(info) RTL8832CU compatibility

[aquilarubra]

I have a new RTL8832CU (https://es.aliexpress.com/item/1005005544770386.html?spm=a2g0o.productlist.main.1.78ff96c6qceFKn&algo_pvid=9ee2eb8d-9883-4709-90f5-0dc6d98c40da&algo_exp_id=9ee2eb8d-9883-4709-90f5-0dc6d98c40da-0&pdp_npi=3%40dis%21EUR%2161.26%2130.62%21%21%21%21%21%402145277316844042289821012d07b5%2112000033481930568%21sea%21IT%211918944861&curPageLogUid=OMcZ7AW58cDB)

It's a very affordable tri band usb wifi card. I don't know if this driver could support it, but I am available to test. I am on Arch Linux, kernel 6.3.2.

Once inserted, it gives:
0bda:1a2b Realtek Semiconductor Corp. RTL8188GU 802.11n WLAN Adapter (Driver CDROM Mode)

After an eject cdrom:
0bda:c832 Realtek Semiconductor Corp. 802.11ax WLAN Adapter

Thank you, I saw the Comfast. However, it is not tri band.
Practically, only Netgear A8000 is tri band and compatible with Linux, with availability on the market. And it costs over three times more. Hopefully, the RTL8832CU will be considered some day. I will try to ask in the linux-wireless list.

I saw the Comfast. However, it is not tri band.

Yes it is. Numerous Linux users have reported that it is tri-band. I have the CF-951AX which uses the same chipset. It is tri-band. Mediatek has not made a WiFi 6 chipset that is NOT tri-band. The Windows driver may be limited to AX1800 but the Linux driver supports the full tri-band capability.

Some sellers of adapters with the mt7921au chipset are only advertising as AX1800 but we really do not know why other than when they started production Windows did not support 6 GHz.

Practically, only Netgear A8000 is tri band and compatible with Linux, with availability on the market.

Okay, so, you did not read the links I provided. I'm trying to help you.

The ALFA AXML also advertises as AXE3000 tri-band. Both the ALFA and Netgear A8000 use the same exact chipset and use the same driver as the Comfast CF-953AX.

I will try to ask in the linux-wireless list.

You may not get an answer at linux-wireless as that is not what that list is for.

Thank you again. Now I understand better and found further references.

Look at the adapter in the link below. It is more affordable and it is Plug and Play. The driver was in the Linux kernel last year before we could buy adapters.

Unfortunately that link now goes to the version 2 of the adapter which uses a Realtek chip

Hi @nikkopt

Thanks for the info. I deleted that msg with the link.

To always get the current recommendations, see the Plug and Play List. It is menu item 2 on the Main Menu:

There are currently 6 WiFi 6 adapters in the mt7921au section but there are many adapters in the Plug and Play List depending on what you need.
