I have a BSNL fiber connection that is of 200 mbps speed. However the default modem provided gives only maximum around 100mbps via wifi but almost full via LAN (around 180 and 190). So i need suggestion for buying a router that can provide the max speed without limiting at 100mps via wifi. BSNL customer care just suggested buying a dual band router. Checking on amazon i saw hell lot of options and i really don't know which one will be good. Attached is the image of the BSNL modem i am using.
