R700 keeps dropping connections of all connected users

unknown

Hi guys,

I have an R700 running at my workplace that has about 50 people connected (approx. 75 devices). The encryption type is AES.

What reasons could cause all users to simultaneously be kicked off?

Thanks

Sam

A reboot of the AP (for reasons unknown) would do it. I assume you have ruled this out.

Hi Sam,

Few reasons i can think of

1. Channel change,

2. AP software crash which may result in AP reboot As

3. brief Power outage.

if this is happening on a regular basis and you can check the same by looking at its support file which will tell on disconnects.

hope this helps.

Hope this

We haven't changed the channel of the router (perhaps a neighboring one has?) and the unit runs on a backup battery with a number of other devices, so I can rule out power outage.

That leaves a crash of the software. Is there anything in particular I should look for in a the logs?

Hi Sam,

If AP is using channelfly feature then whenever it changes channel then there would be brief disconnect.

For AP crash, you need to see the AP support file and support team is trained to detect AP crashes from it.

Hope it helps.

Hi Sam Littler,

You have already mentioned but Just to re-confirm , it is happening only with one AP ?

If so , Try disabling the channel fly and configure a static channel on the AP and monitor if you see this issue again.

Thanks ,

@Munish, we only use 1 AP.

A scan shows that the wireless router upstairs changes channel rapidly (every few seconds).

The log shows several channelfly channel changes due to interference.

If the wireless router upstairs were to change to a channel that was being used by our access point, would that be sufficient to cause it to change channels and disconnect everyone?

Hi Sam,

Channelfly will change channel if it finds a channel which can give better performance than the current one and one of the reason could be wireless router upstairs changing to a channel that was being used by R700.

I have noticed from my experience that old generation chipset tend to take more time to reconnect hence disconnection is noticeable.

Hope this helps.

Hi Sam,

Are your users able to reconnect to the R700, or do you need to reboot it?

Sam, Please contact Ruckus Tech Support for the current latest recommended R700 firmware image, currently 9.8.2.0.24, which has some important fixes and I believe may address your reported problem.
