Broadband just installed. How long until I have internet?

[#1]

Engineer came this morning and installed our broadband, we connected our router but the router has had no connection to the internet for the last 6 hours. (Orange light with flashing red broadband light).
How long until our broadband works?
Thanks for any help or suggestions!
