Hi all<br> <br> This has happened two times sinece I installed Hoary on my system yesterday. Suddenly my wireless connection is not working anymore. A screenshot showing the wireless conn. indicator is attached.<br> <br> I tried to solve it without restarting the system by executing the following commands with no success:<br> <br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">behrangsa@Ubuntu:~$ sudo ifup eth1</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Password:</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Sorry, try again.</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Password:</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">ifup: interface eth1 already configured</span><br> <br> This showed that my wireless adapter is already up. Then I did this:<br> <br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">behrangsa@Ubuntu:~$ sudo ifdown eth1</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Internet Systems Consortium DHCP Client V3.0.1</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Copyright 2004 Internet Systems Consortium.</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">All rights reserved.</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">For info, please visit <a href="http://www.isc.org/products/DHCP">http://www.isc.org/products/DHCP</a></span><br style="font-family: courier new,monospace;"> <br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">sit0: unknown hardware address type 776</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">sit0: unknown hardware address type 776</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Listening on LPF/eth1/00:0e:35:78:d7:f6</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Sending on LPF/eth1/00:0e:35:78:d7:f6</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Sending on Socket/fallback</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">DHCPRELEASE on eth1 to <a href="http://192.168.1.1">192.168.1.1</a> port 67</span><br style="font-family: courier new,monospace;"> <br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">behrangsa@Ubuntu:~$ sudo ifup eth1</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Internet Systems Consortium DHCP Client V3.0.1</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Copyright 2004 Internet Systems Consortium.</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">All rights reserved.</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">For info, please visit <a href="http://www.isc.org/products/DHCP">http://www.isc.org/products/DHCP</a></span><br style="font-family: courier new,monospace;"> <br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">sit0: unknown hardware address type 776</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">sit0: unknown hardware address type 776</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Listening on LPF/eth1/00:0e:35:78:d7:f6</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Sending on LPF/eth1/00:0e:35:78:d7:f6</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">Sending on Socket/fallback</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">DHCPDISCOVER on eth1 to <a href="http://255.255.255.255">255.255.255.255</a> port 67 interval 6</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">DHCPDISCOVER on eth1 to <a href="http://255.255.255.255">255.255.255.255</a> port 67 interval 11</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">DHCPDISCOVER on eth1 to <a href="http://255.255.255.255">255.255.255.255</a> port 67 interval 7</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">DHCPDISCOVER on eth1 to <a href="http://255.255.255.255">255.255.255.255</a> port 67 interval 12</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">DHCPDISCOVER on eth1 to <a href="http://255.255.255.255">255.255.255.255</a> port 67 interval 16</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">DHCPDISCOVER on eth1 to <a href="http://255.255.255.255">255.255.255.255</a> port 67 interval 9</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">No DHCPOFFERS received.</span><br style="font-family: courier new,monospace;"> <span style="font-family: courier new,monospace;">No working leases in persistent database -
