Possibe Solution/Work around for Win11 VPN not connecting
Good afternoon everyone!
Came across an issue today and I think I found the problem, and a work around solution.
A few people I have seen have this issue, so I wanted to post my results in case anyone else needs them.
Original Issue: Forticlient (ipsec) VPN not connecting on Windows 11
After some troubleshooting, I found that the VPN would work only over Wifi and not via Ethernet.
I then tested a USB to Ethernet adapter, and it was able to work. So I narrowed the issue down to the onboard Ethernet driver. Driver was up to date, so I did the typical uninstall/reinstall, Did not work. However I knew my Windows 10 machines worked flawlessly.
Solution: I was on Realtek driver version 1168, So I decided to try downgrading the Wifi driver to 10.54. That fixed the issue.
It seems the problem is related to the newest Realtek Ethernet drivers, at least it was for me. I don't know if other brands have the issue too.
I wanted to get this information out there for anyone who needs it, and so Fortinet can be made aware of the issue to look into Driver compatibility problems.
If you have this issue, and this resolves it for you, please let me know, I am curious to see if this fixes for everyone with the issue.
I just registered to also confirm the issue is real, and happens in HP Gaming laptops as well, with Realtek Gaming Gbpe Ethernet Devices, which Windows 11 seems to force updating in Windows Update using "Realtek - Net - 22.214.171.124 (Driver Update)", then we need to revert back every time to previous driver (the one from HP supports download page which is SP111133 for me at least, owning a HP Pavillion Gaming 16-a0033ns). Hope this helps someone too and that this issue is fixed! It seems this is not happening in Windows 10, so W10 with latest Realtek drivers seems to be working, the issue is only in W11! (so strange btw)...
