19.7Mbits/sec for the WRT54G. See:
http://www.tomsnetworking.com/Reviews-39-ProdID-WRT54G-7.php

33.7Mbits/sec for the WRT54GS. See:

Try:
http://nitro.ucsc.edu
or other WEB100 NDT server. Look at the "More Details" and
"Statistics" buttons and see if they're complaining about MaxMTU,
RWIN, or other parameters. Also try:
http://www.dslreports.com/tweaks
and see if it also complains about MaxMTU, RWIN, etc. This is
probably NOT the problem since the directly connected computah works
as expected, but it's worth a try to see if something related is
screwed up.

Any chance that you might be:
1. Running 10mbits/sec on the PC or router ethernet port? 10baseT-HDX
will yield about 6Mbits/sec maximum. 10baseT-FDX will do up to about
9.5Mbits/sec.
2. Running 100baseTX-HDX (half duplex)? (NWAY failure) This will
result in erratice thruput. You can see the errors with:
Start -> run -> cmd <enter>
netstat -es | more
3. Have you tweaked the default receive window (RWIN) for the
increased speed?
4. Borrow a different computer and see if it does the same thing.
5. Crappy cables?
