Hi everyone,
I have DVR (AVTECH AV791) installed 2 years ago. So far no problem with LAN access and external remote access (via dnydns).
Recent 2 months, I found that LAN connection problem. I can't access video viewer (software of AVTECH) via PC. Error message is connection error.
I have done the followings:
1. DVR internal IP is 192.168.0.110. While ping this IP, no problem. Lost = 0 (0% loss)
2. I have upgragde latest firmware for both DVR and video viewer. Info as below:
DVR firmware: 1205-1042-1016-1030
video viewer firmware: 0.1.9.7
3. I re-boot the DVR, connection is back. But just fine for 2 days. After that, need to re-boot again.
How to troubleshoot the problem? Please help.
Thank you so much
