Here is some advice from a reputable Tooway service reseller (Europe Satellite) who helps their customers:
"Check that Skylogic have your modem MAC address in the Skylogic Tooway hub database"

This requires that your reseller communicates this information to Skylogic. The MAC address is something like 00:12:af:00:b3:34 and probably marked on a label on your Surfbeam modem.

A search of Google for skydsl throws up this page, which, if true, is rather discouraging:

It is the job of your service reseller to help you with your self installation with advice and assistance. Call them and tell them your MAC address and ask for help. The MAC address comprises hex characters, i.e. numbers 0 to 9 and letters a to f. Make certain it is communicated correctly. Use a magnifying glass to read the label if necessary.

Please provide feedback here in due course - whatever the outcome. Good news particularly welcome !  Thanks.

Best regards, Eric.
