I am currently living with my parents who use the AV500 TL-PA511 kit. My room and work area are WiFi deadzones so I want to buy a powerline adapter to extend the wifi range to my room that also has an ethernet port for my PC. I recently bought the TL-WA850RE without realising it didn't work through the powerline and was wireless, so I'd appreciate an alternative.
If any of the powerline adapters still being sold are compatible with the TL-PA511 please let me know. I understand it's very old so this may not be possible but I thought I should check first.
