I have a two computer network. Here are the network adapter details of the two computers.

-Realtek RTL8111E Gigabit Ethernet Controller
-Broadcom NetXtreme Gigabit Ethernet

I'm using a CAT5e cable. But it gives only a 10 MB/s file sharing speed. What is the reason for this?

(In both the computers under "Local Area Connection Status" it shows 100 Mbps for the speed)

The Router or switch connecting the computers is probably only capable of 100MBit transfer speeds. Get a new router or switch that's capable of Gigabit transfers.

Now if you're using a crossover cable to connect the machines, that's a different story altogether...

Edit: While you're at it, you may also want to invest in some CAT6 LAN cables (at least 2... one to connect from the router or switch to each computer, but you may also want a third if you're anal about wiring up everything with CAT6 cabling for reliability). CAT6 cables are very cheap, like CAT5e cables. Shouldn't need to spend more than about $5 - $10 total for the cables. is a good source if you're in North America.
