CentOS 6.6 WiFi problem - not connect

[Remsey]

Hey,

I'm newbie in CentOS. I have problem, beacause I haven't wifi.

Code: Select all

# /sbin/lspci | grep Wireless

03:00.0 Network controller: Intel Corporation Wireless 7265 (rev 59)

Code: Select all

# /sbin/lspci -n | grep 03:00.0

03:00.0 0280: 8086:095a (rev 59)

What I have to do in next step ?

A double grep for the Vendor:Device ID pairing (8086:095a) in the system's modules.alias file tells me that the iwlwifi driver is appropriate for your device --

Checking what firmware would be appropriate for the iwlwifi driver shows me --

So I would suggest that you check you have (at least) the kernel-firmware package installed. It probably wouldn't hurt to also insure that the other five firmware packages are also installed.

Now that you know the correct driver and the corresponding firmware for the driver, I'll suggest that you now take a look at the CentOS wiki page on Enabling NetworkManager.
