How to setup wi-fi without ethernet access.

Post by traycaa » 2020/10/17 06:06:15

Hi guys,

So i'm in a bit of a pickle here. I have centos installed onto a laptop which can't connect to ethernet, so I can't easily install the appropriate drivers for wifi.

I understand that I have to install the packages manually from usb.

I found that installing elrepo will help me to aquire the firmware I need: http://elrepo.org/tiki/HomePage

I managed to install elrepo, but now I need to install the right package. The package I think I need is "rtlwifi-firmware", however I don't know which part of elrepo I need to install it in.

I have to figure out how to manually install the correct driver so I can finally get internet on centos and start to properly install packages using the internet.

The wifi in my laptop is a realtek wireless 8821ce , so if anyone can guide me step by step on how to correctly install and set this all up it would be greatly appreciated.

And of course, I am a complete noob to linux so pls help :P

Take a step back and post the output from lspci -nn | grep -iE "net|wireless"
CentOS 6 will die in November 2020 - migrate sooner rather than later!

Doesn't seem to be supported by anything in CentOS 8 so your best bet is to google ELRepo and raise a ticket on their bugtracker to request that they build a kmod package for it. The call that an RFE (Request For Enhancement) ticket.
