[Risolto] WIFI non funzionante dopo aggiornamento a 22.04

[stevini]

Salve. Dopo l'aggiornamento a Ubuntu 22.04 la connessione Wi-Fi quasi non funziona più. Si connette per pochi secondi appena avvio il pc dopodichè la connessione salta e non posso più fare niente.
Aspettavo paziente un qualche aggiornamento che avesse risolto la cosa, ma ancora nulla.
Qualche idea?

in breve il kernel attualmente disponibile per Ubuntu 22.04 (5.15.0-27-generic) ha dei bug per quanto riguarda la gestione della rete.

Dovevi modificare il post precedente, non farne uno nuovo...

[stevini]

chiedo scusa, era da tanto che non utilizzavo il forum e non sapevo come modificare il post precedente. Qualcuno ha qualche idea di come poter risolvere questo problema? che sia dato da vecchie installazioni nelle precedenti versioni di ubuntu?

[trekfan1]

Se provi da LIVE (ovviamente della 22.04) funziona?

Le schede di rete sono a posto.

Hai provato da ''Gestione Driver'' se c'è un Driver da abilitare?

[stevini]

Ho controllato i driver e non mi da nessun driver da installare a parte quello della scheda grafica.
Dopo aver dato:

Codice: Seleziona tutto

sudo sysctl kernel.dmesg_restrict=0

questo è l'output che restituisce al comando sucessivo:

Purtroppo non ho risolto. Neppure dopo il riavvo.
Ed aggiungo che sono connesso tramite tethering USB dal mio cellulare connesso al WIFI di casa.

Ed aggiungo che sono connesso tramite tethering USB dal mio cellulare connesso al WIFI di casa.

non capisco, il PC è connesso tramite USB al cellulare? Se è così il problema non è nel PC ma nel cellulare.

[stevini]

il pc lo connetto tramite USB al cellulare perchè da quando ho aggiornato a 22.04 il WIFI non funziona. Si connette al WIFI per pochi secondi dopo che avvio il computer, dopodichè, pur rimanendo connesso al WIFI di casa, non riceve nulla e sul browser mi visualizza "nessuna connessione internet".

@stevini lo so che porta via tempo, ma hai letto il contenuto dei link che ho postato? C'è anche un link https://askubuntu.com/ inserito da @Janvitus

C'è un bug con alcuni driver e il kernel predefiniti della 22.04, prova questo: https://askubuntu.com/a/1403963

Altrimenti aggiorna il kernel.

[EDIT]

Ad oggi 24/05/2022 su Ubuntu 22.04 il kernel è stato aggiornato alla versione

Codice: Seleziona tutto

uname -a

Linux ubudsk-2204 5.15.0-33-generic #34-Ubuntu SMP Wed May 18 13:34:26 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

non ho modo di verificare se sia stato implementato un qualche fix in merito a questo problema.
