Centos 5 wireless problem SIOCSIFFLAGS: No such file or directory

0. Connect as a root user.

1. First of all determine which wireless card you have:

/sbin/lspci | grep Wireless

My output is :

02:00.0 Network controller: Intel Corporation PRO/Wireless5100 ANG…

1.Download firmware from here.(This is for 5100,5300 and 5350 (iwlang))

2. Install downloaded package:

rpm -Uvh iwl5000-firmware-8.24.2.12-1.elrepo.noarch.rpm

3. Reload iwlagn module

modprobe -r iwlagn;
modprobe iwlagn

4. Start wlan0

ifconfig wlan0 up

5. Enable Network Manager:

chkconfig NetworkManager on
service NetworkManager start

That’s all!

Open Suse 11.4 Wireless is connected(active) but there is no internet [SOLVED]

In this post, I am going to provide you by one of the solution which helped me…

I simply renamed resolv.conf file which is located in /etc:

:~> su
Password:

# cd /etc
# mv resolv.conf resolv111.conf

That’s it.

Let’s expalin a little bit more:

What is resolv.conf?

Resolv.conf is a resolver configuration file. This file defines which Doman Name Servers to use.

See the content of this file:

#cat resolv.conf

search domain.com site
nameserver 192.168.1.111
nameserver 192.168.1.143

Means-> when you type http://www.google.com It will go to the first DNS server 192.168.1.111 and ask what IP does this google.com corresponds. If this nameserver doesn’t know the answer, 192.168.1.143 will be next nameserver to be asked.

 

If you know the correct name servers just modify this file with correct entries(instead of renaming it).

But if it doesn’t work… Run the Network Settings, in Global Options tab, in the  IPv6 Protocol Settings section, uncheck the box Enable IPv6.
