EI have 2 wi fi routers, how can I install them both if I have 1 dsl account? I tried splitters but it doesn't work.
Why do you have 2 routers? If you need to continue the signal, you need one router and a signal repeater, not another router.
Turn off DHCP and NAT in the second router and use it as an access point. Then, connect the two routers using LAN ports. Plug the WAN port of the 1st router into your DSL modem, and then plug one of its LAN ports into the WAN port of the 2nd router.
