Linksys WUSB6300 shows as wired ethernet on CentOS 7 1611 Final (kernel 3.10.0-514.el7.x86_64)

[Spork-Schivago]

Hello,

I'm having issues with this module. I'm running a fresh install of CentOS 7 1611 Final and I compile the module, insert it into the kernel using insmod, insert the USB wireless NIC (a Linksys WUSB6300 with the RealTek 8812AU chipset), and the device appears in Gnome as a wired ethernet card, not a wireless NIC.

Any suggestions on how to fix this? I'm not sure if it's something with the module or CentOS 7. But from reading stuff on the internet, it seems a lot of people have this issue when they're using the module with the RealTek 8812AU chipset.

I'm running the kernel that on the installation media, 3.10.0-514.el7.x86_64. Unfortunately, at this point, I have no way of hooking the machine to update it until I get the wireless NIC working, so I don't know if there's a newer kernel available or not.

I would be down for providing more information, if you need it, and I will test anything you want tested.

Thank you.

Same here, kernel 3.10.0-693.el7.x86_64.
Compiled from master.

Device is a ¨chinese¨(or not very well known) brand, shows up as RTL8812AU in lsusb (Bus 003 Device 007: ID 0bda:8812 Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac 2T2R DB WLAN Adapter).

After loading module, appears as a wired network in network manager. Here´s the correponding ip a line:
5: enp0s20u9: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000
link/ether e8:4e:06:4a:c5:ba brd ff:ff:ff:ff:ff:ff

Let me know if I can add any more info or logs.

I have both Centos 7 and Archlinux on the same computer. This problem seems to be Centos 7 specific, since I never have problem with Archlinux.

I tried to update the kernel in Centos 7 to 4.4 and even 4.19 but with no luck, so it's not related to kernel. I also tried 'lsusb' on both system, and found the device name is not shown in Centos 7.

CentOS: Bus 005 Device 002: ID 2357:0101
Arch: Bus 005 Device 002: ID 2357:0101 TP-Link RTL8812AU Archer T4U 802.11ac

And here is the output of 'lshw' for both system (the same)
