BT has announced a raft of new features for its Whole Home Wi-Fi system, similar to those already offered by Google's Wi-Fi device.
Users of the enhanced Whole Home app will be able to set time limits for how long certain devices can stay connected to the internet.
These limits can be applied to all of the devices belonging to a particular user, as well as individual devices.
A smart scheduling feature has also been launched, which allows internet access to be restricted at bedtimes, while the time settings can be varied for different days of the week.
These features could be particularly useful for parents that want to restrict their children's online activity.
BT is also giving Whole Home Wi-Fi users the option of adding a guest network, so visitors can use an independent name and password to get online, while the BT customer can be confident that their devices and content on their personal Wi-Fi are secure.
Access to the guest network can be scheduled, so it can only be accessed at selected times, while people will also have the option of blocking devices they do not recognise.
Erik Raphael, director of BT Wi-Fi, Devices and BT Shop, commented: "These updates make life easier for our customers.
"Being able to control Wi-Fi access at mealtimes and bedtimes is great for family life and even your friend can benefit from a separate guest network that’s easy to access."
The BT Whole Home Wi-Fi system was launched last year to tackle the problem of Wi-Fi deadspots around the home, ensuring a reliable signal gets to hard-to-reach areas such as basements and attics.
The system comprises three disc-shaped Wi-Fi repeaters, which are about the size of a small frisbee, that extend the coverage area of a home's Wi-Fi network.
