Steve B, if your system is hanging after booting up then we would need
to capture the oops information. Could you please do so following
https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Capturing_OOPs
?

** Description changed:

  My home network uses WPA and this connects and reports no problems in
  this respect however I can only load web pages etc for the first few
  seconds after the connection is made. My train operator offers free wifi
  and this has no encryption yet when I connect to this - within a minute
  the whole system freezes - no mouse movement etc and only a forced power
  off will recover it.
  
- Is there an alternate driver or firmware package I need ?

+ + 3.0.0-16-generic-pae - card picked up but unsuccesful in connecting
+ and seemed to cause kernel stalls and system hang.
+ 
+ + 3.3.0-999-generic-pae card is not picked up at all.
+ 
+ WORKAROUND: blacklist r8192e_pci.
