Best 5GHz USB Wifi Adapter to Work with OpenWrt

I need a 5GHz USB Wifi adapter to work with OpenWRT version "SNAPSHOT r8875-a28f6ab" or 18.06.1 to act as a client and connect to an outside Wifi network. I need something that is an easy setup and not having to compile drivers and such. Thanks!

I love you! :heart_eyes:

All those are not supported by mt76 per se, this is the currently supported list.

How does that work? If they use the same chipset shouldn't they work?

Not necessarily, https://github.com/openwrt/mt76/issues/200 as an example

Do you if TP Link Archer T4U V2 will work with the snapshot version r8875-a28f6ab? The device has RTL8812AU chipset and OpenWRT snapshot has kmod-rtl8812au-ct driver. This is the best adapter I found for the price, just hoping it will work!

The ASUS adapters should work. I think those are what upstream uses to test.

The Alfa adapter should also work. I have one but have not tested.

@diizzy I bought EDUP EP-AC1605 adapter https://www.aliexpress.com/item/EDUP-USB-3-0-Wireless-Wifi-Adapter-Dual-Band-2-4GHz-5GHz-1200Mbps-802-11AC-IEEE/32655418931.html?spm=a2g0s.9042311.0.0.d7534c4dRETXSE

Adapter seems working except Access Point mode.
I created Access Point via LuCi, however SSID is not seen by the client devices.

this is the settings I used in /etc/config/wireless

config wifi-device 'radio1'
        option type 'mac80211'
        option channel '36'
        option hwmode '11a'
        option path 'platform/1e1c0000.xhci/usb2/2-1/2-1.4/2-1.4:1.0'
        option htmode 'VHT80'

config wifi-iface 'default_radio1'
        option device 'radio1'
        option network 'lan'
        option ssid 'HotSpot_5ghz'
        option key '**********'
        option encryption 'psk2+ccmp'

Is the AP mode supoorted by driver? If yes, what am I doing wrong?

Hi, sorry but did you solve this problem?

No, the developer said MT76x2U driver doesn't support Access Point functionality for USB interface yet.
Client mode works fine.

Did you find any usb card with AP as substitute?

Personally, I would not use any USB wifi dongle to act as AP even if it supports MSSID, considering you need to squeeze all the traffic via the USB (I assumed we are talking about the USB version 2 on both router and dongle), which doesn't make sense, given a modest dual band device is so affordable nowadays.

As a client device, I am also skeptical. I used to deploy mass USB dongle for our company's machines without wire reach. The high failure rates are something you have to live with especially those bought in aliexpress or wish and of the higher TX rating. Be sure to buy a couple more and keep them aside for near future replacement if you insist.

I would personally use a low loss cable with a high gain antenna on the router when acting as a client.

No, I ordered MT7612E MiniPCIe card. My router is flexible, has two MiniPCIe slots

Please forgive me. Somehow, I read the topic mentioning USB.

Please tell me, what router it is?
