speeding up data transfer?

yo,

how can i speed up data transfer from one computer to another? i am using
'b' type network. i want to send 1gb woth of data, but it takes 40 mins. how
can i speed this up?

thanx

use a wire connection

You start by disclosing the equipment you're using, operating systems
and the version. I am clarivoyant and can read minds, but it's a
holiday and I don't wanna exert the effort that remote viewing
requires. It would also be helpful to know if you're going directly
from one computah to the other as in an ad-hoc network, or whether
you're going through an access point. If there are any WDS repeaters
involved would also be nice.

Then we do some math.
1GByte in 40 minutes is:
1.024E9 bytes * 8 bits/byte / 40 min / 60 min/sec = 3.3 Mbits/sec.
That's about what you'll get with an 802.11b system, two wireless
coputahs, going through an access point, with an 11Mbit/sec connection
speed.

The only ways you're gonna go much faster is to either:
1. Sell your 802.11b hardware and go to 802.11g
2. Bypass the access point and setup the two computahs to talk
directly in ad-hoc mode.
3. Buy a DVD burner and use DVD+RW disks to move large amounts of
data (that's what I do).
4. Give up and go direct with an ethernet CAT5 cable.

Note that 1 and 2 are somewhat exclusive. 802.11g does not officially
support speeds higher than 802.11b speeds in ad-hoc mode. Most cards
will do that but there's no guarantee. If they do, you'll get about a
30Mbit/sec connection and about 15Mbits/sec tranfer rate in ad-hoc.
Cut that in half if you're going to go through an access point.
That's 8 mins per gigabloat for ad-hoc and 4 mins per gigabloat for
infrastructure (going through an access point) with 802.11g.

With a direct CAT5 connection, and assuming 100baseTX-FDX, you can get
fairly close to "wire speed". I ususally get about 80Mbits/sec which
which is 24 times as fast or about 1.7 mins per gigabloat. However,
at that speed, you'll need fairly modern hardware that isn't busy
doing things behind your back (spyware, disk indexers, anti-virus,
instant messenger, etc) that suck CPU cycles.

thanx for the help,
wats an ad-hoc and how can that help me? and how do i set one up.

i am using a belkin wireless router, and i have created a wireless wan
between my computer and laptop. i'm using win xp.

thanc

You might wanna fix the shift key on your keyboard.

Ad-hoc is also knowns as "peer to peer" between two wireless cards.
No access point required. You go directly from one computah to the
other. Speed should double. Since you didn't bother to supply a make
and model, I can't point you to the appropriate web pile for
instructions. See:
http://www.microsoft.com/windowsxp/u...02april08.mspx
Please ignore the part about using ICS to share an internet
connection. When you're done with the ad-hoc file transfer, switch
back to infrastructure mode to connect to your access point and the
internet.
