FIRST LOOK: Gigabit Wi-Fi adapters

New 802.11ac USB-based adapters allow users to speed up Wi-Fi links on existing devices
  • 1 of 8

At some point, desktops and laptops will come with the new Gigabit Wi-Fi standard 802.11ac built in. But if you can’t wait and want to speed up the wireless links on your existing devices, you can buy an 802.11ac adapter today. We tested USB adapters from Netgear (two different models), Edimax, ZyXEL, and TRENDnet, plus a PCI Express card from ASUS. The USB adapters range in price from $40 to $70, while the ASUS card sells for around $100. All the adapters provide dual-band connectivity, supporting 802.11b/g/n in the 2.4GHz frequency band and supporting 802.11a/n/ac in 5GHz BAND. The Netgear A6200 uses the finalized 802.11ac standard and is Wi-Fi Certified. The others are all using draft versions. (Read the story version.)
