[SOLVED] Intel Centrino Wireless-N 1030 not working in CentOS 7

lahfordie · 08-10-2016, 12:02 AM

Ever since installing CentOS, my wireless card hasn't connected to the network. (It works fine in Fedora and Ubuntu.) My wired interface has no issues.

I've re-downloaded the drivers from Intel and copied them to /lib/firmware, removed and reloaded them multiple times, and taken down and up network.service and NetworkManager.service in every combination. I've tried static and DHCP configurations. So far, nothing has gotten my wireless interface to work. So I turn to you for help.

Code:

[root@localhost network-scripts]# lspci | grep -i wireless
03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] (rev 34)

Code:

[root@localhost network-scripts]# lsmod | grep iwl

I don't run CentOS 7 so take my post with a grain of salt. I figure Ubuntu and Fedora see and make your wireless work because they use a newer kernel than CentOS 7.

Code:

uname -a

should clear some things up I think.

Just maybe a way out for you

Thanks for the suggestion. Unfortunately it didn't help. I upgraded to the newest kernel version on CentOS, then installed the proper iwlwifi versions for the 4.7 kernel from Intel. Still nothing. Same error:

Code:

[root@localhost network-scripts]# ./ifup ifcfg-ATTNpQ6FPi 
Error: Connection activation failed: No suitable device found for this connection.

Anyone have ideas?

It's fixed. The key was this, from the original post:

Code:

[root@localhost network-scripts]# nmcli d
DEVICE      TYPE      STATE      CONNECTION 
virbr0      bridge    connected  virbr0     
p5p1        ethernet  connected  p5p1       
lo          loopback  unmanaged  --         
virbr0-nic  tap       unmanaged  --         
wlp3s0      wifi      unmanaged  --         
[root@localhost network-scripts]# ip link show wlp3s0
7: wlp3s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN mode DEFAULT qlen 1000
    link/ether 58:91:cf:0f:d8:cc brd ff:ff:ff:ff:ff:ff

Specifically, "wlp3s0 wifi unmanaged --". I yum-installed the package "NetworkManager-wifi" and the problem disappeared. How I would've fixed this without NetworkManager (which shouldn't be necessary), I have no idea.

EDIT FOR CLARITY: I already had NetworkManager, but not NetworkManager-wifi.
