Ethernet delivers lower, more consistent latency than
Wi-Fi because a cable doesn't fight walls, microwaves, or the neighbor's router
for airtime. Wi-Fi 6 and 6E narrow the bandwidth gap for most games, but
competitive titles still feel the extra jitter a wireless signal adds.
How
much latency does Wi-Fi actually add compared to Ethernet?
Wired connections typically run under 1ms of added
latency at the network hop. Wi-Fi 6 adds roughly 5 to 15ms depending on router
distance, channel congestion, and interference from other 2.4GHz and 5GHz
devices in the house. That gap sounds small until you're trading shots in a
128-tick match where every millisecond of input lag stacks on top of your
monitor's response time and your GPU's render time.
Does
Wi-Fi 6E close the gap for competitive gaming?
Wi-Fi 6E opened the 6GHz band, which cuts down on
congestion from older devices that can't use it. That helps bandwidth. It does
less for jitter, which is the real problem in competitive play. Jitter is the
variation in latency from one packet to the next, not the average latency
itself. A connection that averages 10ms but swings between 4ms and 22ms will
feel worse than a steady 15ms wired connection, even though the average looks
fine on paper.
What's
the real difference in packet loss and stability?
Ethernet's packet loss rate sits close to zero in a
properly wired home. Wi-Fi's packet loss climbs with distance, wall count, and
interference, and climbs further on crowded 2.4GHz bands common in apartments.
Packet loss shows up as rubber-banding and rejected inputs, not stutter, which
is why it's often blamed on the wrong component. Stutter is a RAM, storage,
thermal, or driver problem. Dropped and resent packets are a network problem,
and no GPU or CPU upgrade fixes it.

Should
you run Ethernet, Wi-Fi, or both?
Run Ethernet to the gaming PC if you play ranked
shooters, fighting games, or anything where a 10ms swing changes the outcome.
Wi-Fi 6 is fine for single-player titles, co-op games with generous netcode,
and anything where frame rate matters more than round-trip time. Most
households don't need an all-or-nothing answer. Run a cable to the one machine
where latency decides matches, and let everything else, phones, laptops, smart
TVs, stay on Wi-Fi.
If a cable run isn't practical, a wired powerline
adapter or MoCA adapter over existing coax beats Wi-Fi for stability, though
neither matches a direct Ethernet run.
