Unable to upload files/photos

Misunderstanding. I tried to say that connected to an Imac, it works perfectly. When i connect it to my netgear router(it is a dgn 2000 not a 2200) the mobile connection doesn’t work. I tried switching off and on remote connection on the dashboard and now says that i’m connected. I open my cloud app on my iphone, i can access to the hd but when i try to upload photos, the transfert fails after 32/96 kb
