So when I freshly installed the Internet and did a speed test it was 225 mbits (with laptop via wlan) but when several devices had logged on to the Wi-Fi the value fluctuated once 28mbits (with the Ps4) once 58mbits (with my laptop) and mobile phone 117mbits) it is normal that it fluctuates (everything was via wlan no lan) or one shares the mbits with the people. I know that's complaining at a high level, but if I pay 40 euro for it, I want my full 250mbits ^^
The more devices use the line at the same time, the less is left for the individual. It is completely normal. You only have the full 250Mbit if you only use one device at a time.
You must not forget that you always make a compromise with Wi-Fi, and it is only possible to get the maximum bandwidth in an ideal environment. So, as always, I can only guess, if possible, pull a LAN cable into every room and connect a MESH repeater. So you can get the most feasible out of the WLAN connection!
