In many ways, it’s great news that wireless Internet access is becoming more accessible. But the proliferation of WiFi hotspots also has some negatives. The WiFi radio spectrum is divided into several channels.
When too many WiFi hotspots broadcast on the same channel, traffic congestions may occur, and data packets may get lost, leading to connection drops and poor speeds.
The solution is to use a WiFi channel with the least amount of traffic. But how can you tell which channel that is? The answer is simple: you download and use a WiFi analysis tool. When it comes to WiFi analysis, there are comprehensive solutions for Windows and Mac computers, such as NetSpot, which can build a comprehensive heatmap of your network and tell you everything you need to know about WiFi activity in your area.Launch the program and it scans the airwaves, displaying a table with details on any local access points: SSID, MAC Address, Vendor, type, RSSI, channel, 802.11 (a/b/g/n/ac), security details (WEP/WPA/WPA2/WPS), and when they were first and last seen.
In addition, a Signal Strength chart plots the strength of each signal over time, while "2.4GHz APs" and "5GHz APs" charts graphically show their channel usage. Reporting options are mostly reserved for the commercial edition, although bizarrely you can tweet a screenshot in a click or two, which might be useful if you’re working on an issue with someone else.Ī built-in Connectivity module runs brute-force testing on your chosen network against a sample dictionary of common passwords. We wouldn’t recommend you use this to hack your neighbors - there’s no telling what alarms you might set off - but it’s an easy way to make sure your own systems aren’t using the most obvious passwords. There’s also an optional Monitor Mode which uses Acrylic’s own driver to monitor network packets and may help you identify hidden networks. The Home version of Acrylic Wi-Fi is free for personal use and has enough to show a signal strength graph for monitoring or troubleshooting. Acrylic Wi-Fi Heatmaps As one of the most advanced WiFi analysis solutions on the market, Wi-Fi Heatmaps from Acrylic is an Enterprise level package in a league of its own. Is Acrylic WiFi Free really "the most advanced WLAN Scanner"? Well, no. Buy Arylic WiFi & Bluetooth Home Amplifier,STA326 with 50+50W 24V DC/2. Password testing and Monitor Mode are pluses, though, as might be the Twitter integration for some people. Although if you don’t need the extras or graphical glitz, NirSoft’s WifiInfoView actually displays more information, is portable, runs on Windows Vista or later, and is free for all uses.
