I've been having intermittent high spikes of lag/packet loss (similar to this thread) that have been getting increasingly worse over the past ~1 month. It's getting to the point where it's happening every 20 min or so. It's most notable when gaming, especially WoW, where everything will be working fine, and then all the sudden everything will freeze for 3-15 seconds before it seems to fast forward to the current game state, as well as google meet calls having sudden spikes of disconnecting for a few seconds during the work day (PST). This happens on wi-fi (asus ROG rapture GT-AX11000, plugged into 2.5g), ethernet plugged into my router(2.5 + 1g ports), and ethernet plugged in directly to the Xfinity gateway in my apartment. (1g port). Xfinity assistant just wants to restart my gateway everytime I try to troubleshoot, which hasn't helped the issue. The only thing I can find is high packet loss spikes when the issue happens. Can anyone help me?
