Tenda U3 wireless card I use, many of the problems encountered when installing the driver, was ultimately successful after kernel upgrade
Step One: Download driver files
that you can download to your card according to the manufacturer's official website
here to write kernel 2.6.24 support ~ 4.17, but my 3.10 CentOS is also not installed successfully
Step two: Enable ELRepo library
can be used ELRepo warehouse upgrade the kernel
boot command as follows:
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm
Step 3: Install the new kernel module compile the required documents
yum --disablerepo="*" --enablerepo="elrepo-kernel" install kernel-lt* kernel-devel kernel-headers
yum install gcc
Step four: reboot and remove the old kernel
First, edit / etc / default / grub file
vim /etc/default/grub
GRUB_DEFAULT = 0 modified to
generate grub configuration file, and restart the
grub2-mkconfig -o /boot/grub2/grub.cfg
shutdown -r now
Restart when selecting a new interface in the system kernel boot selection
Viewing the kernel:
rpm -qa | grep kernel
Delete the old kernel
yum remove kernel-3......
Step five: Install the driver file
you downloaded earlier extract the driver files, enter the directory
execute install.sh file
./install.sh
May be asked to enter the root password during
installation is now complete drive
