How can I make a correct /etc/network/interfaces for the following ifconfig output:

eth0 Link encap:Ethernet HWaddr 00:23:54:7e:2e:b6 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:1

I have problem in my Ethernet after upgrade kernel to Quasar8000 2.6.30.8-67.eeepc.fc11. I can not connect to the Internet or open any site with the knowledge that everything is working well and the Ethernet adapter see the connection. the output for ifconfig is:

Code: eth0      Link encap:Ethernet  HWaddr 00:23:54:81:6D:33 

1- I just installed Fedora 12 on my Gateway laptop. It picked up my ethernet card w/o any problems, but it failed to pick up my wireless card. Below i cut and pasted the output of 'ifconfig -a", can someone help please. When you give instructions, please remember that i am new with all this.

[root@irvine etc]# ifconfig -a

Im new to virtualization and for the life of me cannot figure out how to get around this.

I cannot connect to the wireless network at work, athough I have no problems at home. I have connected to WEP networks before, and my wireless functions perfectly well (using Broadcom STA proprietry driver) in most situations.

I wonder if "Interrupt" affects internet connection.
