WiFi Lab Network Intelligence

WiFi Lab is a professional WiFi intelligence app built for anyone who wants to understand, optimise, and troubleshoot their home or office network. Every test runs entirely on your device — no data is ever uploaded or shared.

### 📡 WiFi Scanner
Scan all nearby networks and see signal strength (RSSI), band, channel, security type, vendor and AP manufacturer in real time. Filter by band (2.4 / 5 / 6 GHz), sort by signal or name, and instantly identify who your neighbours are sharing the airwaves with.

---

### ⚡ Speed Test
Measure your download speed, upload speed, ping and jitter against real Ookla servers. Saves your last 5 results so you can track performance over time. Your WAN IP and ISP are detected automatically.

---

### 📊 Channel Analyzer
See exactly which channels are congested and which are clear. The waterfall chart shows every network on your band with signal strength. AI-powered channel recommendations tell you the quietest channel to switch to.
