i have neo cam NIP 03 clone (i think so, mine has h.264 decoder also).
my network is like this camera :-
3G USB > TL MR-3020 wifi router > IP cam (wifi)
and for PC :-
3G USB > TL MR-3020 wifi router > PC (LAN cable)
without 3G connection (i.e. internet) , i can access my cam on PC (i.e. on LAN)
but when i connect USB router (TP LINK _ MR3020) to my router and
connect router to internet , camera instantly drops connectivity with
wifi router. so it can not be accessed via local PC or via remotely.
don’t know the problem, but due to this problem, i can not access it remotely
i have done port forwarding OK AFAIK (its 8888)
