Lightbulb NetworkManager applet won't connect to Internet


hi,
i have a 'Intel Corporation WiFi Link 5100' netcard, formly at start up the system wrote iwlwifi-5000-1, iwlwifi-5000-2, iwlwifi-5000-3, iwlwifi-5000-4, iwlwifi-5000-5 is missing. I downloaded them and put them in /lib/firmware, no the error message disappeared and i'm connected to my router, but i only have internet with ethernet, although signal strenght is 97%. What can be wrong? How can I solve this?
thank you!

You give your distribution as Slackware, without a statement of the version in use.

You should not have needed to download the firmware for your wifi device, as it would have been included in the default full install of Slackware. Did you do some sort of minimal install?

Were you formerly using the internet only via the ethernet interface using a configuration in /etc/rc.d/rc.inet1.conf?
If so, then revert to a clean /etc/rc.d/rc.inet1.conf. http://www.linuxquestions.org/questi...9/#post5236776

Rather than copying the firmware files manually, add the "contrib" & "non-free" components to your repository lines in /etc/apt/sources.list and then run:
Code:
# apt-get update
# apt-get install firmware-iwlwifi
https://wiki.debian.org/SourcesList#Component

If it still doesn't work, post the output of:
Code:
ip r
dmesg|grep -i iwl
lspci -knn|grep -iA2 net

Not at all -- see this example:
https://wiki.debian.org/SourcesList#...8_.22Jessie.22

You should add "contrib" & "non-free" (without the quotation marks) immediately after the word "main" (on the same line).

Also, I don't think "Debian8.0" is a release version understood by APT -- replace that with "jessie" so that it looks like the example given above, ie:
Code:
deb http://ftp.de.debian.org/debian jessie main contrib non-free
deb-src http://ftp.de.debian.org/debian jessie main contrib non-free

deb http://ftp.de.debian.org/debian jessie-updates main contrib non-free
deb-src http://ftp.de.debian.org/debian jessie-updates main contrib non-free

deb http://security.debian.org/ jessie/updates main
deb-src http://security.debian.org/ jessie/updates main
Then use:
Code:
# apt-get update
# apt-get install firmware-iwlwifi
At any rate, your interface is already up & running (you should still install the firmware from the repositories so that is can be updated); I think the problem is that NetworkManager will always use the ethernet connection if the cable is connected.

Try either unplugging the cable or explicitly disabling the wired connection from the control panel.

thank you,
now it works better but only for some seconds, and if i ping for example linux.org or google.com, it will know the IP address of the server, but it says 'destination host unreachable'

From what I see here, you don't have a default gateway configured.

Also, I see that both the wireless and the ethernet have the same IP address '192.168.0.2'. This can cause you some issues if you are not using something like link aggregation or similar solutions. You should check that.

Try to set up the default gateway. For a temporary solution you could try this:

Code:
ip route add default via 192.168.0.1 dev wlan0
I assume that you gateway has '192.168.0.1' as the LAN IP address, change it if you need to.

If this works, you should change your networking configuration and add the default gateway.
