll be getting internet elsewhere, unfortunately.
