How many Mbps / how many "K" lines do I need, or how can I have the fastest Wi-Fi? I have had problems with my Wi-Fi for a long time. I can't even watch a Twitch stream in squad mode without having internet problems. What is the best Wi-Fi I can get? There are 3-4 devices in the WLAN at the same time (of which at least 2 are used simultaneously).
Got a copper line.
Unfortunately there are a number of influential factors.
First of all: What kind of fixed network tariff or what bandwidth do you have?
Then the general rule is that a direct connection via LAN cable is always preferable to connection via W-LAN. If this is not possible, you should ensure that there are as few interfering influences as possible - e.g. Too many devices in the W-LAN, other devices that send interfering frequencies to the W-LAN or simply too many / thick walls.
With W-LAN repeaters you should pay attention to the maximum bandwidth they can transmit.
So-called mesh repeaters are better than conventional W-LAN repeaters. Unlike normal repeaters, which only "pass on" the signal, mesh repeaters build their own network and thus offer a much more stable and faster connection via W-LAN.
