And you think calling anybody a dickhead will _help_ you get somebody to do
your school project for you?

1) Learn to quote (I can't see what you're asking, having missed the
original post)

2) Be polite.

3) When somebody else is _not_ polite, bet on it being because you asked a
stupid question, and see #2.  Yes, there are some dickheads on any
newsgroup, but drawing their attention to it won't help you.

Your English is better than most in this newsgroup.

A reflector or different antenna is the right answer.

However, there are a few tricks.  You can always trade speed for
range.  Normally, the 802.11g access points are setup for "automatic"
which means go as fast as possible.  This is a good thing under most
circumstances, but it doesn't do much for the range.  The access point
will constantly be trying faster and faster speeds, resulting in
constantly varying connection speed with weak signal.

The trick is to use a fixed speed at the access point or router.  I
suggest you start with 6Mbits/sec OFDM.  The client radio will
automagically adjust its speed accordingly.  Because it's a fixed
speed, it will not spend its time trying other speeds.

If 6MBits/sec doesn't work, try 2Mbits/sec.  The sensitivity is
slightly better at this slow speed.  Don't bother with 1Mbit/sec as
the sensitivity roughly the same as 2Mbits/sec.

Without changing the antenna or moving the unit closer to the source
there isn't alot you are going to be able to do.  The problem here is
the receiver sensetivity. This is something that you are not going to be
able to change. You could replace your card with a unit that has a
better receiver sensetivity, that is if you can even find one. The best
and cheapest fix would be change the antenna to a higher gain, but this
may not be possible depending on the card you have. Without being able
to be flexable there maybe NOTHING anyone can do that help you.

Re: wifi range


thank u for the info. i will try yoga classes. ok really thanks.
basically i am getting here that there is no boost to enhance the card
unlike freakin everything with XP and hardware running on XP. my
country thanks you.

It doesn't matter if this equipment was on windows, (this is not a linux
or windows issue) because the problem lies with the receivers ability to
pickup a poor (weak) signal. I do beleive Jeff made a suggestion that
may help without any modifications to the wifi card or antenna. That was
to limit the xmit rate to 2Mbps. It is truely amazing how one ask for
solutions and when they get them they get mad because they are not the
solution the one asking beleives he or she should get. The problem lies
with you wifi card and how weak of a signal that it can receive and
work. You options whether or not you should like them or not.

1. move the computer closer to the wireless transmitting source.
2. change antennas.
3. do nothing at all.
4. complain about the suggestions others have made.
5. try KungFu and kick that wifi card into submission.
6. Blame the problem because you don't have money to correct it.


Re: wifi range


If you have a WRT54G you can download non offical firmware DD-WRT gives
you a ton of feature and Hyper-WRT just adds a few, but they both let
you increase the power output of the radios in the router.

Increasing the output power does nothing for it receiving a poor signal.
Transmit power is not going to increase the receivers sensetivity.
Please don't confuse the two.
Oh by the way he doesn't have the WRT54G and these mods will NOT work on
the model Linksys that he has.

I presume it's a D-Link card, but he still refuses to give us any information
about the model so as to help us help him...
