Im a pretty consistent gamer and with the rest of the family on the wifi it use to lag a lot. Switched to the Nighthawk AC2300 and I can't think of one time that I didnt have a strong connection while gaming. I should have bought one long ago.
I went through 2 of the free routers from Optimum Cable. They CONSTANTLY dropped the signal and the 5Ghz only worked sometimes. This router is a dream! Easy to set up and just simply works. We're hooked up to 18 devices. 3 laptops, 3 iphones, 2 Rokus, 3 Nintendo DS, 2 Kindle Fires, 1 Kindle Paperwhite, Wireless printer, Nintendo WiiU, Nintendo Switch, Playstation 3.
