Hi, Is AP/VLAN mode supported by this driver? It's difficult to find out because not many people use that feature. Thanks

I am not familiar with this capability. Can you provide a link so that I can educate myself on this topic.

Regards.

OpenWRT can be used for this, if the driver supports AP/VLAN mode: https://openwrt.org/docs/guide-user/network/wifi/wireless.security.8021x#x_dynamic_vlans_on_an_openwrt_router Thanks.

Okay, I have a little better understanding now. I still don't have experience with it so take what I say as a best guess based on a little research. I concentrate my efforts on client and ap modes.

Of the 80211AC capable adapters that I have, the only one that is capable of AP/VLAN on Linux is the adapter based on the mt7612u chipset. None of the adapters based on Realtek chipsets are capable due to driver limitations. This is not a capability that is likely to happen out here in the user community. Realtek would need to add this capability.

Yep, that's what I thought the situation might be. Thanks for taking a look.

prbluebottle,

I was doing some work this morning with an adapter that uses the mt7612u chipset. Listed capabilities:

software interface modes:
     * AP/VLAN
     * monitor
valid interface combinations:
     * #{ IBSS } <= 1, #{ managed, AP, mesh point, P2P-client, P2P-GO } <= 2,
       total <= 2, #channels <= 1, STA/AP BI must match

That caught my eye so I thought I would pass this on to you. I'm not sure if that is what you are looking for. You can find links to adapters that use the mt7612u chipset here:

FYI: I am currently testing an adapter with the 7612u chipset on a RasPi4b with RasPi OS (32 bit)(kernel 5.10). The driver for this chipset is in-kernel and so far seems very solid. I have confirmed WPA-3 SAE support so far. I can post additional test results when available if you are interested.

Edit: My continued testing shows that USB3 support works and is solid, and AP mode (hostapd) is working very well with this adapter at 80211n, 300 Mb/s, 40 MHz channel width. I have tested 2g and 5g, both are solid. I will test additional capabilities as I have time.

Thanks for the info, might end up buying one of those.
