Quote from: Mr-TwoMy bro uses his Sony Vaio and my GF uses a Dell laptop. They bth have onboard Wrieless cards and have no problems.

Ive just checked The Netgear wireless utility on my work HP laptop and the transmit/recieve performance meter reads around 1% !!!

....Arrrrrgh  

Might pay you a visit Soopah to check this mini PCI theory of yours out!  

Real pain with this is that its not even my laptop!!!!!!

Sorry I didnt make it clear. It is dependent on your card.

Orinoco Gold = didnt cope well even with different channel, it picked up too much noise (poor SnR).

Netgear card = the replacement card, coped fine with it (SnR ratio is better)

Seriously, get hold of another card and do a scan around your house. You could be suffering interference from a neighbours network.

Quote from: M3ta7h3adim using channel 11 I think which is outside of the 2.47ghz unregulated band for general use and slightly into the military and emergency service band I believe. You can only use certain channels in certain countries. In fact some wireless equipment ask you to specify your country of operation and will disable the channels that are illegal in your country.

Yeah... if there is a emergency in the local area within the footprint of my wifi setup (which doesnt reach the front of my house). Then there would be a problem.

To be honest I havent checked what channel it is, but I believe I was breaking the law.

WIFI channels are set up so that 3 channels away from each other = the minimum interference. > 3 = interference from the higher up channels, < 3 = more interference from the lower channels. So if his scans come up true, either add 3 to it, or subtract 3 from it.

Also... DECT phones are bastards for screwing up wifi transmission. Make sure your phones are set on an appropriate channel if possible.

Its usually 5

Channels 1, 6, 11 are the only ones that dont have any overlap

Actually its 3.



Every 3 channels = a lull in interference from neighbouring channels.

Did you actually read it or just look at the pic???

QuoteFor better separation or due to regulation restriction, one may choose three (3) orthogonal channel sets, namely,

 

            Channel 1         2412 MHz

            Channel 6         2437 MHz

            Channel 11       2462 MHz

Im quite clued up on this sort of problem, many of my own customers have reported poor range with the netgear PCMCIA cards, regardless of channel, and my Acer laptop always gets a good signal at their sites.

I never disputed 1 6 11, I said that if you are 3 channels away from your interfering neighbours network, you will be experiencing the minimum interferance from him. I was disputing your "5" bollocks. Which was quite rightly well disputed, because it was as it turns out... bollocks.

Channels can overlap as much as 5. Thats why you try to use either 1, 6 ,11

or if you need more them 3 max to keep intereference to a minimum.

Hi guys

I get the same problem regardless of which channel I set my router to use. I also get the same problem at work, using 3 different cards (though all 511s!)

I recon that it could be an incompatibility issue between this card and the model of laptop.

Ill be getting in touch soon Nathan to try out your spare mini-PCI if thats still ok?!

Regards :-)

Sure is matey.

Hi people.

Worked it out, and it is a compatibility problem. Ive borrowed the USB NetGear Wireless adapter from work; from what we call the PC MOT kit :-)

It worked fine at work and is now working smooth and nice in the comfort of my Bedroom. Lovin it :-D

Cheers for all of the suggestions
We got there in the end...and you should all treat yourselves to a biscuit as a way of patting yourselves on the back!  :mrgreen:

L8rs guys...
