Hello all,

I have a problem connecting some APs using the snippets installed with WICED. I have five wifi APs available, but can only connect with three of them. With the other two I cant. Ive tried several settings like other channel, other security (WEP/WPA/WPA2), wifi mode (b/g/n), other SSID and passphrase, but none of the changes in the setting of the AP will make it work.

Ive also copied all settings of a not working AP to a working AP and than I can connect to that AP with the same settings (and SSID and passphrase).

Strange enough I have a precompiled firmware file delivered by the supplier of the SN8200EVK kit im using, and if I execute this firmware the module can connect with the AP where the snippets cant connect with. So probably its not the hardware, because this firmware can connect with the AP.

Does anyone have or had the same or similar problem? and how to solve this?

Modules Im using:

ISM43362_M3G_L44 (Inventek)

SN82xx (muRata)

Wiced version:

WICED 2.3.1 (also corrected the known issues, july 4, 2013)

APs I cant connect with, using the snippets:

ASUS RT-N10

HW version: B1

FW version: 2.0.2.1

TP-Link TL-WA830RE

HW version: WA830RE v1 00000000

FW version: 3.12.17 Build 111108 Rel.31187n

With kind regards,

As I looked at the traces I noticed that Wireshark has flagged almost all the packets from the bruwifi-guest AP as malformed.

On one of the failed join attempts I looked at the bruwifi-guest AP didnt reply to any of the client devices Authentication requests. Endless 802.11 retries before the client gave up. This could simply be low signal strength due to the distance between the client and the AP or could be a sign of a busy RF environment or poor RF performance of the board.

WICED, unlike PCs, tablet and phones, is very aggressive and unforgiving in classifying a failure to join to ensure energy is not wasted by the device attempting to join a non-existent AP.
