Secure WiFi Connected but No Internet Solved

Question

Hello,

For the past 2-3 days, I've been unable to access the Internet, except occasionally, and I have no explanation for this.

My WiFi connection is marked as "Connected, secured" but when I use Opera or Chrome to browse, it tells me that there is no connection.

In the TCP/IPv4 settings, I have checked "Obtain an IP address automatically" and the same for DNS servers. I have the same setup on another laptop and it works perfectly on WiFi, just like another desktop, a tablet, or all the smartphones in the house. Only the desktop in the bedroom does not work even though, at first glance, the settings appear to be the same.

It's also worth noting that the problem occurs with Ethernet as it recognizes the network (in network connections), but it indicates that there is no Internet.

And maybe in an hour, nothing will have changed in the settings but everything will be working perfectly, and then tomorrow we start all over again, unable to get it to work...

I really need your help, I absolutely cannot see where this issue might be coming from!
Thank you very much!

Hello,
Update the drivers for your WiFi and Ethernet network cards, go to this site if you don't have a connection to perform the offline detection (second paragraph), or if you are connected, install the agent then perform a detection. Once the detection is done, you will have the list of drivers that are not up to date by clicking on the My Drivers tab.

re  ok, Ethernet seems to be working fine for now  Is the Ethernet connection still working properly?

re

there is no driver for W10 for DWA-556

For the past 2/3 days, I have been unable to access the Internet, except occasionally, and I have no explanation for this.

Were there any W10 updates before your problem appeared?

Have you tried a system restore to a date before your issue?

re  I believe there has been an update, yes indeed, and no, I have not tried to restore the system.   ok  Do you think that's an effective solution? I mean, I would prefer to find out the why and how to make sure to solve the problem effectively and understand it ^^   I searched "high and low" and I can't find a driver for W10 for your Wifi card >> D-Link DWA-556  I think the update(s) have "damaged" the driver for your Wifi card  As for system restoration, your files will not be "touched"  However, the update(s) will be reinstalled  Check if you have any updates in Windows Update regarding your Wifi card before executing a system restore  @+  -- the radiation level is higher at the unemployment office than at Chernobyl

I'm doing a restoration today, at least I'll get Ethernet back  Okay, let me know how it goes  Talk to you later  -- The radiation level is higher at the employment center than at Chernobyl

I installed the latest drivers, same thing.   Did you get them from the manufacturer's website?  Talk to you later  -- the radiation level is higher at the job center than in Chernobyl

billmaxime · Answer

For the WiFi card, the D-Link site provided nothing, so I uninstalled the card and reinstalled it using a supplied CD, along with the latest drivers. Okay, and what operating systems are on the CD?  @+  -- The radiation level is higher at the unemployment office than at Chernobyl.

re

Windows 7/Vista/XP

Do you think it makes a difference? It was working very well last week.

Yes, because you would need the drivers for W10

What OS was your PC running on before you "migrated" to W10?

How long has your PC been running on W10?

On Ethernet, if you right-click the network icon in the taskbar and choose "troubleshoot problems," what does it say?

Talk to you later

re  for the Ethernet driver, do a search with Drivers Cloud since the wifi is working  let me know what it gives  @+  -- the radiation level is higher at the employment center than in Chernobyl

billmaxime · Answer

re

for Ethernet, download this driver to your desktop click here

it's a "zipped" driver, you need to "unzip" it with 7ZIP (for example)

the link if needed >> https://www.7-zip.org/

PS: take the 64-bit for your PC

when the driver is unzipped, double-click on the file and run the SETUP as "administrator" (right-click)

let me know how it goes
