Wifi speed test by termux

**Conclusion (in one line)** Inside Termux you can get a reliable Wi-Fi speed reading by installing one of three CLI testers—`speedtest-cli` (Python), the official Ookla binary, or `iperf3`. `speedtest-cli` is the quickest to set up, while `iperf3` is the gold-standard if you control both ends of the link. --- ## 1. Quick-start: the 60-second “just show me my speed” method ```bash # 1) Update Termux repositories pkg update -y && pkg upgrade -y # 2) Install Python and pip (if not already) pkg install python -y # 3) Pull in speedtest-cli from PyPI pip install --upgrade speedtest-cli # 4) Run the test speedtest ``` Typical output ``` Download: 287.65 Mbps Upload: 96.14 Mbps Latency: 8.61 ms ``` The numbers reflect *current* throughput over your Wi-Fi link all the way to the chosen Speedtest.net server, so they include router settings, congestion, and ISP quality. *Why this works:* `speedtest-cli` is a Python wrapper around Ookla’s public API and runs fine on ARM/Android—as confirmed by multiple Termux-specific GitHub repos. --- ## 2. Alternatives worth knowing | Tool | When to prefer it | Termux install commands | Notes | |------|-------------------|-------------------------|-------| | **Official Ookla CLI** | You need raw JSON/CSV, server selection, or regulatory-grade accuracy | 1. `pkg install wget tar -y` 2. `arch=$(uname -m)` (should be `aarch64` on 64-bit phones) 3. `wget -O speedtest.tgz https://install.speedtest.net/app/cli/ookla-speedtest-1.2.0-linux-android-${arch}.tgz` 4. `tar -xzf speedtest.tgz -C $PREFIX/bin` | Same engine the Speedtest app uses; Reddit Termux users confirm it works after Android 10. | | **iperf3** | You want *LAN-only* Wi-Fi speed without ISP influence | `pkg install iperf3 -y` | Run `iperf3 -s` on a wired PC, then `iperf3 -c -t 30` on Termux. Anything >650 Mbps on Wi-Fi 6 @ 80 MHz is excellent. | | **fast-cli (Netflix)** | Lightweight download test without Python | `pkg install nodejs-lts -y && npm i -g fast-cli` | Uses fast.com’s CDN; guide available for Termux users. | --- ## 3. Reading and trusting the results 1. **Run at least two tests** and average them—Wi-Fi is bursty. 2. **Stay still** during the test to keep signal quality constant. 3. If `iperf3` beats `speedtest-cli` by a wide margin, the bottleneck is probably your ISP, not Wi-Fi. 4. Large gaps between *Download* and *Upload* on Speedtest usually point to ISP plan asymmetry, not router mis-tuning. --- ## 4. Automate daily logs (optional) Save this as `~/bin/wifi_log.sh`, make it executable (`chmod +x`), and add it to Termux’s `crontab -e`: ```bash #!/data/data/com.termux/files/usr/bin/bash timestamp=$(date '+%Y-%m-%d %H:%M') speed=$(speedtest --simple | awk '/Download/{d=$2}/Upload/{u=$2}END{print d","u}') echo "$timestamp,$speed" >> $HOME/wifi_history.csv ``` A quick `termux-cron start` will collect a CSV you can graph later. --- ## 5. Troubleshooting common hiccups | Symptom | Likely cause | Fix | |---------|--------------|-----| | `speedtest: command not found` | You installed with `pip` but `$PREFIX/bin` isn’t in `$PATH` | `hash -r` or reopen the session | | Speeds cap at exactly **54 Mbps** | Router still allows TKIP / WEP | Force WPA2-AES or WPA3 | | `iperf3` shows >400 Mbps but Speedtest <100 Mbps | ISP plan or modem link is the limiter | Check router WAN stats; upgrade plan | | CLI exits with “permission denied” on Ookla binary | Android 13+ blocks exec from sdcard | Move binary to `$PREFIX/bin` and `chmod 700` | --- ### Take-away Open Termux, run the four-line `speedtest-cli` install, and you’ll have trustworthy Wi-Fi speed numbers in under a minute. When you’re ready for pro-level diagnostics, add `iperf3` to separate router performance from ISP limits—then tweak away with confidence. 🚀
