Macbook air will not work on wifi
Hi
I'm overseas with work for 3months and I'm staying in a serviced apartment with wi-fi provided for the building.
My Macbook Air will not work on the wi-fi. On Chrome I get the following message 'ERR_CONNECTION_REFUSED' , Firefox is 'Server not found' and Safari just doesn't load. It sometimes eventually loads but does not download the website properly.
My iPhone and work laptop (a lenovo) work fine on the wi-fi and my mac works fine when I hotspot off my phone.
I don't have access to the modem to reset it or anything.
Does anyone know how to fix this? I've spent hours reading through forums trying to fix it but nothing will work!
Thanks
MacBook Air, OS X El Capitan (10.11.2)
