2 routers?

So i recently moved into a new apartment and i got a router but my internet is still slow(probably because theres like 10 device connected to it) i bought another router and i will have it connected to the first one then the second one will be in my room. Now my question is will there be any changes on my internet speed if i have ethernet connected from my second router to my computer.

You need to be clearer with what your intended setup is. What is the router going to be doing in the bedroom? Did you flash it or configure as a bridge to connect to the first, or does it somehow have its own separate internet connection? Otherwise you may just want to try swapping the new router in for the old to see if it gets you going faster.
