Wifi not working: LAN cable working though

@AjayLamba31 Has the wifi ever worked with the 7510?

@Joe Doe : yes it worked flawless for 4 months. 

@AjayLamba31 Hmm. If the WiFi at the 7510 not turn off, the password is not changed, I think about a hardware problem. Did you use only WPA2 security? If not, you should switch over to WPA2 only. A lot of devices have problem with WPA3 security.

My fritzbox dashboard shows Wifi is Off. And also there is nothing that shows sicherheit in the left pane.

Click on Wi-Fi Network to change the settings…

@AjayLamba31 Wifi don’t turn on, if you press the WLAN button on the Fritzbox?

@Joe Doe : no it didnot.
@schluej : yes. We did this and refreshed again. This worked then!!!
