Yes, you can turn off the power save feature on a TL-PA7020 using the TP-LINK PLC Utility. However, the exact steps may vary depending on the version of the utility you have installed. You should navigate through the utility's settings or options to look for a power save or energy-saving feature, and disable it if available. If you are unable to find the option, you may refer to the user manual or contact TP-LINK support for further assistance.
