Yeah, I figured that out some time ago and use BOTH at various times for
different reasons. I have 3, 4, and a 6 dB attenuator so I can compare/correlate
dBm at 10 dbm. Thanks for a useful tool, Andrew!

I typed in the Adapter model info and re-downloaded Vistumber...no problem now, got it. Also under Vistumbler Settings I found the dBm limits and, yes, it does work to at least -15dBm (where I set it and also set to -100Dbm= don't know it this will take me to the bottom of a graph on a weak sig/ ALL...

I just downloaded another wireless card on another computer and see "No Adapter Found" This is a new Mediatek RT2870 wireless LAN card and apparently it is not approved yet by Vistumbler? I posted under NO ADAPTER FOUND too. Clicked on UPDATE MANFUACTURERS under EXTRA but that didn't help. :roll: By...

No adapters found

Hi Everything works on 1 computer with the Alfa card system except the sensitivity. So, I download another Adapter that is relatively new on another computer. No Adapters found for this manufacturer. Here is the information on this adapter. Mediatek RT2870 Wireless LAN Card. MAC: address: 7C-DD-90-A...

Thanks! Another problem I have vs. what I see on YouTube for Andrew McNeil is that when I have a list of APs and see the weakest with signals down -100dBm, and click on any of them and use Graph 2, none EVER GO BELOW 35% ON THE GRAPH. Is there a method to correct the dynamic range of the display so ...

I have the Graph with several patterns done over a period of time as I measured and compared
different antennas. I only want to print the Graph. I have taken some photos but they are
not clearly focused.

I tried that and the 'hour glass' flashed a second but nothing happens. That's
a shame we can't print a graph but I certainly appreciate all your time and
help. Byron :D

Hello again,
Vistumbler is fine and I've established good graphs with important information...now I can't find a
method to print it so I can label the different items tested.

Sorry 'bout that. This forum is for Vistumbler. I have NetStumbler and compared
to Vistumbler's dBm figures, NetStumbler is down -15dBm (difference) on all
APs. So, my question was, which program has the most accurate dBm figures?

Hi Jon, Thanks for the email and info (just got back). We have similar backgrounds. Yeah, I meant Net Stumbler! As a member of the G-QRP Club Int'l, I wrote quite a few design articles (SSB Xcvr 17m, 10W Linear Amp, Ant. articles, Resistance bridge, etc) for their magazine. Also developed my own min...

McNeil's graphs/presentation is exactly what electronic engrs and antenna designers want to view and analyze. That's why he has such a following worldwide. Vistumbler is a very good program. It does have a competitor called Network Stumbler which appears to be off by -15 dBm on Receive Strength plus...

Thank you very much for your instructions, Phil. Perhaps a picture in the beginning would have been more helpful. Here is one of many Andrew McNeil's YouTube videos. Kindly look at the Vistumbler presentations from 7:45 to 8:56 minutes and you will understand what I desire to see. One second would b...

Ok, fine, thank you. Now, how can I shorten the time interval between points
so data points are very close together?

You do not understand the question. I only have one network card (Alfa). I physically disconnect and change antennas for comparisons between them. This is done hundreds of times by Andrew McNeil in his YouTube videos (with various antennas) using Vistumbler. I wish to duplicate his procedures with t...

I wish to have a graph monitor a signal in percent (%) so I can compare gains on different antennas> How does one do that? PS Currently I can see many APs and monitor their strengths in dBm. I also found a way to change antennas and see their continuous red strengths in dbm. This graph starts on the...
