Walmart offers the TRENDnet 802.11n Wireless Router, model no. TEW-711BR, for $7.99. Opt for in-store pickup to dodge the $4.97 shipping fee. (
Amazon also charges the same with free shipping for Prime members.) Although we saw it for $4 less in August with a rebate, this is the best price we've seen without rebate hassles. (It's also a current low by $5.) It features up to 150Mbps data transfer rate and four Ethernet ports.
