I got a free Wi-Fi repeater that costs 15 euro (from China). Unfortunately, I can't take a picture from the laptop and upload this here, but I think the price says what I'm holding in my hand. Before I install it and set it up, I wonder whether it would make any difference to use it or whether it is more of a jammer than an amplifier in practice.
While we're at it - what actually characterizes a good Wi-Fi repeater?
Of course anything is better than nothing
Can't be said across the board.
Try makes you smart!
So a repeater would be an example where this is not true.
A repeater can greatly degrade performance and not offer a single benefit.
A bad repeater can be much, much worse than none at all. If, for example, it does not meet current safety standards and your apartment burns out.
The price can, but does not have to be, decisive. There are good cheap repeaters and there are bad expensive repeaters.
YES: If you want to supply unsupervised or very poorly supplied areas of an apartment with this Wi-Fi repeater, you can use it.
NO: If you already have a reasonable or good Wi-Fi reception (more than 70%, 3 of 4 lines), then leave out the repeater, it will hardly be of any use, it could even become slower.
NO: If it does not support the WPA2 WLAN encryption.
You can try it out, you can always switch off, so if it hardly improves anything, you better leave it out.
PS:
You can name the model and manufacturer (there's always a sticker on it), then they will help you with problems.
