whats the chance that a wireless transmitter will transmit thorugh 3 brick walls? trying to create a wireless lan better 2 semi detached house's ( me and a neighbors )

There is every chance a wireless signal will go through 3 walls. I can take my laptop through 2 walls about 20 meters away without ANY degradation at all! :).

I have a friend who lives in the downstairs flat of a small terraced house converted into 2 flats. When he plugs his laptop in, he can sometimes see 5 wireless networks other than his own.

Meanwhile, I can't even get my wireless network to stretch from the first floor to the basement.

hrmm thing is i dont want to buy the equipment if it wont work

Well we never got our wireless network going from PC upstairs to one downstairs. They just wouldn't find each other no matter what! However, there are 2 others in our area and we can connect to one of them! Neither of these are on either side of our house either.

And the lesson is?.......

Make sure you lock your wireless out to your own PCs :thumbsup:

Must check ours after ME's latest strop :suspect:

It is indeed Strix :thumbsup:

buy branded parts, if you can get 802.11n (or pre n) kit, this will have extremely good range compared to g or b kit.

but that's why we have no probs :thumbsup:

What's the distance between the two points? You're never gonna know for sure without trying it as the compostiition of the walls and even the furniture in the rooms will have an effect on the signal. No chance you can borrow some equipment for a quick test before hand?

I have an Asus internal PCI wireless card with an external antenna. It's so good it even picks up a signal from my Wireless router when the antennas aren't even plugged in. I can even pick up a signal from my neighbors wireless network who live accross the road from me.

If you have problems you can build/modify antenna's for your needs also. My bet is you shouldn't have any problems whatsoever. I did once have a PSU that interfered with an adapters signal but I think that was a rare case.

Never heard of the n ones cyclone are they new? I have b but can still pick up the signal right at the bottom of my long garden so they must be good.

I've got this

http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=152539

card in one of my PCs and can pick up two neighbours networks from hundreds of feet away. The signal is much better with this indoors than it is with my laptop outdoors.

n is the next standard, still going through approval, but some manufacturers are shipping pre n kit which 'should' be compatible.

The range is supposed to be better by a factor of 10 or thereabouts. Speed is also higher and degrades gracefully with distance.

The ability to penetrate walls dependfs on the product and its hit and miss. Do as Cyclone syas and get an n series one. Belkin have just brought out a new one.
