Hello,

I'm pretty noob with kubuntu so tell me what can i do to help you to resolve my issue.

Is this limited to http traffic, can you still reach this site which is https?
Have you tried different browser like Konqueror, Firefox and Chromium?

Does it affect other protocols like ftp, pop or imap mail or newsgroups?

If it is 'just' browsing what is stopped you could try deleting the cookies from the offending sites and try again.

HI ,
thx for your reply.
I using firefox as browser and i don't know with other one.
But when the problem appears all of http / https web site are not reachable.
I didn't try too but i tink that other protocol like pop ... have the same problem.

Yesturday i try with a wire directly connected to my box and no problems appears, so i think that the problem is only on wifi.

To make it simpler, when browsing no longer works, can you still ping say, google.com?

If you get nothing when you issue:
ping Google.com
then try
ping 8.8.8.8
If that responds then your DNS is fouled up.
Try restarting your network service:
sudo /etc/init.d/networking restart

Hello

So when my appeared when i launched the download a software in Muon.
I try some of your solution. And immediatly after the connection of a the ethernet wire i was able to go to the internet :

Here you can see my interfaces file :

auto lo
iface lo inet loopback


Heresome test :
ping ww.google.com : unknow host www.google.com
ping 8.8.8.8 : From 192.168.1.95 : icmp_seq=1 Destination Host Unreachable

And the commande : sudo /etc/init.d/networking restart doesn't change anything.
When i launch this command nothing was writen into the console.

Do you get wifi on any other device; cell phone, tablet, etc? If you have no other device, have a friend try to receive wifi in your home.

I'm not at home but in a friend house and he has no problem with him wifi (my girlfriend too) only in my laptop.

What does
lspci

As I said previously the problem appears after a simple download or launching a video on Youtube (when I ask too much internet)

Ah, the RTL8* wifi. My PC has a similar model RLT8188CE.

First, create the following file as root:
/etc/modprobe.d/rtl8723be.conf
then add the foilowing line:
options rtl8723be fwlps=0 ips=0

My .conf file has the following line in it:
options rtl8192ce ips=0 swlps=0 fwlps=0

They turn off link and FW power contral saves, which are on by default.
The two other possible settings are off by default.


The following solution only works for Trusty:

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms linux-firmware
