Wired connection makes wifi fail

[Mark_in_Hollywood]

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

mark@Lexington:~$ ifconfig
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.

Please show the outputs of:

lspci -nnk | grep -iA2 net
lsusb
lsmod
ifconfig -a
cat /etc/network/interfaces
cat /etc/resolv.conf
route -n

Here is the ubuntu pastebin of those terminal responses:

Check the IP addresses, other subsystems:

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

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

Sure this is right?

It is the info in the "Connection Information" of the panel's Connection Manager. I've attached screenshots of the two (eth0 and wlan0) devices.

I'm trying to clarify here. I have access to the internet via wifi. It's a uverse motorola ATT modem. I have a wifi router connected to the ethernet port of my computer. I want to use this router connected to the computer's ethernet port to send the MythTV signal to a "smart" tv's ethernet port. It is not for internet access, except as a way to pass through the 'net to the "smart" tv.

But one thing at a time, first.

Following this post:

I am able to have some ethernet-working and wifi connectivity for internet access, simultaneously.

I can see the following by changing the last octet's digit or digits: example: 192.168.0.1 or 2 or 268 or 10

I can see the control panel pages for

My ISP's modem

My wifi router connected via an ethernet cable

and

SiliconDust's tv tuner

whether I can send the TV signal out from the MythTV through the ethernet cable to the TV's ethernet port remains to be solved.
