Im running 3.5.1.0.862 firmware. Clients are getting dropped randomly

Im running 3.5.1.0.862 firmware. I have one site on my system that is having all kinds of problems with staying connected to the network. The wireless device will connect to one ssid and than randomly disconnect and have a mic error code or loss on connection like it loses its pre shared key. I can move to another access point and it will connect just fine. It seems very random. It started basically day one so I did an upgrade and now the ap's are in alarm. They are being flagged. Ruckus says just ignore the flagged error if they are not dropping. Well they are dropping clients. Anyone see this before.

Hi Aaron,

Do your VLAN tags exist on all of the switch ports?

Yes.  The public internet ssid has a tagged vlan across all the ports on the switch.  The switch ports are setup as a hybred.  The ruckus ap is managed with a untagged pvid and the customer traffic is on a tagged vlan.

Hi Aaron,

Great. That is 95% of all issues usually. I have to triple check the switch configs if I didn't do the config myself. 

Moving forward is where it gets interesting,

- Are you using any sort of authentication mechanisms?
- Are you using Dynamic VLANs?


Best,
Alex

no dynamic vlans, and authentication only through the ruckus.  no radius.  using wpa2 pre shared key set to auto.  I did try aes only and it seemed not to help.

Aaron,

What are the devices (phones, tablets, proprietary devices) that are getting dropped?

Are you in US? Are you using DFS channels?


Can you attach a text log or a link to a text log from a WAP that is having the issue you are describing?


Best,
Alex

It has happened on ipads, hp tablet, smart board, and laptops.  I will copy a log to post it.

Are you having to re-enter credentials? Or just by moving you can get it to "snap" back without further intervention? What's your min bss-rate set to? Is it set to something super aggressive (24 Mbps)?

Its random.  But I can move from one ap to another or one ssid to another and get the error. If I go back to the other ap or ssid than it will connect again.  I believe it was set for 24 mbps.  I cant find the setting now after the upgrade.

stuff to check:

Channelfly - do you have this enabled? Do client disconnections tie in with channelfy events (when CF changes the channel).

a CSA (channel switch announcement) is used notifying a client when an AP is changing channel however after using Ruckus stuff for many years with 40k+ AP's I frequently see stations not following the CSA and getting disconnected. Also if your using channelfly, when an AP is rebooted (as in the case of your firmware upgrade) CF must reassess every channel which usually results in AP's rapidly switching channel for anywhere upto 24 hours, user service during this period can be very flaky. 

Same deal for DFS. Are you seeing DFS events taking place which correlate to users disconnecting. This is a pretty common one for 5G clients getting disconnected when using the DFS channels.
