Virgin Media customers have been told that the company is to expand its wi-fi network, with hubs being added to homes to work as wi-fi hotspots for other Virgin Media customers.
A letter sent to customers this month says that Virgin wants users who are on the move to have internet access in 'as many areas as possible'.
But what exactly does this mean? Will it slow down your connection, is it safe and can you opt out? We run through the small print below.
An update rolling out to Virgin Media hubs means that they'll act as hotspots, to give phone users access to free public wi-fi. Virgin says that there are currently more than 2m hotspots in the UK, and it plans on expanding over the coming months.
The Virgin Media wi-fi mobile app (right) lets broadband customersup and down the country connect to hotspots. If you're out and about and in desperate need of a wi-fi signal, the free mobile app is there to lend a helping hand.
By default, Virgin Media customers are signed up to the scheme and therefore give permission for their home hub to be used as a hotspot as well.
According to Virgin, it doesn't affect your connection. In its letter to customers, the company writes: 'Adding the Hub in your home to our wi-fi network won't affect the internet connection you pay for.
'To add your hub to our network, we'll switch on a separate connection to the hub in your home. This means the broadband you love and pay for will stay exclusively yours - and remain just as secure'.
If Virgin Media's claims are true, you shouldn't notice a drop in performance if other people are on wi-fi using your hub as a receiver. Virgin says it has limited the number of people that can use wi-fi on each hub to 'minimise disruption'.
The connection you use to go online with the Virgin Media hub is kept separate from the public connection. That means people using a hub that's not their own can't see what sites the owner is visiting or what content they're downloading.
If you're connecting to a public wi-fi hotspot yourself, we suggest using antivirus software as an added security measure. And always steer clear of entering sensitive information, such as banking details, over a shared connection.
If you don't want your Virgin Media hub acting as a hotspot, you'll need to get in touch with Virgin by visiting . From there, sign into your account and clickMy Profile. You should be able to opt out of the scheme under the Virgin Media WiFi Settings menu.
Even if you opt out, you'll still have access toother Virgin Media wi-fi hotspots.
Not really, no. Virgin's not the first provider to adopt this form of wi-fi 'sharing'. BT has a similar service, and it has been around for years.
Since 2009, newBT broadband customers have been automatically signed up to BT Fon. It means your BT hub acts as a wi-fi receiver for other BT broadband customers.
Fon was the world's first global wi-fi network, and for offering your hub you get access to millions of other wi-fi hotspots hosted by members.
We also spoke to BT and it told us that BT Fon has no impact at all on your broadband speeds, as wi-fi bandwidth is shared through a separate channel. Customers experiencing issues should contact BT directly.
