VPN issues, some work related programs won’t load

I'm using the Sagemcom Fast 5688W. I've had no issues since staring with them last April until January which seems to coincide with the 1.2.AC firmware update. Last week I was told that model has a known issue with VPN. Today I given the impression, by a rep, that it is more of a T-Mobile problem and not just with the Sagemcom and to try the Arcadyan KVD21. If that doesn't work find another ISP. I'm using Cisco AnyConnect which I think is pretty common. How T-Mobile has problems with their gateways and AnyConnect is not very assuring. Fortunately I have at least 3 other ISP options at my house, not a luxury most people have. I am also able to hotspot from my work phone but that is not a good long-term solution.

Can you tell me what the model of the different gateway is? When I asked yesterday if there was another gateway to try, my customer service rep told me there wasn't.  I hate switching because it's cheaper than what I had before and faster. However if I can't work from home when needed that doesn't help.   
thanks for your comment! 

Hola,

You’re welcome. I was a little hesitant to post because I’m not sure this will work.

The model number is KVD21. And the HW version is R01.

So far so good this morning. But again, since the problem is intermittent, I'll have to give it some time to see if this really does work.

I had the same issue with VPN 3 weeks ago. It resolved but came back last week. I had tried everything from my company IT people. I called T-Mobile and the rep told me that there is a known issue with the Sagemcom and VPN. They are working on a fix but had no timeframe. I asked about changing my gateway to another model which is an option but only the Sagemcom are at local stores for me.

I've had this same problem for a month now. My IT department couldn't help and after reading about the problems others were having, I realized it WAS my internet service provider. I've tried resetting, rebooting, and other solutions that I could find in this forum and online but nothing has worked consistently. Still had intermittent problems. Then this morning, my gateway had an error code saying there was something wrong (no kidding!). Finally, called again this morning and the customer care technician said that he was aware of the problem and the only thing he could offer was that I could swap out my gateway for a different model. To his credit, he did find a model different from the one I originally had at a store that wasn't too far from me and helped to coordinate the swap. It seems to be working for now but I'm still wary. Will report back to let you know the results one way or the other.

Hope there is a solid solution soon. For everything else, T-Mobile works great. However, it's the ability for me to be able to do my job in a reliable and consistent fashion that is the most important.  If this doesn't work, I will have to switch to a different internet service provider.

Called TMOBILE this morning; they said a resolution still wasn't found to fix the issue. Instructed me to check with my IT department to change VPN, I work for a power company they aren't going to just change something because TMOBILE can't get their stuff working. Promptly told them to send me a return label for their box and cancel my service; hate to since it is faster than what I did have but what I did have at least worked with my work computer/vpn.

Thank you. I'm out as of today. Checked here one more time before calling AT&T to get internet through them. I cannot tolerate another minute of T-Mobile not having corrected this. Actually I'm giving them one more chance 1st and calling to see if I get one of the honest and decent reps to find me the correct modem needed. That IS the only fix other than moving on to another company. 

Can also confirm I can no longer connect to work VPN's, started happening about 20 days ago as well. I've tried every suggestion online, with changing MTU, 2.4ghz, nothing really works anymore. And its not just exclusive to T-Mobile Internet users, it's happening for me on my iPhone Hotspot.

If I get assigned a 169.x.x address, it works fine, if I have a 172.x.x address, it does not. That is the only correlation so far that I have noticed when it sometimes works.

Exact same situation here. Last week was the storm. Everything was working perfectly fine then the day after the storm, VPN is an issue up to now. T-Mobile rep is no help. 

Tried the suggestion:

2.4 GHz, and select WPA - Did not work for me 

2.4 GHz band > select WPA/WPA2 > WPA “TKIP & AES” -  Did not work for me 

 

I might end up switching Internet promptly because it's an issue especially when you work remotely.

I’ll search around if I can find other tips 

Didn't work for me either. And, no storm involved. T-Mobile did something w/ their network and ended up F'ing many of us who work from home. It's most definitely on their end. Take from someone who's already been there, done that it has nothing to do w/ your work VPN.

Hola,

I can now use Cisco AnyConnect.  Is this resolved?

No.
