What is BSSID in Router?
The BSSID is the unique ID for the network provided by a radio in the wireless router or access point. This network is known as the Basic Service Set, hence the name BSSID.
Is CWNA a good certification?
CWNA is the only vendor-neutral certification recognized worldwide by wireless vendors and consultants and provides a wealth of foundational knowledge related to wireless network functionality and operations.
How do I disable Fat channel intolerance?
Fat channel intolerance is typically set on end devices such as laptops and other wireless clients. If it can be disabled, it will be in the driver settings; however, it is not wise to use 40 MHz channels in the 2.4 GHz band unless you are isolated from other networks.
How do I find my WIFI Essid?
There is technically no concept of an ESSID within the 802.11 standard that defines Wi-Fi. However, each BSS will have a BSSID, which can be seen in Beacon frames transmitted from the wireless router or AP.
Is IEEE 802.11 and Wi-Fi same?
Wi-Fi is the trademark of the Wi-Fi Alliance that defines the features of 802.11 that they test and certify in evaluated devices. Technically, 802.11 offers more than that which is required of Wi-Fi.
What is Airtime Fairness?
Airtime Fairness is a non-standard solution that attempts to ensure that devices with higher data rates get equal time as devices with lower data rates. The result is greater aggregate throughput in the network, but less throughput for the low data rate clients.
What is Wi-Fi TxBF?
TxBF stands for Transmit (Tx) Beamforming (BF) and it is a technology that uses multiple antennas and RF wave manipulations to increase the received signal strength at a given receiver.
What is OSI model?
The Open System Interconnect (OSI) Model is a 40-year-old model of how network communications work. It separates the communications into seven layers and describes the services and functions provided by those layers. It is mostly a thinking and educational tool today as the TCP/IP model does not link directly to it; however, it is still of significant value for understanding how network applications and devices work.
What is WiFi Strength and RSSI?
RSSI is the Received Signal Strength Indicator and it is a measurement of Wi-Fi signal strength. The signal strength is, quite literally, the power level of the signal. A higher level allows for better signal reception and therefore higher data rates. There is a technical definition of RSSI in the 802.11 standard, which varies somewhat from other wireless networking standard definitions, but it has become commonly used to simply reference the power level of the signal (typically defined in dBm or decibels related to milliwatts).
What is QAM WiFi?
Quadrature Amplitude Modulation (QAM) is a radio frequency wave modulation method that uses both the amplitude (strength of the wave) and phase (relation of the wave to previous waves) to represent data bits. It is used in all modern Wi-Fi networks, including the newest 802.11ax or High-Efficiency wireless.
