Pick the route before you write anything
Post a thread here when you want to know what is happening and why, or when you suspect the fault is on your side of the router. Write to support when something has to change at source: a MAC re-bind, reissued credentials, a line that authenticates nowhere. The two are not interchangeable, and a source-side request posted as a thread simply waits. If you cannot tell which you need, describe the symptom in a thread and somebody will route you within a reply or two.
