Android and Windows network diagnostics

Diagnose network issues from Android or Windows.

Free Android and Windows apps for Wi-Fi, Ethernet, LAN, DNS, HTTP, TCP/TLS, captive portal checks, and shareable evidence. Add the free local appliance when a site needs continuous telemetry, inventory, alerts, and reports.

InfraZoom Android app

The app is the first step for home checks and professional troubleshooting.

Use App Only mode when you need a fast answer from the device that is actually experiencing the problem. At home, it helps you understand your own Wi-Fi before changing routers or calling the ISP. In a professional workflow, it captures user-side evidence during a support visit: Wi-Fi signal, BSSID, channel, roaming, DNS, HTTP, captive portal behavior, public IP, recommendations, and shareable reports.

Quick Scan from the user location

Capture SSID, BSSID, RSSI, link speed, channel, IP/DHCP details, DNS latency, HTTP reachability, public IP, and captive portal status.

Wi-Fi Live and roaming analysis

Use the Wi-Fi hub for Live signal walk tests and nearby network analysis: RSSI, channel context, congestion, BSSID changes, and client-side symptoms.

Evidence without deploying hardware

App Only mode is useful before any appliance exists. It gives home users and support teams enough proof for many Wi-Fi and internet complaints.

Pairs with the appliance when needed

When a local appliance is deployed, the app adds Appliance navigation, pairing, health, reports, configuration, Site AutoTest, field tools, and phone-vs-site comparison.

Choose your path

Two ways to explain the same product.

Infracheck starts with a simple app for the person having the problem. The same evidence can then support a more formal IT workflow when a home, office, or customer site needs history, reports, and appliance telemetry.

HOME USE

Check your own Wi-Fi and network

Use the Android or Windows app to understand slow Wi-Fi, weak signal, DNS issues, captive portals, router reachability, and whether the problem is inside your home network.

Home workflow Slow Wi-Fi guide Quality test

PROFESSIONAL USE

Collect support-ready network evidence

Use App Only for first-visit diagnostics, then add the free appliance for continuous local telemetry, reports, and phone-vs-site fault isolation.

Professional workflow Local diagnostics Evidence reports

Windows app

Desktop diagnostics for PCs, wired links, Wi-Fi, LAN discovery, and evidence reports.

The Windows app covers the user workstation side: PC health checks, adapter details, Wi-Fi live views, Ethernet inspection, safe LAN discovery, DNS/HTTP/TCP/TLS tools, VPN/routes, DHCP checks, local history, and PDF evidence. Appliance mode stays optional and starts disabled.

Diagnose this PC

Gateway, DNS, HTTP, public IP, adapters, Wi-Fi quality, Ethernet status, routes, VPN, and safe tool-driven checks.

Wi-Fi and LAN proof

Nearby Wi-Fi analysis uses hashed SSIDs/BSSIDs in public screenshots. LAN discovery masks private addressing while keeping the workflow clear.

Evidence for support

Local history and PDF evidence help explain what was tested, when it was tested, and which fault domain is most likely.

Product

Three layers: app-first diagnostics, local appliance telemetry, optional premium operations.

Start with the free Android or Windows app. Add the free appliance for continuous site telemetry. Add Premium only when you need central operations across multiple customer locations.

Free InfraZoom by Infracheck

The primary field product: Quick Scan, Diagnose hub, LAN scan, Wi-Fi Live, nearby networks, captive portal detection, phone-side DNS/HTTP checks, history, share output, and PDF evidence.

Free Windows App

PC health checks, Wi-Fi and Ethernet diagnostics, safe LAN discovery, route/VPN/DHCP/TLS tools, DNS comparison, local history, PDF evidence, and optional appliance pairing.

Free Local Appliance

Docker-based monitoring for ping, DNS, HTTP/TLS, WAN speed, packet loss, LAN inventory, alerts, reports, history, pairing, local throughput, VoIP readiness, path checks, and appliance configuration from the app.

Phone vs Appliance

Compare what the user's phone sees with what the local appliance sees to isolate client-side vs site-wide faults.

Incident evidence

Create timestamped support snapshots with findings, charts, recommendations, and exportable reports for customer conversations.

Technician console

The app works standalone first. When paired with an appliance, it also becomes a mobile console for discovery, pairing, health, alerts, inventory, reports, configuration, Site AutoTest and field diagnostics.

Optional add-on

Premium License

Self-hosted central portal for multiple appliances, alert routing, white label, branded reporting, roles, API, and webhooks.

When to add the appliance

Add the appliance when a site needs history, inventory, alerts, and reports.

The free Docker appliance is not required for App Only diagnostics. Deploy it when a customer site needs persistent local telemetry after the technician leaves.

Connectivity checks

Scheduled ping, packet loss, jitter, DNS, HTTP/HTTPS, TLS expiry, and WAN speed checks.

LAN discovery

Device inventory, new devices, missing devices, hostname overrides, and technician notes.

Health intelligence

Health score, verdict engine, fault-domain hints, problem radar, recommendations, and triage board.

Reports and history

PDF reports with score cards, alerts, checks, graphs, inventory, min/avg/max statistics, and historical evidence.

Scenarios

Sales scenarios customers immediately understand.

These are the conversations Infracheck is designed to simplify: intermittent problems, unclear responsibility, no historical data, and customers asking for proof.

Scenario 01

"The internet is slow, but only sometimes."

The app gives immediate phone-side proof. If the issue needs history, the appliance tracks WAN speed, packet loss, gateway latency, DNS response, and HTTP reachability over time.

Outcome: prove whether the fault is ISP, gateway, DNS, Wi-Fi, or an external dependency.

Scenario 02

"Wi-Fi drops when users move between rooms."

The app records RSSI, BSSID changes, channel behavior, and roaming/handover results during a technician walkthrough.

Outcome: separate coverage, roaming, congestion, and client-side problems.

Scenario 03

"Something appeared on the network."

The appliance discovers LAN devices, tracks new and missing devices, and lets technicians annotate inventory.

Outcome: give customers inventory visibility without a heavy enterprise platform.

Scenario 04

"We need a monthly support report."

Generate customer-ready reports with health score, findings, charts, alerts, inventory, and recommendations.

Outcome: turn support work into visible value and renewal evidence.

Operating modes

Choose how much you deploy. Start for free.

Download the Android or Windows diagnostics app first. Add the container only when a customer site needs persistent local telemetry. Add Premium when you need centralization and automation.
