Ubuntu 18.04 crasha completamente la rete

[ESOREL]

Ciao a tutti,
In poche parole, in maniera pseudo-randomica il mio computer desktop su cui è installato ubuntu 18.04 fa crashare l'access point wi-fi.
Non riesco a capire a cosa sia dovuto questo problema. So solo che se il desktop è spento e utilizzo per esempio il mio portatile windows o il mio smartphone, tutto funziona alla grande.
Il "pseudo-randomica" significa che a volte tutto questo non succede e posso navigare tranquillamente per molto tempo su qualsiasi pc, anche su quello con ubuntu.
Nella fase "cronica" del problema da nessun pc riesco ad accedere ai settings dell'access point digitando il suo indirizzo ip in un browser.
Sempre nella fase "cronica" appena spengo il pc ubuntu, tempo 10 secondi e la rete si riallinea ritornando attiva.

Alcune info:
-Il router è un Tp-link TD-W8970 con il firmware aggiornato all'ultima versione.
-Ho provato a testare il funzionamento disabilitando ipv6 sia da router che da ubuntu senza risultati apprezzabili.
-Ho provato a testare il funzionamento disabilitando DHCP da ubuntu senza risultati apprezzabili.

So che è un problema posto in maniera molto "niubba" e non sto fornendo molti dettagli tecnici, però sinceramente i sintomi del problema e la casualità dello stesso mi spiazzano completamente.
Potete aiutarmi?

-Ho provato a testare il funzionamento disabilitando DHCP da ubuntu senza risultati apprezzabili.

Il problema al 99,9% non è il DHCP.

Vediamo anche come è configurato il driver della scheda di rete WIFI

Hai per caso notato se il crash della LAN si verifica in situazioni particolari? Tipo che stai scaricando in modo massivo da Internet?

Il crash dell'intera LAN in genere deriva da un malfunzionamento del router (e non è escluso che la causa scatenante non sia una qualche interazione con il driver della scheda di rete WIFI del tuo PC)

Hai per caso notato se il crash della LAN si verifica in situazioni particolari? Tipo che stai scaricando in modo massivo da Internet?

Capita in maniera molto randomica, solitamente capita già subito dopo l'avvio.

Prova così, dai il seguente comando

Codice: Seleziona tutto

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf


riavvia il PC e controlla se la stabilità della connessione di rete WIFI migliora.

[ESOREL]

Provo a testare per alcuni giorni e ti faccio sapere.

Grazie mille intanto
