How would I setup my LinkSys WRT54GS v7 with dd-WRT installed on so that I can limit the download/upload speed of each client over the wireless network? (I don't want any guys to be able to download more than 50kBps).

You can use tc rate limiting, by running the following commands on your router (see here for details):
tc qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth 10mbit tc class add dev $DEV parent 1: classid 1:1 cbq rate 400kbit allot 1500 ....

I subscribed in a 1Mbps broadband internet (data only). The provider said that customers would only get 60% of it which is approximately 600kbps of the 1Mbps, which is enough for me. But I've been observing my download speed and it is limited to only ...

As an example, I have a 10mbps: If you understand the bit vs byte issue, then make sure the speed readings you're getting are correct.
The bandwidth jump initially beyond the limit before the ISP caps the speed.

It's a common misconception that you.
Are all significant factors in many applications.
L1/L2 cache size, memory bus speed, memory speed/latency, hard drive speed, etc.
That can (usually) affect things.

Hello,
I just bought an Ethernet hard drive. Everything works, but not as I expected.
When I copy a file with this hard drive, only 50% of the network bandwidth is used. As my computer only handles 100 Mbps network speed, the transfer speed is about 5...

Low end.
To the router, 5.5 MB is very respectable speed, close to the theoretical maximum (which is 6.75MB/s).

Astronomers measure something that is called "redshift" with symbol "z".
Z=1.4 means speed of light. All close galaxies have "z" lower than 1.4 it means they moving away from us at speeds lower than speed of light.
But all far galaxies have redshift far...

Galaxies are not moving said, the speed of light is the limit for object moving through space, not space itself.

For completeness, users running Windows can do.
For example:
trickle -d 20 firefox
That will set a download limit of 20 KB/s.
Running trickle to launch Firefox with a download limit (see man trickle ).
