Hi

I'd like to get some decent range from my wireless network running a d-link dsl-G604T. I was thinking of getting an antenna since everyone in the house was complaining about signal loss even though i placed the AP in the 'center' of the house.

Are there specific antennas I need to look out for to suite the kind of range / area of my house?

Seriously?
200m x 200m?? Your house covers 40 000m square?..... thats like huge!
No wonder you're getting signal loss!

For most people's (small) houses or small offices, this kind of thing should be ok:

or even:

But you may need something bigger, possibly contact Poynting or Miro and ask for their advice.

PS: Best idea is to pace out the longest distance that the signal needs to travel and note how many walls, floors, tin roofs, etc that the signal needs to penetrate.

The biggest problem is the distance the signal needs to travel through walls.

If the signal travels perpendicular to the wall, the path length is quite short. But the moment it is not perpendicular, the path length increases quite dramatic.

I once had a similar problem. The antenna was in the corridor. That meant that the signal path was going through quite a bit of brick. Moving the antenna to the edge of the offices solved the problem. Although the total path length was much longer in many instances, the brick & mortar path length was much less.

Try it with a pencil and paper! It is amazing.

I have for sale a dish antenna including cables, a cantenna (imported ) including pigtails for mywireless. You won't need the pigtails tho, but the rest are all designed for wifi.

Offers welcome. If I get sh?t offers, I might become part of JAWUG

I agree with kaspaas an arf9999 a 2.4 GHz antenna will do the job. More or less have a look at the 8dBi omni-directional antennas that you can just attach to the DSL.

Getting another DI-624+ will only complicate things as the DSL can only run in AP mode and the DI can only run in AP mode, there'll be no way thay will communicate.

Have a look at the DWL-G520 H/W: Bx PCI adapters from D-Link (www.dlink.co.za) and 2 external antennas's product code is ANT2400-1400 for a range of 700m clear line of site.
Also please remember when linking up 2 PCI adapter at this range not the let the jumper cable (connecting the external antenna and the PCI) be longer then 30cm.

I'm not quite sure what you mean by monitoring mode.
Monitoring the signal strength and quality?
