"Secure" Icon on Open Network

Hello all,

My wireless is working well enough for me to post this, but does go down from time to time (still troubleshooting the cause… may be a Cisco Anyconnect VPN client, or Amarok).

From time to time the connection will just drop out, and I will have to reboot to get it to reconnect. In these times, dhcpcd eth1 ends up timing out, and if I look at the networkmanager log, that also shows a timeout. wllist scan will show the nearby APs, though, and iwlist will show the card as “connected” to an ap (ssid and all), but no pings will work and dhcpcd will continue to say it times out.

Anyhow, I noticed that most of the time when I do a scan in Knetworkmanager, the attached screen appears - http://filer.case.edu/jjm50/knetworkmanagerbroken.png

I am concerned, because I know that these are open APs, and also that it is showing quite a few too many. If I completely wipe Knetworkmanager and reinstall, are there any gotchas that might be worth knowing about?

Hi
Run a scan from the command line;


iwlist <your_interface> scan

Check the channels they are running on and yours and post the output.
You probably need to change your router channel and or aerial
positioning to reduce interference from the other AP’s.

I wonder if when you say ‘connected’ it actually means ‘associated’
which isn’t connected :wink:

Below is the output of the iwlist, note I’m sitting on a building at the center of a university with a lot of hotspots around with the same ESSID.

And below is the iwconfig for my card. Note that I’ve been connected fine for the past 2 hours, all is fine, just wondering why knetworkmanager thinks all those hotspots are “secure” based on its scan result.

Hi
Ahh so it’s a mesh then. I assume when you try to surf the web your
redirected to a web portal to authenticate, or is it just all open?

Its all open. Anyone can access the web directly (no redirects or user visible web portals).

I think its working better now… after testing around I believe it was the 64 bit version of the Cisco Anyconnect Client. Thanks for the help investigating! Looking forward to version 11.3
