Reading the posts about wireless networks i like to share this info with you all.
A really good way to check wireless networks is to use the freeware program networkstumbler. It works with a lot of wireless network cards in laptops.
This program show's every API in you neighbourhood, show's the channels, and the strength of the signal. It show's ip adresses and the protection of a wap. I used it several times to measure the strength of a signal or to get info about other sources who have influence on the connection with for example a MVP-8400.
You can download this useful piece of software at : http://www.netstumbler.com/downloads/
Give it a try it's for free and works great.
Before you install make sure you read what wifi cards are supported other wise it doesn't work.
Good luck.

Another great tool is look@lan. http://www.lookatlan.com/
-shareware-
specify scan ranges, proof scan , trapping->email, graphical ping and more
Dave,
I used this tool for network diagnostic too. It is useful. What is the additional feature and function for paid version?
Here is a great free IP scanner that you can use to check for IP conflicts and open ports.

i have a Pocket PC with a wifi card in it. the driver that comes with the wifi card (pegasus chipset) provides detailed info of wireless/lans in the area, very similiar to netstumbler.
this has been a handy tool for reviewing wifi zones.
and now i've got my PSP, i can justify taking it to work because it has a great wifi search system as well, with a web browser built in
(just a bit tricky typing urls, but bookmark a few (eg, regular controller ip) and it's real easy)

with bluetooth, 2.4G video, AMX RF receivers and then wifi it's all getting a bit cluttered around some of my sites.
Jeff,
For Wi-Fi one is "AirMagnet Spectrum Analyzer" or Cognio ISMS Mobile (http://wifi.weblogsinc.com/entry/1234000727044139/)
Others are here http://products.wi-fiplanet.com/wifi/analyzer/recent1.html .
If you are looking for broad-range equipment, check for Tektronix, Aeroflex, Anritsu spectrum analyzers (some of the items for mil/gov use however).
If you have a spare oscilloscope and a directional antenna (including home-brew "cantennas") - nice intro is here "Poor Man's Spectrum Analyzer".
I'll check out the poor man's version article as well and see how much a used scope runs.

I was getting ready to order an older looking wireless analyzer from ebay when I stumbled upon this little gadget on the net. For the extra $20, I decided to try this one out. I just like the fact that there is some illusion of support
I'll do a complete review of the device as soon as I receive it and have a chance to test it out. I don't expect this device to be as elaborate as the packages selling for 3-5k, but I don't feel that the company I work for would be able to benefit any more from the full blown testers as compared to this device if it performs as advertised.

I just took a look at the specs on the tool, but I would only consider it if I didn't have a laptop. I believe you could easily accomplish everything this tool provides with a laptop, a wireless ethernet adapter and netstumbler.. or any other software package you prefer. But this is strictly my first opinion as I haven't tried this tool out personally.
Jeff
That's true. Netstumbler is pretty powerful. The main advantages that I see to the Test-um piece is that it's a little easier to wield than a laptop especially if you're waving it around, plus it boots up quickly (I assume), and is easy on power consumption and weight. Plus you can give it to a secondary tech to troubleshoot or verify conditions without the expense of an additional company laptop. Then there's the wow factor to the client when the installation crew starts pulling out all sorts of specialized test equipment that the customer hasn't seen before. That always adds to the professionalism and appearance of the company. With that said though, I haven't rushed out to order one yet

Now, the important stuff.... Just tried out my little WiSPY device here at the office and it seems to work well. I definately noticed a big jump in activity when I used the Panasonic wireless phone. I can also clearly see the activity generated by our wireless network. I tried using the microwave and it is also showing up in a similar fashion to that described on the website. I was also surprised to find an update to the software available online that adds a spectrogram view option. Overall, for what I need, I think this device is worth the $99.00 price tag.
Ohh and it also helped me pickup a lot of interference in my house from a neighbor. I switched to a different wireless channel and things are working better.
Jeff
Could you post the Make/model and other info in the tips and tricks section. I maybe interested in this unit.
As far as I know, this has always been in Tips/Tricks section. For info on this unit, go to: http://www.metageek.net/ .
You can download the software for free and view some of the sample scans they have on the site to see what the unit looks like in operation. I ordered a unit during the New Year weekend and it arrived last Thursday (They weren't shipping until Last Tuesday) so they ship out very quickly.
I hope this info helps, feel free to ask if you have any other questions.
Jeff
Just some suggestions
Jeff
we wanted to order one, but they don't accept orders outside of USA (at least from their website). trying to find a way to get one to australia now
thanks heaps for the info.
I took a quick glance and thought it was in the general section. Like I said this has already been a long year. Can we skip 2006 and move directly to 2007?
