Cannot Aquire IP TP-Link (TL-WN725N)

[ylafont]

Hoping someone can point me in the proper direction.

I have been trying to setup a TP-Link TL-WN725N (V2 i think) on raspian 3.12.28+ #709

Downloaded driver from here.

Checked to make sure device was listed in lsusb

iwlist scan displays a list of all the accesspoint but i cannot make a connection

i have tried
iwconfig wlan0 essid "MyNetwork" key "s:password"
iwconfig wlan0 essid "MyNetwork" key "hex_password"

and i have also turned on the guest access network with no security or password and still cannot obtain an IP

syslog displays

Wired works without a problem. and other devices can obtain ip address successfully.

anyone have a clue?

Thanks...

I don't think the driver is my problem. I think it is a Wireless Security Key problem with WPA2.

After trying different option i still cant make a permanent connection. I think i was able to make a connection once or twice. but that is about it. Not sure where the problem exist.

/etc/networ/interfaces

Code: Select all

auto lo wlan0

iface lo inet loopback

allow-hotplug eth0
iface eth0 inet dhcp

allow-hotplug wlan0
iface wlan0 inet dhcp

I remmed these out. not sure if there were doing anything.
#wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
#pre-up wpa_supplicant -DR8188EU -i wlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf -B -P 
#/var/run/wpa_supplicant.wlan0.pid
#post-down killall -q wpa_supplicant

#iface default inet dhcp
#        wpa-ssid ConnectAndDie
#       wpa-psk 36407839b47d35e278e08cf9cc8225ae8afe1394468712867512b07985cbda3a

/etc/wpa_supplicant/wpa_supplicant.conf

Code: Select all

network={
	ssid="MyWireLess"
	proto=WPA RSN
	key_mgmt=WPA-PSK
	pairwise=CCMP TKIP
	group=CCMP TKIP
	psk=36407839b47d35e278e08cf9cc8225ae8afe1394468712867512b07985cbda3a
}

If I issue the command

Code: Select all

sudo iwconfig wlan0 essid "MyWireless"  key "36407839b47d35e278e08cf9cc8225ae8afe1394468712867512b07985cbda3a"

if get connected

pi@PiScanner ~ $ iwconfig

lo no wireless extensions.

eth0 no wireless extensions.


and still no ip when

sudo dhclient wlan0 is issued
