Hello folks,
I have a problem: my computer suddenly can't find my Wi-Fi anymore (it worked before). I've tried a lot of things, restarted the Wi-Fi router, entered the Wi-Fi manual, reset the network settings, etc. I don't know what to do.
I hope someone can help me!
Thanks in advance!!

Good Morning, I just don't know what to do anymore… I've had a bad ping (80-200+) every evening for about a year now, and now it's even happening all day long… We've already called Vodafone, but they've said nothing more than "There's nothing wrong with the lines, but unfortunately we can't help you further." Maybe…
Hey, so at our Netto supermarket, there's a customer Wi-Fi service. It's sometimes a bit slow—presumably because the DSL isn't that fast. But yesterday I couldn't connect to the Wi-Fi at all. I told the employee at the checkout that the wifi wasn't working and he said he knew it was weak at the moment…
I live with my grandparents, who have a landline phone but no Wi-Fi. How do I know if I'll have internet if I buy a router and connect it with a DSL cable? Neither of them knows anything about this, and asking them if they have internet wouldn't help. Thank you for any help
Hello, A while ago, I bought a wireless card and installed it on my motherboard. Then I properly installed the correct drivers and restarted the computer. At first, it worked; I was able to access my Wi-Fi with the card. Five seconds later, I got a blue screen with the message "BUGCODE_NDIS_DRIVER." After that, I…
The PC is really “restarting” so that it actually restarts all (also the WLAN drivers). Please do not confuse, with “Hunterfahr” and “Start”, because the WLAN drivers are not loaded again, but only a snapshot is used by the driver memory. Because after automatic driver updates (Windows Updats), the driver must sometimes be reloaded to the memory.
Evtl. the WLAN adapter (see Windows Device Manager) cannot support all WLAN channels, some devices (for the US market) do not support channels 13+14. Solution is then to set solid channels (at 2.4 GHz WLAN) 1.6,11 in the WLAN router, or to switch on the router “Canals 13+14”.
If the WLAN router might have got an update and your WLAN adapter (named model of the WLAN adapter, is also in the device manager) does not support modern WLAN encryption WPA2+WPA3.
Does the wireless LAN adapter look healthy in the Windows device manager, does it work according to Windows?
PS:
To check if the hardware of the WLAN adapter is still ok, start Windows PC in “safe mode with network support”. Because in safe mode, virus protection programs and VPN programs are not started (which can also cause this), then a WLAN adapter actually runs more reliably.
Good luck!
Hello,
Thank you for your detailed answer!
According to window, my WLAN adapter works perfectly (TP-Link Wireless N PCI Express Adapter)
How can I set the channels in the router? (WLAN Router is from Telekom)
Hello Carol044,
then you use a speedport? With these, you can set a fixed WLAN channel in the router menu under WLAN settings ->
Reports like it helped.
Best regards

Always install the latest driver from TP-Link, because only the driver from the manufacturer is the right driver. Windows only uses standard drivers and then report, everything okay! The manufacturer TP-Link has the right. Pay attention to the model:

Set Wi-Fi channels in the speed port:

PS:
Your N300 WLAN adapter supports only Wifi 4 N (2,4 GHz) it can not have a Wifi 5 AC (5 GHz).
It could also be that a mix of encryption (WPA2 + WPA3) irritates your WLAN adapter, then I would try the encryption in the router once on WPA2 (only).
Also, Wifi 6 AX to 2.4 GHz, can cause problems, then simply set on the router Wifi 5 AC (5 GHz) and WiFi 4 N (2.4 GHz), which is more compatible for older WLAN devices.
Good luck!
Good thing you gave a feedback!
So it was a unsupported WLAN channel (13,14)I wrote:

I have changed the WLAN settings to 2.4 and it works!!! Thank you, you really helped me!!
In the task bar, normally, as a network display, at least one Globus symbol > Click on > In the blue window shown thereupon click the button “Wi-Fi.
See picture example (Win10)
