Looking to installer log 'ubuntu_desktop_installer.log' i see a lot of messages like:
`DEBUG connect_to_internet: Update access points: [AccessPoint(ssid: corado), AccessPoint(ssid: TNCAP692D47), AccessPoint(ssid: WOW FI - FASTWEB), AccessPoint(ssid: Vodafone-A42750462_EXT), AccessPoint(ssid: Vodafone-A66133607), AccessPoint(ssid: Vodafone-A68737712), AccessPoint(ssid: Vodafone-WiFi), AccessPoint(ssid: TP-Link_5102), AccessPoint(ssid: TP-Link_Extender_5GHz), AccessPoint(ssid: D-Link-E278EE), AccessPoint(ssid: Direzione_Musel), AccessPoint(ssid: FASTWEB-NTWS7U), AccessPoint(ssid: AP_Fasce), AccessPoint(ssid: Internazionale SL), AccessPoint(ssid: AP_IAT)] (WifiDevice(vendor: Qualcomm Atheros, model: QCA9377 802.11ac Wireless Network Adapter, state: activated))`
