@suvasis What hardware do you have connected to your VOXL2? 

What do you see with `ifconfig` and `lsusb`?

What do you mean by internet is working? Internet on VOXL2? Or your network in general?

i meant general home internet is working ok.

I disconnected and reconnected the voxl2, it started working
wlan0 shows up now.

thanks.

seeing similar issues with wlan0, connected alfa wifi adapter and seeing under usb-devices but the driver is not attached to it.  Drivers are in /lib/modules/4.19.125/kernel/drivers/net/wireless/88XXau.ko

@JustinDev23 out of curiosity are you rebuilding the kernel?  I myself saw this recently when I had a custom kernel, and wondering if that's the path you're down currently.

@modaltb, thanks for the follow up.  it ended up being a driver issue. I am not doing any kernel changes.

I am using the Sentinel and it was not purchased with the wifi module or cabling. I have an assortment of the wifi usb adapters, using one of the older ones (AWUS036NHV) worked.
