Seems like a configuration problem. I'm no expert.
I'd turn off encryption for testing. I'd try starting with a new location and configuring ethernet support again.
USB 2.0 dongle will work with USB 1.0 port.

You better give OWC 1-800-275-4676 a call to verify that these USB dongles will work with 10.3.
You would be better off with the more expensive dongle. The letters n/g/b correspond to the speed of the data transfer. You should match the speed to your existing router. You best match on the highest speed. N is the highest. G is middle. b is lowest.
