<info>  [1519162864.8013] device (wlan0): supplicant interface state:
completed -> disconnected
added mentioned modules but I'm not sure which one can be still
missing because issue is still there:

Does somewhere exist some list of necessary modules? Looks like my
kernel is configured as one big binary instead of modules.
I have running modules:
lsmod
Module                  Size  Used by
ipt_MASQUERADE         16384  -2
xt_tcpudp              16384  -2
iptable_filter         16384  -2
iptable_nat            16384  -2
ip_tables              20480  -2
x_tables               20480  -2

Still looks like some iptables calls are failing. What about dnsmasq
error: dnsmasq: failed to create listening socket for 10.42.0.1:
Address already in use

Thanks  a lot.

BR,

marek
