Try adding the Debug window to your EZB program and capture the error messages and post them here.

@Will2829, If able assign a static IP address in your router for your EZB. How old is your network router? Others here including myself had to buy a newer router. Have a read through this thread I started when I was struggling with this issue. My setup is running like a clock now:

Connecting To Two V4 Ezb's

You might need a better router.... I had the same problem (constant disconnects). I solved it by upgrading my router........

Router is pretty new (< 1yr)...Netgear high end

Another piece of information that might be useful is that I can connect via my web browser at the 192.168.1.15 IP address just fine and do diagnostics (activate sounds remotely).

Hi @Will2829,

What do you have running within your ARC project when you try to connect?

Disconnect and no connect issues:

On top of checking your router, you will want to look into your anti-virus software also. I have discovered that AVAST hates ARC.

Avast will:

1. Block the download of the ARC EXE
2. Block .dll's when trying to run ARC, even when adding the entire folder of ARC to the exclusion list.
3. Prevent the connection of ARC to an EZB V4 (EZB V3 no problems).

This has been confirmed on 2 Windows 7 64bit computers and 1 Windows 8 computer.

AVG Anti-virus has no issues with ARC
