Hi
I have F10 running network manager

Both wireless and wireless work fine independently, however when
network cable is plugged in wireless says it is connected (as per
applet) but cannot access any sites .

Any idea what is going on here?

The important issue here is what does the routing table look like. With both connected, run the route(8) command with the -n parameter. Take a look at your route while on wireless only

Kernel IP routing table with Wireless only

0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0

I've seen cases where NM fails to set up the default route.
