If your router broadband line light is flashing amber does this mean the line is not yet ready for broadband?

You need to check what the 'broadband light' means. If it means synchronisation then it means that the ADSL (asuming its adsl) signal is not getting to the router. This could be that its not live yet, theres a problem with the line, theres a problem with the filter or wiring etc. If the 'broadband light' is the connection / ppp light then it could be that the username or password are incorrect. I would advise calling your ISP's tech support or having a look in the manual. I use www.odyssey-systems.co.uk for my ADSL and they sent one of their engineers out the same day.
