Dell Small Business continues to offer the Trendnet AC1900 Dual Band 802.11ac Wireless Gigabit Router for $49.99 with free shipping. (Amazon charges the same.) That's tied with our mention from last week as the lowest price we've seen. (It's also the best deal we could find today by $20.) It features dual-band support, four Gigabit Ethernet ports, the ability to create an isolated guest network, and USB. Deal ends July 2.
