Amazon offers the D-Link Dual Band AC1900 802.11ac Wireless Gigabit Router for $79.99 with free shipping. (Newegg charges the same.) That's tied with last month's mention as the best price we've ever seen; it's a low now by $20. This router features speeds up to 600 + 1300 Mbps on both 2.4GHz and 5GHz channels, four Gigabit Ethernet ports, and advanced AC SmartBeam technology.

Note: It's expected to ship in one to two months.
