Hello, I was running Windows 7 and I replaced it with Windows 8. Something happening and anyway I ended up losing Windows 8 so I installed Ubuntu. When I had Windows 7 it was already installed so there is no disk and drivers etc. already installed.

I installed a different copy of WIndows 7, Home Premium. I cannot use my Laptop's Built-in wifi now. I downloaded the driver for it, installed it. The icon in the tray is the Ethernet showing that it is not connected, the wifi is not shown in the Network Connections either.

I am using Toshiba Satellite P750 and the PC Diagnose Tool Reports that network is:

Realtek PCIe GBE Family Controller version=7.38.113.2011

I downloaded the driver which is:

Realtek Wireless LAN Driver 2.00.0013.L_110110

Have I done anything wrong? Does anyone have a solution for this, thanks.

do you have to enter your broadband details ?

no user or pass required, I just need to enter a key. No wireless networks are shown in the list of available networks it can't even find there is a wireless card in the laptop. It worked on Windows 7 originally, and on Windows 8 and on Ubuntu and on this install of Windows 7 it now does not work.

I am stumped with this one.

Try a fresh reinstall probably a problem with your install disk.

Install your wireless drivers if needed.

What I would do is;

Disable the network/wireless adapter thing from Device Manager and then re-enable it

If still no result,

Uninstall the driver, reboot, and then reinstall it

This is a fresh install but has no drivers for my laptop.

I have done all of this, I reinstalled the driver after I downloaded it too.

I have fixed my problem. This is how I fixed it:

In device manager under "Other Devices" a device is shown as Network Controller and says it has no driver for it. Open it up and went to Details and got the vendor and dev numbers from it (PCI\VEN_168C&DEV_002B) and googled it, turns out I was installed the wrong driver. I needed the Atheros WLAN driver so I downloaded and installed and now my wifi card works fine.
