I'm using a Linkys wireless modem, however, I don't get good wireless reception due to solid concrete structure that is abundant in my house. In the room, where the router is, I get good reception, however, speeds are so disappointing in the next room. I do not any reception in the upstairs.

There are dropping out, random restarts that vex me and I am considering to buy a new router that can ensure better wireless reception. Should I use amplifiers or signal boosters to improve my Wi-fi?

Thanks,
