Lost Wireless WPA2 connection and ability to see USB after update
I'm relatively new to Linux. My netbook ran updates yesterday for Ubuntu and now I am unable to reconnect to wireless network connection. I am using WPA2 encrypted security. I am able to connect via wired LAN.
Also, when I went to connect using USB mobile connection, I get an error "unable to mount location". I get the same error if I try to connect my external CD drive.
I have tried to force mount but no luck. I could use some suggestions!
Thanks for your help.
The point of the last item is that you may need to add a permission line so members of you group can use the mount and umount commands. (The update may have made unexpected changes in the sudoers file. See if you have a /etc/sudoers.save (or similar name) file. Such a file should have been created if the sudoers file was changed.)

I am using Ubuntu 8.04 with Gnome desktop (2.22.3) on a Dell Mini 9.
My wireless device is using Broadcom STA Wireless driver for an 802.11 wireless card
Here is the output from the etc/sudoers file:
# /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for details on how to write a sudoers file.
#
Defaults env_reset
# Uncomment to allow members of group sudo to not need a password # %sudo ALL=NOPASSWD: ALL
# Host alias specification
# User alias specification
# Cmnd alias specification
# User privilege specification
root ALL=(ALL) ALL
# Members of the admin group may gain root privileges %admin ALL=(ALL) ALL
ALL ALL=NOPASSWD: /sbin/initctl emit boot-phase ui-started -n
I don't have a sudoers.save file.
How do I check permissions on /media?

The output of lspci seems to have been omitted.

For the wireless problem, please open your wireless router to allow access
without any encryption and try to access it. Are you able to do so?
From your output, your wireless router is eth1. Since you're using Ubuntu/GNOME, you should have a "connection" icon in the upper, right area of your screen. When you right-click on that icon, you should see a list of access points visable to your wireless device. (Since it's a Broadcom device, you may need to run b43-fwcutter on the DOS .inf file to extract the firmware needed to get the device to work properly.)
Your problem may be as simple as an update to the b43 driver changing the location where the driver "looks" to find the firmware it needs.
Wait: I just looked at your lsmod output, and the only wireless network driver I see there is a r8169 driver, which is a driver for a RealTek 8101E. Are you sure you've got a Broadcom device? If so, you may be loading the wrong driver.
I tried deselecting the Broadcomm ATA driver and connect. I was unable to connect both with encryption and without.
I'm not sure which driver I need though. Is there an easy way to bring up my components to confirm? I looked for a menu option to see my hardware components but couldn't find one.

I meant to say lspci, not lsmod, in the previous post as the sample output shows.
Note post 4, above, where lspci output is reported as empty.
Note to OP (ajcollette7): When including console output in a post, surrounding the pasted output with CODE and /CODE tags (i.e., the words inside square brackets) preserves the spacing and make the pasted text much easier to read.

Yes. By default multiple white spaces are reduced to a single white space when you post to a thread. The code tags change the defaults. There is a complete description of all the BB tags you can use available if you click on the BB Code link in the small box at the bottom left of the page (after you scroll there, of course). (I copied that link into the prior sentence for your convenience.)

If you do a ls -l /bin/mount, is the s ("set uid") flag turned on? There are several command that require access to kernel areas to work properly, so they need to set their "effective" user id to "root," and the s flag indicates that this has been done. Here, for example, is the list of such command in a Jaunty system:
