Strengthen wifi signal using android?

[Time Sheep 0]

Okay, Im writing this from my phone, so ill be quick.

My bro has a computer that stands far away from the router. Dragging cables between is imppssible. My phone lies somewhere in the middle when charging. Can I route the WiFi signal through my phone (Like an access point) to strengthen the WiFi signal to my brothers computer? It not, can I then do that on a Windows 7 laptop?

EDIT:

Fail forum LOL. Can somebody move it?
