I have had this problem since I have had this camera -over a year and evenwith SW updates (i am running 2.5) i still have it!
Running on win 7, Verizon FIOS wireless router (actiontec) - i have another camera (#1) and it is a trendnet TV-IP 501 and it works flawlessly. This one is cam#2, static ip address, 192.168.1.15, port forwarding enabled, etc...
Here is the issue:
It works intermittently - and I ALWAYS get the error:
Cannot find AUDIO data. (first it says MPEG, then JPEG, then FINALLY Audio) Your network camera may not be supported. - then a few seconds later it works... for a while -the error stays there, but it works... sometimes hours, sometimes minutes, then will show as NETWORK CAMERA OFFLINE - then magically, it will come back on at some point later- If i restart (stop/start) the camera in iCamsource, it usually fixes the problem. I have reset the camera, uninstalled and reinstalled SW and the camera data multiple times and then on occasion i wont get the error and it will appear to work... for a while. Sometimes a day, sometimes an hour - then back to the issue above.
I'm pretty technical, and I have tried everything I could think of, checked the forums repeatedly, now coming here myself to see if anyone can help.... THANKS.
