NETGEAR has announced an ADSL modem combo version of its popular AC1900 router.
The D7000 Nighthawk AC1900 WiFi VDSL/ADSL Modem Router is an AC1900 class router with built-in ADSL/ADSL2/ADSL2+/ VDSL/VDSL2 modem, Gigabit Ethernet ports and two USB 3.0 storage and printer sharing ports.
The NETGEAR D7000 is available now throughout Europe, Asia and Australia at an MSRP of €229.99 (EUR). It will be available in early fall in the U.S. at an MSRP of $249.99.
EnGenius has added three 802.11ac access points.
D-Link has announced a combo ADSL2+ / 802.11n wireless router.
SmallNetBuilder has discovered a hole in the Wi-Fi Alliance's 802.11n Draft 2.0 test suite that can allow Wi-Fi Certified products to interfere with existing wireless networks, in direct violation of a mandatory Certification requirement.
A long-running battle in the standard has been whether to allow the use of "wide-channel" operation in the 2.4 GHz band that is used by the majority of Wi-Fi products. The mode, also referred to as "channel bonded" or "40 MHz bandwidth" mode, uses up two of the available three non-overlapping channels in the band, making it impossible to avoid interfering with other wireless networks operating in the center of the band.
Interference from draft 802.11n channel-bonded networks can, at worst, render 802.11b and g wireless networks inoperable and, at minimum, cause slowdowns and unreliable connections.
