I am having trouble connecting the WiFly board to local WiFi network. I've tried it with security turned on (WPA2) and with it turned off, I keep getting Disconn from acumen4,AUTH-ERR. I am hoping someone can spot something. Here are results of a scan:
Code: Select all
SCAN:Found 1

 1              acumen4 09 -59    Open 00:0c:41:c2:56:c0   2104    0
Then I say: join acumen4. I get this in response:

So it seems like it worked, but it did not, because I send show net and get this in response (e.g. DHCP failed):

I've tried factory reset - did not work.
So what am I missing here?

The "Open" implies there is no password/phrase required.

Is there MAC-based access control in use on your Access Point?

I would suggest looking at your Access Point logs for an error message.

Does your router list the WiFly module as successfully connected?

What model WiFi Access Point do you have?

Correct. As I mentioned I tried it with security and without. All the logs I posted were tried when I turned off security on the router.
Is there MAC-based access control in use on your Access Point?
No.
Does your router list the WiFly module as successfully connected?
I'll have a look at it tonight and will update the answer.
What model WiFi Access Point do you have?
Just your standard Linksys WG54 wireless router.

So I checked the router and, no, it does not show the WiFly module as being connected.
I also checked the router logs, but it only shows incoming and outgoing data requests, not connection requests, so nothing from the WiFly module.

One thing that I don't get is why I am getting an authorization error when trying to connect to a network with no security:
Code: Select all
Disconn from acumen4,AUTH-ERR
Another thing that is suspect to me (but keep in mind, i am a noob) are the following settings (when I hit get everything):
Code: Select all
User=roving
Pass=Pass123
Passphrase=rubygirl
Should I set these settings (i am assuming these are defaults) to empty, since the network is empty? If so, how do I set them to empty?
#117830
Ok, the good news is that I got it working.

First, I happened upon a fella with a similar problem (viewtopic.php?f=13&t=24408), who suggested that bad grounding on the WiFly cards cause RF interference. So I moved the WiFly card as far away from the parent device as I could (few inches) and lo and behold it worked. It connected to a wifi network with NO security.

Then I tried to make it connect to a network with security and it just wouldn't do it. I kept on getting AUTH-ERR. I tried all types of supported security schemes (as listed in reference guide), but nothing worked. Finally, I nailed it down to my password having a space in it. The ref guide states that spaces should be replaced by $ dollar signs, but this does not work. When I changed the password not to contain spaces, everything worked great.

Hope this helps the next dude.

Hi

I'm getting the same symptoms as mentioned here, and in the original post regarding "bad grounding". Unfortunately I have a WiFly bee so moving it away from the Arduino isn't such an easy task. I'm also using a Bees shield, from Seeed, in case this detail matters.

I can connect to my notebook in adhoc mode, but no matter if I have security set or open on the my wlan the WiFly cycles through this behavior :
Code: Select all
Auto-Assoc CANEFIRE chan=11 mode=WEP SCAN OK
Joining CANEFIRE now..
Disconn from CANEFIRE,AUTH-ERR
Auto-Assoc CANEFIRE chan=11 mode=WEP SCAN OK
Joining CANEFIRE now..
Auto-Assoc CANEFIRE chan=11 mode=WEP SCAN OK
Joining CANEFIRE now..
Is there a way to improve the situation for a WiFly Bee by shielding it, or any other creative means? Happy to try whatever it takes.

The Netgear APs on the home wlan will only bridge & repeat using WEP in case you're wondering why I'm bothering with that. They're due to be replaced in a month or so, but can bring that forward too in the unlikely event that's contributing to this issue.

Thanks for any advice you can offer,
Geoff
