Re: Wireless network card not detected after hibernate

Hi,

Check if knetworkconf still exist or install it:
sudo apt-get install knetworkconf

Try maybe the followed if you are sure it allready did work.

First login at Bash Konsole and type:

If you want to ask up your networking parameters, type:
ifconfig (simple using diagnostic)
ifconfig - a (more advanced)

I think you will need to follow eth0

Annyway you can always start with a ping to your own network card: Type following to ping your own network card:
ping 127.0.0.1

Now you will get something like this:
PING 127.0.0.1 (127.0.0.1) 56(84) bytes of data.
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.025 ms
64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.025 ms
64 bytes from 127.0.0.1: icmp_seq=3 ttl=64 time=0.025 ms

You stop the ping with CTRL+C button. If you got this, then you have allready some live at you network card. Otherwise you should check the drivers for your network card!!

So if you did have live at network card, try below commando's:
sudo /etc/init.d/networking stop (STOP NETWORK)
sudo /etc/init.d/networking start (START NETWORK)

there is also an option who gives you a force-reload. If you want to see al the options type:
sudo /etc/init.d/networking -?

Note: When you are using a wireless router, be sure you have dhcp enabled and the router is sending out his SSID & be sure your firewall is disabled. This is only needed when you have network troubles.... Also be sure, not 2 computers are using the same IP!

How to check if ufw is running, just type:
sudo ufw status

When it is running, just disable it with the command:
sudo ufw stop

To re-enabling it, just type:
sudo ufw start

When it stills not work, you can try followed:
sudo kate /etc/network/interfaces

You will probally see something like this:
auto lo
iface lo inet loopback

Try followed rules to add:
auto eth0
iface eth0 inet static
address 192.168.1.30 (THIS IS JUST AN EXAMPLE IP)
netmask 255.255.255.0
gateway 192.168.1.1
broadcast 192.168.1.255

WARNING: The IP I use here above is a example! For a lot of routers is the gateway 192.168.1.1 but for some it can be 192.168.2.1 or another. If it is 192.168.2.1 then you needed to type:

auto eth0
iface eth0 inet static
address 192.168.2.30 (THIS IS AN EXAMPLE IP)
netmask 255.255.255.0
gateway 192.168.2.1
broadcast 192.168.2.255

It's always wise, that you take first a copy of the file you change, if something goes wrong, you can put always back the original file

Where I did typei "THIS is an example IP" means there you can use an IP adress from:
192.168.x.2 to until 192.168.x.254
You just need to be sure there is not an other pc at your network who is using the same IP!!!!!

After that manual filling in, you need to check also this:

kate /etc/resolv.conf

this will give you the followed result if you have a router with gateway 192.168.1.1
# Generated by NetworkManager
domain home
search home
nameserver 192.168.1.1 (==>NEED TO BE THE SAME AS YOUR ROUTER GATEWAY)

There is also some info on the internet, that you if you have troubles, first goes with an other computer at the internet to the site: http://packages.ubuntu.com/fr/hardy/kde/knetworkconf

This should be the kde3.5 network configuration. KDE4 looks like a part of it

Download the debian file, and put it somewhere at your Kubuntu harddisk and try the following command:

sudo dpkg -i knetworkconf_3.5.9-0ubuntu5_i386.deb

After that, you should be able to access the network config GUI by right clicking the KnetworkManager icon in the panel, and selecting ‘manual configuration’. Or you can work with dhcp

For that last command you need to stand at the same location where you did copy it to!

Hopely I could help you with those network trouble

but be sure you network card is installed in the first place!
