Hi Friends,

I have got this issue with Ubuntu 10.10. I have been with ubuntu 8.04 and then decided to try out ubuntu 10.10 .

I booted with a LiveCD and was able to configure the wireless network painlessly using the livecd, so happily I installed ubuntu 10.10.

As soon as ubuntu came up it detected the wireless network and i was able to assign a static IP to eth1 (i dont use DHCP option on my ADSL router) and enter a wap key and use pppoeconf to configure the dialer. The net was on and i was able to surf the net. All hunky dory so far.

However on the next boot the fun started . It did not detect the wireless network. I could not see the network manager icon in the systray. I used ifconfig and saw that the entry for eth1 was missing.

I used ifup eth1 and it said that eth1 was already up.

Then i installed wifi-radar. Wifi-Radar detected the wireless network. I configured wifi-radar for the detected wireless network , set the wap driver as wext and used the manual IP settings. However on clicking connect wifi-radar started looking for a DHCP IP. I cannot understand why wifi-radar is using DHCP when I have specified manual settings. Then I decided to use the wired network to surf the net looking for a solution.

So I plugged in the network cable from my modem , configured eth0 , used pppoeconf and connected the net. Then I foolishly decided to reboot my PC. And wonders of wonders , the same problem appeared.

I cannot see eth0 in my ifconfig anymore. I used pon and it said something about network error or something.

Now my ifconfig shows only lo .Can anybody help me on this.

PS : 1) I tried linux mint 10 and had the same issue . on rebooting wireless network was not getting detected. 2) I have made myself the administrator so that there is no issue of rights or anything.
