Are you sure it is not an update or something else that is starting to run (like normally in Windows...) Check processor activity with System Monitor and test network speed (with a known speed test site) to confirm. Disconnect and reconnect and do speed test again to make sure it is a driver or configuration issue. Sorry, this is all I can help.

  • my wireless network speed is ok, I have tested all solutions in this page http://itsfoss.com/speed-up-slow-wifi-connection-ubuntu/ but nothing work for me, please you can tell me how to I can debug the wireless connection, or maybe I should try with ubuntu 14.04 or 15.04. – Ernesto De Leon Mar 09 '15 at 03:35
  • nobody can answer something? there are to many people with this issue and nobody can give one tip? that sad. – Ernesto De Leon Mar 14 '15 at 03:19
  • If the standard log with dmesg or /var/log/messages don't give extra information you need to delve deeper into the other log files. netstat can give you instant monitoring information. Are you connecting to a home network with possible windows authentication issues? - just a shot in the dark. – user130266 Mar 16 '15 at 05:33
