My Wi-Fi router is provided by BT and works fine for my iPad and Mac mini. However, my MacBook Pro now won't connect to the router but will connect to the external BT hotspot.
When I try to log in it says invalid password. I've removed the router from the list via System Preferences → Network → Advanced but this has had no effect. I've tried adding
" before and after the password—now I don't know what to do.
