Non sò qual'è lIP del router. Mi collego da cellulare tramite usb e non sò come vedere l'IP. Comunque ho provato a fare il ping a entrambi gli indirizzi e rispondono. A volte il ping a 8.8.8.8 ci mette qualche secondo quando la connessione non funziona.

Si il ping 92.168.42.129 risponde. Può essere che la connessione funzioni ma non naviga in internet. Il browser sembra che stia caricando e dopo un minuto dice che non riesce a collegarsi al sito. Ultimamente da anche un messaggio di errore dove dice che c'è stato un errore nel protocollo di rete.

Ethernet non sò se è attivo non l'ho mai usato wireless si.

Ho appena reinstallato Xubuntu perché ho avuto dei problemi. Adesso ho la versione 18.10. Il ping sia di 8.8.8.8. e google.it funzionano. Sia l'ethernet che wireless sono attivi. Ho provato da browser 92.168.42.129 ma non trova la pagina. Forse c'è stato qualche cambiamento dopo l'installazione.

Ho provato da browser digitare 192.168.42.5 ma si apre la pagina del sito che sto creando in locale. Di solito per vederlo mi collego alla pagina 127.0.0.1.

La wireless è wls1. Da browser non riesco ad accedere a 192.168.42.0. Mi stò connettendo da cellulare. Non sò se centra qualcosa.

Si da networkmanager vedo la situazione. Io mi collego dal cellulare o con il cavo o con il wireless. Non assieme. La rete wireless è wls1.

Sia da wireless che da cavo hanno lo stesso problema. Ogni tanto le pagine non si caricano. Anche se abilitati singolarmente

Il ping si blocca raramente e quando di blocca non riparte. Però se apro subito un altro terminale e faccio il ping funziona regolarmente. Device-1 e Device-2 sono wireless e Ethernet mentre le righe IF-ID-1: enp0s29u1u1 state: unknown speed: N/A duplex: N/A mac: b6:9b:2a:86:91:da compaiono quando mi collego al cellulare con il cavo usb. le ultime righe di dmesg sono:
