I recently got my 3640 setup on my bussiness ADSL line which is provided by BT (british telecom).
When we used to have the BT bussiness hub we had a downstream of 5.5 or 6 mbps.
Now on the 3640 we have 2.3mbps and was wondering if there is something i can do to get this back up to where it should be. If we use BT equipment it goes stright back to 5.5 so this is confusing me slightly.
I have attached the config i currently have.
