Asus won't stay connected to wifi outside my home

[nontechmum]

My Asus is about a year old. It was fine for 6 months. I travel a lot and rely on it to re-book air tickets when things go awry (as they do with air travel) It now won't connect to wifi unless I'm practically on top of the router - fine in people's houses where I can see the router and move closer. No good at airports! Any ideas? Thanks

When at home download your WiFi drivers then use DDU to uninstall them and then reinstall the ones you downloaded
