I have a Dell 1526 with a wireless 1390 wlan adapter installed. I had to reinstall the windows that came with the computer. Now the WIFI light does not come on and the system does not recognize the wireless adapter. How do I get it to work again?

HP BLACK LISTS ALL NON HP WIFI CARDS(MODULES)
HP SOLD IT WITH 3 OR MORE WIFI CARDS HP FROM THEM ONLY
so wifi works at home (are you home) and wifi works on TV
other PC and cell phones, with wifi set to data?
if wifi is good then we focus on the relic nc6400 (2007 made)
the home network must have working set DNS selection too.
the 3 listed are
Choice of Broadcom 802.11b/g WLAN, Broadcom 802.11a/b/g WLAN, Intel PRO/Wireless 3945ABG 802.11 a/b/g WLAN
only those work
and only with HP drivers now gone. hp ended suport
googling them gets me endless virus infected driver, as a nice door prize(sarc off)
next time buy DELL and we can find 1000 of wifi card that work .
or cure #2
is remove the old wifi card from its slot.
then get USB wifi dongle. for w7 make sure it has support for old S7
they do work

just 1 fast search and there go. www.

Shut down all computers connected to the network, and reset the router. WAIT for the lights on it to return to normal. Start up one of the computer to make sure it has internet access. This will eliminate any issues the router may have.

Make sure you have the passphrase (password) for the network handy (If that matters.) You need to check to see that the computer using the adapter has the correct IP address, and that the adapter settings are getting the IP address automatically.

IF you still cannot connect, uninstall the adapter, reboot the computer using it, then reinstall it and try again. You may also have to go into the network and sharing center, advanced adapter settings, and remove the network, so it can be re-detected by windows.

Hi. You can download the driver from Dell website. I strongly recommend that even there will be more recent versions out there, stay with the versions released by Dell, Dell before releasing a driver tests it with the systems to ensure full compatibility and zero-problems with other devices:

Dell Wireless 1390 WLAN mini-card driver

Also for future needs, it's advisable that you go to the following web page:

Dell Drivers & Downloads

And enter the service tag of your Dell computer, so that you could get drivers specific to your system.

hope it helps

Hi Sivakumar133,

Some reasons why wifi stops working is due to corrupted driver or defective WLAN card. There are some ways on how to diagnose this problem, just reinstall the driver and configure it again with the wireless access point. You can download the WLAN driver for this particular system by visiting this link. You will notice that on the Networking Wireless LAN section it has 2 types of WLAN card, Broadcom and Intel. Just try to install the Broadcom driver because this is compatible with XP. If you're not sure what is the model of your WLAN just check it under device manager and look for Network adapter. After downloading, install the .exe file then restart the system. You can now configure again the computer to your router.

Hope it helps.

Thank you for using FixYa.

make sure the access point or router is on DHCP then connect the computer, but if its on dynamic IP... them enter an IP in range of what you have on your AP/Router

I am now on the same kind of computer and I used to have this problem- dell said it's a motherboard problem and they replaced it for free. Now it works just fine!

The 1390 WLAN Minicard may not be configured to communicate with your wireless router.
Check the wireless router settings, (check the wireless settings on your other computer) and configure the 1390 WLAN with the same settings eg. SSID, WEP/WAP encryption, etc.
Is MAC address filtering enabled on your wireless router, if so add the MAC address of the 1390 WLAN to the MAC address list in the wireless router.

Check the TCP/IP properties of the 1390 WLAN card the Internet protocol should not have a fixed IP address, set it to Obtain an IP address automatically including the DNS.

Use the Ipconfig command to see the IP configuration of the network cards.

Use the Ping command to see if you can communicate with wireless router.

Hi car7924,

First, make sure that the wireless switch on the left side of the computer is turned on (this should make the WIFI light go on -- beneath the lower right corner of the screen). If it doesn't work, then try going to Start Menu > Control Panel > Network and Internet Connections > Network Connections.

You should see the Wireless Network Adapter in the window that comes up. If you don't, you need to download the driver for that adapter. The most common adapter in the D820 is the Dell 1390 WLAN MiniCard, and the driver for it can be downloaded at the following web address:

http://drivers.softpedia.com/get/Other-DRIVERS-TOOLS/Others/Dell-Latitude-D530-Wireless-1390-WLAN-MiniCard-Driver-A17.shtml

If, on the other hand, you do see the Wireless Network Adapter, but it says "Disabled" underneath the name, then right-click it and select "Enable." This should make it work.

I hope this helps - please let me know if I can be of any further assistance.

Kind regards,
H2H
