[SmG XLORM]

So me and my mum (the only ones who use computers in the house) are getting really annoyed with when the power goes down and we lose our internet connection. We both have laptops so they are not affected but our router and modem is. I have found out that if I get a UPS I could keep my internet connection running as the connection itself doesn't require power only the router and modem do. To sum this up I am asking "what sort of UPS should I get?"
