Hi@Pascal05,

Here are some suggestions may help you:

• Disable save mode

 You can disable it using the tpPLC utility. Refer to this FAQ for detailed instructions: How to enable/disable power saving mode on powerline adapters

• Check Lease Time Configuration:

​​​​​​​The DHCP lease time of 130 seconds is very short. If possible, log into your ISP modem/router and increase the lease time to a more standard value (e.g., 24 hours). This will reduce the frequency of DHCP requests.

• Static IP Configuration:

You've assigned a fixed IP address to your WPA4220. Ensure that this IP is outside the DHCP range of your ISP's modem/router to avoid conflicts. For example, if your DHCP range is 192.168.1.2 to 192.168.1.100, you can set your WPA4220 to something like 192.168.1.200.

• Reboot Devices:

After making changes to configurations, reboot both your ISP modem/router and the WPA4220 to ensure that all settings take effect.

• Check for IP Conflicts:

Monitor the devices connected to your network to ensure no two devices are trying to use the same IP address. This can cause connectivity issues.

• Consider Factory Reset:

If the problem persists and you have exhausted all options, consider performing a factory reset on the WPA4220 and reconfiguring it from scratch.

For TL-PA4010 (the models which start with TL-PAxxxx), press and hold the Pair button for 15s until all LEDs turn off and then come back on.For TL-WPA4220 (models beginning with TL-WPAxxxx), press and hold the Reset button for 10s. Release the button and all LEDs turn off. When the LEDs turn back on, the reset process is complete.
