How to enable wifi in centos 7 on ASUS X550L?

Question

ASUS

There is an ASUS X550L laptop on which WiFi worked while the installer was running, but after the installation was completed it stopped and is not visible in the list of available connection methods.

uname -a
Linux egor 3.10.0-229.4.2.el7.x86_64 #1 SMP Wed May 13 10:06:09 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

lspci | grep -i network
03:00.0 Network controller: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe

I tried to look for drivers on elrepo, but did not find it.
UPD:
I searched on elrepo here: elrepo.org/tiki/DeviceIDs at 1814:3290, there is no such thing.
Tried to compile the driver from here: www.mediatek.com/en/downloads/?sort=os , RT3290 PCIe, but got an error:

/home/epetrov/Загрузки/DPO_RT3290_LinuxSTA_V2600_20120508/os/linux/../../os/linux/rt_linux.c:1136:20: ошибка: incompatible types when assigning to type «int» from type «kuid_t»
   pOSFSInfo->fsuid = current_fsuid();
                    ^

   pOSFSInfo->fsgid = current_fsgid();

UPD2:
At the same time, there is such a conclusion:

grep -i 1814 /lib/modules/*/modules.alias | grep -i 3290
[sudo] password for epetrov: 
/lib/modules/3.10.0-229.4.2.el7.x86_64/modules.alias:alias pci:v00001814d00003290sv*sd*bc*sc*i* rt2800pci
/lib/modules/3.10.0-229.el7.x86_64/modules.alias:alias pci:v00001814d00003290sv*sd*bc*sc*i* rt2800pci

Does this mean that the drivers are still there? Why then they are not used and how to enable them?

Answer 1

# yum install net-tools
# ifconfig -a
# ifconfig wlan0 (your name may be different) up

Answer 2

And why did you decide that there is no driver? It's written

spci | grep -i network
03:00.0 Network controller: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe
