This might be an antenna diversity issue, but I do not think this is 
likely if you haven't toggled anything in the driver.

Ping some host on your network, if you're experiencing about 50% packet 
loss, you're system is using transmit diversity alternating between each 

If this is not the case, you're not using diversity at all or just 
receiver diversity.

If the connection is miserable in general (snr or signal strength) you
might have swapped the aux and the main antenna.

The wlan driver usually offers a toggle to switch diversity on and off, 
usually through some sysctl or /sys interface.

The way you're describing your issue though, it sounds as if the driver is 
just crap...
