Problem solved - sort of...
I replaced the card last night. Both cards were Edimax 7128g cards but
the first one was an older version based on the 2560F chip which uses
the rt2500pci driver whereas the newer card, misleadingly also an Edimax
7128g is based on the 2561 chip and uses the rt61pci driver.
The newer card with the rt61 driver works perfect. I am getting the full
54M and my link quality reading is about 90%.
So my conclusion is either its probably a driver issue with the
rt2500pci driver and rt2560F chipset.
The good news is Edimax don't make the EW7128g with the 2560F chipset
anymore!
