Hi,
Go to the link Driver and download Networking:
Wireless LAN driver .

Thanks for using FixYa.

Driver for Windows 7 (32-bit and 64-Bit) are available.
As the laptop comes with 64-Bit version, these drivers are available at Dell Official Site.
Dell Inspiron WLAN (Wifi) Driver for Windows 7 32Bit are not available from Dell Official or Microsoft Update (online).
I came accross this issue and solved it by searching 32Bit Drivers for the WLAN hardware and found the drivers. Below is the link from Intel Official Support.
Intel WiFi Link 1000BGN Drivers
Download/ Install the drivers/ and Enjoy wireless internet connectivity!
From adaptor properties - Advanced, select AUTO for 802.11n Channel Width to experience 300Mbps downlink Data Rate.!!!

Hope it helps! Good Luck!

Did you try Intel Download Center

Hi, I take it that you have upgradred from XP. This will cause problems as your machine is designed for XP. The best solution is to go to the dell site and download the latest driver, even if its the one for XP.
Try this link: http://support.dell.com/

Well it looks like HP left the Compaq user SOL. So looking at what they usally put in them its either an Intel or Broadcom WIFI adapater. So go to Intels support download site and download the autoscan tool. It will see its own hardware and show u a link to get the driver. If its the Broadcom driver look up Broadcom drivers on HP's website try them out 1 by 1 from models about your year of make. Here is a link I found for that laptops drivers. I waited the 20 seconds and it did produce a RAR folder to download the driver for the WIFI. Download at your own risk but it looks bug free.

Reset the router back to factory defaults by using the end of paperclip to push a very small button on the back of it. You will have to reset the security if desired.

hi
You will need to find the model of the wi fi card, once you have that, go there website and download the drivers. Its normally intel, but check first.

the Compaq website is showing two possible wifi drivers..

If you go to the link above and go down to network and then choose either Intel Pro/Wireless drivers or Broadcom Wireless LAN driver. (I would probably try the Intel driver first).

Download them to your desktop and then double-click on them and follow the install instructions. If the first one doesn't work go back and try the other.
