Unknown traffic on wlan

---Moved to its own thread---

I have a broadcom device too, but I guess it's not device-related. The symptom: After connecting to the network via wlan, there is permanent (down-)traffic (which takes a huge part of the bandwith - even if everything is closed!). After some research I found iptraf, which shows a stream something like

UDP (1356 bytes) from 10.1.133.6:46822 to 239.1.1.122:2000 on wlan0

I don't get this line. Local ip is (192.168.x.x). So far I figured that it might have something to do with iptv (which I do have, but NOT on the computer, it's a different device, but I cannot explain how it interferes). Research suggests that 239.1.1.122 is a multicast address. The internet via wlan is slow (obviously the stream taking the bigger part of the bandwidth - free space is not getting less on / or in the user directory).

Re: Unknown traffic on wlan

Ok, thank you for showing the direction.

I was just not getting at all what is happening but with the keywords I'm starting to understand what is going on (at least I hope so). It was surprising as the traffic is not even shown in tools like Net Activity Viewer but there is clearly a network misconfiguration. I will dig into it and I have a direction now.
