RTL8185L installation WIFI not working

Post by thornydre » 2017/10/23 16:58:55

Hi everyone,

I just installed Centos7 and I want to get my WIFI working.

I have a PCI Express card RTL8185L from Realtek I guess but I can't find the driver on the official website. The only information that I have is the return of this command : /sbin/lspci | grep Ethernet

I get : Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8185 IEEE 802.11a/b/g Wireless LAN Controller (rev20)

Do you have any idea if I can get this working ?

Thanks

You missed the -nn switch off lspci. Try again with it.
The future appears to be RHEL or Debian. I think I'm going Debian.

With the command : /sbin/lspci -nn | grep Ethernet

I just have the same result with [10ec:8185] at the end

Yes, exactly, it's the 10ec:8185 that identifies the device uniquely and allows us to check if the device is supported by running e.g. grep -i 10ec /lib/modules/3.10.0-693.2.2.el7.x86_64/modules.* | grep -i 8185. If there was a driver then it would list it and tell you what module to load. That gives no output so there is no driver available.

Your next step is to take those vendor:device id numbers to the ELRepo website and see if they already have a kmod-X driver for it. If they don't then you could try raising an RFE on their ticket tracker and see if they will create one.

According to the device IDs [10ec:8185] CentOS-7 kernels do not have the driver for your device. I suggest you try installing ELRepo's kernel-ml. Once it is confirmed that kernel-ml works, you can keep using it, or submit a request to enable RTL8180 in the config of the centosplus kernel.

Thank you for your answer I'll try that, I found this on the ELRepo website, don't know if it can work : http://elrepo.org/tiki/kmod-compat-wire ... light=8185

But I just reboot on my Centos7 hardrive and I have an error on the grub :

Failed to open \EFI\BOOT\grubx64.efi - Not Found
Failed to load image \EFI\BOOT\grubx64.efi : Not Found
start_image() returned Not Found

So I'll try to install Centos again and try the driver above after that

Well I tried the link I posted before, and the last command won't work, the command :
depmod -a ; modprobe brcmsmac

And it returns this :
modprobe: ERROR: could not insert 'brcmsmac' : Operation not permitted

I don't even know of it is way to do install the driver or if I am totally wrong, maybe I should try to write a ticket on elrepo to get the driver ?

Sorry I really don't understand all the kernel -ml thing hehe

You can find the latest kernel-ml here:

http://elrepo.org/linux/kernel/el7/x86_64/RPMS/

For example, download kernel-ml-4.13.9-1.el7.elrepo.x86_64.rpm and install it by running:

Code: Select all

rpm -ivh kernel-ml-4.13.9-1.el7.elrepo.x86_64.rpm
then boot to that kernel.

Good hear. :)

Now, if you want to continue using kernel-ml, that is fine. If you want to go back to the CentOS kernel, you can try either:
(1) Ask ELRepo for a kmod-package for your device - http://elrepo.org/bugs/
or
(2) Ask CentOS to enable the driver in the CentOSPlus kernel - http://bugs.centos.org

Either way you can quote this forum thread when filing a request.
