Wi-Fi connection problem on Ubuntu 14.04
I have installed Ubuntu 14.04 (Thusty Tahr) and Wi-Fi scans the networks and connects correctly, but Mozilla Firefox or Google Chrome can’t open websites. It works with cable connection trouble-free.
I looked for a solution long time on the Internet. Then I found that there is a bug in Ubuntu Network Manager. Because of this bug Ubuntu Network Manager takes Bit Rate=1 Mb/s for wlan0.
iwconfig wlan0 rate 54M
Make this automatically for every system start:
sudo gedit /etc/rc.local # add the following line before exit 0 line, save and exit iwconfig wlan0 rate 54M
