Long range antenna taking over signal from laptops?

It's not the bandwidth because i've limited the machine that uses the long range antenna. And it seems to be the cell that's 'taken over' because even connecting to the router is difficult, not just remote servers on the internet. The long range antenna/computer uses the connectify software. I've been googling a bit but have come up stumps so thought i'd post here and ask if anyone has any insight into what may be happening.

Enabling RTS/CTS (on the laptops) might help.

use the 2.4g button to get the channel spread

InSSIDer only shows other access points that you can see, it doesn't show transmissions from client devices - which might be nearer to you than the access point they are talking to. And it won't be much help if the problem is caused by different devices within the same SSID.
Edit: I'm assuming the OP wants the machine with the long range antenna to be able to communicate alongside the other laptops.

If i connect through ethernet the problem goes away. The antenna is pointed at the router. Sometimes machines can see each other sometimes they can't, very intermittent.
Yeah i want the machine with the antenna to communicate alongside the laptops, but only to the internet really, not fussed about networking. The antenna machine is secondary importance, it's a mate that i'm allowing to use my connection because he doesn't have a phone line where he lives.
I'll keep looking. Thanks.

im sure Sean wont mind me posting but take a look at his implementation Here
Are we talking 50-100m, or we talking a few km?
You'll also probably find, that if your using a high gain / long range antenna, its "too powerful" for the router your using (if its too close), and is overwhelming the other devices (e.g. they cant get a signal because the 'air' is too busy (its dealing with a massive signal already)) if that makes sense.
A little more detail in what your trying to acheive would be helpful i feel
Regards

As for more info: The distance is probably ~30m. I think the antenna is quite powerful although i'm not really savvy on this stuff. From what i understand it's a 2200mW +18 DBi directional antenna. It uses a high power (although what that actually is i don't know), WiFi RF amplifier. Reportedly it will reach a few KM.

This is my point
Normally with these sorts of "high power" antenna, your better off getting 2 - and pointing them at each other (rather than at a router).
Quote , its "too powerful" for the router your using (if its too close), and is overwhelming the other devices
Sounds like i was right tbh chap, if you can reduce the output power of the antenna and see if it makes a difference? I have a little knowledge of this from playing with Cantennas and wifi crippling from college (we tried to disrupt wifi signals etc, and 'swamping' the signal is a good method)
You'll probably find that the kit you can find these days is probably quite alot faster than what Seans using though, (technology advances and all that jazz..)
Are we looking at something like This or more of an "outdoorsy" wifi AP sort, like Seans?

Quote likely to be causing problems for neighbours
If they're close enough, yes, definitely. but it depends entirely on the output of said device, id say that antenna is more for pointing at APs from a high vantage point, perhaps across a city... rather than doing a 30m short stint.
Sadly the BT adverts quite a good way of 'visualising' the signal (you know.. the coloured "wavey lines" around the room, just think how far the lines radiate out from that high power antenna in comparison to a 'regular' antenna.)
You'd probably better off puting a standard AP into a bridge mode, surely? (how dense is the area between the two points?)
If its *just* 30m, is it not plausible to whack in a Cat5 cable, and then put a switch on either end?
Regards

Have you thought of using the Homeplug system (providing your system is all on the same phase).
