Read signal/noise level on WAP-1966

Is it possible to connect to WAP-1966 and get some statistics like netstumbler gets from wireless lan cards?
Is powerhack possible with WAP-1966?

If you're talkin' about WAP-1966 from Planet then find out that's a fine AP, reliable and fast, but unfortunately you have no possibility to read the signal strength with it as itonly has the signal level in % of beacons returned correctly and that's bull-sh*t, itdoens't tells you anything about the real signal strength.
 However, you can connect to this AP (WAP1966) using a PCI or PCMCIA card with an advanced chipset (intersil prism 2.5 or newer for example) and read the signal level that WAP1966 outputs in AP mode.  I personally used a spectrometer and it outputs around 15.5-16 dbm, which is very good.

Thank you kronostm.
I was trying to connect to it using SNMP to read statistics, but I don't know why I can't connect to it using Atmel's Access point SNMP Manager (SNMP enabled on WAP-1966).

The problem is that I am using two WAP-1966 one with ANT OM8 omni and other with ANT YG13 yagi pointed to it, but I can't establish a connection on 500 meters distance with line of sight. Please tell me if you have any experiance using it outdoor.

we're only using them outdoor.
Well, two WAP1966 with line of sight at 500m and the antennas you specified should DEFINETLY make a strong link.
What can be the culprit here is the cable you used and it's length. As 2.4GHz signals have big losses on cables , I recommend you to use some low loss cables with 30-35db/100m loss and don't use more than 4 or 5 meters of cable, even thouh this means you'll need some outdoor boxes to place the APs into ... that's the way we do it. I'm a Planet reseller in Romania and personally set up lots of connections in 2.4GHz, all outdoor, in fact most of our providers use wireless connections instead of wiring a whole city.

 The Evil-ution of Network Security Threats

What are the hacks that forever changed the security industry? To answer that question, we created an exciting new eBook that takes you on a trip through hacking history. It explores the top hacks from the 80s to 2010s, why they mattered, and how the security industry responded.

I am using power over ethernet, so I don't think that loss is a problem (pigtail is 40 cm long). That's why I am trying to make some measurements to see if the problem is in cable connections or there is a lot of noise in the area.

as I already said, you can't measure with those APs, but you can use a spectrometer or a card with a decent chipset that netstumbler supports, however, it's bloody strange that it doesn't work ... even in heavy specter pollution it should connect. Maybe some broken connectors ?  I don't know ...

Thank you.
It is helpful to me to find someone who has the same equipmet and it works for him.
I'll doublecheck again the connections.

No problem.
Please let me know what was the problem. I'm always willing to know about possible culprits for broken wireless links.

I am suspecting that yagi is not mounted properly. It looks like it is created for mounting for vertical polarisation, and I mounted it with horizontal directors (I established a connection only once for a a short period of time and only with horizontal directors so I mounted it horizontally). I am not sure is it making a big difference.

Is it OK if we continue the converstaion in experts-exchange even if the answer is accepted ?

there are only a few omnidirectional antennas with horizontal polarizarion and I guess yours is not one of that as the horizontal polarization antennas are very expensive. What's the diameter of the omni antenna? If it's below 6cm then is a vertical polarisation antenna as I assumed and in this case you have to put the yagi accordingly.
Indeed, horizontal means a much higher gain, but they are expensive and have a bigger diameter.
