Buonasera a tutti, da ieri mi capita che sul mio notebook con Ubuntu 18.04, all'improvviso di si toglie il wifi e non trova più nessuna rete. Tutto questo fino al riavvio del pc, che dopo un pò però si ripresenta il problema. Qualcuno sa che problema potrebbe essere e come risolverlo? Ringrazio anticipatamente:)

Sempre da terminale

Codice: 
uname -r

Vediamo se corrisponde a quanto ho visto

Linux 5.3.0-46-generic uhci_hcd

Al limite proverei a farlo partire con il kernel 5.3.0-45, che vedo presente nel primo comando che hai eseguito

Vediamo se così ti da lo stesso problema.

Usi il 2.4 GHz o il 5.8 GHz?
Hai provato con una o con l'altra?

Allora non sono esperto di questa cosa, dovrebbe usare la 2.4ghz, ma non saprei come controllare e nel caso come cambiare

Sembra che la qualità del segnale sia un po' schifosa!

Eppure per quel poco che il wifi ha funzionato oggi, il pc lo avevo nella stessa stanza del router..

Per curiosità perchè hai cancellato ESSID e access point? MIca ho reso pubblico qualche dato sensibile della mia connessione? nel dubbio li ho cancellati
 
Fissazioni. :laughing7:

Ma adesso, ogni quanto tempo perdi il segnale?

Se ti allontani, a che distanza (metri) dal router, muri spessi?
Clicca per espandere...

10/15 metri al massimo. In ogni caso non lo ha mai fatto prima, quindi non è un problema di distanza, è proprio un problema del pc..

Spiego ancora meglio il problema: quando accendo il pc tutto ok il wifi è attivo, funzionante, e rileva anche le reti wifi dei vicini di casa. Quando all'improvviso smette di funzionare, smette di rilevare anche tutte le altre reti dei vicini, è come se il pc fosse sprovvisto di wifi... Poi quando riavvio torna tutto regolare per qualche minuto, dipende da dove mi metto con il pc, se mi allontano dura di meno, se sto nella stanza del router dura qualche minuto di più, ma comunque smette di funzionare lo stesso.

Proverei far girare il kernel precedente, che hai già in memoria

e vedi se ti fa lo stesso problema
