Help please.

Hello, I need your help. I have a router(ASUS RT-NT12+) and I need internet connection in a room, but it goes through 2 brick walls, so the speed that the router gets(20Mbit/s) is in the room very unstable and it's usually something around

1-6Mbit/s. My question is, how can I improve the speeds over there? I was thinking that maybe a dualband router might help? or maybe one with more antennas? or faster internet connection?

Thanks for any tips, all of them are very appreciated.

Edit: I also have an extender in the room(ASUS RP-N12)
