[Putting ASRock USB WiFi dongle in monitor mode]

I bought an ASRock USB WiFi dongle from HAK5 recently. I'm using on my XPS13 running Ubuntu 17.04.

When I plug it in and do an ifconfig it returns as wlx002522508b5d

If I then try and pit it in monitor mode using

sudo airmon-ng start wlx002522508b5d

The device then vanishes from the ifconfig list and I get 

phy0 wlan0 wl Broadcom Limited BCM4352 802.11ac Wireless Network Adapter (rev 03)
phy6 wlx002522508b5d rt2800usb Ralink Technology, Corp. RT2870/RT3070
Interface 15mon is too long for linux so it will be renamed to the old style (wlan#) name.

(mac80211 monitor mode vif enabled on [phy6]wlan1mon
(mac80211 station mode vif disabled for [phy6]wlx002522508b5d)

I then try

sudo wash -i wlan1mon

it returns

[X] ERROR: Failed to open 'wlan1mon' for capturing

I have tried substituting wlam1mon for [phy6]wlan1mon, [phy6], [phy6]wlx002522508b5d, wlx002522508b5d and they all return the Failed to open error.

Where an I going wrong please?

Thanks for any help

 

[Please start PineAP and try again]

Yes after a reboot it worked fine. Thanks for the help.

[Please start PineAP and try again]

I believe I have set up my new Pineapple Nano OK. However when I try and 'Deauth' I get the error 'Please start the PineAP and try again'

In the PineAP menu I have everything checked ie

Allow Associations, Log Probes, Log Associations, Pineapple Daemon Enabled, Capture SSIDs to Pool, Beacon Response & Broadcast SSID Pool.

What might I be doing wrong to get this error?

Many thanks for any help
