I use a Deco M5 and an Epson Wi-Fi printer on my home network.

Everything has always worked well, being able to print from various notebook devices and even directly from mobile phones).

However, after updating the last firmware of the Deco M5 (1,9,1 Build 20250909 Rel. 37570), notebooks and mobile phones can no longer connect to the printer.

The printer is not in problem, because I took it to a relative's house, and I installed it on the Wi-Fi of his house and it worked there.

I've already restored the factory configuration of my home router and recreated the entire network, but it's no use.

What to do TopLink?
