Linksys offers its refurbished Linksys AC1600 Smart Dual-Band 802.11ac Wireless Router for $29.99 with free shipping. That's $32 under the lowest price we could find for a new unit, although we saw a refurb for $10 less June. This dual-band (2.4GHz and 5GHz) wireless router features wireless speeds of up to 1,300MB/s and four Gigabit Ethernet ports.

Note: A 90-day Linksys warranty applies.
