I have 4G LTE wifi router (Huawei b310s-925)[Router A] has only one LAN port. and another router Prolink H5004NK, that I want to cnnect to router A, lan to lan(connected both routers using LAN ports on both devices), and use the internet on both routers and increase the wifi coverage, I tried turning off DHCP on second router, but first router LAN doesn't have DHCP settings. and turning off DHCP on second router can't connect to PC. I would like to know if there is anything else I have to change to get this right.
