Hi ,

Open a terminal [Ctrl]+[Alt]+[t] and give this command

iwconfig

You will see various informations , Signal included.

Also you can check the signal from Network manager Icon (up bar , right corner), but is a graph measurement.

Thanks

While in the terminal, type:
sudo iwlist scan
<your password>
to see the signal strengths and channels of ALL access points visible to your machine.
This allows you to pick another channel if you see other powerful signals on the channel you use.
