I've tried to access my MacBook (ancient) this morning and it won't connect to the internet.
The battery went ages ago and will only work now when plugged into the wall.
Today, it won't connect to the internet and the time and date have reset and I can't change then in system preferences as it is greyed out.
Any ideas? I've tried re-starting, doesn't help. It isn't my broadband as I've tried creating a hotspot from my phone and it doesn't like that either.
Really bad time for hardware problems as I am job hunting!
