newegg offers the factory-refurbished Linksys by Cisco 802.11n Wireless 4-Port Router, model no. WRT120N, with an Service Net extended 1-year warranty for $16.99 plus $1.99 for shipping. That's $6 over our mention of a refurb from three weeks ago, but that deal had rebate hassles and no extended warranty. (It's currently $27 under the lowest total price we could find for a new unit.) This router features four Ethernet ports and both WPA2 and WEP security. A 90-day Cisco warranty applies on top of the Service net warranty.

Note that the extended warranty is invalid in Florida, New Mexico, and Oklahoma.
