Thanks for getting back to us, how about this:
- Could you provide the firmware version for both units?
D-Link USA does not support issues from outside our region, in this case, we don't even market the DSR-1000 in our region, so we can't test with the exact hardware, but we do market the other models in the DSR family and may help you check on the issue, assuming we can find the correct version of the firmware on any of the other DSR models. We fully support our DSP family of products, so no problems there.
I suggest you keep putting pressure on your regional D-Link support team until you get better results. Ask to be escalated to at least a Level 3 support agent.
