Hello, I work at an internet provider and we work only with TP-LINK, on ​​this EC230 model, it is sold as exclusive to providers, and on some routers the wan light is red, as if it did not detect the connection, I have already updated it , I changed un, cables, changed DCHP concession time, and only solved it by removing the DHCP server or changing the client's router, has anyone been through this?
