NetWrench: WiFi Speed Test

Speed test, WiFi analyzer and router setup: a professional network tool that anyone can use. No ads, and there never will be.
WAN MAC read straight from the router: MikroTik, OpenWrt, TP-Link, Tenda, netis, TrendChip, PIX-LINK.

SIMPLE AND PRO
Simple: speed, the connection check, Wi-Fi and your router. Pro: everything below. Switched in Settings.

WAN MAC
Read from the router over its management API, with a confidence level: CONFIRMED, LIKELY, UNKNOWN. The phone's MAC is not substituted for the router's.

ROUTER
Detection, vendor, model, firmware version.
The model described without a password from a catalogue: drawing, Wi-Fi bands and generation, ports, antennas, year, how current the hardware is; CPU, memory and power supply.
An unknown model can be sent to us with one tap: what the router shows without a login. Without Internet the report waits on the phone.
WAN connection type — DHCP, static, PPPoE, PPTP, L2TP: read on all supported vendors, written where the vendor's API allows it.
Wi-Fi: SSID, password and security mode in one atomic request.
QR code for the router's Wi-Fi.
Factory Wi-Fi profiles: save one, apply it to another router.
Initial admin password setup.
Interfaces and link state, DHCP, DNS, reboot — where supported.
LAN address and DHCP range, the range following the address when it moves — where supported.
Changing the WAN MAC, where the vendor's API allows it.
Router selection when several are chained.
The available operations depend on the model; only those the detected router supports are offered. Credentials are stored in the Android Keystore.

WI-FI
Survey: channels, signal level, band, security. Radios grouped into physical access points. Channel recommendation from measured data.
Link details including the negotiated channel rate. Channel rate and throughput are kept separate.
Coverage map from a walk through the home: signal by room, access point zones, moves between them. Advice when the phone holds on to a weak point beside a stronger one.

MOBILE
Operator, network generation, band and frequency, cell identity, signal level: RSRP, RSRQ, SINR. Neighbouring cells, timing advance and the distance it implies. Both SIM slots, with the one carrying traffic marked.

INTERNET SPEED TEST
Download, upload, idle and loaded latency, jitter — against a public edge, no server of ours in the path. Bufferbloat measured as the delay the link's own queues add when it is full. Which edge answered and where it is. Run chart; full version: both directions at once. History of previous runs.

NETWORK
Network scanner: address, MAC, vendor by OUI, name.
Port scanner.
Ping: latency, loss, jitter.
Traceroute on native ICMP, carrier-NAT detection.
Wake-on-LAN.
Ethernet over a USB adapter.

IPERF3
Built from upstream sources, client and server.
Server mode: measure into the phone with a standard iperf3 client.
TCP, UDP, reverse, bidirectional, parallel streams, configurable duration.
UDP: jitter and packet loss.
Results shown against the negotiated channel rate.

DIAGNOSTICS
Sequential checks: connection, gateway, DHCP, DNS, Internet access, latency, packet loss, throughput. Verdict and threshold for each.

TERMINAL
SSH and Telnet to a router or host, host key checking, adjustable font size.

BOOKMARKS
Router web interfaces and other addresses, opened inside the app in tabs. A proxy per address. Userscripts for those pages: installed by address, by pasted text or from a catalogue, updated by themselves.

TOOLS
MAC and subnet calculators. Speed indicator in the status bar, traffic counters.

PRICE
Free. All measurements and tools are unlimited; per day: configuring two different routers, two iPerf3 runs and two terminal sessions. The full version lifts the limits: a one-time purchase, no subscription.

Dark and light themes. English and Russian.
No accounts, no analytics. Nothing leaves the device unless you send a router report. Root is not required. Values Android or the router does not provide are shown as unavailable.
