Network Transfer Speeds

This is one I've been thinking about for a while and I can't quite come up with a final answer really, and maybe I just have to sit down and do some serious research, but i was hoping you guys would be able to help first.

I have a GB (1000mb/s) switch and a wireless G router (54mb/s) on a subnet under it. Traveling over a router is always slower than a switch, I know that, thats why i got the switch. I also know hard drive seek times determine speed of transfer rates as well as processor speed, motherboard, RAM, etc. If i wanna do better than the 11.5 mb/s over my switch like i get now, or the 2.5mb/s i get on my wireless, what should i do?

I looked at 10000 rpm HD's and i think that would help a bit, but whats the most important thing here, whats really limiting my speeds?

1000mb/s (Gb LAN) => 11mb/s?
54mb/s (802.11g) => 25mb/s?

Something doesn't add up?!? Maybe your measurements are wrong?

Mb = Mega bits; MB = Mega bytes ; M = Mega ; m = milli
mb, Mb, MB aargghh

K = 1000 or 1024?!?

(yeah yeah I know how it works, merely pointing out the confusion)

sirdice:
2.5mb/s

and actually i didnt check the difference between bytes and bits, makes a big difference now that i think about it.

Connection speed is 1000 and 54 Mb/s

data transfer rate seems to be in MB/s but i could be wrong

does that make sense?

is that where my problem was
