This camera does IPv6. just to be clear about all of this, i know *squat* about setting up one of these things, having never done it before, so let me describe what i think is the end result, and people can point out where i am going horribly wrong. given that this camera supports wi-fi, i had imagined that the end result would be that it would eventually be configured as just another device on my in-house network, having been assigned an IP address either dynamically or statically, at which point i imagined i could fire up either a browser, or some webcam app like "cheese", point at that IP address, and view the live video stream from my linux laptop (or from a windows or mac machine with the proper software as well). make sense so far? now, this particular camera has no wired ethernet port (not surprising), so it can't be connected to the in-house router for initial configuration. it does come with an initial SSID and password, so i assume that, to configure, one normally downloads d-link's configuration app (https://www.mydlink.com/apps) and connects to the camera's wi-fi network for that initial configuration, but there is no obvious linux client to do that. therefore, i'm assuming that one *needs* some mobile device (iPhone, android) for that initial configuration. am i understanding this properly? in short, at least for this camera, i absolutely require an android or iphone with the d-link app for the initial configuration, which is kind of a pain, unless i have this completely wrong. am i at least understanding all this correctly? rday -- Robert P.

Can you just connect to it using wifi to that SSID and password as if it were an AP and if you really need your laptop connected to the internet at the same time, use wired ethernet. Then use a browser to configure it? Notice that hand-wave there in the last step? Maybe it acts like those annoying hotspots with security layer violations and then once you try *any* DNS lookup with your browser, your web session gets redirected to the cam network configuration page? > in short, at least for this camera, i absolutely require an android > or iphone with the d-link app for the initial configuration, which is > kind of a pain, unless i have this completely wrong. This would surprise me and I'd take it back if that were the case, but it is possible that there is no other way to configure it. > am i at least understanding all this correctly? o_O > rday slainte mhath, RGB -- Richard Guy Briggs -- ~\-- ~\ -- \___ o \@ @Ride yer bike!

It is harder to expose a new device to a trusted open wifi network than to a trusted wired network for initial bootstrapping. So, there's a bit of a chicken and egg problem here. Most wifi networks require authentication now (or should!). If your camera doesn't have a wired ethernet port that you can connect to a trusted network to do the initial configuration, how do you do that bootstrapping? It looks like they've turned it around so that you authenticate to it first so it is acting as a server for you to connect to it, then configure it to switch from AP mode to managed mode whereupon it can now connect to your secured wifi network with credentials you provide. Does that make sense and answer your question, or have I completely misunderstood the problem? > sorry. No need to be sorry!

Power is confirmed when the Status LED is lit. Step 2: Press and hold the WPS button on the camera for five seconds. The Status LED will start to blink green. Then, press the WPS button on your router within two minutes. Your router will automatically assign your network settings to your camera. Step 3: From any computer, open a web browser, go to http://www.mydlink.com and log into your account. Once mydlink detects your camera, a New Device Found! notice will appear in the bottom right corner. Click on the camera from the New Devices list and then click Yes to add your camera. Your setup is complete. however, the user manual is adamant that this only works with a registered d-link cloud router and an active "mydlink" account, so it doesn't really solve the problem. one suspects i should restrict my search to cameras that have an ethernet port for initial configuration. rday -- Robert P.
