Ancho de Banda (Mbps)Ancho de Banda
What does download speed in Mbps mean?
Megabits per second measures raw data payload capacity. To calculate actual file download throughput in Megabytes per second (MB/s), divide by 8.

Run a test for verdict.
How Network Speed Testing Works
Multi-stream HTTP throughput, RTT latency metrics, and jitter calculation.
Download Throughput (Multi-Stream)
To saturate the real connection capacity, the test executes multiple parallel HTTP GET streams against Cloudflare Anycast edge nodes. It calculates continuous transfer rate in Megabits per second (Mbps), filtering out TCP Slow Start for maximum accuracy.
Upload Throughput (Concurrent POSTs)
Generates high-entropy memory buffers and dispatches concurrent POST requests to evaluate your upstream pipeline under sustained transmission bursts.
Ping (RTT) & Statistical Jitter (σ)
Ping measures round-trip socket time in milliseconds. Jitter represents the statistical standard deviation across samples; low jitter (<5 ms) is essential for online gaming and VoIP.
Link Symmetry & Network Profile
Analyzes the DL/UL ratio. Modern fiber links (XGS-PON) deliver 1:1 symmetry, whereas cable/coaxial networks (DOCSIS) or ADSL exhibit heavy asymmetric ratios.
Connection Troubleshooting & Diagnostics
Two-tier resolution guide for bandwidth throttling, high ping, and jitter.
Issue 1
Download Speed Far Below Contracted Plan
⚡ Quick Fix:Connect via Cat 5e/Cat 6 Ethernet cable or switch to 5 GHz / 6 GHz Wi-Fi (2.4 GHz is congested and caps at ~40-60 Mbps).
🔧 Technical Fix:Verify Ethernet link speed negotiated at 1000 Mbps rather than 100 Mbps (bad cable). Disable third-party antivirus SSL packet filtering.
Issue 2
High Ping & Jitter Spikes in Gaming or Calls
⚡ Quick Fix:Pause background downloads, torrents, or 4K streams on other household devices sharing the router.
🔧 Technical Fix:Enable SQM (Smart Queue Management) with CAKE/FQ-CoDel on your router to eliminate Bufferbloat queue latency.
Issue 3
Packet Loss & Intermittent Disconnections
⚡ Quick Fix:Power cycle your fiber ONT/Modem for 30 seconds to refresh the PPPoE session and optical sync.
🔧 Technical Fix:Run `tracert 1.1.1.1` or `mtr` to pinpoint whether packet drops originate at the local gateway, OLT node, or ISP transit peer.
Issue 4
Upload Speed Asymmetry & Throttle
⚡ Quick Fix:Check whether your ISP plan is symmetric FTTH Fiber or Coaxial HFC (where upstream channels are limited by DOCSIS specs).
🔧 Technical Fix:Configure MTU to 1500 (or 1492 for PPPoE) and ensure TCP Window Scaling and offloading are enabled in network stack.
Did You Know? Fascinating Internet Facts
Curiosities about submarine cables, physics of fiber, and global bandwidth.
🌊
99% of Internet Data Travels Under the Ocean
Despite satellite communications, over 99% of all international data travels through more than 550 submarine fiber optic cables on the ocean floor.
💡
Light is 31% Slower in Fiber Optic Glass
In a vacuum, light travels at 300,000 km/s. Inside fiber optic silica glass, it slows down to ~204,000 km/s due to refraction index (n ≈ 1.47).

From 56 Kbps to 10 Gbps: 178,000× Leap
In 1998, downloading a 5 MB file on 56k dial-up took ~15 minutes. Today with a 10 Gbps fiber line, 5 MB downloads in just 0.004 seconds.
📊
How Much Data Does a Speed Test Use?
Running a speed test on a 1 Gbps line transfers over 1.2 GB of data in ~10 seconds to compute precise throughput without caching.

Latencia / Ping (ms)Latencia
What is Ping or network latency?
The transit duration in milliseconds required for an ICMP/TCP data packet to traverse from your client to a target host and return (Round-Trip Time).
JitterCalidad de Red
What is network Jitter?
Statistical variance in packet arrival latency over time. Elevated jitter (>15 ms) degrades VoIP calls, video streaming buffers, and multiplayer games.
BufferbloatEnrutamiento
What is Bufferbloat?
Severe latency spikes triggered when router packet buffers fill up during high-throughput saturation, unnecessarily holding packets in queue.
