Re: [CentOS] where to find wifi driver
which wifi adapter does centos 7.4 support? Could Centos give a list of those supported wifi adapters? Thanks!

For these Realtek drivers to be properly supported on RHEL (and CentOS), Realtek need to perform RHEL versioning checks (RHEL_MAJOR and RHEL_MINOR) in addition to their kernel versioning checks. My advice - if Realtek isn't prepared to support the device on RHEL (or CentOS), purchase an adapter that is natively supported. Yeah, sorry, I wasn't volunteering you to support this, but rather suggesting to the original poster that they might have better luck building it against an elrepo kernel than a CentOS kernel. No problem, and you are absolutely spot on that these drivers will be far easier to build against a vanilla kernel than a heavily backported RHEL/CentOS distro kernel. Still, if it were me, for the sake of $20 I'd rather go buy something that's natively supported out of the box than spend the next 5-10 years constantly wrestling with unsupported code. I appreciate all the time and effort ELrepo puts into providing packages. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Looking at the source code, it seems to provide some version of realtek driver. Since you run CentOS 7.4 it may be a good time to upgrade to current 7.6 release and see if it already supports your device.

Re: [CentOS] where to find wifi driver
Hi, I use the wifi adaptor, Edimax AC1200, and its driver can be downloaded from 'http://www.edimax.com.tw/edimax/download/download/data/edimax/tw/download/for_home/wireless_adapters/wireless_adapters_ac1200_dual-band/ew-7822ulc'. I fail to compile its GPL Source Code on CentOS 7.4. Where to get its rpm drivers, or how to compile its GPL Source Code?
