Toshiba Satellite W7 and WiFi Disabled

Hello,
this is no longer possible because I no longer have the Windows manager to see the different available networks.
In fact, this IP conflict is the triggering event of my problem, but it's probably just a coincidence.
I am currently downloading the latest live version of Ubuntu to boot into Linux and see if my card is not dead (the indicator light comes on when the computer starts, which makes me doubt that the card is dead).

I really don't want to take the PC in for warranty repair knowing that I use it every day for my work, and I can't really wait 3 weeks.
So at worst, I will replace the Wi-Fi card; I don't think there's a direct access hatch. This is going to complicate things quite a bit.

I have tried reinstalling the drivers for this Realtek 8191SE card to try to wake it up but to no avail.

I will update as soon as I try Linux live.

Here I am on Linux at the time I'm writing, I typed the command lspci -v to get the listing, so I don't know Linux at all, so if someone can help me decipher:

I only included what seems interesting to me, I can include everything upon request,

So under Linux it doesn't detect the card, knowing that the drivers for Linux don't exist yet (from what I've understood).
It is possible to use the drivers for Windows 2000 with some manipulation, but it becomes a bit complicated for a Linux beginner, so I remained with the hardware log under Linux.

Now under Windows, it doesn't seem to me that it's "Flash Cards ..." that manages the keyboard shortcuts but rather "Hotkeys utility"

I do have the utility installed for the keyboard shortcuts since the "Fn" key works.
Config Free is also installed.
By the way, the "Connectivity Doctor" utility provided me with a log where the card appears

re .

Indeed, it is quite possible that you have a software called hotkey utilities that manages keyboard shortcuts, but it still seems to me that the wifi and other settings are still configurable via the flashcards, so undoubtedly these two utilities are linked, even if I cannot be 100% sure that they are indispensable, I was just asking the question to know if one of the two had not been uninstalled.
As for the FN + F1, F2, F3... keys, are you sure they all work properly and that they have the function that is normally assigned to them?
Because according to the logs you are able to produce, your card is still present and detected, but seems to be disabled by one or the other of the utilities.

By the way, upon rereading your post 1, you said:

On the other hand, I have an orange wifi indicator that now only lights up at boot, and goes out as soon as Windows 7 is launched, and does not turn back on afterward.

This would confirm that your card is indeed present and functional, but that once Windows is loaded, a software would disable it.

I have no further answers to provide you except that I strongly doubt a real hardware problem. Just a bad software configuration at most.

The question would therefore be, have you uninstalled one or more Toshiba original software? Because all of this seems mysterious to me.
