Nikon offers a wireless LAN adapter for a hefty price of nearly 700 euros for the D810. I have simply considered insolence and looked around in the market for alternatives. The TP-Link TL-MR3040 V2.3 wireless router +++ Photecs edition I have found a great alternative. The price is more than reasonable and with the appropriate app for my phone does the solution excellently. In addition, I can remotely control my D7100 with the router, with a much higher speed than with the original accessories that are priced reasonably compared to the price of just 50 euros. By the way also is a joke, what Nikon wants for the MB-D12 grip.
