Newegg offers the refurbished Netgear AC1750 Dual-Band 802.11ac Wireless Router, model no. R6300-100NAR, for $99.99. Apply coupon code "MASTERPASS" and checkout via Masterpass to drop it to $89.99. With free shipping, that's tied with our refurb mention from two weeks ago and $80 less than the lowest total price we could find for a new one. The dual-band (2.4GHz and 5GHz) wireless router features wireless speeds of up to 450Mbps and five Ethernet ports.
A 90-day warranty applies, but it's not clear who backs it.
