i just can't find my ip cam on the network....?

It is unlikely to be a port issue..

Cheap IP cams are more trouble than they are worth really.

Please read the full instructions that came with the CAM..

Figure out how to set it to default settings.. and do it.

Does it have a default IP address.. if so plug it directly into the PC.. forget using the TC.. set the PC to the same IP range as the cam.. and then run the setup software.

Once you have actually got through the setup then plug it into the TC.. if the PC also cannot get access to the CAM when directly connected.. throw it in the bin and buy something that is a bit better quality.

Is the IP Cam set for DHCP? If you don't know please read the instructions that come with it.. some will come with a static address and will not work until you fix it.

To find the camera on the network, either open the network utility in the Mac and do a netstat scan.. it will show all the available devices.. or using v5 airport utility it will also show all computers connected to the TC.

Just test each one then in the browser.. all IP cams have html open..

Reading the instructions is really key to this.. as the camera should have a name you can use in the browser.

becourse i can find the ip and mac adress from the cam on my Dell Laptop running on Windows vista

Is this setup as you described.. the camera plugged into the TC? Both Mac and PC plugged or on wireless from the TC?

What exactly is the IP of the camera?

What is the IP of the TC?

When you say you cannot find the CAM on the TC what exactly are you expecting?? Nothing at all will show up from the CAM on the TC when you have it plugged in by ethernet.

How do you open the IP camera to access its controls.. on the PC or does it use a special PC only software??is it just via a browser?

Have you tried opening it via browswer in the Mac?? if the layout is as you described and you can open it from the PC then the Mac will work exactly the same.. but cheap CAMs will not have Mac software. So this will only work from a browser.

butt on the Dell laptop i cant install airport tool? or can i ?

Of course you can install the windows version of the airport utility.. how does this help you.. I think you do not understand that the TC is a dumb hard disk in a router.. it offers nothing for your network.. it will never be able to see the Camera.. it is not smart enough to do anything but save files from a computer.

if you want something more user friendly, download the fing app from your ipad or iphone, will show you both wired and wireless connections on your net

factory reset your camera, connect it via ethernet to your router and open the fing app after 1-2 minutes

if you still don't see it, post a screenshot of the fing app
