Realised at the last minute I couldn't connect my laptop to the modem because who even does that anymore? But in this instance, WIFI was not an option (long story) so found this, bought it, clicked and collected and whammo, problem solved and I'm a very happy camper. In the past I've tried buying other no-brand alternative adaptors etc to save a few bucks and it almost always ends badly. These days I stick with the real deal.
