EDUP EP-N8508GS with Wheezy Raspbian and wpa_gui

Tue Feb 11, 2014 12:20 am

Hello everyone,

First of all, I am sorry about my English.

I used the current last version of NOOBS (1.3.4) to install Raspbian (I guess that it installed the last version of Raspbian, the same as 2014-01-07-wheezy-raspbian.zip).

All seems to work just fine but the wifi connection.

My router uses WPA2 but I tried to use WPA, WEP and even set no security. I also changed channels, SSID, etc... without success.

I also tried several USB chargers (and also plugging the Raspberry PI to an USB computer port) because I thought maybe it was a problem of power supply.

I tried another dongle from another brand and it works fine with wpa_gui. It connects to my wifi and works all perfect.

So the problem seems to be in the dongle itself and not in my router or charger. The wifi dongle I am trying to make it work is an EDUP EP-N8508GS (sold in many online shops specialized in the Raspberry PI). I tried to run wpa_gui as root but it does the same. By the way, I own two EDUP EP-N8508GS and none of them work.

When I open the wpa_gui, it lists the wlan0 and I can scan the access points and I see my SSID listed. Then I chose it and configure it properly, but when I try to connect it just loops all the time, showing the status in "Scanning" and "Associating". The event history (File/Event History in the menu) shows all the time the same (many times the same sentences):

Trying to associate with e0:91:53:5f:18:9c (SSID='WLAN_11' freq=2452 Mhz)
Association request to the driver failed
CTRL-EVENT-DISCONNECTED bssid=e0:91:53:5f.18:9c reason=0
CTRL-EVENT-SCAN-RESULT
WPS-AP-AVAILABLE

It seems that there is a problem with the driver but I can't figure out the solution. I thought the dongle should work out of the box with the new version of Raspbian but it doesn't.

I have tried to install again the whole system several times but I always end with the same issue.

Could anyone help me, please?

Thank you in advance,
Joan

Thanks fruitoftheloom,

In stead of "EDUP EP-N8508GS" I have a "TL-WN725N-v2", but the error is the same.
My wifi is encripted with WPA2+AES.
The report of "lsusb" with the adapter plugged is:

Bus 001: Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001: Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001: Device 003: ID 0424:ec00 Standard Microsystems Corp.
Bus 001: Device 004: Id obda:8179 Realtek Semiconductor Corp.

I think that the last one is my wifi adapter.

Could you help me with this poblem?

Thank you very much!
