Prompt [Q] My phone keeps downloading something but I don't know where it's coming from

As mentioned in the title , whenever I connect to a wifi, my network speed statusbar mod shows that I'm downloading something at 150kbyte/s.

I've been trying to identify which app causes this, unsuccessfully. Wifi data usage reports "about 0.9gb used" however the app entries only sum up to 70mb.

Network log also shows the download rate but cannot identify which app is using it. I've also tried DroidWall to only allow Chrome to access the wifi but the ghost traffic still exists.

Reverting to nandroid backups of older versions of the rom still won't fix the error.

This does not happen however on a mobile data connection.

It's very irritating cause it makes pages load slow and I'm starting to think that it is a problem of the specific wifi (cant test othets now).

Anyone have any ideas on how to find thr the app causing this?

Im running latest Paranoid Android and googy max kernel
