Wired connection makes wifi fail
I get to the internet via wifi. I share it with my neighbour (his idea). I'm trying to install LAMP and have a server for my .com. I'm trying to get MythTV to work.
I have set a static IP address using NM
eth0 Link encap:Ethernet HWaddr 40:61:86:06:56:14
inet addr:192.168.0.101 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::4261:86ff:fe06:5614/64 Scope:Link
wlan0 Link encap:Ethernet HWaddr 90:f6:52:0c:2d:a4
inet addr:192.168.1.73 Bcast:192.168.1.255 Mask:255.255.255.0
when the eth0 is connected, I have no internet access. What do I have to do to not lose internet access? Does the WiFi have to drive through the router? How do I do this? Please point me towards a Tutorial or How-To.
By the bye: As I write this, the eth0 is disconnected.
