Newegg offers the refurbished D-Link AC Smartbeam 802.11ac Wireless Gigabit Router, model no. DIR-868L, for $56.99 with free shipping. That's $3 under our mention from three weeks ago and an all-time price low for a single purchase. (It's also $88 less than the best price we could find for a new one.) It features 2.4GHz and 5GHz frequencies, four Gigabit Ethernet ports, and WPA2 encryption.

A 90-day warranty applies, but it's unclear who backs it.
