USB Wifi not found on Centos 7 Guest

Post by sherbs » 2019/03/30 21:52:51

Hi,

I'm trying to use a wifi dongle ASUS USB-AC54 Nano as a wireless connection on a Centos7 guest on a KVM virtualisation (host is a Centos 7).

All systems are up-to-date (sudo yum update).

lsusb on the guest finds the adapter:
# lsusb
Bus 001 Device 004: ID 13fe:4100 Kingston Technology Company Inc. Flash drive
Bus 001 Device 003: ID 0b05:184c ASUSTek Computer, Inc.
Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

However, network manager odes not. "No Wi-Fi Adapter Found".

(Wired) network connections on guest are fine, however I need to use Wi-Fi for testing purposes.

# ifconfig

Any ideas?

Google says that adapter has an MT7610u chipset. There is a nice shiny new package in the ELRepo (third party yum repo) that supports some of those Mediatek chipsets but I do not think it has support for yours. You could try it but I don't hold out much hope of it working as it doesn't list your USB ids as supported. For vendor id 0x0b05 it only contains

modalias(usb:v0B05p17D3d*dc*dsc*dp*ic*isc*ip*in*)

Thanks, just found a typo, it's the USB-AC53 (not 54) with the rtl8822bu chipset... unfortunatly did not find this on the elrepo. Found some on github, however, I did not find a package that compiled successfully, they all seam to be prepared for debian, not centos.

Alternativley I could use a Netgear AC1200 Wifi USB Adapter (A6150) with the RTL8812BU chipset. not found on elrepo either and no successful compilations...

Suggestions? Or should I try to get an older WiFi USB adapter that has better support on Centos?
