So, I'm moving in a bigger flat, with 2,5 rooms instead of just the one I'm sitting in right now. I just noticed that in the room where I want to set up my pc there is no telephone line plug in the wall, and I don't want to put a long cable through the whole flat - so a WLAN solution is probably it. I already have a good router in my current flat that works well with my PS4, the only TCP/IP-cable connection is to the PC itself. I probably can buy some kind of WLAN receiver for my desktop pc to avoid a lot of cable mileage. Do you have any recommendations what would be a good receiver? Or should I avoid that at all costs because in your experience you always get shitty connections like that and I need to rethink in which room I place my desktop pc?
If the wlan receiver was included on your mobo i would say go for it but the cable is and always will be the best connection there is.You might get ping spikes packet losses with wlan connection especially with a cheap usb wireless stick receiver If you are really desperate for wlan look into PCI-E cards
Yea you are better off just buying a cable and dragging it through the wall. I had a wireless receiver for $50 and it was good for like the first few weeks. After that it went to shit. I would lose internet randomly, get 500 ping even though no one was using the internet. My router was in the next room over and it was complete shit. Once I moved to cable I have not lost internet once or got any lag spikes. IF you have an option to move your router to the room you want your desktop or to drag a LAN cable through the wall then i highly recommend that because it will save you time, money, and anger.
I'm not sure when you ended up doing, but if you have Coaxial cable(used for cable tv or satellite) in the room, you might be able to repurpose that with a MOCA to Ethernet adapter.
