>>353215>Some laptops don't like if both wifi and ethernet cable are connected at the same time.But *why*? On all laptops i've seen Ethernet and Wlan are two separate cards, or two separate chips (usually in newer laptops WiFi card is a mPCI/mPCIe card when ethernet is a chip), they have no reason to not work together at the same time!
The thing that you may have seen is a problem with the gateways - for some weird reason, gateway from the WiFi card may have overwritten the gateway from Ethernet, or other way around; What this basically means, is that your computer would try to talk over one interface to an address that is only valid on another interface.
