With COVID-19 continuing to affect more countries around the world, many people are forced to stay home from work and schools are moving to distance learning. The frequency of using your home computer has increased significantly. If you have a laptop that supports 802.11n WLAN mode or if you have an 802.11n WLAN USB 2.0 device, you need to install or update the 802.11n WLAN driver to add support for Windows systems, like Windows 10, 8, 7, etc..
802.11n, an addition to the 802.11 family of standards, is a wireless network specification that uses multiple antennas to increase the WLAN speed. To experience a high speed and smooth surfing with the wireless, you can follow the 4 common ways below to update your 802.11n drivers for Windows 10, Windows 8.1, Windows 8, Windows 7, Windows Vista or Windows XP.
IEEE 802.11n-2009 or 802.11n is a wireless-networking standard that uses multiple antennas to increase data rates. The Wi-Fi Alliance has also retroactively labelled the technology for the standard as Wi-Fi 4.[8][9] It standardized support for multiple-input multiple-output, frame aggregation, and security improvements, among other features, and can be used in the 2.4 GHz or 5 GHz frequency bands.
As the first Wi-Fi standard that introduced MIMO (Multiple-Input and Multiple-Output) support, sometimes devices/systems that support 802.11n standard (or draft version of the standard) are being referred to as MIMO (Wi-Fi products), especially before the introduction of the next generation standard.[10] The use of MIMO-OFDM (Orthogonal Frequency Division Multiplexing) to increase the data rate while maintaining the same spectrum as 802.11a was first demonstrated by Airgo Networks.[11]
IEEE 802.11n-2009 is an amendment to the IEEE 802.11-2007 wireless-networking standard. 802.11 is a set of IEEE standards that govern wireless networking transmission methods. They are commonly used today in their 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac and 802.11ax versions to provide wireless connectivity in homes and businesses. Development of 802.11n began in 2002, seven years before publication. The 802.11n protocol is now Clause 20 of the published IEEE 802.11-2012 standard.
IEEE 802.11n is an amendment to IEEE 802.11-2007 as amended by IEEE 802.11k-2008, IEEE 802.11r-2008, IEEE 802.11y-2008, and IEEE 802.11w-2009, and builds on previous 802.11 standards by adding multiple-input multiple-output (MIMO) and 40 MHz channels to the PHY (physical layer), and frame aggregation to the MAC layer.
Channels operating with a width of 40 MHz are another feature incorporated into 802.11n; this doubles the channel width from 20 MHz in previous 802.11 PHYs to transmit data, and provides twice the PHY data rate available over a single 20 MHz channel. It can be enabled in the 5 GHz mode, or within the 2.4 GHz mode if there is knowledge that it will not interfere with any other 802.11 or non-802.11 (such as Bluetooth) system using the same frequencies.[14] The MIMO architecture, together with wider-bandwidth channels, offers increased physical transfer rate over 802.11a (5 GHz) and 802.11g (2.4 GHz).[15]
The 802.11n draft allows up to 4 4 : 4. Common configurations of 11n devices are 22:2, 23:2, and 32:2. All three configurations have the same maximum throughputs and features, and differ only in the amount of diversity the antenna systems provide. In addition, a fourth configuration, 33:3 is becoming common, which has a higher throughput, due to the additional data stream.[16]
Assuming equal operating parameters to an 802.11g network achieving 54 megabits per second (on a single 20 MHz channel with one antenna), an 802.11n network can achieve 72 megabits per second (on a single 20 MHz channel with one antenna and 400 ns guard interval); 802.11n's speed may go up to 150 megabits per second if there are not other Bluetooth, microwave or Wi-Fi emissions in the neighborhood by using two 20 MHz channels in 40 MHz mode. If more antennas are used, then 802.11n can go up to 288 megabits per second in 20 MHz mode with four antennas, or 600 megabits per second in 40 MHz mode with four antennas and 400 ns guard interval. Because the 2.4 GHz band is seriously congested in most urban areas, 802.11n networks usually have more success in increasing data rate by utilizing more antennas in 20 MHz mode rather than by operating in the 40 MHz mode, as the 40 MHz mode requires a relatively free radio spectrum which is only available in rural areas away from cities. Thus, network engineers installing an 802.11n network should strive to select routers and wireless clients with the most antennas possible (one, two, three or four as specified by the 802.11n standard) and try to make sure that the network's bandwidth will be satisfactory even on the 20 MHz mode.
PHY level data rate does not match user level throughput because of 802.11 protocol overheads, like the contention process, interframe spacing, PHY level headers (Preamble + PLCP) and acknowledgment frames. The main media access control (MAC) feature that provides a performance improvement is aggregation. Two types of aggregation are defined:
Frame aggregation is a process of packing multiple MSDUs or MPDUs together to reduce the overheads and average them over multiple frames, thereby increasing the user level data rate. A-MPDU aggregation requires the use of block acknowledgement or BlockAck, which was introduced in 802.11e and has been optimized in 802.11n.
When 802.11g was released to share the band with existing 802.11b devices, it provided ways of ensuring backward compatibility between legacy and successor devices. 802.11n extends the coexistence management to protect its transmissions from legacy devices, which include 802.11g, 802.11b and 802.11a. There are MAC and PHY level protection mechanisms as listed below:
To achieve maximum output, a pure 802.11n 5 GHz network is recommended. The 5 GHz band has substantial capacity due to many non-overlapping radio channels and less radio interference as compared to the 2.4 GHz band.[18] An 802.11n-only network may be impractical for many users because they need to support legacy equipment that still is 802.11b/g only. In a mixed-mode system, an optimal solution would be to use a dual-radio access point and place the 802.11b/g traffic on the 2.4 GHz radio and the 802.11n traffic on the 5 GHz radio.[19] This setup assumes that all the 802.11n clients are 5 GHz capable, which is not a requirement of the standard. Quite a few Wi-Fi-capable devices only support the 2.4 GHz and there is no practical way to upgrade them to support 5 GHz. Some enterprise-grade APs use band steering to send 802.11n clients to the 5 GHz band, leaving the 2.4 GHz band for legacy clients. Band steering works by responding only to 5 GHz association requests and not the 2.4 GHz requests from dual-band clients.[20]
After the first draft of the IEEE 802.11n standard was published in 2006, many manufacturers began producing so-called "draft-n" products that claimed to comply with the standard draft, even before standard finalization which mean they might not be inter-operational with products produced according to IEEE 802.11 standard after the standard publication, nor even among themselves.[22] The Wi-Fi Alliance began certifying products based on IEEE 802.11n draft 2.0 mid-2007.[23][24] This certification program established a set of features and a level of interoperability across vendors supporting those features, thus providing one definition of "draft n" to ensure compatibility and interoperability. The baseline certification covers both 20 MHz and 40 MHz wide channels, and up to two spatial streams, for maximum throughputs of 144.4 Mbit/s for 20 MHz and 300 Mbit/s for 40 MHz (with short guard interval). A number of vendors in both the consumer and enterprise spaces have built products that have achieved this certification.[25]
Wi-Fi device band selection: Windows 10 can perform Miracast overboth the 2.4GHz and 5GHz bands and works well with an 802.11n or802.11ac capable Wi-Fi adapter. The 5GHz band, however, offers higherbandwidth and more channels with less interference, ideal conditions for a higher quality stream. Therefore, solutions supporting multi-band are recommended.
Wi-Fi Antennae configuration: Typically, an 802.11ac radio using the5GHz band and a 2x2 antennae configuration produces a higher qualityMiracast experience than any 802.11n or 1x1 combination. Solutions supporting 2x2 antenna configurations are recommended.
Wi-Fi Driver Type: Ensure that Wi-Fi adapter manufacturers providedrivers specifically designed for the Windows 10 Wireless DriverInterface (WDI). Wireless drivers developed for the WDI framework areprecisely designed for Miracast usage. These drivers successfully demonstrate higher connection rates and yield high-quality Miracastsessions. 041b061a72
