ADSL+2 settings
Hi
First:
Code:

Ubuntu 10.10 x64
ADSL modem:
Buffalo AirStation WBMR-HP-GN ADSL2+ Wireless-N Router High Power
I use and still do the LAN cable to connect t he modem

I had the TD-8811 TP-link ADSL modem and I use (still use) Bridge mode and a ADSL connection via network manager to connect to INTERNET
OK!
when I had Tp link it was just an adsl 2+ modem but this new one is adsl and wireless router as well
for tp link I had to connect to wired connection (which is by default shown in network manager wired connections tab after fresh install ) to be able to go to 192.168.1.1 (modem IP ) to set the settings and it worked fine.
but now with this modem I was able to go to 192.168.11.1 (IP for the new modem it is the factory manual) by creating a blank new wired connection and go to setup page for new one.

and the stange thing is that the privous wired connection (Auto eth0 ) which has the mac address setting in it does not show in the list of connection any more)

and if I put the mac address in the new connection this one will disappear too.
now look at my ifconfig -a

you see the first which is eth0 and its mac address if i put that in wired connection setting is shows in the list but not able to connect if I put the second mac address which is eth1 it does not show in the list

if my adsl connection is active it is not possible to connect to 192.168.11.1 and i could not have the eth connection so what should I do to conecct to 192.168.11.1 and change my setting?

help needed badly
