Newegg offers the TP-LINK 802.11n Wireless 4-Port Gigabit Ethernet Broadband Router, model no. TL-WR1043ND, for $48.99. Coupon code "EMCPBHD48" drops it to $39.99. With free shipping, that's the lowest total price we could find by $5 and the best price we've seen without rebate hassles. (We saw it for $15 less last year after a rebate.) It features four ports, three detachable antennas, a USB port, and more. It's also compatible with DD-WRT, a Linux-based alternative OpenSource firmware. Deal ends September 1.
