Enable wireless on Hp probook 6550b - HEWLETT-PACKARD HP ProBook 6550b Notebook

Hi there,
You can enable your wireless lan via quick launch button on the strip , when tapped it will show you blue light when disabled it will show you with orange light, if you see that light is still blue but you are unable to find any wireless network in network and sharing center
simply open network and sharing center > go to change adapter settings right click on wireless network connection and select enable ,
now your wireless should work,
Feel free to contact us if you require more assistance,
Regards, Bilal

The possibilities (in order of most likely):
1. There is a wireless button or on off switch somewhere on your
laptop. For HP, it's usually a button dead center above the keyboard
area, with a bright blue LED that's lit when the wireless is enabled.
Sometimes, it's a slide switch on the front left of the laptop. It's
there, somewhere.
2. Windows will allow you to enable or disable the wireless device.
Go unto:
Control Panel -> Network
Find the wireless device. *RIGHT* click and see if it says "enable"
or "disable" at the top of the list.
3 Many laptops come with "wireless managers" that take over running
the wireless and sometimes the ethernet devices. I have no clue what
comes with your unspecified model HP that might be a laptop. However,
if you do happen to have something other than Windoze Wireless Zero
Config running the wireless, check its settings for enable/disable.
4. The BIOS sometimes has a wireless enable or disable setting.
