Power on the Senao 2511

Psychoboy · 03-19-2005

The power on the Senao 2511 ext2 card is suppose to be 200mW. But it's also a variable between 10-200. Now here is the issue. When using NS it does not seem to be using the full power. Just recently got this card for the laptop and still messing with it. I can't seem to find anything that will help me adjust the power and force it to use the 200mW. Linux or Windows XP would prefer tools for both actually if anyone knows any or how to do it.

NS wouldn't really need to use it at Full power since NS is only listening for AP's, and not trying to connect. NS's ability to detect distant AP's is solely dependant upon the sensitivity of the receiver. The 200mw is only applicable for the output of the card, not the input.

And how were you able to come to this conclusion? And how does this fit in this forum? Hardware - Yes, Netstumbler - No.

Ok thank you for the information. Looks like I got some more research to do.

I thought NS was an ACTIVE scanner.
Xmit - "Hey is anybody home" type packet.
Rec - "Yep, I'm here" type answer.

Allegori time : If you shout but are deaf, you might not hear the responses.

NS is an active scanner.. But if NS can't hear the reply, it won't detect the AP... Logical

So it's correct to say that NS's ability to detect an AP is dependant on the cards receive sensitivity.
But of course the higher transmitpower increases the number of AP's that will send a response.

Stupid question, but does the Wireless Zero also send probe requests?

BTW, thank you guys for your advice and help. I won first place in computer science at the Houston Science and engineering fair, and am going to the state science fair in San Antonio.

Now would be a good time for you to get and read the 802.11 specification!

Congrats on the science fair.

Yep, I know. I believe I've said as much in another thread. I was just trying to jog the brain cells of the person asking the question.
