Newegg offers the D-Link Dual Band AC1900 802.11ac Wireless Gigabit Router for $79.99 with free shipping. (Amazon charges the same.) That's tied with our mention from three weeks ago as the best price we've seen; it's a low now by $13. 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: This item ships in two to three weeks.

Update: It's now out of stock at Newegg, but Amazon still charges the same price.
