Mint and wireless networking

[Pete Holsberg]

Just for fun (this is a hobby, after all!), I decided to install Linux 
Mint 3.0 Cassandra to see how it handled my wireless card.

At first it didn't recognize it but I found the Admin tool for 
installing Windows drivers, and then lspci showed the card as a Marvell 
88e8335 which I knew to be correct from my Kubuntu installation.

I went to Network Tools and found two wireless devices, wlan0 and 
wlan0:avahi. Attempting to configure the first, I noted that it saw my 
wireless network and my neighbor's. I set in the WEP password, set it 
for DHCP and went to try a ping to my router.

No joy!! What have I forgotten about?

Additional information. Network Tools has a status panel for each 
device. Under wlan0, all the vales were "not available". Under 
wlan0:avahi, everything had a value -- even the hardware address! 
However, the values were not related to my network (eg., wrong IP 
address) and when I clicked on Configure, it said "Interface does not 
exist".

I'm puzzled.

Thanks for your guidance.
