Public bug reported:

===
QNetworkInfo::NetworkStatus
QNetworkInfoPrivate::getNetworkStatus(QNetworkInfo::NetworkMode mode, int
interface)
{
switch (mode) {
case QNetworkInfo::WlanMode: {
if (interface < networkInterfaceCount(QNetworkInfo::WlanMode)) {
QString fileName = (*WLAN_MASK()).at(0);
fileName.chop(1);
fileName.append(QString::number(interface));
QFile carrier(*NETWORK_SYSFS_PATH() + fileName +
QStringLiteral("/carrier"));
if (carrier.open(QIODevice::ReadOnly)) {
char state;
if ((carrier.read(&state, 1) == 1) &&
(state == '1') &&
(networkSignalStrength(QNetworkInfo::WlanMode,
interface) > -1)) {
return QNetworkInfo::HomeNetwork;
}
}
}
return QNetworkInfo::NoNetworkAvailable;
}
===
The issue is that networkSignalStrength reports -1 with mako, as
/proc/net/wireless fails to report the right signal strength for it.
