Cox has increased their internet speed in my area but advises me that I need to upgrade to a DOCSIS 3.0 modem to take advantage of the enhancement. I plan to purchase a Motorola sb6141 modem for that purpose. I also have a D-Link DIR-825 wireless router connected to the modem. Will I need to upgrade the router so wi-fi connected devices will be able to take advantage of the enhanced speed? If so, what router do you recommend?
