So I have Airtel Fiber, 200Mbps with unlimited data. My house isn't very large but has badly placed wireless landlines which limit the NOKIA modem/router they provided. I have taken a LAN cable from the NOKIA router to the other corner of the house where I have a D-Link router which I connected it too but it caps the WiFi speed and Lan speed through the router at a 100Mbps. The model number is DIR816 and I'd like to upgrade it to whatever can give me full speed through LAN and WiFi on the new router. What are the 'specs' it'll need to do so? Any routers you'd recommend? Not looking for anything fancy, basic consumer grade and cheap works for me, its just for 2 rooms.
