13.10intel-wirelesswireless
I upgraded yesterday from ubuntu 13.04 to ubuntu 13.10 and now my wifi connection is incredibly slow.
ping google.com
takes upto 270 ms with 46% packet loss
edit: It appears that this issue is intermittent. However my other laptop on the same network was working at normal speed throughout which should rule out my connection.
for me the following worked in our company network with proxy:
cd /etc/apt
mv ./apt.conf ./apt.conf.bak
this is to force the system to use the new file we create now.
cd ./etc/apt/apt.conf.d
create new file "95proxies" and add there the content of the apt.conf file Example:
Acquire::http::Proxy “http://proxy_url:proxy_port/”;
Acquire::ftp::Proxy “http://proxy_url:proxy_port/”;
now the system use the 95proxies file
Try
sudo apt-get update
this should work now
Do:
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
Go into network manager and change your wireless settings to match the screenshots.
Go into your router and change 802.11bgn to 802.11bg then save the settings and reboot router and computer.
Lets modify this file: sudo /etc/modprobe.d/iwlwifi.conf change
options iwlwifi 11n_disable=1
To:
options iwlwifi 11n_disable=1 iwlwifi bt_coex_active=0
