Newegg offers the TP-Link Archer C3150 Dual Band 802.11ac Wireless Gigabit Router for $89.99 with free shipping. That's $6 under our mention from last March and the lowest price we've seen. (It's also the best deal we could find today by $45.) The router features 4-Stream and NitroQAM technology for speeds up to 3,150Mbps, a 1.4GHz dual-core processor, four Gigabit Ethernet ports, USB 3.0, and four external antennas.
