WIFI DONGLE with 5GHz AP support?

Hi,

after reading tons of information, I still can't understand if there is a WIFI-USB dongle with 5ghz which supports AP mode and works with LEDE/Openwrt without compiling drivers?
If it is, would you mind to help me with a model name?

My configuration:
LEDE_RELEASE="OpenWrt SNAPSHOT r6514-ed369e0"
LEDE_ARCH="x86_64"

148f:5572 Ralink Technology, Corp. RT5572 Wireless Adapter

software interface modes (can always be added):
		 * AP/VLAN
		 * monitor
	valid interface combinations:
		 * #{ managed } <= 1, #{ AP, P2P-client, P2P-GO } <= 1, #{ P2P-device } <= 1,
		   total <= 3, #channels <= 2

0e8d:7612 MediaTek Inc.

Thanks for answer.
Could you determine which kernel module is needed for this adapters?

Please use this as an example
https://wireless.wiki.kernel.org/en/users/drivers/mediatek

I mean "Which driver is used by those devices?"

mt76xx?

I just want to be sure that driver is compiled and available for x86_64

rt2800-usb
mt76x2u

Did you test mt76x2u with AP mode 5ghz?
As I know AP mode on mt76 driver was not working, is it fixed already?

Not tested, as I recall. I used it for Mesh only. I would recommend to use the normal AP instead of a dongle in a router.

my router is x86_64 laptop, and it has only 2.4ghz inside...

router != AP

I have a netgear a6210 running x86 on master with mt76 driver update from the source as the current mt76 driver on OpenWrt has not been updated, it support ac 5GHz on AP and STA

Can you elaborate on how you updated the driver from the source? Did you get the driver source from https://github.com/torvalds/linux/tree/master/drivers/net/wireless/mediatek/mt76 ?

From the OpenWrt mt76 source https://github.com/openwrt/mt76 edit the mt76 Makefile.
If you look at the OpenWrt mt76 Makefile history you can see a lot of examples how the driver has been updated https://github.com/openwrt/openwrt/tree/master/package/kernel/mt76
As example the one I using now https://github.com/1Jeff1/openwrt/commit/59bc22c57263c39978994e4fec00f5d973a53bb1

@jeff1

excuse to bring up this "old" topic again, but ...

has this "fix"/update been included into OpenWRT 19.x? Or ist it still neccessary to update the source and build the firmware by yourself?

The Makefile diff you pinted to pull the source from PKG_SOURCE_URL:=https://github.com/1Jeff1/mt76.git
is that still valid?

Or is all this obsolete by now and the MT7621u chips are alredy supported in AP mode by OpenWRT (19.x or master)?
