I didn't really notice in the past, only recently did I begin to experience an interference on a fire stick on WIFI. It took a spectrum analyzer to figure out my microwave oven was on it's way out and was creating an harmonics in the middle of the WIFI band.
Took a couple weeks of troubleshooting to get to the real cause. Posted 19 April - AM. Okay so I rearranged my room today and for the first time I'm getting max speeds whereas on the other end of the room I kept getting dropouts which makes me believe there's a grey zone right there for speeds since it was slow. This time, however I uninstalled the drivers and let the ones from Windows install instead.
As soon as I install the drivers from the website I keep getting disconnection messages all over the place, this is the second thing that contributed to the dropouts.
Posted 19 April - PM. So I ran a test last night and the 1st problem is happening again but I am still getting full speeds. Posted 24 April - AM. This is not the greatest HOWTO for nslookup, but it should tell you what you need to do simple tests:. Community Forum Software by IP. Sign In Create Account.

Countries such as Japan use different frequencies but the router manufacturer includes the ability to make changes to widen their sales market. I am not positive as to what these settings do but the most likely function is to give these applications a higher CoS value priority over normal packets. Open its software utility. Usually the channel adjustment is in the advanced configuration settings.
BOTH my wireless router and wireless adapter have the adhoc channel adjustment. April 7 61 Report. Beamforming or TxBF is an optional feature in the Beamforming includes explicit Beamforming and implicit Beamforming. Explicit Beamforming requires the receive end to send information about the received signal to an AP. The AP then adjusts the transmit power to the optimal value according to the signal information. This function increases the SNR of the receive end and improves the receiving capability.
Implicit Beamforming allows an AP to automatically adjust the transmit power to increase the SNR of the receive end based on channel parameters without requiring the receive end to work with the AP.
Currently, mainstream terminals do not support Beamforming. The key benefits of beamforming are: 1. Reduce dead spots. Deliver stable Wi-Fi connection for voice and HD video. Better Wi-Fi throughput 4. Reduces unnecessary RF interference. EnableAdaptivity : Will try to change frequency if it detects WiFi noise. Disable it, if you are relatively closer to the router OR if there are not many WiFi networks around. The data stream is transmitted on multiple antennas so the receiving system has a better chance of detecting at least one of the data streams.
Space time block coding STBC transmits multiple copies of one data flow in wireless communication. STBC uses many antennas to produce multiple receive versions of data, improving data transmission reliability.
Among these data copies, optimal copies are combined to provide most reliable data. This redundancy increases the chance of using one or more copies of received data to correctly decode the received data. STBC combines all the copies of received signals to produce the useful data. In effect, STBC transmits the same data stream twice across two spatial streams so that a receiver that misses a data block from one spatial stream has a second shot at decoding the data on the second spatial stream.
Antenna Diversity Type A wireless technique that uses multiple antennas to receive or transmit signals along different propagation paths to compensate for multi-path interference. Useful, if available. I note that ALFA says your adapter contains some kind of anti-Bluetooth-interference device, which is probably what this is all about.
It probably has a stripped-down Bluetooth radio that simply tells other Bluetooth radios to stop using the frequencies that its Wi-Fi radio is using. Channel : Controls the channel your AP uses to communicate with client devices on your Wi-Fi network.
Most APs should have this set to Auto by default. Some newer or higher-end APs are capable of operating at multiple bands or channels at the same time. For example, you may configure the AP to use Channel1 2.
For optimal performance and compatibility, enable support for all channel widths. Auto : Enables all Wifi technology supported by the adapter. For optimal performance and compatibility, enable support for all wireless modes. IEEE Dual Band The MIMO technology allows spaces to become the resources used to improve performance and increases the coverage range of the wireless system. The MIMO system generates multiple spatial flows with each antenna generating a maximum of one spatial flow.
The single in single out SISO system sends or receives one spatial flow one copy of signals at a time. The MIMO technology allows multiple antennas to send and receive multiple spatial flows multiple copies of signals simultaneously and to differentiate the signals sent to or received from different spaces.

I was hoping someone could summarize what is meant by the properties: IEEE Improve this question. Greenonline 1, 4 4 gold badges 15 15 silver badges 27 27 bronze badges.
