JioFiber の実際の動き

Fibre to the home, ONT at the wall

JioFiber runs fibre into your flat and terminates at an ONT/router box. The optical line itself is usually excellent — when results disappoint, the last five metres (Wi-Fi, old routers, crowded bands) are almost always the culprit.

Your plan is a ceiling, Wi-Fi is the reality

A 300 Mbps plan over 5 GHz in the same room should read close to 300 in this test. Through two walls on 2.4 GHz, 80–150 Mbps is ordinary. Neither result is “wrong” — they measure different links. Test both to find where the drop happens.

Upload depends on your plan

Fibre can carry symmetric upload, but what your account actually allows is plan-specific. The upload tile on this test tells you the truth in six seconds — compare it against your plan’s fine print rather than assumptions.

期待できる目安

Wired result vs plan
Within ~10% of plan speed over ethernet
5 GHz Wi-Fi, same room
Roughly 70–90% of plan speed
2.4 GHz / through walls
Often 30–60% of plan speed
Typical idle ping
5–20 ms to metro servers
What a good result looks like
Ping ≤ 20 ms, jitter ≤ 5 ms, loss 0%

トラブルシューティング

JioFiber が遅く感じる理由 — とその対処

Wi-Fi is eating your plan speed

The most common JioFiber complaint isn’t the line — it’s distance, walls and the 2.4 GHz band. People pay for 300 Mbps and test at 60 Mbps from the far bedroom.

対処 — Run this test twice: once laptop-plugged-into-the-ONT-router with ethernet, once on Wi-Fi where you normally sit. The gap between the two numbers is your Wi-Fi problem — fix with 5 GHz, placement, or mesh, not a support call.

Bufferbloat: lag while someone downloads

Budget routers cope poorly when a fibre line is saturated — your ping can balloon by 100–300 ms the moment someone starts a big download, which is exactly when a game or call stutters.

対処 — Watch the “Under load” tile: +10 ms is great, +200 ms means bufferbloat. If your router offers SQM/fq_codel or QoS, enable it; if not, a router that supports it (or scheduled download hours) fixes ranked-night clashes.

CGNAT and strict NAT for hosting

JioFiber may place you behind carrier-grade NAT depending on plan and region — strict NAT in games, broken remote access to your NAS or cameras, no inbound ports.

対処 — Compare your router’s WAN IP with the IP shown in this test’s results. They differ → you’re behind CGNAT; ask Jio about public/static IP options if you host, or rely on relay-based services that don’t need ports.

ゲーミング判定

JioFiber でのゲーミング

JioFiber is an excellent gaming foundation: fibre paths give single-digit to low-teen ping to metro servers, and this test’s gaming tiles should read Excellent on a wired connection. The two things that drag JioFiber gaming down are Wi-Fi instability (fix: ethernet or clean 5 GHz) and bufferbloat (fix: SQM). If your wired result scores lower than Expected, the bottleneck is upstream routing — note the numbers and raise it with support.

良好な JioFiber の結果の目安

Ping ≤ 20 ms, jitter ≤ 5 ms, loss 0%

FAQ

JioFiber に関する質問

How accurate is this JioFiber speed test?

It saturates your line with multiple parallel streams against the nearest Cloudflare edge, measures upload separately, and discards connection warm-up — putting results within roughly ±5–10% of real line speed. For the cleanest reading, plug in via ethernet and close other downloads first.

Why is my JioFiber speed slow on Wi-Fi but fine on my phone?

Almost always band and walls. 2.4 GHz reaches further but caps low; 5 GHz is fast but attenuates through concrete. Test this page near the router on 5 GHz, then at your usual spot — if only the far spot drops, add a mesh node or move the router, not your plan.

Why is my JioFiber upload speed lower than download?

Check what your plan promises for upload first — it is plan-specific on many JioFiber tiers. If the plan says symmetric and this test shows upload far below download over ethernet, note both numbers (with time of day) for a support ticket; they’re exactly what the engineer will ask for.

Is JioFiber good for online gaming?

Yes — fibre carries low latency natively, and a wired JioFiber line typically shows 5–20 ms ping to Indian servers. The caveats are the ones this test surfaces: high “under load” latency means bufferbloat (fixable with SQM), and strict NAT means hosting won’t work without a public IP option.

What is bufferbloat and how do I fix it on JioFiber?

Bufferbloat is latency that spikes when your pipe is full — routers with oversized buffers queue packets instead of dropping them, so your ping climbs during downloads. The “Under load” tile measures it here. Fixes: enable SQM/fq_codel if your router supports it, use QoS rate limits slightly below your plan speed, or upgrade the router on high-speed tiers.
