Newegg offers the refurbished TP-Link AC1750 Dual-Band 802.11ac Wireless Gigabit Router for $34.99 with free shipping. That's $10 less than our October mention and $55 below the lowest price we could find for a new unit. It features one USB 3.0 port, one USB 2.0 port, three detachable antennas, and simultaneous 2.4GHz and 5GHz frequencies up to 450MB/s and up to 1,300MB/s, respectively. Deal ends October 22.

Note: A 90-day warranty applies, although it's unclear who backs it.
