Repeaters were created for people like you, that is, undemanding users for whom the home network means access to the Internet and nothing else. Solutions based on one radio for reception and further transmission will always be unstable and susceptible to interference. Requires a suitable signal from the home router and trims speeds on the home network. They don't work perfectly well, they just work somehow. You write some nonsense about the risk of damaging devices on the LAN. The selection criterion is not aesthetics and lack of holes, but reliability, stability of the connection and high speeds, and these are provided by the cable today. And the internet in hot = spots has nothing to do with repeaters. A colleague on this topic https://www.elektroda.pl/rtvforum/topic3070553.html has found out how the repeater "works". If you know how, help him.
