Laptop is not receiving wifi signal
Laptop no longer receiving the wifi signal.
Can only access the Internet when plugged in with cable.
Check that your wireless adapter is working properly.
Go to Start > Control Panel > Device Manager > Network Adapters, expand tree, find your wireless adapter.
Is there a red cross or a yellow exclamation mark beside your wireless adapter?
If yes - red cross - right click on wireless adapter, click on properties. New box will open, middle of box is Device status box. If it states device has been disabled, enable device (click cancel, then right click on wireless adapter, click on enable).
Check that your Wifi is now working.
If yes - yellow exclamation mark, go to the HP website and download the latest wireless adapter drivers for your model laptop and OS. Update the drivers then see if your WiFI is working.
If no, and wireless adapter status states that it is working properly and you still cannot see any networks to connect to, here is a link relating how to troubleshoot wireless problems in your laptop.
I know it may sound stupid but if your laptop has the WiFi Antenna icon button next to the Power button, is it lit up? If not try pressing it as your WiFi Antenna might be turned off/disabled.
If you look at the lower right hand corner of the taskbar where the date/time would be, do you see your Wireless Signal? If so, does it have a Yellow triangle with and exclamation point in it or a Red X?
