Summary: A major warning should be included with this item, as noted in the review by DC the version shipped on the router has a very serious security flaw. A firmware patch is available but is not downloadable from the Dlink website.
Summary: wasted a full day on this one. I got it on line, altered the settings to bridge mode etc connected up my asus ac 1750 NOTHING absolutely nothing no net connection. spent the rest of the day struggling, and I do know a bit. Both got returned.
Summary: Great little unit. Excellent description on dlink site to set it into bridge mode. (http://www.dlink.com/uk/en/support/faq/modems/dsl-modems/dsl_320b/how-to-setup-dsl-320b-revision-z1-in-bridge-mode). It's now hooked up to a linksys wrt54g2v1 using dd-wrt. Working perfectly!
Summary: It "just works" but...BIG WARNING. As supplied, v1.05 of the firmware has a security defect. If you use this as a modem or modem/router to connect to your ISP (therefore you enter your username and password, encapsulation, PPPoA, DNS settings etc then it can and will be hacked.
