Problems w/ wireless connection after installing updates

[Matt Burkhardt]

Don't know how good / bad you are so if this is too detailed - let me
know....

Go to Applications | Accessories | Terminal

Type

iwconfig

and copy and paste the output into your return email.  You copy in
Terminal using Shift-Ctrl-C or by using the top menu Edit | Copy.  Look
for something that looks like

eth1      IEEE 802.11b  ESSID:"matthewboh"  Nickname:"ipw2100"
          Mode:Managed  Frequency:2.437 GHz  Access Point:
00:0C:41:D0:46:A0   
          Bit Rate=11 Mb/s   Tx-Power:16 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=99/100  Signal level=-54 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:2   Missed beacon:2

Remember that eth0 / eth1 / wlan0 or whatever that first line says on
the left.  Then type in 

sudo lshw -C network

and post the results - finally a scan that will look for wireless
routers.  I have put eth1 in the command but use the one you got when
you ran that first iwconfig command - send it back and I'll take a look

sudo iwlist eth1 scan

I went ahead and selected update (about 300 some updates were pending - I bought the laptop last Christmas!).  After the updates, the wireless network stopped working.  I connected by wire and that work, the dialogue for network.manager is different from the one her twin sister has (which I did not update).  Am I dealing w/ a bug?  The menu I get when I try and bring up network.manager does not look like the one on the other laptop.  The sequnce to get to network manager also seems different: System, adminitsration, network manager (rather than just network).
