Network doesn't work after some time on ZyXEL P-2812HNU-F1

Installing and Using OpenWrt Network and Wireless Configuration
1

About two weeks ago I;ve bought ZyXEL P-2812HNU-F1 router with installed LEDE Reboot 17.01.4. I configured it and everything worked fine, but after some time wifi stopped working. I was connected to wifi network, but couldn't connect to my local devices(even router) or wan servers. I've got computer connected with cable to this router, and sometimes it works when wifi not, and sometimes it also doesn't work. So I have to restart this router every morning. Sometimes after this restart network doesn't work after 10-30 minutes and I have to restart again. After this everything works fine until next morning. I also remember, that once network get down while I was using it at night. Do you have any idea why this is happening? How can I prevent this?

SSH in to the router and run the following...

cat /etc/config/network

cat /etc/config/wireless

Note: Make sure to obscure the "option key" value(s) in the wireless config results before posting.

I configured one lan port as wan, because my wan port doesn't work. I think I've done it with this blog post https://onetransistor.blogspot.com/2017/04/wan-port-openwrt-lede-vlan.html

I suffered from a similar issue and wrote about it another thread: [Solved] Wireless interruption on Zyxel P2812HNU-F1. I ended up resolving my issue by installing a separate USB wireless adapter. Cross-check against my findings (especially the kernel logs that I get when the problem occurs) and determine if you are looking at the same problem.
