Today only, Amazon offers its Prime members the TP-LINK 802.11n Wireless 4-Port N300 Broadband Router, model no. TL-WR841ND, for $14.99 with free shipping. (Non-members can spend $35 or more to bag free shipping; otherwise it adds $8.79.) That's tied with our Black Friday week mention (which required a rebate) as the best price we've seen. (It's a current low by $3.) It features two detachable antennas.
