Suddenly unable to connect to VPN

I am suddenly unable to connect to my work VPN on my home network (using FortiClient) after having no problems for years. My employer help desk worked with me to troubleshoot - we checked my settings, restarted my computer and network, and tried connecting via hotspot. On the hotspot, the VPN client will connect. 

I reached out to Xfinity to troubleshoot, but the only solution given was to disable advanced security on the gateway. However, I do not have an Xfinity gateway. I have my own equipment - an Arris Surfboard and Google mesh system. 

Today I am also noticing that my connection seems very laggy. A speed test shows 128 up/33 down over wifi, but pages are loading very slowly and videos are unwatchable. I have quit any extraneous applications and restarted my computer, to no effect.

I have issue now and my company has given me two laptops(running Windows 11 pro)and both drop my VPN in maybe 3 minutes or may take 10 min. Even if I just use plain old wi-fi(no VPN connection) it disconnects  and then re-connects. Non-stop all day.  I need xfinity to stop blocking my  FortiClient VPN. I should not have to use my phone as hotspot(it doesn't drop if using AT&T as that will cost me when I already pay over $300/month to xfinity. That will change if not fixed on your side.

Since the wi-fi disconnects, I'd try wired and see if that helps.  (If you have a laptop without Ethernet, you can get a USB to Ethernet adapter.)

Why should I have to go buy something for it to work. Why can not comcast fix the issue. I actually am not the only one with this VPN issue it seems but I'm the one to go out and buy equipment?

Hey there @nfrey, thanks for reaching out through Xfinity Forums regarding your VPN issues. I know how important it is have your work connection up and running! Are you using an Xfinity modem? Do you have a separate router or any Wi-Fi extenders connected?

  I use same FortiClient and was disconnecting and then even my just wi-fi would keep disconnecting. Comcast was no help, they couldn't even see my modem. I found one setting in xfinity app that when I flipped it I have not dropped VPN at all, like not at all.

I also just recently started having this problem with Forticlient vpn. I used to connect without any issues now all of a sudden I cannot connect at all. SYN packets go out without any ACKs back. Using xfinity gateway modem/router. No clue what changed.

Hi there and welcome to Comcast. Thank you so much for reaching out to us here on our Forums page. Are you having any troubles with the Internet when you are not  connected to the VPN?

I am having the same issue. Just started using Forticlient VPN and keep getting disconnected. IT department checked my computer, not anything on my end. Even tried an ethernet connection and was disconnected. I need to work and this is not working. What can you do? Thanks.
