Hello,

Thank you for posting your question in fixya.com.

You can find the wifi driver for compaq by visiting this website . Click on Drivers and Updates and look for your computer. Enter the correct operating system and install the driver for wifi.

If you want to make sure all your computer's driver is updated, you can install an automatic updater like RadarSync to your computer. It should work.

I hope this helps!

If you have any questions, please drop me a line.

Checking the HP/Compaq site, the Compaq SG3340IL uses Realtek Gigabit LAN.
You can download the needed driver HERE.

Hi gem,

Which operating system are you using? What drivers are you missing when you get into "Device Manager" (assuming you're using some version of Windows?

Above is the link to Compaq... you have to select your specific model of CQ42 (look for the sticker under your laptop), choose your operating system and download the relevant ones.

I often install drivers with the motherboard first (most likely an Intel chipset), then all the rest such as graphics card (video drivers), audio, networking, wireless, modems, card readers, etc.

Hope this helps!

i think wifi drivers are not installed
install and check
good luck

Hello,

you can download your wifi driver from the below link:

http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?prodNameId=3559276&taskId=135&lang=en&cc=&prodSeriesId=3466274&prodTypeId=321957&refresh=true

Once the link is opened, select your operating system and proceed for the download.

You also have the opportunity to download other drivers because this link has A-Z of your drivers.

Good luck.

You must get in touch with HP and check you are using the correct driver or the latest version. If not then perhaps there is an issue with the driver file and you can download it again.
