Walmart offers the refurbished Cisco Linksys 802.11n Wireless-N300 4-Port Router
, model no. E900, for $12
for shipping. That's a buck under our fall mention of a refurb and the lowest total price we could find by $6. It features four 10/100 Mbps Ethernet ports, a data transfer rate of 300 Mbps, and WPA2 and WEP security.
A 90-day warrantly applies, although its unclear who backs it.
