Need to make sure the system sees it as a usable network device.  Do: 

iwconfig  ## verifies if the system sees it as a proper 802.11 device, and/or ap association

ip link  ## sees the nic as a real interface

ip addr  ## shows ip layer data, if it has an address

cat /var/log/syslog | grep NetworkManager  ## verfies if network-manager is trying to do anything with it

Also, does the systray applet show the network scanning for any wifi devices?  You should see *some* ssid's being found.

lspci sees SOMETHING at least. It says 

03:00.0 Network controller: Ralink corp. RT5362 PCI 802.11n Wireless Network Adapter

so it is detected.

The card in the other computer is almost identical It is pci-e wile the one not being detected is a pci card.

Look at the pci devices with lspci, grep for network devices:

You should see a like device there, your new card.  If it's not being detected properly, search dmesg output looking for an unknown device, might be a firmware thing or something.  Dmesg should at least tell you what pci-id, vendor, or model of chip to then google why that doesn't load under your os.

I got two wireless cards (netis wf2118) for two computers. both computers have mint. One card is pci the other pci-e. the pci-e card works great. the pci not so much. the green connectivity light on the pci card is happily a solid green. Any ideas on how to get it to work?....

I just googled it and the one hit I got said he had a dead card. How can I tell if it is dead?
