I continuously have a problem with browsing internet on Dell laptop through WI-FI.
The problem occurs suddenly, Firefox and Chrome refuse to find a resource, the interesting part is the connection is ok, skype works, pings is ok.
Inversigation:
- Restarting browsers doesn't help.
- Disabling/Enabling WI-FI doesn't help.
- Disabling/Enabling networking doesn't help.
- Retrive resources by IP doesn't help.
- Lowering MTU to 1400 doesn't help.
- Downgrade to Ubuntu 12.04 LTS doesn't help.
- Logout/Login doesn't help.
Temporary Solution:
Only full restart helps. (Not logout/login, but switch off and switch on)
Terrible consequences:
This laptop belongs to my girlfriend, and she threatens me, and demands to install Windows. I cannot stay any longer. So far I don't know what is the solution. Please help me to solve it, I will provide you with any needed infomation, log, etc.
