_Frantic_ & dsnpevl can you send in your full system logs using info here http://kb.netgear.com/app/answers/detail/a_id/21543 with as much detail about your network as possible, router / switch models in use.

Info and logs are in the mail, as requested.

Would you both be ok to allow Netgear remote access to your systems at some pint if needed.

Don't drink beer myself :) I prefer wine.
OK with allowing remote access, but I'm not going to revert back to the faulty state, as I don't want any more down time on my website.

How's this for a shot in the dark? Correct me if my assumptions are wrong, because this UPnP is not my field of expertise.
- RN is using UPnP to connect to discovery server
- Router blocks UPnP
- connman 1.27-netgear1 package doesn't like this and ends up in an endless loop sending IP packages.

@_frantic_, do you have UPnP blocking on your router?

@OptimusPrime, were there changes made to UPnP handling between 1.26 and 1.27?

Not sure if this is related at all, but in regard to Wifi (direct):
[quote="Andrei Laperie @ tizen.org":2zlfzqwg]Please note that WiFi P2P is very sensitive to the wireless hardware/firmware. The combination that worked for us was Intel WP2/latest firmware/3.17 kernel. It is quite likely that other configurations might require extra work to enable P2P. [/quote:2zlfzqwg]
Could this be related to WLAN firmware / hardware in the router?
