Hostname resolution is only available when the LAN gateway is used as the DNS server. - Widgets are updated only at scheduled intervals (e.g. every 5 minutes), so they can show outdated info. Open the app to get info updated in real time. - Data usage widget, full featured network state widgets and lock screen widgets are available only with the Pro upgrade
