Hello,
Thanks for using FixYa.
Well, if you really cannot understand the dBm conversions its really going to be a pain but here's the thing.. netstumbler already measures dBm so you don't really neet to calculate stuff. The higher the dBm the better. Please take note that dB is different from dBm.
I hope this helps. Thanks and have a good day.

Netstumbler is a bit flaky about which features work with which cards.
In particular, the graph only presents valid data for direct-connected (Not USB) wifi cards with Hermes chipsets. For Broadcomm chipsets, and for all USB adaptors, it presents a graph, but the numbers are meaningless.
It would be nice if they didn't enable the graph at all for USB cards, but apparently they dont' see it that way.
I can point you to the forum threads where the authors discuss this bug, but you specifically asked me not to. If you want the links, use the "add comment" feature to tell me and I'll send them your way.
And I'm sorry that you got an unhelpful answer the last time you posted. Hopefully this info resolves the confusion for you.
It's been a few years since I used wifi surveillance tools, but as I recall Kismet had a more polished feature set, and might provide the info you want.
Hello :
Try to uninstall the software and reboot the system and install it again and reboot once again . That can solve the problem .
good luck .
rate if useful please !

professional advice?!
Anyone's else insight on this, program works fine, prev 'tech' didn't even read my notes-
alfa usb adapter uses rtl8187, usb or not that driver is immed recognized in backtrack as well as used for testing w net stumbler for sensitivty
sn ratio, and power output,dbn correct me if I am wrong, I have kismet, backtrack 3 and 4, but do not see any similar features on kismet similar to netstumbler
61 dBm = 1258925.41179 milli watts
therefore divided by 1000= 1259 miliwatts
this obviously is wrong
the graph on netstumbler is dbm, correct?
this from online dbm to mw calculator:
1258 milli watt(s) = 30.9968064111 dBm
It is actually a 1000mw usb(1watt max power usb adapter)
What am I doing wrong in my calculating?
It seems the lower the dbm, the higher the milliwatts so maybe the graph is signal noise ratio? (noise)
I guess you're right, I just thought that netstumbler could be used somewhat like the realtek utility used with alfa usb adapters that shows signal strength, and link quality( right now approx 86% on both of these!) But you are right, the realtek utility is the best tool for optimizing your coonnection/ download speed. Thank you for your help.
