Many laptops require drivers then to turn on the adapter the makers have an APPLICATION to connect the WiFi on/off button to enable/disable the WiFi.
This is why so few can clean install Windows today. They hop in the drivers seat and take off. Video follows.

PS. Easy to fix. Use the restore media.
The hard drive in my laptop crashed so I have replaced it with a new hard drive and re loaded windows 7 32 bit, It says there is no network connections available and when you trouble shoot it says there is no network controller driver and no pci communications controller. I tried downloading and installing a network control driver but it then came up with an error that said there is no intel (R) adapter on the computer. It is a Toshiba satellite L500 part/model number PSLS9A-01U012. Do you have any idea what I can do to rectify my problems.
