Re: is 40mbit/sec on 100mbit home router 'reasonable'?

Are we talking LAN-to-LAN, or LAN-to-WAN here? I've used a WL500gp in the
not-so-distant past, and exceeded 40 mbit/s LAN-to-LAN quite frenquently.

WAN-to-LAN I never really tested; my DSL never exceeded 20 mbit/s at the time.

Huh? I lost you - AFAIK it does have a switch. What it is faking is having
separate WAN- and LAN- interfaces (the WAN port is actually just another port
of the switch, which uses vlan tagging to separate them. However, this means
that WAN-to-LAN traffic needs to pass this switch *twice*). 

In fact, I seem to recall that it is this very switch which made an attempt
to port NetBSD to these devices fail - the default configuration of the
switch is "Isolate all ports"; configuration is done using a binary
kernel module with no documetation whatsoever available, so even though the
rest of the SoC is mostly supported it ends up being pretty useless anyway..
