I have two gaming PCs at home, and only my one is acting slow when we play online together. Even though my ping stays low, I get constant lagging and rubberbanding. My internet speed is 350Mbps over Wi-Fi, but I can't connect to the modem via Ethernet because of where it is placed. I've tried almost every common fix already: checking for viruses, restarting the modem, resetting network adapters, updating drivers, clearing the TCP/IP stack and DNS settings, changing the Wi-Fi antenna. I'm not a networking expert at all, so I don't really know what else to try. Please tell me if there are other things I should be doing or any suggestions you have since this has been happening for a year after moving in. Even though I've tried several times, I still haven't found a working solution.

Changing the wifi antenna doesn't fix much because it only picks up signals from neighbors. Sometimes pc settings can cause this, but most often, it's just the wifi itself. Instead of wasting time trying to tweak things yourself, you should test with ethernet instead. Moving a cable over the floor or moving the pc closer to the router isn't really necessary long term; that's just to make sure it's not the wifi. You might be asking if you want to reinstall the OS and find out nothing helps? Have you tried running a ping command in the background? Usually, you'll see spikes or packet loss when there is a network problem. It could just be some video settings too; for example, if your frame rate drops by 5 frames, it might feel like lag.
