Salve a tutti, ho installato ubuntu 19.04 su un notebook Mediacom Smartbook edge2 14 ma il wifi funziona male. Non si connette quasi mai, ma quando lo fa va veramente molto lento. Potete darmi una mano?

non riesco a trovare il wifi

che vedi dal comando: inxi -n

p.s. qui caso simile... https://forum.ubuntu-it.org/viewtopic.php?f=9&t=631629 non ho ben chiaro la soluzione...

(26 Set, 17:42) sacarde sacarde's gravatar image

L' output del comando inxi -n:

Network:

  IF-ID-1: bnep0 state: unknown speed: N/A duplex: N/A

Dal comando lshw trovo questo:

e il suo modulo/driver: rtl8xxxu

che vedi dal comando:

systool -vm rtl8xxxu

la parte: Parameters

strano... non visualizza i parametri

che vedi da: modinfo rtl8xxxu

p.s. in alternativa si potrebbe creare il modulo rtl8723bu come dal mio link di sopra

Ho seguito la guida per l'installazione dei driver rtl8723du come spiegato nell'ultima guida postata. Ho dovuto aggiungere un comando della prima guida postata, cioè "echo blacklist rtl8xxxu | sudo tee -a" Ora funziona benissimo ma è come se vedessi 2 schede wifi che posso usare indistintamente una dall'altra, ma a parte questo IL PROBLEMA È RISOLTO.

Grazie di tutto
