Hello guys:
I built an openwrt box, using an x86 64 bit processor, and I bought a rtl8812ae wireless card. However I noticed there is no driver for this chip in the x86 Chaos Calmer RC2.

I know there is a driver for this chip on the https://github.com/openwrt/bcm63xx-next … /rtl8821ae code repository, and for sure this chipset is supported on the vanilla x86 kernel.

Any help on how to create/add this package. I tried to follow this but I did not work well.
http://wiki.openwrt.org/doc/devel/packages

Thanks in advance.

Hi

a of commit 0c81733 the driver is already in vanilla kernel, around v3.17 I think.

You need only to modify the Makefile for building the kernel modules in openwrt

I am working to get this done, however I managed to create an empty package, and some how it seems that ALL the packages with source on SourceForge are failing (did SF change its url processing scheme???), I will post when I have more news or I am about to quit

News:
Managed to add driver via mac80211. yeah yeah

I still need to deploy my image and see if it really works.

Btw, how can I submit code and/or have a code review for this

Ran into this :'(

Box gets zombie after that

For submitting patches read this

Did you load/append the needed firmware files ??

Yes, I did appended the firmware. It seems the card works fine on client mode, but things go haywire with hostapd. It seems this is kinda common in RTL wifi cards tho ... (https://github.com/jekader/hostapd-rtl) (https://bugzilla.redhat.com/show_bug.cgi?id=797709)

Looks like some NULL Pointer dereference here.
Is this only in AP mode ??

To my knowledge AP will work, but can't test this without ripping the card out of my testrouter

Yes, it is only on AP mode... it seems I need a patched version of hostapd... or patch the driver (that scares me...)
