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. 

I have resolved my issue with not being able to connect to my work VPN working from home……VERIZON FIOS!!!

The thing is it works but lagging like crazy, can't don't anything. I use Cisco AnyConnect as a requirement from the company and it has been a disaster since I switched from Spectrum to T-Mobile home Internet since the first week of February. Even after this thread, it seems like they still haven't come up with any better solution. I missed my Teams meetings and deadlines while I am working from home. I am on the brink of losing my job. I will wait until this weekend and if it doesn't work out, might as well get Spectrum back. Very frustrating.

I tried this and it does not work for me.  My OpenVPN VPN connection still does not work.  With my other ISP VPN works fine.  It worked fine with T-Mobile Home Internet with the Sagemcom gateway a few weeks ago.  I assume it's the 1.2AC firmware update that broken VPN.

Ran into the same issue today (Cisco AnyConnect VPN wasn't working) and ran across this forum post. Called into TMobile internet tech support and spoke to someone who was knowlegeable about the issue. He said that this was a known issue for the Sagemcom manufactured routers but not for any other manufacturer. The only ones that he could order to ship to me as an exchange were the same manufacturer, but fortunately a TMobile store near me had a Nokia one that they were able to exchange super fast (I still had the original box for my non-working one). Got the Nokia one set up and successfully connected to my VPN!

I had issues and was told it was because of the TM router not allowing static ips.  I now use my own router and I have not had any issues.

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. After that, 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…. 

I posted this on another thread but am repeating here in case it helps anyone. Here was my situation and how it was eventually fixed.

We've had Spectrum Internet for a few years and everything worked great but they kept increasing the price on us. No problems at all with anyone's access. We switched to TMobile Internet right after Thanksgiving (Black Friday deal) and the modem wouldn't work right out  of the gate. Took almost a month for them ( and 2 SIM card changes + 1 modem change) to figure out that it was a configuration issue on their end. So had the system up and running right before Christmas and it worked great for everyone. But then, right after the holidays were over, my wife fired up her work computer for the first time on TMobile Internet service and right away had the "connection lost" issue every one describes above. She would start up and connect but then, after some time, Outlook, Teams and Edge would all show as disconnected. She could switch to another router or even ethernet and this would temporarily fix her connection but it would always come back. I had been working in the meantime on my work computer without any issues on both the Spectrum and TMobile networks. I tried all of the fixes mentioned above but none of them worked for her. Finally got another modem, plugged in the old SIM card and voila it worked immediately. There were 2 other symptoms of this that also went away - my Ooma VOIP system reconnected (it had been flashing red for weeks) and my Ring cameras stopped acting flaky when trying to view video.

Here are the OLD (non-working) and NEW (working internet) modems. So looks like its a modem issue

thanks for sharing. how did you manage to get them to give you the new (white) modem? Is the new gateway name Gateway 5G T-Mobile (G4AR y G4SE)?

Edit: I called T-mobile customer service and asking for modem exchange. The rep says I can't change to a different model and can only switch a different same modem. He put in a ticket for the VPN issue for me to see if they can resolve it.

Thanks in advance.
