Connessione va a tratti

[Cherubina]

Salve a tutte e a tutti.
Ho un problema con il mio portatile lenovo con Ubuntu 22.04 jammy: a tratti la connessione tramite wifi s'interrompe, come se andasse in freeze. Il simbolo del wifi diventa pieno, devo aprire impostazioni wifi e cliccare sulla connessione e scegliere annulla, così riparte. Succede a caso, sia con firefox che con chrome e la connessione va senza problemi con tutti gli altri dispositivi che abbiamo in casa.
Un anno e mezzo fa ho avuto lo stesso problema, era stato risolto grazie a questa discussione viewtopic.php?t=652151 , ho riseguito i suggerimenti, ma questa volta non si risolve.

Proviamo a disabilitare il protocollo di rete IPv6, vediamo se aiuta.

Con un editor di testi (Gedit ?) in modalità amministratore apri il file /etc/sysctl.conf

Codice: Seleziona tutto

sudo gedit /etc/sysctl.conf

e aggiungi le seguenti righe

Codice: Seleziona tutto

net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1
net.ipv6.conf.lo.disable_ipv6=1
net.ipv6.conf.wlp2s0.disable_ipv6=1

salva il file. Chiudi l'editor e riavvia il PC.

Il protocollo di rete IPv6 andrebbe disabilitato anche nelle proprietà della connessione WIFI che stai utilizzando, in Network Manager.
O lo fai tu dall'app di Network Manager oppure procediamo da terminale, ma mi serve prima questo output

nmcli connection

Già che ci siamo, disabilita anche la gestione dell'energia in Network Manager.

Con un editor di testi (Gedit ?) in modalità amministratore apri il file /etc/NetworkManager/NetworkManager.conf

sudo gedit /etc/NetworkManager/NetworkManager.conf

e aggiungi le seguenti righe

[connection]
# Values are 0 (use default), 1 (ignore/don't touch), 2 (disable) or 3 (enable).
wifi.powersave = 2

poi il solito ... salva ... chiudi ... riavvia il PC

[Cherubina]

Ho aggiunto le righe e ho disabilitato IPv6 anche da network manager e la gestione dell'energia.
Adesso provo per 24h se tutto funziona, poi ti aggiorno.
grazie mille per l'aiuto.

P.S. perché abbiamo disabilitato IPv6 e la gestione dell'energia? te lo chiedo per imparare.

P.S. perché abbiamo disabilitato IPv6 e la gestione dell'energia? te lo chiedo per imparare.

Perchè potrebbero influire negativamente sulla stabilità della connessione WIFI.
Stiamo andando a tentativi ...

Da Terminale controlla se il risparmio energetico Wifi è attivo con:

Codice: Seleziona tutto

iwconfig

Se è attivo prova a disabilitarlo da Terminale per vedere se funziona con:

Codice: Seleziona tutto

sudo iwconfig wlan0 power off

Se non dovesse funzionare lo riattivi con:

Codice: Seleziona tutto

sudo iwconfig wlan0 power on

Provato già a cambiare canale Wifi dal Model/Router?

[Cherubina]

si, stesso problema.
però da ieri sera, dopo le indicazioni di Teche non l'ha più fatto.

[thece]

@Cherubina dai tuoi output vedo che:

- te ne sei dimenticata qualcuno
- non hai modificato la gestione dell'energia in Network Manager

...
Già che ci siamo, disabilita anche la gestione dell'energia in Network Manager.
...

A parte questo, come sta andando?


@OMBRA_Linux il nome logico associato alla scheda di rete WIFI di @Cherubina è wlp2s0 , NON wlan0

Provato già a cambiare canale Wifi dal Model/Router?

L'output sopra è parziale ma non mi sembra che ci sia forte sovrapposizione dei canali WIFI

Codice: Seleziona tutto

nmcli -p device wifi list ifname wlp2s0

comunque il router di solito è impostato per modificare automaticamente il canale nel caso rilevi forti sovrapposizioni

ero convinta di aver disabilitato anche la gestione dell'energia, adesso eseguo.

Completa l'output del comando nmcli facendo scrollare il pager (premendo ripetutamente il tasto [Spazio] o [Invio])

[OMBRA_Linux]

Infatti per questo avedo chiesto di dare questi comandi.

Codice: Seleziona tutto

lspci | grep -i wireless
lsusb | grep -i wireless

Allora a questo punto da Terminale lancia

Codice: Seleziona tutto

sudo iwconfig wlp2s0 power off

Se non dovesse funzionare lo riattivi con:

Codice: Seleziona tutto

sudo iwconfig wlp2s0 power on

E vedi come si comporta.
