NB - I will need an idiots guide to this.
I have a new client who has a BT ADSL2+ installed with a Cisco 877 router. The router link is up and down like a yoyo - more down than up
I have come across this before with a draytek and it wsa due to the dsl modulation being set to auto as opposed to a specific adsl2+ modulation. That one needed to be set to ADSL2+ (Annex M) for example
if you can give me an idiots guide to this it would be really helpful. If you have any other ideas that would be great.
