Network problem with Archer C5 AC1200 v1.20

Installing and Using OpenWrt
1

Hello all!

I am having a kind of annoying problem with my network. Like every 8 hours, I lost internet connection and I don't know why. This happens but the network connection is still up and my computer is still connected to the router but with no internet access. I can solve this by simply rebooting the router, but is kind of annoying me having to do so every time.

My configuration is

Internet <---> ISP Modem ZyXEL AMG1001-T10A <---> Archer C5 AC1200 v1.20 router <---> Clients

I have no access to the ISP modem and no way to ask for configuration to the ISP. Are there any hints on what could be happening? How can I troubleshoot this problem? Any suggestion would be appreciated.

Best regards.

Here is the Firmware version and Kernel version.

Firmware Version: OpenWrt 19.07.7 r11306-c4a6851c72 / LuCI openwrt-19.07 branch git-21.044.30835-34e0d65

Do you know why it seems to be crashing?
