Al Butler proposed the following answer:
Have you tried disabling networkmanager and setting up connection
manually?

if you do this the lines in your /etc/network/interfaces should look
something like this:

auto wlan4
iface wlan4 inet dhcp

If you are using WPA for your wireless connection you will need to add
these lines:

wpa-driver wext
wpa-conf /etc/wpa_supplicant.conf


Then configure the wpa_supplicant.conf:

sudo nano /etc/wpa_supplicant.conf

and add these lines if you are using WPA-PSK:

ctrl_interface=/var/run/wpa_supplicant

network={
	ssid="my wireless ssid"
	scan_ssid=1
	proto=WPA
	key_mgmt=WPA-PSK
	psk="my wpa passphrase"
}

For configuration for other types of encryption see:
