Re: WAP321 Wireless-N Access Point connecting problems

bogdan806 · ‎06-03-2013

Hi,

We have a WAP321 WAP321-E-K9 V01 and it worked just fine for about 4 months but now for unknown reasons and not in a specific time, I doesn't let any devices to connect.

For example (most often) at the 1st hour of work all 10 computer can connect with no problem, but if another device is trying to connect it stucks at "obtaining IP address", the computers/devices that are connected can disconnect and reconnect at any time.
We have a maximum 20 devices that connects including 10 computers, about 5-8 mobile phones and 2 laptops.
In any case, if the access point is rebooted it works fine, for some time.... I've upgraded the firmware to 1.0.3.4 and the same problem.
We have only one network configurated on it, I've attached a file with the exported diagnostics.

Hi Bogdan, my name is Luis I am part of the Small business Support community. I apologize for your inconvenience you are having, I have a couple of question for you.

1. Did you try to use different security strength? (Also try to use a short password)

2. Did you configure any access rule?

I will share a document with 10 tips in order to improve your wireless signal.

I hope you find this answer useful, thank for using our forum.

Hi Luis,

1. The password is 8 character lenght and it's something very basic.

2. I don't have any access rule.

3. The wireless signal is not a problem I can see it 100%.

I don't think my problem is related to this, as after a reboot all goes to normal.

After a time it simply won't accept any new devices.
Are the some features that I have to enable/disable? Will a factory restore will help? Or is simply the case to send it to services?

So, Cisco support can't offer anything else beside this?

Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center. Thank you for using the Cisco Community Post Forums.

I have read through your diagnostic file and see that it was taken after only 5 hours of uptime.

It shows that there was currently 19 devices connected at the time of the snapshot.

Was there any issue's going on at the time this was taken? If not, since this only does a real-time snapshot of the system at that moment. May I ask that you do another during a time when it is not allowing connectivity to the device. If this does not give us any better information I may need you to call in and open a case with one of the engineers so we can gather some wireless packet captures.

Thanks

Thank you for your reply Eric!

I will export the diagnostics again when we'll have connectivity problems.

I think until tomorrow you will have it.

Many thanks!

bogdan806 · ‎06-13-2013

Hi Eric,

This morning we had this issue again, I've downloaded the diagnostics and after a reboot all is good, as usual.

Please find attached the file.

Many thanks!

Hi,

I have 4xWAP321 in cluster connect to SG300-8MP.

After 5-7 days hungs.

Today 1 respond and 3 are hung

I attached two files, one before restart all AP and one after restart.

Thanks,

Eric Moyers · ‎06-13-2013

I have your file and have looked through it. Right now only two things seem to stick out to me.

From the wlan0 interface I see was some transmission errors. Shown below on the line begining with TX

This one was also having errors. See last line, rx decrypt failures

What is the device with this MAC address? If it is turned off, do you still experience issues?

Eric

Mr. Craiu, I am looking at yours next.

Eric Moyers · ‎06-13-2013

Mr. Craiu, I have been looking over yours. When you say 1 will respond three are hung....

Are you talking about SSID's? I only see one configured on both files.

SSID: Noriel

Also when these were taken thee were no devices connected to the WPA's. So I can not see any TX, RX Packets.

PLese connect something and redo the files.

Thanks

Hi,

All 4 devices are configured in a single cluster.

Only one I was able to connect via http interface, of the 4 devices. The other three devices not answering ping

I have attached files of all equipment

Thanks,

Alexandru Craiu

alex · ‎06-13-2013

Hi,

I can not identify with that mac address equipment

Thanks,

Alexandru

bogdan806 · ‎06-14-2013

I'll scan the network today for that device, but after I rebooted the Cisco AP, it was able to connect 100%.

At the moment this is what I do, when I get reports that someone is not able to connect, I reboot the access point and everyone can connect to it.
Also I've done some tests changing the wireless frequency to all options (802.11a- b/g - a/n - b/g/n - 2.4GHz and 5GHz) with no luck, same problems

bogdan806 · ‎06-14-2013

Here, I have another example, just minutes ago this computer(the user logon later than the others)

MAC: C8-D7-19-0C-57-97

was unable to connect, network status: limited or no connectivity

I've exported the diagnostics to diagnostics_before_changes, then changed the wireless to 802.11 b/g/n (or if I would just reboot) the computer was able to connect and I've also exported the diagnostics to diagnostics_after_changes.

I don't think the frequency is the issue because all computer have the same wireless adaptor (Adaptor Cisco Wireless-N Linksys AE2500, Dual-Band, USB) model and only this one was not able to connect.

Also I rebooted the pc and the wireless adaptor before trying this and that didn't helped.
