TL-WPA4220 V4 Problem with the connection since one week ago
I have a TL-WPA4220 for about a year, and during that time, I had no issues with both Wi-Fi and Ethernet connections working properly. However, approximately a week ago, I started experiencing problems with the device's connection. I tried connecting both adapters in the same room, and they worked fine. But when I move the extender to my bedroom, it loses the signal. Sometimes, it provides a very slow internet speed, and after a few minutes, it loses the signal again, I have tried connecting the extender in other rooms of the house, but it still doesn't have a signal. However, the LED lights indicate that it is linked correctly. I have also tried updating the firmware and restoring the factory settings.
