"My internet speed is 140Kb/s."
I think you mean 140KB/s.
B=Byte b=bit 1B=8b 140KB/s=1132Kb/s.
To find out your actual internet speed run:

Almost all basic routers, cable/DSL modems, and computer Ethernet cards are capable of 100Mb/s speeds between itself and the computer. They are usually rated 10/100 Mb/s.
To find out your network speed:
start > contol panel > open network connections > Right click on network and choose status > General tab lists speed (Mine was 100.0Mb/s)
My computer will communicate to my DSL modem at 100 Mb/s, while my Internet speed is still restricted to what my ISP provides me. In my case my measured DSL speed was:
2.2 Mbps download speed and 430 Kbps upload speed.
Buying a gigabit switch/router will increasing the speed between the router/switch and your computer to 1Gb/s but your internet speed will remain the same.
A switch is faster than a router at communicating between computers connected to the switch. This has to do with the differences in how a router and switch communicate with the computers on the network (see tutorials below). A gigabit switch will be able to communicate between computers 10 times faster than a 100 Mb/s switch. If you transfer a lot of files between computers or backup to another computer you will definitely see a difference. There will be no difference in the internet speed as the maximum internet speed is much much slower.
Switches and routers may also contain the modem and a network printer port.
Per Netgear you can use UTP category 5 cables for a gigabit switch.

I would probably use category 6 cables.

Network Cable Ratings
http://www.connectworld.net/syscon/support.htm
CAT-5 is rated to 100M (meters)
CAT-5e is rated to 350M
CAT-6 and CAT6e is rated to 550M or 1000M depending on your source
CAT-7 is supposedly rated to 700M or presumably 1000M
