I have a question about Wlan / Lan I play a lot in my free time but I have a problem with my ping my Wi-Fi is not bad but unstable and my ping goes up often because somewhere else in the house (but about the same Wi-Fi) someone watching Netflix, for example. My only direct LAN connection is unfortunately on the ground floor and I live on the first floor. Anyone has an idea how I could improve my Wi-Fi or some tip for a product (currently playing with Wi-Fi stick)
A Wi-Fi amplifier isn't really helpful for pinging. But there's also another possibility. You can google afterwards. In principle, you plug one adapter into the socket on your router and one on your PC. You can then plug a LAN cable into both.
If you still have questions, for example which Powerline adapter is suitable, I can of course also help you.
You will have to live with it that your internet will slow down if someone else cuts your bandwidth.
If you want to play close all other programs. Your ping doubles with a virus scanner, interrupt protection. Email program too. Disable firewall. Then you get maximum ping
Do not try to connect to 600 Mbit and such stories. 150 in the 5GHz band is sufficient and ensures sufficient stability.
