Run the test above for at least 60 seconds. Here is what each
number means for this game specifically.
Packet loss (what the Wi-Fi marker is really about)
Wireless links retry silently and lose packets in bursts. Rollback absorbs latency gracefully and bursts of loss badly, producing corrections large enough to move a character across the screen. The indicator is a warning about loss, not about ping - which is why a wireless opponent with a good ping figure can still be unplayable.
Jitter (sidesteps that stop working)
Tekken's sidestep depends on your position relative to an attack's tracking, evaluated on frames that may be rolled back. When corrections vary in size, a step that cleanly avoided a move gets re-simulated into one that did not. This is the most Tekken-specific symptom of an unstable line.
Ping (and punish windows)
One frame is about 17 ms at sixty frames per second. Most of the game tolerates a few frames of prediction without complaint. Where it bites is the punish game: a move that is minus thirteen on block is a specific, learnable window, and reacting to it through several frames of prediction is a genuinely harder task.
What you see in game, and which number on this page explains it.
Fighting games are the hardest genre to network well, because they are the only one where a single frame reliably decides the outcome and where both players are acting continuously rather than taking turns. Rollback is the accepted answer: predict, simulate forward, and rewind when the prediction was wrong. It works because predictions are usually right, and it degrades gracefully as long as the truth arrives roughly on schedule.
Tekken adds an axis that makes the failures easier to see. In a 2D fighter, a mispredicted position is a character standing a little further left or right than expected. In Tekken, movement includes sidestepping into and out of an attack's tracking, so a correction does not merely move the character - it can change whether an attack was going to connect at all. The same size of network error produces a more consequential visual result.
This is the real content of the Wi-Fi indicator. It is not a statement that wireless is slower, because often it is not: a modern wireless link can show a perfectly respectable ping. It is a statement that wireless links retry, and that retries mean packets arriving in clumps or not at all, and that clumps are exactly what turns small rollbacks into large ones. The community arrived at this conclusion empirically long before the games started labelling it.
The practical upshot is that the three numbers on this page should be read in reverse of the usual order. Loss first, because it is what rollback cannot fix. Jitter second, because consistent prediction depth is what makes a match feel offline-like. Ping last, because a few frames of it is precisely the problem rollback was invented to solve, and it does that job well.
If the chart above shows packet loss or high jitter, work through
these in order.
Why does Tekken 8 show a Wi-Fi icon?
Because wireless connections lose packets in bursts, and bursts of loss are the one thing rollback netcode cannot absorb smoothly. The indicator warns other players about a problem that a ping number would not reveal.
Does rollback make ping irrelevant in Tekken 8?
It makes ping far less important than it used to be, not irrelevant. Prediction hides a few frames very well. Reaction punishes are where the remaining frames are felt, and packet loss is where rollback stops helping entirely.
Why do my sidesteps not work online?
Sidestepping depends on your position relative to an attack's tracking at specific frames, and those frames can be rolled back and re-simulated. An unstable connection changes the size of those corrections, which turns a clean step into a clipped one.
What connection do I need for ranked?
A wired one first, and a stable one second. The absolute ping matters less than whether it is steady and whether packets arrive. Run this test for a few minutes and look at loss and jitter before you look at the ping number.
