Newegg offers the refurbished ASUS Dual-Band 802.11n WiFi Gigabit Ethernet 3-in-1 Access Point / Wireless Bridge / Range Extender, model no. EA-N66, for $49.99. Coupon code "EMCWPHB72" cuts it to $29.99. With free shipping, that's tied with last month's refurb mention and $34 below the lowest total price we could find for a new device. It features an orthogonal 3x3 antenna design. Deal ends November 3.
A 90-day warranty applies, but it's unclear who backs it.
