Come eseguire il debug di disconnessioni Wi-Fi ripetute in Arch Linux?

Dopo aver provato a lungo per ottenere una connessione wireless , ora sono in grado di ottenerne una estremamente abbozzata (come in pochi secondi di accesso effettivo a Internet ogni pochi minuti). In esecuzione wpa_supplicant -d -i wlp0s29f7u5 -c wifi.conf -Dwextin un VT e while ! yes | pacman -Syu; do :; donein un altro, dopo alcuni minuti non è ancora terminato, ma di tanto in tanto riesce a scaricare alcuni file.

iw dev wlp0s29f7u5 link sulla macchina Arch riporta una potenza del segnale di circa -40 dB, che è molto peggio del vicino laptop Ubuntu a -70 dB.

Uscita di connessione:

Il progresso di solito si ferma sulla EAPOL: disable timer ticklinea per alcuni secondi prima di continuare.

Qualche idea su cosa possa essere sbagliato? L'output è per lo più greco per me.

Devo fare qualcos'altro in background, come il rinnovo del contratto di locazione DHCP, quando viene stabilita la connessione per utilizzarlo il prima possibile?

E infine, -40 dB è considerato una qualità di collegamento "sopportabile"?

Ci sono un certo numero di cose strane che succedono qui:

Che cos'è una "risposta di sonda e sonda corrotta" e come posso ripararla?
Perché pensa che io sia in Polonia quando sono nel Regno Unito?
Perché i primi tre tentativi di connessione scadono sempre mentre il quarto ha esito positivo?

Che controller wifi è? Che macchina è? Potresti incollare l'output di lspci?

— mtahmed,

Va bene, penso che il problema sia il controller wifi. Quale sistema operativo stai usando? È archlinux?

— mtahmed,

Va bene, per quanto ne so, il problema è con i driver rtl8192c *. Prova a installare il dkms-rtl8192cupacchetto da AUR e riavvia e prova. Fammi sapere se funziona. A proposito, quale macchina stai usando? Un computer portatile?

— mtahmed,

È una macchina desktop, ma perché mai farebbe la differenza?

Perché alcune combinazioni hardware di rtl8192 non funzionano. Hai provato l' dkms-rtl8192cuautista?

— mtahmed,

Il problema sono le impostazioni di wpa_supplicant; Il primo -Dwext è vecchio. usare il secondo -Dnl80211 ; non aggiungere altro che net.lo e net.wlp0s29f7u5 al tuo script iniziale e aggiungerli all'avvio per caricarli. terzo; rimuovere qualcosa come NetworkManager o Wicd quarto; Pulisci il tuo file di rete e config_wlp0s29f7u5 = "dhcp". questo sarà utile se usi dhcp sulla tua connessione WIFI. anche nel tuo terminale con accesso super user digitare dhcpcd . solo per divertimento; può risolverti molto dolore

controlla anche il tuo kernel per il supporto Dnl80211 e anche il modulo della tua scheda wifi

Ciao @ r004, e benvenuto su USE. È generalmente considerata buona prassi modificare le proprie risposte anziché aggiungere commenti se si dispone di ulteriori informazioni. Inoltre, puoi formattare il testo come codice usando i backtick.
