Laptop disconnects from internet the second it's VPN is turned on
I have a work laptop that needs a VPN connection back into the office, that being said whenever I turn the VPN on I'm immediately booted from the internet and no longer able to connect to anything. If I switch back to my normal router I can connect just fine but with the TP-Link Deco M9 plus for whatever reason, I get immediately disconnected. Very confused on where to go even to check settings, all of the menus are incredibly simple so there's not too much to even look at.
Anyone else had this issue before?
The VPN app if needed is called "Pulse Secure"
