DigiTimes reported today that D-Link has cut the price of "entry-level" draft 802.11n routers in the U.S. market to under $50.
The reason for the price cut is to "drive shipments of its 802.11n products up to its goal of two million units set for this year".
As of this morning, Pricegrabber is showing a price of $49.99 for the DIR-615 Wireless N Router at Circuit City and Best Buy.
Digitimes reports that the three leading consumer networking device vendors are holding the line on product prices this holiday season.
D-Link, Linksys and Netgear have mostly kept the price of consumer networking devices—especially 802.11n products—unchanged, instead of resorting to more aggressive pricing to boost sales during the year-end peak season, according to industry sources.
The article said that the companies are still looking for indications of how strong demand will be for holiday buying and said that consumers "may start seeing discount offers from the vendors in early 2008 if sales do not pick up as expected in the following weeks".

Buffalo Technology has issued an official statement about its battle with Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO).
Visitors to the Wireless Products section of Buffalo's website are now redirected to a page that states "Buffalo cannot offer for sale, sell, import, or use its IEEE 802.11a and 802.11g compliant products in the United States". Existing inventory can still be sold and in-warranty defective products can be replaced.
CSIRO filed suit against Buffalo in February 2005 and in June 2007 won an injunction preventing sales of all Wi-Fi products. CSIRO is defending its U.S. Patent No. 5,487,069 that contains claims related to key technologies used in 802.11a, and g wireless standards.
Buffalo is currently awaiting the results of its appeal requesting a reversal of the decision and a stay of the injunction.
Cisco today said it has a definitive agreement to purchase Navini Networks, described as "a leader in the Mobile WiMAX 802.16e-2005 broadband wireless industry".
Cisco's announcement noted Navini's "Smart Beamforming" MIMO antenna technology as one of the reasons for the acquisition. Navini also brings to the table a portfolio of broadband wireless WiMAX solutions including base stations, adaptive antenna arrays, management systems, and subscriber modems, as well as a base of 75 customers.
Under the terms of the agreement, Cisco will pay approximately $330 million in cash and assumed options. The Navini acquisition is expected to close in the second quarter of Cisco's 2008 fiscal year. Upon the close of the acquisition, Cisco plans to integrate Navini into its Wireless Networking Business Unit, under the Ethernet and Wireless Technology Group.
Linksys today announced the first of its Ultra RangePlus wireless networking products.
The Ultra RangePlus Dual-Band Wireless-N Gigabit Router (WRT600N) and Dual-Band Wireless-N Notebook Adapter (WPC600N) are 802.11n Draft 2.0 Wi-Fi Certified and operate in the 2.4 GHz and 5 GHz Wi-Fi bands. The WRT600N has two radios for simultaneous dual-band coverage. Both products are based on Broadcom Intensi-Fi draft 11n chipsets.
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.
DigiTimes today said that D-Link has revealed its WiMax product strategy and plans for European rollout of draft 802.11n products.
