Wi-Fi connection failure on Epson printers

Hello everyone. It had been a while since I posted here, because the last few months had been busier than usual. The problem I recently ran into was with an Epson L3150. I checked several things and nothing made the blessed printer work over Wi-Fi, even though I had configured it before and it had been working. Nothing had changed on the printer, no reset, nothing. It simply found the Wi-Fi network and, when connecting, failed. I tried configuring it over Wi-Fi with cable, WPS, through the network, everything failed.

The solution? I discovered that, for some reason, Epson network cards have trouble connecting to Wi-Fi networks whose channel is between 11 and 13. I opened the router settings and changed it to channel 10. Depending on each location, another channel may be better. After saving, guess what? Within 2 minutes the printer found the Wi-Fi network by itself.

After it found the network, I just used the installer and followed the steps.
