Comment 92 for bug 498336

Another data point...

I just finished a network upgrade of my Dell Latitude C840 to 10.04 tonight. Wireless didn't work when I rebooted, although I could see all the access points in my neighborhood. I just couldn't connect.

Doing #86 above worked for me after a couple of reboots, but only once so far. I went for a complete shutdown and reboot. It didn't work after the first reboot, but it did after the second reboot. Now it's not working again after five or so reboots.

Here's something freaky:

% dmesg | grep eth
[ 56.182927] ADDRCONF(NETDEV_UP): eth1: link is not ready
[ 56.560831] eth1: New link status: Connected (0001)
[ 56.560901] ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
[ 57.247326] eth0: setting half-duplex.
[ 57.247647] ADDRCONF(NETDEV_UP): eth0: link is not ready
[ 57.365098] eth1: New link status: Disconnected (0002)
[ 57.788498] eth1: New link status: Connected (0001)
[ 57.793937] eth1: New link status: Disconnected (0002)
[ 66.636059] eth1: no IPv6 routers present

I also tried sudo dhclient as suggested in #91, but it couldn't ping the router.

So, it worked just once. I fired up a browser and looked at a few pages, then I rebooted, and now nothing.
