Ho eseguito Ubuntu 14.04 utilizzando le build di sviluppo per oltre un mese senza problemi. Quindi ho aggiornato alla data di rilascio ufficiale e il problema è iniziato. Mi sono sentito frustrato e ho eseguito una nuova installazione e ho ancora lo stesso problema.
Posso connettermi alla mia rete wireless bene, ma la mia potenza e velocità di connessione sono molto sporadiche. Sembra oscillare da molto lento a normale molto rapidamente come un'onda. I risultati del ping di seguito con il mio router potrebbero illustrarlo.
Router che esegue il ping, da normale a basso carico:

MODIFICA:
Correlati:i programmi in esecuzione non vengono visualizzati nel pannello?Il mio laptop è un Toshiba Satellite S55-A5294.
Dopo aver aggiornato il mio kernel a 3.14.1 e 3.14.2 (attualmente in uso), il mio wireless è ora utilizzabile a volte (il che mi rende felice).
Perdo lo 0% dei pacchetti circa il 70% delle volte e dall'1 al 100% della perdita di pacchetti l'altro 30%.
La riconnessione alla mia rete wireless è l'unica soluzione che ho trovato finora, ma non sempre risolve il problema.

Non sono sicuro che questi registri siano un'indicazione della causa di questo problema o solo una notifica che si sta verificando.
Qualsiasi idea sarebbe molto apprezzata.
Risposta accettata:
Questo è un problema che ho riscontrato anche io. Per risolverlo è necessario aggiornare manualmente il kernel. Ho eseguito l'aggiornamento alla 3.14.1 personalmente.
Ecco una guida sull'aggiornamento manuale del kernel:come aggiornare il kernel all'ultima versione della linea principale senza alcun aggiornamento della distribuzione?
EDIT:Neanche me ne rendevo conto quando l'ho pubblicato, ma ho la tua stessa scheda wireless, quindi dovrebbe funzionare. Non posso garantire su nessun'altra carta.
