Signal strength doesn't change with the link speed, but your link
qualities look good, at least good enough for closer to 54mbps.

One thing with the link speed, I *think* clients and APs each set
their own link speed with their own algorithms.

Try changing to a different channel.  That's one thing that could
cause a good signal strength, but bad link quality.  The way you can
check to see if it's interference with another AP is by looking at "Rx
invalid nwid" in iwconfig.

Google wasn't useful, on this one.  Try grepping linux and your
wireless driver to try to find the problem.  Hopefully it's just a
coincidence.
