@Nikky
Thanks for your reply and the welcome message

.
I don't use VOIP so I'll be ok if it's broken anyway heheh
a) easier said than done :P
b) say what? ...my isp offers this router to work with their vdsl2 line, they don't care about anything else. Only workaround to "remove" the TR069 is to chance either the firmware of this device or get a new router

. No need to ask anything from my isp, router can be set in bridge mode and put a vdsl router with a single lan port and connect it to speedport but why do that? point is to have this router working as expected but without TR069 enabled
P.S. I've went back(older firmware) but ISP keeps updating my router to this latest crap ...damn I hate this
