My laptop can´t reach router in another room so i was thinking about buying a wireless router to put it in my room. So, my question is would that work? Can a wireless router reach signal from wired router in the same house? If not, what should I buy instead?

Other answer:

A wireless router, trying to link to another router, will see the same weak signal your laptop sees, no different.
Your choices are:
1) Run a wire from router to your room, and add a network switch and/or a wireless access point (WAP). A second router will also act as a WAP, with certain limitations (but you can still surf the web, etc.)
2) Run something like a powerline Ethernet adapter. These come in pairs, one at the router, one in your room, that plug into the power outlets (never via a power bar – must be direct into wall outlet). There can be issues if your room and router are on opposite sides of the powerline split phase, so keep the boxes in case it does not work and you need to return them.
3) Run a wireless bridge (special router with bridging mode), but with an external higher gain antenna in your room. The high gain antenna may help give a stronger signal.
4) Buy a USB wireless adapter that has a detachable antenna, or one with a high gain antenna. With a high gain antenna on your laptop adapter, you will get a better signal. Look for 10dBi gain or more. Do not believe a lot of the Chinese knock-offs that claim high gain with a simple whip antenna…. However, your laptop becomes less portable with a large antenna attached to it.
Apparently you feel that somehow one wireless router (wireless access point actually) will be able to pick up and amplify the wireless signal of an out of range wireless access point. It won't happen. Buy a wireless access point, connect it back to an network switch port of the existing router via CAT6 cable. Configure the wireless access point w a static IP address not in the DHCP pool of the original wireless router; allow the original wireless router assign DHCP on the new Wireless Access Point; use the same SSID, Preshare Key, Encryption, etc as with the original wireless configuration and you will be in business; in fact you can travel from one to the other wireless access point without dropping signal IF you place them to where there is some signal overlap which is pretty easy to do in a house.
V. Perkins:
A "wireless" or Wi-Fi router is a WIRED router that has Wi-Fi or wireless functionality. The "wireless" word refers to the router's ability to allow devices to connect to it wirelessly. It does not mean the router doesn't need an input "wire."
