this extender is working great, everywhere I plug in the house I have a stable wi-fi. But I have a problem, in summer I connect it in the patio, so outside of the house. I have started thinking about security issues. The wi-fi is very well protected with a strong password but what about the ethernet ports? If someone is coming there with a laptop, by simply connecting to the ethernet ports is easily connected to my network and can access everywhere inlcuding the router and CCTV. Is like haivng pulled an ethernet extension cable out of the house. So the question is: is there a way to disable the ethernet ports on the TL-WPA4220 extender? I have tried with MAC filtering but that applies only to the wi-fi, not the wired ethernet. Thanks.
