How to resolve the 'Weak Wi-Fi password' alert

This article explains how to resolve the issue if Network Inspector in AVG AntiVirus shows the following alert:

Weak Wi-Fi password

Description

If you see the alert above after running a Network Inspector scan, we have found that your Wi-Fi network is secured with a weak or default password. Anybody in range could easily guess your password and access your Wi-Fi network. This presents the following risks:

Additional devices connecting to your Wi-Fi network can affect the speed and reliability of your connection.
An attacker could use your Wi-Fi network to launch other attacks or commit crimes. If an attack is traced back to your network, you may be liable.
An attacker could connect to your Wi-Fi network and see private data that you send and receive, including your passwords, credit card info, and private messages and photos.

Solution

To resolve this issue, create a strong password for your Wi-Fi network, and all of the devices connected to it.

We recommend that you create a strong password using the guidelines below:

The password should contain at least 10 characters, but ideally 12 or more. The more characters you use, the more secure your password is.
The password should not be used to access any other accounts or services.
The safest passwords are phrases rather than single words. Select a phrase that is memorable for you, but not easily predictable.

Select your router brand for detailed instructions on how to secure your Wi-Fi network with a strong password:

Tips

To ensure that your Wi-Fi network remains secure, refer to the additional tips below:

Rename your Wi-Fi network if it uses a default network name (or SSID) that identifies the make of your router (for example, Linksys or NETGEAR). Identifying the make of your router makes it easier for hackers to break in.
Reveal any unwanted visitors on your Wi-Fi network by running regular Network Inspector scans. The scan results screen shows all of the devices that are currently connected to your network. After running the scan, you can also tick the box next to Enable notification of new devices on this network to ensure that you are notified each time a new device connects to your network.
We recommend that you do not configure your router to hide the name of your Wi-Fi network (or SSID). When your network name is invisible, your wireless devices broadcast the name themselves, which is even more dangerous.
We do not recommend using a MAC address access filter, as they are difficult to set up, and very easy to bypass.
Advanced users can change the subnet value from 192.168.0.x or 192.168.1.x to a value that is less common, such as 192.168.13.x. This increases security, because many attacks are performed by web snippets trying to access the most common values.
