Newegg offers the ASUS Dual-Band Wireless N900 Gigabit 3-in-1 AP/Bridge/Range Extender, model no. EA-N66R, bundled with a Total Defense Premium Internet Security 5-User for Windows for $79.99. Mail-in rebates for $20 and $50 drop it to $9.99. With $2.99 for shipping, that's $65 under the lowest total price we could find for a new adapter alone. It features WEP, WPA, and WPA2 encryption. Deal ends July 31.

A 90-day warranty applies, although it's unclear who backs it.
