Digital Etc. via Amazon offers Amazon Prime members the factory-refurbished Cisco Valet 802.11n Wireless Router, model no. M10, for $21 with free shipping. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $6.17.) That’s tied with our mention from two weeks ago as the least expensive Cisco Valet wireless router we’ve ever seen. (It’s a current low for this refurb by $14.) This router features four 10/100 ports, WEP, WPA2, and WPA-PSK encryption, parental controls, easy setup USB key, and more. Note: No warranty information is provided.
