Broadcom 43xx not working after updates in Ubuntu 8.04 (Dell Inspiron 1720)

[obloxeon]

I'm running Ubuntu 8.04 and after using the software update, my wireless no longer works. It doesn't connect on startup, it doesn't even show up.

sudo lshw -class network
*-network UNCLAIMED
description: Network controller
product: BCM94311MCG wlan mini-PCI
vendor: Broadcom Corporation
physical id: 0
bus info: pci@0000:0c:00.0
version: 01
width: 32 bits
clock: 33MHz
capabilities: pm msi pciexpress bus_master cap_list
configuration: latency=0

I can get it to work if I go to the restricted drivers manager, uninstall it and then re-enable it, assuming I have a wired connection, but after restart, nothing. I have to do the process over and over again. I wish I never updated through the software updates... how can I get this back to working?

I am in a very similar situation: Dell Inspiron 1545 with Broadcom wireless and I simply can not get the wireless working.

But .... iwlist tells me:


# iwlist scan

eth0 Interface doesn't support scanning.

pan0 Interface doesn't support scanning.

eth1 Failed to read scan data : Invalid argument




Zoinks!!!!!!!!!!


I've been fiddling with this for a few days, no luck


This card was working at one point -- out of the box. I started installing modules, got into a corrupt state and backed off to the factory ISO. Since then it's been iffy -- I had it working for a few days -- when I rebooted the system it went away (so, I never really had the wireless network set up correctly).

If I try to bring the interface up manually I get this interesting error:


# dhclient eth1
...

No DHCPOFFERS received.
No working leases in persistent database - sleeping.
resolvconf: Error: /etc/resolv.conf must be a symlink
* Reloading /etc/samba/smb.conf smbd only
...done.
#


That's Greek to me ... no working leases??

Any help would be much appreciated!
