FortiClient on New Windows 11 laptop connects on WiFi but fails on wired network

Hi Team,

Is it happening only on 7.0.5 version, could you please test it with different forticlient versions and keep us posted

I found some older  FortiClient versions. All end up installing 7.0.5 with the same problem 

Good evening,

When you say connects versus does not connect do you mean VPN connection , internet etc? I'm typing right now from a Dell XPS15 running Win11 with FortiClient 7.0.5 on a wired connection. What specifically does not work when wired? Sorry if iImissed that some place.

Thanks

Please check if you have any endpoint control(sophos,symantec, etc) on that Windows 11. In some cases, this endpoint block the interface binding and makes the VPN connection failed. However, i need more information regarding the error. Are you reaching 40% or not. Reaching certain % means different kind of error.

This laptop gets wired connection only with an external USB adaptor. I decided to try several adaptors. FortiClient failed to establish VPN connection with the first 3 adaptors although they all provides stable 1Gbps connection. When I tried the 4th adaptor FortiCliet succeeded! I feel lucky, and now I just worry not to lose this 'special' adaptor...

I am having the same EXACT issue.  The VPN will not connect on a wired connection at all.  The wired connection has Internet Access and Internet speed is 950mbps but when log into the VPN the connection fails.  The wired connection is on my Laptop Dock so I tried a separate USB ethernet dongle.  Verified Internet connectivity and then tried the VPN and the same problem happened.

If I disable the wired ethernet adapter, and connect my laptop with WiFi, the VPN connects perfectly and is happy.  Of course my WiFI is much slower so I prefer the wired connection.

Two other things to note:

When I am trying to connect to the VPN with WiFI, if the wired ethernet interface is not disabled, it will not connect over wifi at all.  It fails like the wired connection.

After I establish a connection over the VPN with WiFi, I can re-enable the wired connection and it works fine.  If I turn off WiFi, the VPN will disconnect, however the Internet is working seemlessly.

Hi We use predominately Lenovo ThinkPad and yes same issue that wireless works but wired either with USB / USB-c/ or dock ethernet not connecting. I pulled out an old Startech USB adapter and it will work. The log file says "No response from the Peer". Fortinet must have a fix for this as it seems to be happening to a lot of other people. 

Has anyone heard of a fix for this?  Has Fortinet posted a fix an an updated client?

Just a little more information, I have two connection profiles, an IPSec profile which is the one I use and is having the problem we are talking about.  The second Profile is an SSL Profile and that DOES connect with the wired connection, and wireless disabled.  So just the opposite of the IPSec.

I have exactly the same problem. All of my users (including myself) on Windows 11, with a laptop and docking station can no longer connect to our IPSec VPN if they have an ethernet cable plugged into the dock. If they disconnect the ethernet cable and use WiFi, it's fine. Some users have reported that a wired connection works using a Startech dongle instead of the Dell dock.

Hello avaknin,

Can you please check whether below Windows Update is installed on your Windows 11 device.
