As per the standard design all Wi-Fi equipments must share spectrum bandwidth which are spaced around multiple channels bands with other networks in the same operational environment. Many neighbouring WiFi devices sharing or overlapping a channel can slow down the performance of all Wi-Fi networks on that channel, and therefore utilizing a WiFi scanner to analyze and fix proper channel usage is highly advisable for optimal wireless performance.
We will be using free WiFi scanner and analyzer inSSIDer (available on Windows, Mac and Android platforms) to tackle this need for us. inSSIDer Wi-Fi network discovery tool conveniently visualizes all wireless hotspot’s in your devices range complete with information of there MAC address, encryption, signal strength and channel allowing users to troubleshoot numerous WiFi related issues.
The way WiFi channels work, one can make use of the information analyzed and visualized using inSSIDer to fine tune wireless bandwidth usage for maximum throughput and minimum interference as described ahead.
As you can see the way wireless bandwidth channels work, There are 14 channels designated in the 2.4 GHz WiFi range spaced 5 MHz apart with adjacent channels overlapping and interfering with each other. As evident from the diagram shared below, using channels 1, 6, 11 is recommended for the minimum overlapping and interference avoidance. A user must also make sure to use the least congested channel availble for best results.
Users in many countries are experiencing extremely slow internet connection since past few days, thanks to an major undersea sub-continental cable cut. The most affected countries include India, Pakistan and Egypt where internet connectivity to content hosted in Europe and US is almost unaccessible due to slow speeds.
Google Keep the newly announced service from tech giant, allows users to quickly jot down notes, voice memos with transcription support, reminders, checklists, ideas or anything else including photos to keep track of important things that matter. Your notes and data are safely stored on
