Cannot connect anymore to WIFi Extender WN3000RP V1H2

Hello,

I cannot connect anymore to my old Wifi Extender WN3000RP. Once pushing the reset factory button, I connect my PC to SSID NETGEAR_EXT. It connects but when opening the browser and selecting the URL indicated in user manualm I have different behaviours according to the browser. Firefox and Chrome simply cannot connect whilst Edge connects to device homepage but, once I push the button to continue, it cannot connect to next page exactly like the other browsers do for the homepage. Since this happened gradually (for some time the issue was present only on some PCs) I can guess that there was some support discontinuity to the device but I found no statement on the topic.

Could you please help me?

Thanks

Regards

Alberto
