So I am going to get TimeWarner's 200 mbps internet and I have e2500 wifi router right now. This router has 10/100 WAN port but has N wifi. Does this mean I can only use 100 mbps of the internet? If yes, why are they saying wifi will support 300 + 300 mbps of speed in their spec? Is this just for when transferring file via wifi in local computers (LAN)? If I want to use all 200 mbps, Do I need to get wifi router with gigabit WAN port?
