I reinstalled xp hom on my inspiron 1525 cannot find the network adapter anywhere in the device manager dont know what it is can you help me

There is a reason the wireless network adapter can't be accessed. It could be that you've turned off your wireless network. The driver for the adapter could be corrupt.
Check to see if it's turned on. If you access your network adapters, you should see if it is turned on or not.
If this doesn't help, from the device manager, remove the network adapter. Restart the computer and it will find the adapter and reinstall it. I think this will solve the problem.

With assumption you're already make the wireless enable in BIOS setting. In the device manager you should see what the type of wireless wlan card you used and make sure it's already turned on via your switch on your laptop. If it was, then you need to find out the right wireless device driver for Dell Inspiron 1525. Here's the following:

1. Visit Dell Support site and open the Network tab in the table.
2. Find your wireless device and download the driver for it.
3. Aim to a folder on your computer or any external drive if you have it.

At the Inspiron 1525 laptop

4. Click Device Manager and Network Adapter .Here you should see a WLAN Mini-Card or might you only see "Unknown Device".
5. Right Click on it and go to properties to select the Update Driver. Now you should browse the folder to select the driver you're already download at the first step.

Just follow the instruction appears completely. After installation the wireless wlan driver at Dell Inspiron 1525 finish, then reboot the machine and know your wireless connection should be works properly.

When you reinstalled Windows, Windows probably did not include a driver for your wireless adapter. A driver tells Windows how to interface with a certain device, such as a wireless adapter. You can easily download the driver online and install it. Once installed, restart the computer and you should again have the ability to connect to wireless networks.
I've gone to the Dell website for you and found the correct driver. Please visit this link: http://support.dell.com/support/downloads/driverslist.aspx?os=WLH&catid=5&dateid=-1&impid=-1&osl=EN&typeid=-1&formatid=-1&servicetag=&SystemID=INS_PNT_PM_1525&hidos=WLH&hidlang=en&TabIndex=&scanSupported=False&scanConsent=False
On that website, I would first try downloading the first driver on the list. If that doesn't enable your wireless after a reboot, try the other ones. After the correct driver is installed, your wireless will be working again.

Here is the official link for all the drivers for your laptop. I suggest you to choose your operating system and download the drivers you are looking for. In case of trying to install a driver for wrong hardware the installation will not proceed.

In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.

After the installation of your operating system make sure that the driver of your wireless adapter is also installed. Also you need to check if the wireless switch of your laptop is turned on. If you dont have the driver of your adapter you can download it ath dell support website
