I'm new in Ubuntu and just downloaded Ubuntu Gnome 14.04 LTS. The PC is working fine. The problem is that the internet is kinda slow. It loads the pages but it takes forever. Seen an HD quality video on YouTube is impossible. I've tried what it says here: http://pkill-9.com/stabilizing-atheros-ar9485-ath9k-connection-linux-wheezy/ However, where it says to write
cd /etc/network # go to network interfaces
sudo cp interfaces interfaces.org # make a backup copy
sudo nano interfaces
I get:
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
And in 'HOKEY POKEY PART 2!' my PC shows the same message as in the step 5.
If anyone knows how to solve this problem I would really appreciate.
After using iwlist scan, this is what it shows:
Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s 9 Mb/s; 12 Mb/s; 18 Mb/s Bit Rates:24 Mb/s; 36 Mb/s; 48 Mb/s; 54 Mb/s IE: IEEE 802.11i/WPA2 Version 1 Group Cipher : TKIP Pairwise Ciphers (1) : CCMP Authentication Suites (1) : PSK
PS: I have dual-boot with windows 8 x64 and the internet works perfectly.
iwlist scan
in terminal to check your wifi settings, you want to see WPA2 Version 1 and CCMP, absolutely no TKIP
