Hello everyone
I have a VAIO VPCEB2L9E laptop running Windows 7 with a Wifi network at home. I used to connect normally, and recently, my connection has been blocking and I can no longer connect wirelessly. The network is there, the connection is there, but it’s in "Limited" mode. It used to work wonderfully before, and this problem has only occurred recently. I've looked for solutions on the internet, which is impossible since the problems usually suggested are effective for Windows XP, not Windows 7. I checked if the issue is due to a reconfiguration of the Wifi card installation, but I found that the software is working correctly. Currently, I’m using a cable connecting my Wifi to the box, and the connection works (but with a wire!). If you could help me? What should I do? Is it possible to resolve this issue? Thank you for your understanding

A NETWORK CONNECTION ISSUE BETWEEN YOUR WINDOWS 10 PC AND YOUR BOX?!
<_> Hello, I am a technician in Côtes d'Armor.
Since around December 1, 2016, I have had numerous clients (at least 20) experiencing a recurring network connection problem, either Wifi or Ethernet (network cable) these days, without any change that could explain it. Generally, a message appears stating that there is
"no valid IP configuration"
and the network connection icon at the bottom right of the screen (near the clock) shows that the connection is "limited or nonexistent"!
The problem seems to be mostly but not exclusively with Windows 10 and Livebox. I just contacted Orange Pro at 3901 on December 8, and they confirmed it!
Both parties are looking for a solution (new update) but no date has been provided for now... Let's hope Microsoft takes action, but logically it should be the Firmware of the Boxes that needs updating... Anyway, restoring the box to factory settings is useless since it will update itself and thus be back to the same issue...
ORANGE provides 2 solutions:
A] Temporarily assign a fixed IP address to the Ethernet or Wifi network card.
To do this:
1) At the bottom right next to the time, right-click on the network connection (small computer or sticks or quarter circles…)
or
Search in "Settings" (formerly Control Panel) then "Network and Internet" then "Ethernet," "Change adapter settings"
2) Click on "open Network and Sharing Center" then on the left click on "Change adapter settings"
3) Right-click on your "Ethernet" (Local Network) or "Wi-Fi" (Wireless) connection
4) Double-click on "Internet Protocol Version 4 (TCP/IPv4)" in the menu
If all is well, you should see a window with a 'general' tab and “Obtain an IP address automatically” checked (so that the box/modem router manages everything…)
5) Check the circle “Use the following IP address”
6) In “IP address:”, you must enter an unused address within the same range as your box (similar but with a different last number), for example, if you are with Orange, type “192.168.1.5” or another number at the end between 2 and 253; in “Subnet mask:” you should put “255.255.255.0”; in “Default gateway:” and “Preferred DNS server” you should enter your Box's IP address; in “Alternate DNS server:” you can, if necessary, put a DNS IP from your ISP (Orange…) or 8.8.8.8 (Google)
in short…
¤ If you have an Orange Livebox or an SFR Box from Altice =>
IP Address = 192.168.1.5
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.1
Preferred DNS Server = 192.168.1.1
¤ If you have a Bouygues Bbox =>
IP Address = 192.168.1.5
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.1.254
Preferred DNS Server = 192.168.1.254
¤ If you have a Freebox from Iliad =>
IP Address = 192.168.0.5
Subnet Mask = 255.255.255.0
Default Gateway = 192.168.0.254
Preferred DNS Server = 192.168.0.254

7) Confirm by clicking OK then OK, close the windows and try Internet again
8) Restart your computer
9) The connection icon at the bottom right of the screen near the clock should have returned to normal and if you try to open the Internet using your usual browser, it should work!
OTHERWISE:
B] Enter command lines:
1) Search for "Command Prompt MS-DOS" in the apps or in the search bar/Cortana assistant and right-click on it to “run as Administrator”
Or
2) Press the "Windows" key (the small flag between CTRL and ALT at the bottom left of the keyboard) AND simultaneously press the "R" key
Or
open "run" in the start menu
then type "cmd" and validate = press the "enter" key or click "OK"
A Command Prompt (black MS-DOS window) appears
3) There, type "ipconfig" or "ipconfig /all" for experts to see your IP address then validate
'-> if your IP address is not of the type 192.168.x.x but 169.x.x.x then that's the problem giving you a limited connection!
4) Try typing these commands, validating each one by pressing the “enter” key on the keyboard:
ipconfig /flushdns -> (clearing the DNS cache)
netsh winsock reset
netsh winhttp reset proxy
netsh winhttp reset tracing
netsh winsock reset catalog
netsh int ipv4 reset catalog
netsh int ipv6 reset catalog
netsh int ip reset c:\reset.txt -> (this resets the TCP/IP protocol)
5) Close the window and restart the PC
If it doesn't improve, try entering these command lines (repeating the previous steps to get the black window):
Type "ipconfig /release" and validate
6) Regardless of the result, then type "ipconfig /renew" and validate, then wait a few seconds for the text below to confirm or not the renewal.
7) Close the window even if you have an error.
8) The connection icon at the bottom right of the screen near the clock should have returned to normal and if you try to open the Internet using your usual browser, it should work!

Other avenues:
- Run the troubleshooting utilities 1-Network Adapter 2-Internet Connections.
Control Panel > search and resolve problems > View all
> Locate 1-Network Adapter > Click on this item and follow the instructions.
> Locate 2-Internet Connections > Click on this item and follow the instructions.
Update your network card drivers via Device Manager.
Perform the Internet connection settings reset procedure.
- Repair Windows 10 system files
In a command prompt as administrator, type the command "sfc /scannow" then press Enter.
- Repair the Windows 10 image using the DISM tool
In a command prompt as administrator, type the command "Dism /Online /Cleanup-Image /RestoreHealth" then press Enter.

Your post is a real useful contribution.
By the way,
thanks to Microsoft for making us regress by 5 years.
