What is Wifi?

It's a way to connect to the internet wirelessly.

Things like computers, mobile phones, e-readers and games consoles have a network card built in that lets them connect to a wireless router using radio waves. The router is connected to the internet by a modem. So the internet connection comes through the modem, to the wireless router, to your device.

Is Wifi safe?

We take preventative measures to bolster security across our network such as running the latest security software patches, and proactively monitoring our service against risks. In addition to the security measures in place, we protect users through content filtering. From the moment our public wifi service was switched on in 2011, we've fully content-filtered our service at all venues. We were the first in the industry to do this. When using public wifi, we recommend that you always verify online certificates and only input personal details on secure websites. We also display a welcome page in each of our venues which identifies users by name, so you can be confident that you are connecting to a fully monitored and secure service.

My signal strength is low. What's going on?

Wifi can be up to ten times faster than 3G and GPRS. Also, most mobile contracts come with limits on how much internet you can use a month, usually between 500MB and 1GB. Considering the average iTunes track is about 7.5MB, it's easy to use that up - especially if you're watching videos online. Using O2 Wifi doesn't use up your mobile data allowance.
