Hello,
I have a Toshiba Satellite L670D-159 laptop. Running Windows 7.
It was extremely slow, I just installed an SSD and it's working great.
I cloned the hard drive using Acronis True Image.
Before cloning, I "cleaned" the PC a bit by uninstalling unnecessary programs (Nero, Skype, Ebay, Bonjour, Myphotobook).
I also ran C. Cleaner to clean up temporary files and fix registry issues.
I also defragmented the hard drive. Everything was working very well.
Only then did I clone and install the SSD.
At first, I had no sound.
I figured out how to proceed on Crucial's website, and the problem was easily resolved.
However, I no longer have Wi-Fi.
The indicator is red. No network Wi-Fi search.
The Wi-Fi network is shown with a red cross.
I can't reactivate it.
I tried uninstalling Realtek and reinstalling without success.
Same for Windows network troubleshooting.
In the end, the diagnosis is that the network card is damaged.
I should specify that the Internet works perfectly with the Ethernet cable.
So, I would like to change the network card but I don't know where it is located on my PC. I have seen tear-down videos on the Internet but it's not the same configuration as my PC.
How can I find the precise plan for my PC model?
I found the user manual for the PC but not the layout of its architecture.
I tried reconnecting my original hard drive and booting from it to see...
The configuration is the same on this drive and a restore to an earlier point did not fix the problem.
I conclude that it's due to a mechanical issue and not software or components.
Can you help me?
Thank you in advance.

Hello,
don’t bother disassembling your PC, get a USB WiFi adapter, see this example. If you still want to take your PC apart, your network card looks like this:

A hello, a response, a thank you are always appreciated. -
Thank you very much for the tip. Good idea and inexpensive too!
If I go for this solution, can I be sure it will work even if my network card is dead?
Will it replace the component?
There won't be any compatibility issues, right?
If so, that's really ideal.
Otherwise, I know what the network card looks like and how to replace it; the thing is, I don't know where it is located in the PC...
I've started to disassemble it, but I can't remove the keyboard, and I don't want to force it.
That's why I would have liked to have the PC manual.
Is it available?-
It is located on the motherboard with two wires connected, usually one black and one white, held in place by one or two screws. However, if you don't feel comfortable dismantling your PC, the USB WiFi adapter solution is the best. There are no compatibility issues with Windows 7; it will be installed automatically. If you take the adapter I mentioned, you will find all the information, user manual, and drivers on the TPlink website:

Great! Thank you very much for your valuable help, it takes a weight off my shoulders. So I won't be dismantling the PC, it will be easier.
However, the product you mentioned is for USB 3, I think the ports on my PC are USB 2.
I saw that the TPlink exists in a version for USB 2 port.
I think I should go for this model instead:

What do you think?-
No problem, USB3 or USB2, everything is backward compatible. The adapter you're showing me is
less efficient; it doesn't support WiFi 5. You also have this adapter, which is more efficient than the one you showed me and smaller, it doesn't stick out too much from the PC. There are plenty to choose from; my only advice is to choose an adapter from a well-known brand. Avoid exotic brands.

Thank you so much, I ordered the latest model you recommended.
I'll let you know how it works once I test it on my PC.
Have a good evening -
Hello,
I received the TP Link nano model and installed it on my PC.
It's really tiny and doesn't get in the way at all.
The PC recognized it immediately.
I only had to enter the Wi-Fi key and password (as expected), and the network search started successfully right away.
Thanks for this great tip that solved my problem... and for not much money either.
Have a nice day.
