Re: WLAN laufende Qualitaetsmessung
I read the original post now (in German, and as I am German, no problem). In his case I think "kismet" is a good start. So he can see, if there are other AP on the same frequency. I also suggest "wavemon", which shows all AP and its strenth. If the neighbour is sending weired pckages (maybe with aireplay-ng, who knows), then wireshark or tshark is working fine for it. Also you have then evidence for his doings, which is illegal (here in Germany). Maybe also the package "horst" is also helpful, which is designed for excactly these issues: check your traffic. (I have never used it for now). Hope this helps Best regards Hans

Hi, Reco wrote: > Using aireplay-ng for the purpose of lowering signal quality > for neighbor WiFi can be subject to criminal penalties That would be a good catch in a neighborhood feud which normally is rather faught by unnecessary lawn mowing, loud music, stinking garbage cans, or obscene garden gnomes. (The use of song loving roosters is widely banned.) I rather imagined a radio noise generator like https://commons.wikimedia.org/wiki/File:BWB_23342_ARTUS_Radaranlage_Typ_ME_0632.jpg Have a nice day :) Thomas

While tshark, wireshark or plain tcpdump can be used for this purpose, it would take a non-trivial post-processing to show signal quality/junk ratio grouped by APs. An invocation of 'airmon-ng wlan0' is much simpler IMO. Of course, if neighbor in question actually managed to connect to OP's APs, and wreaking havoc from inside the OP's LAN - then wireshark would be priceless. Reco

I believe tshark (and wireshark of course) is also be capable of showing bad or corrupted traffic. You can set filters, i.e. to filter out rejects and similar, and if they are abnormal high, you know, something is bad. Just an idea... Best Hans

Followup. Using aireplay-ng for the purpose of lowering signal quality for neighbor WiFi can be subject to criminal penalties and therefore is not recommended. Reco

Just observe which WiFi channels are most crowded and switch own Access Point (s) to a least crowded one. Repeat as needed. Reco

Hi, debian-user ist englischsprachig. Probier's mal auf dem deutschen Ableger: debian-user-ger...@lists.debian.org Just in case somebody knows a program for WLAN quality surveillance: The OP suspects that his neighbor after annoying the dogs has now taken measures to hamper the WLAN. The question is whether there are programs which can diagnose WLAN quality problems and identify potential causes. Have a nice day :) Thomas
