ad hoc wireless speed-URGENT

#1 (**permalink**) 05-03-2008, 03:50 PM

It's 11mbps, i'm sending data(making an disk image) cross
one computer to other and the average speed is 650kb/second.
I have Intel wifi card bg 2200 on first computer and usb adaptor 108 mbps on
other computer ?
Thanks.

Wouldn't a cross-over cable be easier? And faster?

Ad-hoc is only specified to 11Mbit/sec connection speed. Some
wireless devices will go faster in ad-hoc mode, but it's NOT
officially supported.

Maximum thruput is roughly half the connection speed. See table at:
<http://wireless.wikia.com/wiki/Wi-Fi#Performance_and_Speed>

The Intel 2200BG will only do 54Mbits/sec, which will give you a
maximum throughput of about 25Mbits/sec.

100baseT-FDX over CAT5 will do about 80-90MBits/sec. Gigabit ethernet
will go even faster. Making disk images requires that the transfer
NOT be interrupted, which unfortunately is a common wireless problem
when interference stops the transfer. If you want speed and
reliability, I suggest you consider a wired solution, instead of
wireless.

I got only 20m long utp cross-over cable :)
Long cabels are annoying when working on real close and when you need to do
things fast. :) I'll manage...
