Ho un problema con il Wi-Fi da quando ho installato Linux Ubuntu 19.10 cioè la mia connessione risulta lenta e compare un punto interrogativo sul simbolo della connesione Wi-Fi ma se io provo con altri dispositivi o con altri sistemi operativi sullo stesso computer (ho avuto Windows 7, Windows 8, Windows 10 e mai un problema con la scheda wireless). Ho provato anche con alcune soluzioni online con comandi sul terminale ma nulla. Ho anche disattivato a turni IPv4 e IPv6 ma nulla. Qualcuno può aiutarmi?

Sul router ho sia la connessione 2.4 GHz e sia la GHz però il pc non ha una scheda wireless che lo supporta il 5

si ho disabilitato l'IPv6

systool -vm ath9k

Module = "ath9k"

Attributes: coresize = "151552" initsize = "0" initstate = "live" refcnt = "0" srcversion = "EF1E6B00DBFECEEC2C25BDC" taint = "" uevent = <store method="" only="">

Parameters: blink = "0" bt_ant_diversity = "0" btcoex_enable = "0" led_active_high = "-1" nohwcrypt = "0" ps_enable = "0" use_chanctx = "0" use_msi = "0"

ma per il systool -vm iwlwifi mi da questo errore Error opening module iwlwifi

  • nohwcrypt non e' "1" (soluzione 1)

  • iwlwifi vuol dire che non viene caricato... che vedi da: lsmod

  • la scheda wireless e' pci o usb? la vedi da: "lspci" o da "lsusb" ?
