The quad stream NETGEAR AC2600 Nighthawk X4S R7800 802.11AC wireless router is the successor to last year's AC2350 Nighthawk X4 R7500 (and R7500v2). Besides a bump in ?S?, for Smart, the Nighthawk X4S also jumps to the dual-core 1.7GHz Qualcomm IPQ8065, adds 200MHz of theoretical bandwidth to the 2.4GHz radio (800MHz + 1733MHz = AC2600) by increasing to 4x4 in both bands, and enables 160MHz channel width for 5GHz. Priced at $270/£230 SRP ($260/£213 street) the Nighthawk X4S R7800 looks to be a solid contender for the mid-range performance 802.11AC router market, and with Wave 2 features like MU-MIMO enabled out-of-the-box (OOTB) a fair degree of future proofing.
