[NTLK] Can't connect my Newtons...

["Piotrowski Paweł (Newton)"]

I’m not sure about this, because I have manual IP (static, always the same) and MAC addresses are the same. So, nothing change in configuration. I had even MAC address assigned to IP address and I had this problem before… Still I didn’t discover details about it, but my conclusion is there is problem with WiFi <-> AP communication sometimes.



Best regards,
Pawel Piotrowski
