Hi, I seem to not be able to connect properly using my USB wirelss rtl8192cu

out of lsusb

Bus 001 Device 002: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN

When I run nmcli -p con I get the following

======================================================================================================================
                                                   Connection list

iwconfig shows not connected

lo        no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr=2347 B   Fragment thr:off
          Power Management:off
          
eth0      no wireless extensions.

I then have to run

sudo wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf to get a connection,

and then

dhcpcd wlan0 to get an IP

I can then see the laptop connected on the DHCP clients list on my router however cannot browse any web pages

dmesg output is below

Has anyone been able to get this working properly? Or would have any thoughts on what might be causing this?

so in a bizarre twist the wireless now works.

Reinstalled some drivers yesterday and did an update today, not sure which fixed it not complaining.
