The operation of a separate modem was not familiar to me. So first read the instructions in detail. Although on the package and also here is on Amazon: "No configuration necessary," I noticed the same first the large piece of paper with the instructions for configuring the eye. So same time the supplied LAN cable is connected to PC and as described in the browser to connect to the modem with [...] make attempts - nil. Now the whole discussion whether static or dynamic DHCP allocation and adjusted everything possible on the PC and twisted, even to despair followed by System Restore :-(
On the download page of D-Link (only the next day from the office reached because my Fritz box was broken so) I found an indication that the 321B modem is already configured as a bridge and you have to do anything more if you have a router with PPPoE or so used. So - in short - just no configuration needed - Thank you D-Link.
Why can not you please so enclosed exactly as the list ???
So, technically sound, small, convenient, inconspicuous, and provided with a small off - I like that. Actually, 5 star, but because of unötigen deception and bad instructions only 4 stars from me. (This Note that this modem is preconfigured for use with router there are really only on the support page of D-Link, not in the enclosed instructions, and also not on the enclosed CD)
