Question

I can get WiFi signal level in dBm using following code.

for (ScanResult result : wifiScanResultList) {
    int signalLevel = result.level;
}

Answer 1

You already have got the levels, So i will tell you how to classify that wifi into high,medium or low strength. Following is the code

int level = result.level;

    if (level <= 0 && level >= -50) {
        //Best signal

    } else if (level < -50 && level >= -70) {
        //Good signal


    } else if (level < -70 && level >= -80) {
        //Low signal


    } else if (level < -80 && level >= -100) {
       //Very weak signal

    } else {
       // no signals
    }
