If your broadband doesn't feel up to scratch, you'd be wise to make a very simple Wi-Fi router check. Virgin Media has just issued some vital advice that not only makes sure your broadband stays safe but also keeps things running at full speed. The latest update from the telecoms giant basically ensures that your Wi-Fi is used only by you and no one else.

It can be pretty easy to forget who has access to the router's password and login details. Not keeping track of this information not only puts your connection at risk but can also slow things down.

"Think someone else might be using your WiFi? Learn how to spot the signs, check connected devices and secure your network to keep your broadband safe," Virgin explained.

Virgin says that even the fastest broadband can slow down if extra devices are connected to it. While these signs don't always mean a stranger is on your network, it's worth checking if you notice things such as slower speeds, frequent disconnections, password issues or the router behaving strangely.

If something feels odd, then a simple check will reveal exactly what is going on.

Virgin offers several ways to check whether the router is being hijacked by others. Firstly, you can log in to your Virgin Media Hub via the app or browser. Then you can look for a list of connected devices: any unfamiliar names may indicate unwanted users. If anything looks unfamiliar, it's worth investigating.

Another way to check is via MyVM app. This software shows all devices currently connected to your network. You can even block or manage devices straight from the app.

Someone using your WiFi? Here's what to do

Virgin has issued the advice, below, for anyone worried about their router.

If you think someone else has access to your network, don't panic, a few quick steps can help secure it.

Change your password: This is usually the fastest fix. Choose a strong password with a mix of letters, numbers and symbols. Changing it will automatically disconnect everyone from your network, so you'll need to reconnect your own devices.

Restart your router: Once you change the password, restarting your router disconnects all devices so only authorised ones reconnect.

Check your router's connected devices: Most routers make it easy to see what's connected. Log in to your Hub via the app or a web browser, then look for a list of devices. If you're unsure, turn devices off one by one or disable WiFi temporarily to see which ones are authorised.

Enable security features: Many routers and apps, including the Virgin Media Connect app, let you monitor your network and spot unusual activity automatically.
