Can’t connect to wifi on my desktop

Question

Can’t connect to wifi on my desktop

Cas Rijnierse 0

I was playing a game of chess when suddenly my screen went dark. When it went back up again I lost my wifi connection and it hasn’t worked since. The wifi adapter seems to be doing fine. The troubleshooter says that either “can’t reach default gateway”, “can’t find dhcp server” or “connected to internet” but still no websites are loading and are giving me err_network_change, dns_probe_finished_no_internet, or err_failed. I already did a network reset,restarted the networkadapter, used a manually set ip adres, tried several command probes (release, renew, netsh winsock reset, etc). Nothing works. Also when the troubleshooter says that I am connected, nothing works. I use windows 11.

Thanks in advance for the help.

Hi,

Is this happening with any Wi-Fi network or just your home network?

Have you tried connecting via cable to see if it works normally?

Do you have any third-party antivirus software?

According to the error, the problem might be DNS-related; have you tried using different DNS servers?

Thanks

Hi Ivan, thank you for the quick response. I am not entirely computer-literate, so excuse me if my answers don’t seem logical.

I tried earlier to connect my phone’s hotspot. It doesn’t work either.

I don’t have a cable, so I will have to buy one to check it out.

I don’t have any third party antivirus software.

Regarding the dns servers, I tried the 8.8.8.8 and 8.8.4.4 manually but still nothing. Now, the troubleshooter only says that it can’t reach the gateway and that it’s connected (but it still doesn’t work). I don’t see the dns server texts anymore.

Hi,

Try accessing the control panel > network and internet > sharing center > change adapter settings > right-click on the Wi-Fi adapter, go to properties, take a screenshot and post it here.

Do you know the model of the USB Wi-Fi adapter?

Thanks

Hi Ivan. I think the model of the USB wifi adapter is Intel(R) Dual Band Wireless-AC 8260. Unfortunately msft doesn’t let me add a screenshot because it is apparently larger than 3 mb. The IPv4 is checked and the IPv6 is not.

Hi,

Try reversing the process: check IPv6 and uncheck IPv4 and see if it recognizes the network.

Thanks

I switched the checks, restarted the pc, and now the wifi is gone all the way. There is no icon anymore to click on.

Hi,

I understand it's possible the adapter has a physical defect.

If possible, could you check the model without using the direct driver for the network adapter? It should show some information (TP-Link, MediaTek, etc.).

In Device Manager, check if it has a yellow exclamation mark.
