WIFI problem

I have this problem with my WiFi at home, first off where i have my router is a different room to where i have my devices, it is not possible to have them in same room.
The WiFi signal is very weak, i believe because all the door frames in this building are metal.
Now i have a repeater or WiFi amp called Wireless N, it used to work very well until i changed to fiber, now with a new router comes a new password and of course the repeater is set for the old password.
I have tried various methods to reconfigure, but i'm not a tech y and so far I'm stumped.
Any help offered is greatly appreciated.

Clarification Request
A few things.

1. Not a fan or user of repeaters. Too many failures, oddities for me.
2. Even so, I don't mind trying.
3. But without the full make, model, revision and such I can't check the manual as to what we need to do to set this up.

4. WORKAROUND? Set the SSID and password on the new router to same as the old router. May be easier than fixing the repeater?

Hi. I may be able to guide you through the process of changing your router's password and SSID. However, I need to know what the router's model and make is. These pieces of product information will give me an idea of which router you are now using. Also, I need to know what is the current Internet speed you have.
