Hi,

I've been struggling to get a comfortable wifi setup on my via epia mII mini-itx system for some time now. My current problem is as follows, trial and error trauma in chronologocal order.

1. Tv card is set to 192.168.0.1 on mythtv-setup by default, this appears with 'static settings' under sit0 in the /etc/network/interfaces file

2. LAN router is at 192.168.0.1

3. I am using ndiswrapper for wifi

4. Tv works

5. If I setup my wifi card as per...

ifup wlan0
iwlist wlan0 scan
iwconfig wlan0 essid NETWORKNAME
dhclient wlan0

... then I see 192.168.0.2 successfully registered as the LAN address for mythbox on ifconfig

6. However, even though it says "bound to 192...etc), wireless doesn't actually work, if i do ping www.google.com i get nothing

7. The same thing happens if I have eth0 identified in the /interfaces file (even though not physicall connected). It is as if wlan0 only works if it is the only registered device in the /interfaces file (other than lo)

8. This can be solved by commenting out the sit0 static settings on the /interfaces file an then repeating wifi steps above.

9. However if I do this, then Tv doesn't work. I get - "the mythbackend is not running..check the IP address..etc"

10. If i now do ifdown sit0, and then do "iwlist wlan0 scan" i get "operation not permitted: wlan0 doesn't support scanning".

11. I then realised LAN and sit0 are both on 192.168.0.1, so I changed sit0 to 192.167.0.1 in mythtv-setup and /interfaces. Now the tv still won't work, but not with the error message - it just flickers for a sec and then returns back to the Main Menu.

12. What exactly is sit0? This wasn't identified on ifconfig with previous versions of KM. I just used to have "lo" for the mythbackend/tv server.

13. Bottom line, I can only have Tv or Wi-fi, not both. I appreciate I don't fully understand what lo and sit0 are so maybe that is my downfall.

14. I have tried using netcardconfig to set my /interfaces file but no solution there.

My /interfaces file at the moment.



Current output of "ifconfig"




Current output of iwconfig



Please help geniuses.

*Warning-limited knowledge*
l0 is the 'loopback interface' and is basically just an easy way of referring to the local machine without knowing anything else about it. So if you frontend is on the same machine as your backend, then you would (by default) use l0 (or 127.0.0.1) from the frontend to connect to the backend.

sit0 is an IPV6 interface. Its there because IPV6 support is compiled into your kernal I think. You probably don't need it.

You may have a default gateway/routing issue?
