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 , needless to say it failed. For the love of god I cannot understand why wifi-radar is using DHCP when I have specified manual settings .
Next 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 , it detected the plugged in connection , I configured eth0 , used pppoeconf and connected to 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 to start the dsl-provider connection and it said something about network error or something . Now my ifconfig shows only lo , both eth0 and eth1 have disappeared. Can anybody help me on this?
Is it a problem with ipv6 , if so how do you disable ipv6 on Ubuntu 10.10 ? OR is this is a known issue with Ubuntu 10.10?
- I tried Linux mint 10 and had the same issue. On rebooting wireless network was not getting detected .
- I have made myself the administrator so that there is no issue of rights or anything.
