My latop couldn't detect my own wireless.

Hello,

I have my Laptop Compaq V3700, I could not detect my own wireless. I have been trying to detect a home or office, I could not find both of them. However, the weird thing is this Laptop could find and connect to other wirelesses nearby. I am not sure does the distance matter coz it can detect others by not my own wireless. Plase help

In additonal to my question, I als try to use anot laptop or my phone. Those devices can detec my home andmy office wireless withou any problem. That'a why I am sure it gotta be something wrong with the Compaq laptop.
