CC3200 Failed connection with WEP router/AP!!!

Other Parts Discussed in Thread: CC3200, CC3100

I have tried to connect CC3200 to WEP router/AP but it failed all the time. After that I switched to WPA2 router/AP, It worked right at the first time. Is there something wrong?

Does anyone try with WEP router/ AP?

Thanks,

Loc Nguyen

    Hi,

       I thing most WiFi Router uses WPA. I have been able to connect my CC3200 Laucnhpad to my WiFI Router using WPA.

    First of all, you should be using WPA2 if available, as it is a lot more secure than WEP, which has a security flaw (search Google for "WEP Security Flaw" for more details).

    The issue you may have come across with WEP, is related to the actual Passcode and the use of only Hexadecimal digits, and possibly the length of the Passcode. I will not go into further detail, as WPA2 is the way to go.

    I am not going to use WEP but my point is does anyone test the code with WEP mode? I want to be sure WEP works.

    I have programmed  a couples wifi modules but I think  CC3200 is more likely to be good for small project based without adding an additional microcontroller. Does anyone test CC3200 out the field? industrial environments?

    Thanks,

    Loc Nguyen.

    I have not tested WEP my self, and of course you are right it needs to work in environments where it is the only option available. I'd be pretty confident it works, and suggest you look into requirements around length and hexadecimal characters only. I know these 2 factors often come into play with WEP.

    Perhaps someone who is using WEP can provide some additional feedback.

    Glenn.

    Thank you for response Glenn,

    I am not new with wifi so I should know the settings WEP, WPA2.... Basically, there is much more to discover CC3200 before making a real product with it. I should close this post.

    Sincerely,

    Loc.

    Hi Loc,

     

    We are conducting a full security matrix tests checking all our supported method.

    We also use big number of AP to verify the solution.

    If you are seeing an issue with a specific AP we will be interested to know.

    Can you help me obtaining this info:

    • Which AP module you are using (module, HW and SW version)?
    • Which WEP option are you using?
    • Were you able to connect any other device to the AP with WEP security (mobile device, Laptop Etc')

    Best Regards

    Hi Nir,

    I have also some problems with WEP. I have done some smart config testing and I not able to connect to a WEP secured network.

    The device (CC3100) receives the smart config stuff (SL_OPCODE_WLAN_SMART_CONFIG_START_ASYNC_RESPONSE) but is unable to connect to the AP. (no SL_WLAN_CONNECT_EVENT).

    AP used: Zyxel P-320W

    Security Mode: Static WEP

    WEP Encryption: 64 Bit

    Pwd Mode: Ascii (e.g. 12345)

    Best regards,

    David

    Hi David,

    SmartConfig application (as is) support only WEP Hex Format - this is the rich format that can enable more options than ASCII.

    The application can be modified to accept ASCII format and convert it to Hex format in order to work with the SmartConfig on the device.

    More details on WEP Hex/ASCII format can be found in here: http://processors.wiki.ti.com/index.php/CC31xx_Programmers_Guide

    I hope it answer your question.

    Best Regards,
