IPCONFIG - Media disconnected

Hello,
try this:

You go to "network connection" and check if your connection is grayed out (inactive) or not grayed out (active)...
Anyway:

Your connection is active if:
A cable is plugged into your card, and if at least one powered-on computer is connected to that same cable.

I have a problem with the connection. I would like you to understand the issue I am facing with the network; I need someone to help me, with a lot of patience. I hope we can work together on my problem.

My connection is indeed active then.
By the way, when I try to disable it to reactivate it afterwards, it shows me a pop-up:
"It is not possible to disconnect at this time. This connection may be using one or more protocols that do not support Plug and Play, or it may have been initiated by another user or by the system account."
options offered: [OK]

???!!! Do you see it or not?

Good evening! I had this connection problem with my phone on Wi-Fi with my Freebox.
I resolved it after a lot of searching.
Everything was working fine before and after restoring files, I was getting media disconnected when typing IPCONFIG in the command prompt.
I spent the whole day trying to find the real problem; I even thought I needed to replace the network card.
But no, on the laptop the card is connected, but when it comes to going online, it's impossible...
The problem was simply that I connected to my Wi-Fi network with an incorrect key; the network was showing me "connected": I ended up checking the key online via another computer and entered the correct key back in.
And everything is working like before...
Happy surfing and check your Wi-Fi key!

Is your card connected to an active network? Under XP or 2000, for your card to work, it needs to be plugged into an ACTIVE network.

I have exactly the same problem as someone else, does anyone have a solution please!!!!

ACER support :) I'm sorry, I can't see it anymore.

Network connection problem
By typing IPCONFIG at the command prompt
you read: media disconnected
you don't have to look long, the problem comes from the network card, it is simply disconnected.
Although it is visible in the device manager, you need to remove or uninstall it.
If it still doesn't work ==> replace it.
