network controller driver will not install on pavilion dv7-6c20us

[LouSwatch]

After a fresh install of Windows 7 64 bit, I've been going through and installing all of the drivers.  I can't seem to get the WiFi to work, it says the driver "may not have installed correctly."  The wired LAN controller and all other drivers seem to install just fine, but not the wireless ones.  (I've tried a few)

I also went into the BIOS (as I read on here to try) to disable the LAN power saving, but that option was not there for me.

Hi:

Please click on the network controller in the device manager. Then click on the Details tab.

In the Properties drop down list, select the second item (Hardware ID's).

Post the top string of characters you see.

Those will ID the model WLAN card you have and we can go from there.

OK I got it working.  I actually found real advice on Yahoo Answers (I know, right?)

The driver that ended up working was here:  support1.toshiba-tro.de/tools/updates/realtek-wlan/realtek_wlan_win7_2000016L_20110523.zip

These were the instructions I followed:


First you must know what model of network card you have in your system.
If you are using motherboard's network card then you must install the drivers from your motherboard CD.

If the network card is a PCI card, then you must:

1. Right click on MY COMPUTER then click MANAGE
2. Go to Device Manager and right click on "Network Controller" (should appear with a yellow question mark) then click Properties.
3. Go to "Details Tab" and you should see "Device Instance Id" and below you should have something like that:

PCI\VEN_10EC&DEV_8168&SUBSYS .......

The parts that interest you are the codes after "VEN_" and "DEV_".

In my case, the codes are 10EC and 8168.
Go to www.pcidatabase.com and search for first code (VENdor code).
Then click on Vendor Name and search (CTRL+F) for the DEVice code.
There you should find the model name and number of your network card. You can search then for drivers.

E.G.: Search for VENDOR 10EC and you should find:

Realtek Semiconductor

Click on vendor name, and in the page that appears search for 8168 and you should find:

Chip Number: RTL8168/8111
Chip Description: Gigabit Ethernet NIC(NDIS 6.0)
Notes: DRIVER FOR XP PRO SERVICE PACK 2

Hi:

That is exactly what I would have done, and how I would have gotten you the driver.

I have the PCI database bookmarked.

Good job!
