WiFi KB/s speed

maarten · 03-08-03, 08:06 AM

I've just "benchmarked my WiFi connection a little bit, config:

Linksys WRT54g
Pretec WiFi CF card (intersil drivers)

Transferring various files from and to build-in storage from my P4 system (100mbit to the WRT54g)

Big files:

Tx: 1300Kb/s
Rx: 80Kb/s

Small Files:

Tx: 600Kb/s
Rx: 40Kb/s

What is wrong overhere?

I'm going to check if the Pretec OEM drivers do any better, I have to do a hard reset anyway.

Maybe you are already planning on doing it, but it would be interesting to see if there is a difference between WEP and non-WEP transfer speed. Also, Power-Save vs. non-Power-Save

I wonder if these features, particularly the WEP, is behind the rather surprising (to me at least) difference in speed between the small files and the large files.

I already tried WEP.. deduct about 20-40% of the speed depending the filetypes/size.

Low transferrate, less hit (128-bit WEP is hard work for the Axim)

big files: big hit,
small files: low hit.

WEP slowing it down makes perfect sense, but what seems odd to me is that big files go at a faster rate than smaller files?

I copied a mix of jpeg, mp3 and programs.. the small files lowered the transferrate a lot, with big files the KB/s went up.

If there are 100 files with 10 kb it's of course slower than one file with 1000kb, as the device always has to create niew files, folders etc. instead of receiving one big stream!
Try to zip files into one file before transfer, that should equalize the speed!

Did a hardreset and tried the same files,

Tx was about the same but Rx was 150-250Kb/s small/big files...

The intersildrivers are not 100% compatible with the Pretec card
