These days it seems that the entire Internet is at a party at https://github.com, howsoever I guess you can ask the Fedora custodians for the Fedora part. Here are a few references about Realtek RTL8712 USB device support: - Realtek 802.11n drivers http://linuxwireless.org/en/users/Drivers/rtl819x https://wireless.wiki.kernel.org/en/users/drivers/rtl819x - "staging: refresh TODO for rtl8712" https://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/commit/drivers/staging/rtl8712/TODO?id=586add48d - "Re: r92su: status and will it be merged anytime soon?" https://marc.info/?l=linux-wireless&m=138358275410975 - Jes Sorensen _at_ redhat.com talk about possible support for Realtek RTL8712 USB device by RTL8XXXu USB mac80211 Wireless LAN Driver https://www.mail-archive.com/linux-kernel@xxxxxxxxxxxxxxx/msg1193475.html "For the rtl8712 device, rtl8192su?, then potentially that could be added to rtl8xxxu as well, but it's not a top priority on my list right now." More on the topic you can inquire at: http://vger.kernel.org/vger-lists.html#linux-wireless BTW, do you need directions on how to manage r92su.ko with the multitude of kernels? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
