@TP-Link I think you need to rethink having the USB restricted just for the 3g/4g dongle if it was costing 70-80 pounds and it was being purchased for a small to medium business that would be perfectly valid and acceptable but the price of the TD W9970 is more for the home market and so the device I would of thought be better being an all rounder for me I'll be returning mine and going for another make you've lost a loyal customer.
