TMOBILE? VPN? Work from home issues

Been having the same for my wife's work connection thru GlobalProtect.  Between Outlook, TEAMS, etc, one may work or the other.  I have a Linksys Velop plugged into the Sagemcom.

I just did a factory reset of the Sagemcom. The phone app started the setup process. When it got to the part where it asks is it updating the firmware, I closed the app. I'm trying to avoid the update.  

We were still having trouble with the connection thru the Linksys, so I switched it to passthrough, now everything connected. 

I'm in NO WAY an IT person.  Just been taking advice from this thread and others. I have no idea how my Linksys is still working thru the wired connection to the Sagemcom since the factory reset.  I thought I would have to re-login to it, but it works.

We'll see if it continues to work.  I will update if anything changes. For now, I'm not going to touch anything, namely the Home Internet app. Hoping it doesn't start a firmware update. <crossing fingers>

I had the same issues w/GlobalProtect and Sagemcom modem. I setup a TPLink router and adjusted the MTU value to 1300, it still did not work. I could connect to GlobalProtect, but could not access any sites (internal or external).

I called T-Mobile support they knew about the issue and the tech suggested I go to the T-Mobile store and swap out the device. The guy at the store knew the issue as well and gave me an Arcadyan modem as a swap. 

I setup the modem and used the internal wifi on the modem for my initial testing and I had the same problem, I could connect to VPN but once connected could not get any sites to load. Then I connected the TPLink router with the MTU value still set to 1300 and that actually resolved the issue. I was able to connect to GlobalProtect and access internal sites successfully. If I bypass the TPLink router and use the T-Mobile wifi I have the same issue again.

TLDR; had to swap Sagemcom for Arcadyan and still needed a router setup with MTU value of 1300 to get things to work as they should. Hope that helps someone else with same issue.

Until a couple weeks ago working perfectly.  My wife and I work from home and are now unable to connect to our corporate VPNs.  Needless to say if this issue is not fixed very soon we will be canceling our T-Mobile home internet.

I did a factory reset on the Sagemcom.  It did not help.

Called tech support today.  They mentioned there was an open ticket on the VPN issue.  At least there is that.  Support said all they could do is request that I be sent a replacement gateway -- they have no control over what model I would be sent.  They said they have no way to check the inventory of the stores.

After the support call I called some stores.  They only had  the Sagemcom in stock.  One of the store employees mentioned that I could only get the Arcadyan model through "corporate" -- not the stores.

I implore everyone with the VPN problem to call support and let them know.  The more people that call, the more chance we have of getting a quick fix.

What a disappointment… 11 months not a single issue with TMHI and my VELO Cloud VPN. Now without notice TMOBILE yanks the carpet out from underneath anyone who works from home with a VPN and will

most certainly lose their business. It's an absolute deal breaker. Your customers livelihood depended on you TMOBILE, and there is no sense of urgency to remediate. 
 

VERIZON home internet works with corporate VPN's. Watch the migration…

My experience with TMHI has be FANTASTIC for over six months….up until early Jan. All of the sudden I can't stay connected to my work VPN (Cisco AnyConnect & Secure Endpoint). Took the Arcadyan modem into the office and had the IT guys connect to it and try and access our VPN and no dice -- same issue.  I've heard TM issued a firmware update that caused the problems but not sure. Can't believe I'm going to have to dump a cheap, fast, reliable internet service because TM doesn't play nice with a VPN. If anyone has a work around, I'm all ears.  

I talked to Support and they would not send me a new modem.  Said if they did a warranty that I would get the same Sagemcom.  They said I could try and take it to a store and see if they would swap it for me.  Going to try and reset the modem.

keep calling the Tech service. Tell them that other online customer was able to fix the VPN issue by exchanging the modem. VPN worked for me once we switched the Sagemcom.

We’ve reset the gateway (factory default) and things are working again.

TMobile is arranging for me to get a replacement “Arcadyan” model device.
