Thanks Greg,

Yeh, when I look at the signal in Internet Connect (when the airport is not working) there is no signal most times and then occasionally it will light up and then sometimes a small signal then off again etc. I'm almost sure it is not the hardware because at times the base station will work perfectly and transfer rates are great.

Can you be a little more specific about what you mean when you say "it
doesn't work"? Open Internet Connect and check the signal level to ensure your machine is still talking to the Airport. Then in the bottom of the Airport window in Internet Connect you will get information about whether
you are connected to the Internet or not.  I know that I get flaky
performance sometimes on Airport (Snow base station) when I still have
signal in the menu bar display but Internet Connect shows me my Internet
connection keeps flapping.

Have a quick look at that and let us know the results. We may be able to
give more direction then.

Cheers

Greg

Thanks Onno,

I've put the laptop right next to the airport and it still doesn't work
at the time when it seems to be some kind of interference.

I'm wondering if there is a solution to this. When I first installed
the airport extreme base station it worked perfectly.  I could move
my laptop around the 54sqm office get the internet etc. Then about 6
weeks ago the airport just dropped out and it would go on sometimes
and off others.

I recently had a techo come out and check it and he said all was fine
and maybe there was someone in the area that is using a 2.4Ghz phone
and that was rendering the airport useless. I get a few hours use at
various times of the day but this is pretty much useless to me
because I need to transfer files all the time.

Does this mean the airport and the two airport cards that I bought
were a waste of money? Or is there something I can do about it?

Thanks in advance.

Well, yes and no.

My first test would be to see if the problem lies with the hardware
itself. The best way to do that is to have the two devices close
together (less than a meter) and see what gives.

It is possible, though unlikely that a 2.4Ghz phone would cause all
traffic to stop, because the whole point of the way they both work,
the phone and your wireless gear is that they shift channels around if
there is interference and both you and the phone would interfere with
each other.

The next test would be to change channels on all your wireless gear
and see if that makes any difference.

Finally, most wireless communications has no need to be running at
maximum speed, in my case for example, the satellite link can at most
provide 1Mbit, so my wireless gear doesn't have to run any faster than
that. Slower wireless connections travel further and are more
resistant to interference.

Of course there are going to be some differing opinions on the above
advise, but I suppose you have to start somewhere. I should also point
out that I'm not a radio technician, and the above is a result of
having fiddled for some years, not from any formal research or
otherwise.

(In other words, you're on your own and if you break it, you get to
keep both parts.)
