If your home is plagued by Wi-Fi dropouts and other router issues, you may want to think about an upgrade, perhaps to one that offers multiple bands to up your choices and, with luck, performance.
Hence TP-Link's AC5400 Wireless Tri-Band MU-MIMO, also known as the Archer C5400 Gigabit Router. This sucker offers a total of six distinct networks, kind of: 1 x 2.4 GHz, and 2 x 5 GHz, with all three options available for both regular use or as specially noted "Guest" networks, so you won't get in trouble for some overnight interloper's porn downloads. Or whatever your issue may be.
