Today only, B&H Photo Video offers the TP-Link AC1200 Dual-Band 802.11ac Wireless Range Extender for $24.99 with free shipping. That's tied with our mention from last December as the lowest price we've seen. (It's the best deal now by $31.) It boosts your wireless coverage up to 10,000 sq. ft. and features two external antennas and a Gigabit Ethernet port.
