Clients still getting kicked from AP.

jason_sparrow — Wed, 28 Oct 2015 07:50:06 GMT

I think the various questions i am asking are getting lost in other threads so....

Could someone tell me why i'm seeing this...?

"wmi_peer_sta_kickout_event_handler:838 Kicking off STA *************** AID 1"

I am also seeing the above, but with AID 2 at the end.

Thanks.

Anyone?

I'd open a ticket with tech support and provide your ZD debug/AP support info
and describe your environment and if you're having a problem with one or more
clients, all the same device type or various, and what you're seeing from that
client side.

Single line above is not enough to determine if it's a client roam/leave, or a feature
like band balancing/band steering or SmartRoam, etc.

What AP are you seeing this behaviour on?

Have you seen it on more than one AP?

What firmware are you running and have you tried other firmware?

Have you done a promiscuous sniff to see whats happening airside?

How is the network confured?

Whats the max-aid value on your radios set too? :

get max-aid wlan0
get max-aid wlan32

Thanks Michael, and may well do.

Hi Sean....

It is happening on the R600.

Latest standalone firmware (...432) and yes but still the same.

Rogue AP's are listed but have very weak signals.

Network is 2.4ghz for most clients, and i have 5ghz for my MBP and iPhone6s.

Ill check out the Max Aid values when i get home.

Also, my iphone was the only client connected last night (5Ghz) and it was kicked off (Reason 0) at around 04.11 just after this in the log, which i havent noticed before...

"ieee80211_find_best_vht_channel:2753 ***** pick 20MHz channel 140 flags 0x2201100"

wmi_peer_sta_kickout_event_handler:838 Kicking off STA *************** AID 1:

this could either be inactivity timeout or tx failure in high noise environment

(confirmed by Ruckus support)

As i see it it is normal behaviour and the AP is reacting to something.

Re: Clients still getting kicked from AP.

seanmuir — Mon, 02 Nov 2015 11:40:42 GMT

was your client passing traffic at the time?

Re: Clients still getting kicked from AP.

jason_sparrow — Mon, 02 Nov 2015 13:06:03 GMT

not as far as im aware as the above was logged at approx 4am today

This is what i get from the commands you gave above...

get max-aid wlan0

Max Assoc ID is 512

rkscli: get max-aid wlan32

rkscli: get max-aid wlan8

Max Assoc ID is 180

wlan0 is what the 2.4 clients & network is operating on and wlan8 is for 5Ghz.

Do clients ping an AP to keep them connected so that this doesnt happen?.

My environment is reasonably 'noise' free, especially during the night when most of these issue seem to be occurring.

Re: Clients still getting kicked from AP.

seanmuir — Mon, 02 Nov 2015 14:48:48 GMT

OK so your max-aid value is not impacting clients being kicked or stopping them from connecting.

I would say that unless you are seeing any issues with clients not being able to connect or are being kicked during connection i.e. watching You Tube and then your suddenly offline (other entertainment websites are available), that there is no reason to be concerned with outputs from the log of the AP.

What I would say is that if you have session idle timeout configured on the AP/ZD then this value should be set to be the same as your DHCP lease value as I have seen this to cause issues in the past

Note: In my home network I have the session idle timeout value within my WLAN on my ZD set to 600 minutes.

Thanks Sean,

My DHCP leases on my router are set to the default which is 1500minutes so i guess that rules that out, but then, should my AP match the router or is there no way of altering the AP as im on stand alone firmware?

My iPhone also doesn't seem to always connect straight away when i have been out of the building and return, and sometimes its a fair few minutes before it does connect.

My only reason of concern with the logs is that again i got up this morning to find my phone had dropped back to 4G, and when i checked the log again when i got up, it showed a channel fly, just before the kickoff (AID 1) which now appears the reason that my phone was disconnected, but then reconnected when i unlocked it. (the last actual wifi use was around 11pm as i check emails before i go to bed).

What i don't understand is why it gets kicked (Aid 1, and then also Reason 0) but then doesn't reconnect? There is plenty of signal there.

The frustrating things is, is that this doesn't happen every night, and when it does, the log seems to show a different reason each time, although not always.

If need be, i will open a support ticket, however, i'm not overly convinced there is a solution.

Hi Michael,

I have opened a support ticket for someone to have a look through, even if it is to confirm everything looks correct..

Thanks

Anyway, apologies for all the questions.

i appreciate that these products are primarily for enterprise use, however, i would like to understand how they work as much as possible so that i can learn what to look out for when ther are problems such as this.

🙂

Mobile devices always disconnect when not in use to save power, at least every iPhone I've ever had and many Android devices I've seen do. I would consider that completely normal. In the case of my iPhone when I wake it up and unlock it it reconnects and away I go.

john_d — Mon, 02 Nov 2015 23:58:06 GMT

Do you still have ChannelFly or SmartRoam enabled? I've definitely noticed that my iPhone, if kicked off a network via SmartRoam, will not bother using the wifi network again for several minutes unless I manually reconnect it.

If you are having random client disconnect problems, I would highly recommend going to a static channel assignment and disabling smart_roam if you had turned it on as a part of your roaming optimization attempts.

I've got a household of 15-20 Apple devices and have not seen any connectivity / disconnection problems with them.

Re: Clients still getting kicked from AP.

I would monitor the reason Codes and see what your getting.

Reason Code 0 is a funny one as it's reserved:

https://support.ruckuswireless.com/answers/000002430

Usually you see Reason Code 4 or 8 - none of which are anything to worry about.

If you are just having issues with reconnecting on an irregular basis, have you tried other devices and are you seeing the same behaviour, or is it specifically tied to the iPhone?

seanmuir — Tue, 03 Nov 2015 01:36:14 GMT

wow you have an iPhone that works on WiFI - consider yourself privileged 😉

bill_burns_6069 — Tue, 03 Nov 2015 03:33:34 GMT

Thanks for confirming that this (smartroam problem) is "normal".

In my case it seems like the iPhone gets smartroamed back and forth between APs several times, and then gives up on WiFi "permanently". (or until the device gets locked/unlocked, etc.)

There are courtyard areas between buildings where this often happens.

I've had this user complaint many times, and mentioned it to tech support many times without hearing any explanation/confirmation.

smartroam solves serious roaming problems for me, but if I use it, I shouldn't expect my iPhone devices to work...

Re: Clients still getting kicked from AP.

john_d — Tue, 03 Nov 2015 06:42:52 GMT

Yeah, I don't know what's "normal", but it definitely feels like the iOS devices take SmartRoam disassociations to mean "please don't connect to me for a while"... I've found bss-minrate is a more effective mechanism to reduce coverage radius for iOS devices.

I've also found that even for WPA2-PSK networks, enabling 802.11r/k (such as in a controller environment or possibly in Unleashed) causes iOS devices to roam more frequently. Ever since I turned that on, I haven't had a need to further change roaming related settings.

Hi Dave/all,

I have now disabled SmartSelect and last night after looking through the logs i had no issues with my phone disconnecting.

However, its early days yet as this does happen randomly.

As for roaming, it seems to work ok for 80% of the time, but there are occasions were it takes a minute or two to realise there is a better signal much closer.

It appears to roam better from an R600 to an R500, but sometimes struggles to go roam back from the 500 to the 600. (both running latest stand alone FW).
