Newegg offers the factory-refurbished D-Link AC1200 Dual-Band 802.11ac Wireless Gigabit Ethernet Router, model no. DIR-850L, for $29.99 with free shipping. That's tied with our mention from three weeks ago as the best price we've seen for this model in any condition. (It's also $45 under the lowest total price we could find for a new one today.) The dual-band (2.4GHz and 5GHz) wireless router features wireless speeds of up to 1,200Mbps and four Gigabit Ethernet ports.
A 90-day D-Link warranty applies.
