Data transfer rate question

[rwo1]

I have recently installed a WLAN. The primary PC is connected via ethernet cable to the dlink 614+ wireless router and switch, the other PC is connected to the router via a dlink 520+ wireless pci adapter. I have an excelleent connection- the link strength and quality are100%. I have two questions: 1. How come if the network is supposed to be 11Mbps, the data rate only reads 56-80 kbps? Secondly, and much more important to me is, when I copy a file from PC to the other PC, the data transmit rate is reading between (as I have said) 56-80 kbps, however, it takes 15 minutes for a 4 MB file to move from one pc to the next. The data rate is truly as I have stated(I checked it with Qcheck utility). It seems to me if 50 kilobytes of data are moving every second then it should only take 80 seconds to move 4 Mb of data. When I download a file using my dial-up modem I get approx. 5 kbps transfer rate. It takes approx 25 minutes for me to download 4 Mb using my dial up modem. Any help or insight into this problem would greatly be appreciated. Thank you.

Are you mixing up Kbps and Kilobytes on whatever you are monitoring with ?

Kbps = Kilo bits per second

A dial-up 56 Kbps will yield max ~6.5 K bytes per second download rate from the internet.

You are sharing a 56Kbps dial-up ?

In my experience the LAN throughput (PC to PC) with 11Mbps 802.11b generally yields about 3.5-4 Mbps max -without WEP. Quite dissapointing really, but normal. (802.11b is half duplex). A full duplex wired LAN will give max ~80% of rated speed (e.g. 80 Mbps on a 100Mbps NIC).

If you download the Netstat monitor from AnalogX you can dynamically monitor both the on-going throughout and the average. You can set it to show bits per second or bytes per second.


I don't know if this helps you.
