Specs: Windows 2003 / XP/ 7, Core 2 Duo / 3 GB
I Have 2 laptops running on OS XP / Windows 7 and one desktop running windows 2003 connected to Netgear router. Recently i bought WD World Edition 1 TB network drive. When i try to copy the files (1.5 GB) from my laptop wirless, the speed is 2.5 MB per sec.When i copied same file through network, speed is 10 MB per sec.

My Router is 10/ 100 MBPS and all my system network cards are giga bit.

Here my question is why speed is so slow. If i am using 100 MBPS, then it should be some where that range but is copying files at 2 or 10 MB speed. How can i copy the files at max speed (100 MBPS)?

Are we looking at the same numbers? Are you using file transfer and network speeds in the same way?

If using network only based on taskmanager or performace monitor then try one client attached to the router and the one server only. Disable wireless and try it again. Be sure on the server you look at network options such at offload checksum and be sure to select speed.

It might be that the cable to the server is bad or poor. Some other issue with the quality caused by lamps or motors or RF or such.

urvijaykumar please review below:

1. Wireless has a lot of overhead. This means the data payload is smaller than wired.

2. The channel width is 100mbps. Problem is there is a lot of different processes talking on this bandwidth. Your file transfer isn't the sole operation of the network. It can never be because of the nature of CSMA/CD

3. You have to consider all the links in the chain between your laptop hard drive and that of the NAS unit hard drive. There are a number of systems that affect the throughput from one end to another.

Only do wired if you want the fastest transfer
Consider FTP to the NAS as a possible or better option
Use Winzip to compress the file then xfer over.
Get a gigabit nas and router.
