- Sep 10, 2004Some consumer "routers" have hubs or switches built in to them. Switches and routers are a rather complicated situtation.
Basically what most people call routers are devices that made decisions based on Layer 3 networking information and what most people
call switches are devices that make decisions based on Layer 2 networking. Most consumer routers come with 4 ports that may be
arranged as a switch or a hub (which is simply a layer 2 repeater that simple interconnects the ports). They typically do not let
you specifiy any settings. In reality there is NO reason that turning off autodetection would make any difference unless your card
is not autodetecting the correct setting. There are a few broken cards around that don't like autodetect mode and a few others that
will report to the kernel that they have negotiated 100baseTX when in reality they have not done so. You can usually tell based on
the lights on the switch/hub. Another thing to note is that the NSLU2 has issues with full duplex with many hubs and switches. It
works with my Linksys 16 port switch buy not my Linksys router's builtin 4port switch. I would think that if all of the parts were
in good working order you should be able to get 10MB/s. I am able to get 11.56MB/s. At some point there will be Gigabit USB2
adapters and we'll be able to get faster connectivity ... We can probably at that point get close to hard drive speeds.
