According to the man page for the [rtwn](https://www.freebsd.org/cgi/man.cgi?query=rtwn&sektion=4&manpath=freebsd-release-ports) driver, this card was supported, however the driver refused to attach.

When I finally sat down tonight to start on it, I found the fix surprisingly simple. Looking at the driver source code under /sys/dev/rtwn/pci/rtwn_pci_attach.h, I see an array containing the vendor id's and device id's for PCI devices: >> >> static const struct rtwn_pci_ident rtwn_pci_ident_table[] = { >> { 0x10ec, 0x8176, "Realtek RTL8188CE", RTWN_CHIP_RTL8192CE }, >> { 0, 0, NULL, RTWN_CHIP_MAX_PCI } >> }; >> >> I noticed the device id 0x8176 was different from my card, which was reported as 0x8178.

I'm also sure, there are other device id's that would need added to have full support, but after asking some other people, I was suggested to send an email to this address. >> >> Thanks, >> James Parsons >> _______________________________________________ >> freebsd-wireless@freebsd.org mailing list >> https://lists.freebsd.org/mailman/listinfo/freebsd-wireless >> To unsubscribe, send any mail to "freebsd-wireless-unsubscribe@freebsd.org"help
