Sure, i'm glad to help you
In this case, it might be an issue of the WLAN (wireless Ethernet connection between your mac/router/netstream 4Sat). I have few suggestions for you here:
1. use network diagnosis of our eyetv reporter tool to check if your network configuration is fine;
2. check if eyetv 3 and eyeconnect (a part of eyetv 3 software) are allowed under firewall settings.
2*. Another way to check if eyeconnect is allowed:
find eyeconnect under Mac - Application - right click and choose show package content - resources - eyeconnect. Now double-click eyeconnect, if it asks "would you allow eyeconnect", please choose "yes", if nothing happens, everything is fine.
3. use cable connection between your mac and router
4. check security settings of your router (mostly using 192.168.0.1 or 192.168.0.0 to access your router)
We also have several old netstream 4Sat in our office and they are running almost 7x24h. So a bug of software could be excluded. May you give me your receipt via PM? Our team will discuss about your issue soon and try our best to do what we can.
Apologize for your inconvenience again...
