    ugh. i keep reading guides that say to tweak network adapter settings for MMOs: disable interrput moderation, disable power saving, change buffers. Some of it sounds like cargo cult stuff 🤦 On a powerline adapter, what has actually helped you? And does updating TL-WN721NC Wireless N USB Adapter Driver matter?? Im especially interested in what you measured before and after, not just what felt better. If u tried a tweak and it did nothing, thats useful information too.

    Power saving on the adapter can cause periodic spikes. In Device Manager > adapter > Properties > Power Management, untick Allow teh computer to turn off this deivce, and check the Advanced tab for power saving modes.

    ahh classic to measure, run ping -t to your router and to an outside address at the same time while playing. if the router ping spikes too, the issue is local (Wi-Fi/driver/interference). if only teh outside ping spikes, its further out.

    yeahhh interrupt moderation tweaks can lower latency slightly but increase CPU usage. The differecne is usually small. Id only test it if uve ruled out bigger issues. worked for me anyway 🤷

    ok so for my main multiplayer game, the biggest latency factors are usually Wi-Fi interferecne, router bufferbloat and the route to the server. Drivers matter less, unless a specific version has a bug. Test with a wired conenction first if you can. worked for me anyway 🤷

    ive seen driver updates genuinely fix periodic spikes. background scanning behavior changes between versions.

    @juno.larsen Updated to TL-WN721NC Wireless N USB Adapter Driver 140915 and it fixed the periodic spikes. Release notes mentioned a background scanning fix.
