[CALUG] 10.04 broke my wireless and ssh

[Ed Browne]

Hi,
    I did the upgrade to Ubuntu 10.04 as soon as it came
out, and a couple of problems spontaneously appear which
I can't seem to resolve.
    My wireless stopped working, I no longer even see the
icon on the panel which showed wireless networks/strengths
(what was that app?  Perhaps it's not in the default upgrade?)
It's obviously disabled, as you see here:

root at brazil:/var/log# lshw -C network
  *-network              
       description: Ethernet interface
        (this is eth0)
...
       resources: irq:16 ioport:2000(size=256) memory:b0200000-b02000ff
  *-network DISABLED
       description: Wireless interface
       physical id: 2
       logical name: wlan0
       serial: 00:19:db:9a:f8:b4
       capabilities: ethernet physical wireless
       configuration: broadcast=yes multicast=yes wireless=IEEE 802.11bg
root at brazil:/var/log# 


But I can't see how to enable it, I've been installing
everything wireless I can find in synaptic, but I don't
think I ought to need to do that.  Any suggestions?

Also, I cannot ssh into the box.  The box can SSH
to itself, which tells me the ssh server is running, and
the firewall is turned off, as per this:

root at brazil:/proc# ufw status
Status: inactive
root at brazil:/proc# 

but yet when I try to SSH in from another box on
the same router, it times out.  On the Ubuntu 10.04
box, I see only this error repeatedly in SYSLOG:

...

The IP addresses and name resolution seems to be fine
(mac is where I'm trying to SSH in from, brazil is the Ubuntu
10.04 host):

brazil:~> traceroute mac
traceroute to mac (192.168.1.69), 30 hops max, 60 byte packets
 1  mac (192.168.1.69)  2.582 ms  2.537 ms  2.579 ms
brazil:~> traceroute brazil
traceroute to brazil (192.168.1.68), 30 hops max, 60 byte packets
 1  brazil (192.168.1.68)  0.087 ms  0.037 ms  0.034 ms
brazil:~> 

but when I try to SSH in (or http in, or any other 
protocol I've tried) from "mac" it just times out.
One thing that puzzles me is that I cannot traceroute
from 'mac' to 'brazil' (even though I *can* ping 'mac'
to 'brazil'.)  I have no explanation for that either.

Any and all  suggestions gratefully accepted.

Thanks very much - Ed
