ethernet controller fried?

post #1 of 5
Thread Starter 
hi my girlfriend has a sony vaio PCG-61A12L model laptop and all of a sudden the wifi stopped working.

she backed up all her files, and i tried reformatting it. to my dismay, on windows 7 which normally has ethernet drivers, it says the driver is not installed and investigating further, the entire bunch of network devices is not working properly.

like it legit says this device is not working properly.

so is this thing fried do you think? ive tried uninstalling drivers, downloading realtek ethernet drivers, and like i said i even reformatted it to see if it was a virus.

my options, that i think i have at least...
find a motherboard wether from a computer with a broken screen, buy a motherboard, or sell the thing for parts. seems fairly limited but she needs a computer for school and i need to get her up and running asap..

thanks for any input in advance!

Or just take out the wifi card and look/smell for scorch marks. the pop it back in, see if it just worked its way loose. Then look for another wifi card on Ebay before you go replacing a 100 dollar mobo

Sounds like you are trying to diagnose the wired interface.

What WLAN card is in there? The sources I can see indicate it came with a 'Intel® Centrino® Wireless-N + WiMAX 6150'

It isn't just the Wi-Fi card it's the entire network of items in the motherboard.

Devices that say "this device isn't using any resources because it has a problem" are as follows

Ethernet controller
Intel centrino wireless n + wimax 6150
Network controller
Pci device
Pci simple communications controller
Sm bus controller
Unknown device

I'm going to try any official downloads provided by Sony but it looks like something is fried

fixed it! the ethernet is not a realtek it is an atheros the new driver worked fine... a little surprised windows 7 didnt come built in with even a dumbed down wired ethernet driver that would work with it.
