For example I did consult on one like this and the poor user had set the IP range of the router to be the same as their company LAN. Nope, that never works.
I have encountered a strange behavior with my networks.
In my office, my laptop is connected to our Domain network via cable (LAN) connection. I normally also connect to an external network via WiFi that I use as internet connection for my virtual machines.
I am using my virtual machines for VPN connections towards some of our customer domains, so I can connect via RDP to their servers.
The external WiFi I have so far used is the device: https://www.zyxel.com/us/en/support/DownloadLandingSR.shtml?c=us&l=en&kbid=M-02417&md=WAH7706
No problem everything worked fine.
As the router mentioned above, is normally intended for use in the field, and has only limited WiFI coverage, I decided to switch to this model: https://www.asus.com/us/Networking/RTAC68U/
But, when I connect to the WiFi on the new device, I can no longer be connected to my domain network via cable at the same time.
I shows that I am connected to a network with cable, but it just shows 'Network 2' 'Unknown Network'. And all domain access is lost (Can not send emails, browse intranet or fileservers).
Do anyone have an idea why it is behaving like this?
