I have set up my wireless network at home and it works brilliantly.

But I now need to move the network to a small office. The network is only 1 desktop, 2 x wireless dell laptops, and 1 TM 2300 router. The office is the size of large Irish bedroom i.e.  v.small.

At the office the network does not connect (or at least very very seldomly does it connect). I must have some heavy interferance ?

In the intel/pro driver utility when I scan for availalbe networks I get one from the office nextdoor and not mine. (The same happens when I look for available wireless conections through the windows utility.)

Things I've tried so far -

I have changed the router channel. (and the laptops to match)

I have set the router to comunicate on my cards signal only ......11b.

I have boosted the laptops cards strength to maximum.

I have switched off the cordless office phone (seemed to make no difference).

I seem to get better connections when laptop is powered by the wall (rather than batteries)

I have set the laptops to connect only to networks for which I have a profile. - this is V. important.

So Can anyone give any extra advice on how to boost the router signal ? please.

Thanks

John
