Yes, ping by default never stops.  If you just want it to send a few packets 
you can use the -c option.

Did you try your applications once you had your connection up?  They should 
have worked as well.  I suspect the problem is with the configuration you 
have in /etc/network/interfaces.  Or maybe the problem was with your WEP 
configuration.  Try recreating the configuration you applied in steps 1 
through 3 in /etc/network/interfaces.  Something like:

iface mytest inet dhcp
  wireless-enc off
  wireless-essid myessid
  wireless-channel mychannel

Then bring ath1 up like this:
ifdown ath1
ifup ath1=mytest

Then test the connection.  Try pinging and some other applications.  Let me 
know how that works for you.
