huh, I'm surprised.   I've had trouble routing 10Mbit through them at 
wire speeds.

The wrt54g(s) internally has a single 100baseT ethernet port attached to 
a 6 port VLAN switch.   WAN vs LAN are done with vlan switching, so 
effectively its a half duplex device.   The CPU is also brutally slow, a 
200MHz MIPSel system-on-a-chip with no cache, and very narrow memory bus 
with rather slow memory cycles.
