As one of its daily deals, Newegg offers the refurbished Asus 802.11n Wireless Dual Band Gigabit Router, model no. RT-N66R, for $54.99 with free shipping. That's $5 under our refurb mention from three days ago and the lowest total price we've seen. (It's also $65 below the best price we could find for a new one.) This router features data transfer rates of up to 900Mbps, USB, four LAN ports, and DD-WRT open source support. Deal ends today.
Note: A 90-day warranty applies, although it's unclear who backs it.
