Cam says successfully connected but showing offline

G series bought in HK and the salesman told me I can use in Australia. Just tried to connect and it says successfully connected but it shows offline on the phone. I bought 3 of them. Please help. Thanks

Dear Sir/Madam,
it mostly caused by network problem, please check the network connection situation of your wireless router.
then reset camera, and add it to phone APP again.

Hi. A very interesting question. And for me it has its relevance, or rather I have a counter question. I previously bought a G series camera to use in my business. But recently I decided to move it to another country, with Load restacking logistics we already organized half of the transportation and now the production is stored at their warehouse, soon it will be delivered to the new location. So, do I understand correctly from your question, that such a camera will not work in another country? Now I will have to buy a new camera? Thank you for your reply.
