[SOLVED] How should I upgrade my router?

[jtayped]

I have a Livebox Fibra router from Orange and my ISP comes with fiber optics, so I don't know what router I should buy because of the SC fiber optics cable. I don't know if there is any adapters or anything like that.

What do you mean not enough bandwidth. Almost all routers can provide gigabit speeds via ethernet connections. If you have issue with the wifi just buy any router that you feel has better wifi and use it as a AP. Generally the problems with wifi many times are the end device and not the router.
