4540 of proBook Wireless Driver not work... Unidentified network

I just bought 4540 s ProBook (I7-3632QM)
Product number: H5L54ES #ABV

I installed windows 7 ultimate, with the help of this forum, I have installed all drivers, between the wireless network was working and I could browse the internet

but after I have installed all the required drivers and Device Manager seemed well my dose of wireless network not working and says:

Connected to the unidentfied number of internet Network Access and can not see my wireless network

I tried the network (Wifi/Bluetooth) button, changing whilt light to yellow light mode and both modes work still do not

can someone help truble shoot this question

This can help others:

I managed to solve the problem by installing HP Connection Manager, WIFI showed tuned out... I clicked the power button and Wifi again active.

I really don't know what's happening at the back of this...

I failed turn on WIFI directly from windows, which should not be the case... I solved my problem, but I'm interested to know how to control it without the HP connection manager.

Thank you
