Hello, the internet is a lot better on 5 ghz in my household, and the thing is, i can't connect to the 5 ghz from my bedroom. Is it possible to pull a cable from the original router and create an access point in my bedroom, and if yes, will it get slowed down? (i probably have to plug a 25 meter cable on the primary router)
