Question

how can i know whether i could get a good signal strength etc..?

Answer 1

Depending on where the access point it, that will determine your signal strength.

Say you installed a router to a computer in your house, and you are using a wireless USB connector within a different room in your house, or if already installed on a laptop or something as such, you'd have excellent signal strength because you're in your house. The farther you are away from the access point, they lesser your signal strength will get.
