'Connection Lost'

We are constantly receiving this message every time we try to post/edit a post in WordPress.

‘Connection lost. Saving has been disabled until you’re reconnected. We’re backing up this post in your browser, just in case.’

This makes it impossible to do anything within our Dashboard.

2 of us live in different continents so it cannot be our Internet providers suggested by WP techs last time we asked. And all is good with our host – no problems there. Please help.
