Thanks for the post! I am sorry to learn about your issues with your broadband having a flashing green arrow. My apologies for any inconvenience caused.
I have tried to test things from here, however I was unable to locate any of your details via your forum account. In order to proceed with diagnostics, I would need some information from you.
I will send you a PM (purple envelope at the top) detailing what's required in order to proceed with diagnostics, please respond to me there and I'll get this sorted for you.
