probably you did not install driver for them ..
Drivers are here :
HP Mini 110-3000 PC series*-* Download drivers and software - specify product name - HP Business Support Center
choose your laptop then your system ...
If your hardware drivers are all installed and the problem persist then it may be :
1- very weak signal !
2- SSID is hidden (router settings)
3- wireless switch is OFF (in your laptop)
4- bad laptop ! ( impossible but if every thing else failed it is a reason !)
hope this help
