Hello! I have a problem with my Archer C80, it keeps cutting out randomly. 
 

it's running currently in AP mode. Cable comes from main router lan to blue port on the Archer. 

I have checked the cable with an network tester and it's good, also I checked the main router and it doesn't have any drops. 

Here's the ip config.

192.168.1.37 - Archer C80

255.255.255.0

192.168.1.1 - Gateway (main router) 

DHCP off

Smart connect ON 

And here is the error logs:

1 INFO 0days, 00:00:05, [lan]LAN: Set interface br-lan0 ip=192.168.0.254 netmask 255.255.255.0.

2 INFO 0days, 00:00:27, [httpd]Http server start!

3 INFO 0days, 00:00:29, [lan]ip is zero

4 INFO 0days, 00:00:29, [dhcps]Send OFFER with ip 192.168.0.100.

5 INFO 0days, 00:00:29, [dhcps]Send NAK to 0, lease ip c0a80064.

6 INFO 0days, 00:00:31, [lan]ip is zero

7 ERROR 0days, 00:00:31, [mcastproxy]Lan dev not find

8 INFO 0days, 00:00:33, [lan]renew mainLan--->eth0

I can't understand that much but I guess there is an ip conflict? I've tried assigning other ip and the problem persists. 
 

Any advice would be much appreciated, thank you!
