ThinkPenguin WiFi adapter disruption

Better to view this as a security feature rather than a sign of failure. My own ThinkPenguin dongle experiences broken connections now & then, more so when I've got multiple nMap scans going on. No data is ever lost; and the scans pick up right where they left off when the connection is re-made. Unplugging & then reconnecting the dongle re-makes the connection OK ... if it doesn't, use a different USB port to wake it up.

I also have a Think Penguin extended-coverage device, which has the accessory antenna for boosting coverage. If I'm using them while I'm running the nMap scans, the connection breaks more frequently, confirming the cause: too many competing WiFi installations. Disconnecting the antenna helps a lot; the coverage drops dramatically, but connects to my own router reliably.

That said, my connection indicator never lies to me: if the fan is blank, there's no connection; if there are multiple "waves" it's connected.

I'm using Trisquel flidas on a ThinkPad T420 and the "Indicator Applet Complete 1.12.1" See http://www.mate-desktop.org

Thanks for your reply! For my understanding, what are nMaps? Why do you consider this nuisance as a security feature?

Also with me, not data is lost but sometimes it's really inconvenient when the wifi breaks in the middle of an online booking or the like.

For the record: I'm using Trisquel Flidas on a ThinkPad L540 and the "Indicator Applet Complete 1.12.1", too. My connection indicator, however, is of dishonest character and has always shown the questionable habit of lying a lot, and in my face! (Eg, when the connection breaks down, the indicator applet still shows a good connection. That's also why I suspect it might be a software issue.)

Hoping for further help here!

To find out more about nmap, type "man nmap" in a terminal; to find out even more, type "info nmap".
To improve your understanding of syntax, etc., explore others' experience with online nmap searches.

This webpage illustrates my use of nmap to find out which attackers to my website were operating
from servers with open ports 3389, the Windows Remote Access Port, commonly also left open by naive
users of the so-called Cloud, which is a marketing scheme to put unused server hard-drive capacity
to work generating income for Internet Service Providers:

About your Indicator Applet: It could be that your connection to the router is OK, but that the
router is getting overwhelmed by external traffic.

I would also be suspicious of the USB port into which your ThinkPenguin WiFi dongle is plugged.
Try a different USB port. I had a scan script running for almost two weeks, during which the
WiFi connection was broken several times; the script kept right on from the point of interruption
when the connection was re-made. I've sometimes had to try another USB port when the connection
didn't wake up right away on reconnecting.

ThinkPenguin does provide a firmware update for their WiFi dongle; don't hesitate to ask. My (free)
update came with clear instructions, which made its application easy and quick.
