Wifi lento dopo con Centrino Wireless-N 1030 [Rainbow Peak]

4

Dopo l'aggiornamento da kubuntu 13.04 a 13.10 improvvisamente la mia connessione wifi è molto lenta. I tempi di ping variano da 200 a 1500 ms a www.google.nl.

Quando collego il cavo Ethernet, scendono a tempi normali come 8 o 9 ms. Qualcuno sta vivendo lo stesso problema o conosce una soluzione che posso provare? Durante il processo di aggiornamento alcune volte hanno chiesto se volevo conservare o sostituire un qualche tipo di file di configurazione. Non sono più sicuro di quale file fosse, ma forse questo ha qualcosa a che fare con esso. Prima dell'aggiornamento, la connessione cablata e wireless funzionava perfettamente.

fare:

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwldvm
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

Accedi al gestore di rete e modifica le tue impostazioni wireless in modo che corrispondano agli screenshot.

Accedi al router e modifica 802.11bgn in 802.11bg, quindi salva le impostazioni e riavvia il router e il computer.

Consente di modificare questo file:     sudo /etc/modprobe.d/iwlwifi.conf cambia

options iwlwifi 11n_disable=1

A:

options iwlwifi 11n_disable=1 iwlwifi bt_coex_active=0

Ho avuto lo stesso problema quando ho aggiornato alla 14.04. Ho provato tutto anche le risposte di questo post. Dopo un po 'ho pensato di provare a LM, il problema è sparito e la magia è nel pacchetto linux-firmware. LM usa la vecchia versione che è 1.127 mentre Ubuntu ora usa 1.127.7. Il modo più semplice per ripristinarlo in questa versione è: installare Synaptic, trovare questo pacchetto, fare clic su di esso per contrassegnarlo, premere Ctrl + E e modificare la sua versione. Applica le modifiche e risolvi i problemi.

Ho risolto questo problema eseguendo il downgrade della versione del mio kernel.
