WiFi scanners are informative software that elevates the security level of your wireless connection.
This kind of software provides information about WiFi problems, the best channel for your router, the best place for installing the router by turning your PC or your laptop into an analyzer for the wireless network.
Most of them have features like: showing all the networks that may interfere with your connection, checking your WiFi connection speed and health, refining found network results with filters, and many more.
Also, in the current market are plenty such programs but not up to the standards of an ordinary user or they may even create a breach in the security system of your connection.
To avoid the disappointment of searching a program of this kind, we have prepared for you a list with the best WiFi scanners available nowadays.
This tool is developed by one of the biggest network security company in the world. It will let you maintain an overview of all your devices that are connected to a wireless network.
It will help you check the speed, load, traffic, status, signal strength of your routers. Basically, it is your best friend when you need to check what’s happening on your Wi-Fi pipes.
First, of all, PRTG will allow you to see when your routers are not available so you could fix this and re-establish the Wi-Fi connection.
This is a crucial factor for a network with multiple devices connected for sync or sharing purposes, even if it is only your home network and the connected devices are your laptop/PC, tablet, and phone.
You will also be able to see when your network is too loaded so you could avoid disruptions. Just keep an eye on the bandwidth markers from PRTG and see what device and what app is consuming most of your connection.
One of the most needed features is to see where the Wi-Fi connection is lacking strength.
If a router has some problems with its emitters, then you will be able to see it on the software‘s dashboard and you will be good to change/fix that router or any other problematic element of your network.
Another crucial feature is seeing the last access to a device. It is really useful to monitor what device from the network accessed the Wi-Fi during the night or when normally there shouldn’t be any access.
This will help you remove the unneeded devices that are consuming the internet and bandwidth.
You can try this program for 30 days and you can go on the free (but limited) version after that or you can continue by upgrading to a pro plan.
