Have ordered due to constant line terminations on the advice of a technician, a new MDSL modem. I chose because of the good reviews on the Allnet ALL0333CJ. It was delivered quickly, packaging, etc. in order. The package includes everything you need to use. After I connected the modem, I must unfortunately conclude that now no longer connect to the Internet took place. After I checked all the settings on the router, I have tried to produce directly from a PC without detours a PPPoE connection. Also unsuccessful.
I then sat down with the manufacturer, and with my provider (Net Cologne) in conjunction. Result, the modem can not be used at the provider Net Cologne since parameter (VCI & VPI - you can not change yourself) do not match.
So wrapped up the modem again and sent back. Restitution proceeded without problems.
