recently buying the DIR-X3000Z from D-Link official store at Lazada for mesh with my Unifi dir-x3060z via cable. Speedtest is ok and can up to 800mbps, but when I downloading heavily with lot of connection , it will randomly disconnect and reboot. Tot it was individual faulty product and request return/refund. After refund, buying back the same product from the same store again and the same problem occur. Is this product cannot use for downloading? Previously I using tenda to link with unifi dir-3060z at downstairs, I have no problem with downloading ,just it can't mesh so have 2 different ssid which is not so convenient and tenda is ax1200 only which has lower speed. I try also downloading with the original tm dir-x3060z, it has no problem with downloading heavily also and can achieve 800mbps with wifi. So, only the retail version of D-Link dir-x3000z has problem of disconnecting and reboot when downloading heavily that is really suck.
