Have you tried downgrading the FW? I believe one other did and it resolved there issue.
If I read this forum earlier, I will not buy the 2 D-link cams. Actually, a colleague of mine bought a D-link router a decade ago. But it hangs from the first day. I regret that I didn't take his recommendation: Not to buy any D-link product!
And... Is D-link fixing the firmware?
I am the OP of this topic.
Of course, I have downgraded in order to get the cameras work again.
But it is not the way it should be.
I assume D-Link will release new STABLE firmware.
While new feature is a plus, security fix is much more important.
Yet, their recent 2 versions of firmware are buggy, making the cameras unusable.
How can I trust D-Link anymore?
Who will buy D-Link products anymore?
