Same issue. VPN disconnects from WiFi on work computer
Hello,
iv have had the same issue posted on this thread. My VPN constantly disconnects when working on my computer…. I notice this because I only need to connect to the von when working on my work computers the connection is very strong (600mbps or more) and IT has determined it is not the VPN after many tests. There a Xfinity related issue that I do not know how to solve. Can someone please sheds some light on this

Have you edited your PC's network adapters to use public DNS servers like 1.1.1.1 and 8.8.8.8?
Do you lose all internet connectivity or just connectivity with the VPN?
Have you tried to hardwire directly to the modem and see if the issue replicates?

I have been having the same issue as well, My xfinity modem is an XB7 with firmware TG4482PC2_6.3p15s1_PROD_sey.
All of my other devices that are connected to the xfinity modem that are hardwired or using wifi (not using vpn) work perfectly and there is no issues. I only run into frequent disconnects when using my work pc which is connected to an aruba remote access point which is what is handling the vpn connection. My company’s IT has troubleshooted the issue over several days and has even tried replaced everything (computer, cables, access point) but nothing seems to work. I have also tried Port forwarding all vpn IPsec related ports to the Aruba RAP (500,4500,1701) in both tcp and udp. (Did this on the xfinity modem)
Disabling advanced security in xfinity modem.
Dropped firewall level to custom in xfinity modem (nothing checked). None of this has helped, The vpn connection still continues to drop about 10+ times an hour making it impossible for me to work.
My company’s IT told me that this seems to be an issue with my isp since they have determined that I am Experiencing IPSec packet loss. I have also narrowed this issue down by taking my whole work setup to another home that uses a different isp for internet (blue stream) and I did not experience any disconnects while working from there using the same setup. I am really trying to make this work with my xfinity internet but I may just have to switch Internet providers if I can’t find a permanent solution.

Same issue here as well -- VPN service dropped and cannot reconnect. Company IT has said as of this morning they have six clients calling with the same issue all using xfinity and not being able to access their companies VPN servers. Please fix or we will all have to find new isp's!

To whomever this may help,
I finally got my issue fixed, I'm not quite sure what exactly fixed it but I did what XfinityXanadu suggested and used public DNS servers so I decided to try out the CloudFlare DNS servers which would be 1.1.1.1 for Primary DNS and 1.0.0.1 for Secondary DNS. I could not edit the DNS servers on my work pc network adapter since its locked down and requires an admin account to access and edit network adapters so instead I connected a 3rd party router that I had to the main comcast modem and modified the DNS entries on the 3rd party router since the DNS entries on the comcast modems are static and cannot be changed (I went in and tried changing it but it is greyed out and does not let you edit the DNS). I connected my work pc to the 3rd party router and now I no longer have any issues when I'm on VPN for work, I have a good connection and I am no longer experiencing the frequent disconnect while working on VPN from home. The reason I say I'm not sure what fixed it is because maybe just using the 3rd party router did the trick or if it was both the 3rd Party router and editing the DNS, Another thing to note is that both my comcast modem and the 3rd party router have DHCP enabled but since my work pc is hardwired into the 3rd party router its obtaining its ip address from the 3rd party router and not the comcast modem. I didn't want to further troubleshoot to see exactly what fixed it and mess up something I struggled so hard to fix. I hope this helps someone because I almost lost my job because of this. Comcast/Xfinity really needs to address this issue and pinpoint what exactly is causing so much trouble when using a VPN. Many of us work from home and we need a permanent solution for this issue and not a Band-Aid fix.

Same issue here.
Connection to work vpn had worked for over 4 years then last week just stopped connecting.
I can connect to work vpn with phone Hotspot and any other network besides my home network.
Called xfinity over the last week and they have been zero help. They say is my works vpn configuration causing the issue.
I switched my 3rd party router from access point mode to router mode then put xfinity modem in bridge mode. This fixed my issue for two days then same issue happened.
I reset xfinity modem again then changed default DNS to 8.8.8.8 on my 3rd party router and confirmed xfinitys standard defaut gateway was not being used. I have connection again. Let's see if that lasts more than 2 days.

I am having this same issue starting a few weeks ago. I am looking for a new Internet provider because I do not have this issue using my work laptop as at other people's houses that do not use Xfinity.

I am having the same issue with only my VPN dropping after Xfinity was out doing work in our neighborhood since Friday. I can connect to my VPN just fine with my mobile hotspot but not via Xfinity’s WiFi.

Many people in my org who use Comcast recently started to open tickets about VPN drops. When they switch to a mobile hotspot or use a different WiFi network they have no drops. Is Comcast doing something about this problem?

I am having the same issue as well. I would say the disconnect and reconnect started a couple months ago but has progressively gotten worse. Sometimes my work VPN disconnects and reconnects every 10 minutes. I restarted my modem and am now on a new laptop and the same issue keeps happening. We also upgraded our service to make sure we had enough WiFi power to keep up with the household demand and me working from home so this should not be happening. What is the resolution for this issue? None of my other devices have disconnection issues but it doesn’t seem to support my works VPN anymore. Xfinity, Please help me get this fixed. I’ve done all the suggestions with no resolution.

I have been experiencing this issue as well, all day long the VPN disconnects, logs me out of work and I have to log back in to everything, only for it to drop again, ridiculous. I am going to have to speed up my moving plans so I have better internet options, very frustrating!

I too have been experiencing these exact issues. I have a work laptop connected to wifi and VPN is disconnecting/reconnecting multiple times an hour throughout the work day. It started doing it occasionally and has progressively gotten worse over the past several weeks if I had to guess. Yesterday, I connected my laptop to my modem via an ethernet cable. In my short test yesterday (a couple of hours) it worked well. If connecting with an ethernet cable helps, does it mean a new modem would not help resolve this issue? I can't have ethernet cables running throughout my home to my modem so I am looking for a solution to use wifi for my work laptop and not have VPN disconnecting constantly. On a side note, I do think I need a new modem regardless as I have been having unrelated issues with other wifi connections, e.g., home PC, Roku, etc., but no issues with our cell phones.

I have the same issue as above. Xfinity I need help desperately. My IT department gave me some questions to ask about to. Everything else in my home works well other an my work desktop, The VPN drops several times an hour and an ethernet cord has been just as worse. Can someone from Xfinity please contact me. It's extremely frustrating as I work for a remote company.

Same problem with VPN here. I've spent hours with Xfinity tech support (which has been absolutely infuriating and not helpful). They love to collect a lot of data, but provide no useful information and resolving this problem.

I have been having this issue for about a month. I am a hybrid employee and I have had to go into the office to work because working from home takes twice as long due to this issue and the benefit of working from home has gone right out the door! I have had tried all the troubleshooting that everyone else has tried and our IT department has tried several things as well and it continues. xfinity needs to reimburse me for my internet that is not working, gas for having to go into the office and pay me OT for the extra time I have had to work. Please get this resolved!!
