Is This A Network Problem ?

Are you sure about that? I've had trouble with manufacturers connection tools because they are loaded after a user logs in causing a chicken and egg situation.

I think that the real question is 'how does the teacher know that the card is sending but not receiving'? Has this teacher got a wireless sniffer that can see the packets going past?

I would bet it is more likely that it isn't associated with the AP, is associated with a rogue AP or the AP has 'issues'.

double click on the little network icon in the task tray (if the icon is turned on)

Nothing magical with sniffers required

That isn't particularly accurate because that shows all the packets that windows has sent even ones that haven't reached their destinations. The counter that has recorded all the "sent" packets will be showing all the 'control packets' that have been sent to the AP.
Ethereal would be the best way to check what EXACTLY is being sent from the wireless NIC.

@DMcCoy: As penguinpowered has described, the card might think that it is sending packets but nothing is happening.

Another thing worth checking is if the card is switched on (I've now managed to teach my dad not to turn off the wireless NIC!).

I'm just pointing out how you can see that its only sending, if you do not have authentication set up correctly as I mentioned then windows will show 0 recieved in these stats. Windows will quite happily tell you that you are connected to a wlan even with the wrong auth settings, it just sees the ssid and pretends that its connected to a network.

Very painful experience. Sony Vaios are buggers for this.
