Thanks, I guess I’ll have to try that. I can’t keep up. I thought 6.29 was the latest.

If I have a problem client like that and some troubleshooting doesn’t fix it I upgrade just that client to the latest. Mikrotik routinely leaves things out of the changeling that were fixed. They are getting better. WMM support has been an issue across many brands of routers. The Apple boards talk of WMM support being turned off and fixing issues. 6.30 *) wireless - added WMM power save suport for mobile devices; 6.22 *) 100% CPU load caused by DNS service fixed; *) 100% CPU load caused by unclassified services fixed; Justin --- Justin Wilson <j...@mtin.net> http://www.mtin.net Managed Services – xISP Solutions – Data Centers http://www.thebrotherswisp.com Podcast about xISP topics http://www.midwest-ix.com Peering – Transit – Internet Exchange On Jul 14, 2015, at 11:16 AM, George Skorup <geo...@cbcast.com> wrote: I have a RB751 at home. My Moto X's wireless likes to just stop passing traffic. I log in and see a bunch of deauths and key timeouts in the log. I had the preamble set to both and changed it to long the other day. I also updated it to 6.30 last night before I went to bed. So I'm hoping one of those fixes it. This also happens with my phone and others in the office on the Unifi though, but a lot less frequent. MT wireless is just.. different. On 7/14/2015 5:14 AM, Ken Hohhof wrote: I assume you had it on both (the default), not short, before the switch?

The complaining customer called today and said the issue is 99% fixed after I changed the group key exchange from 5m to 60m, which unfortunately is as long as RouterOS lets you set it. I believe this is the interval for rotating the group ciphers, not the timeout for the exchange. Not sure why the Apple devices seem to be not doing the handshake for the new keys, resulting in them getting deauthed and disconnected. The only other thing I am considering is changing channel width from 20/40 to 20 MHz. There’s a list of tips from Apple that says to do that in 2.4 GHz, but they seem to imply it’s for compatibility with other devices, not specifically iOS devices. The other thing Apple recommends is enabling WMM, I’m not sure if that’s a good idea, especially since Mikrotik doesn’t support WMM sleep mode, AFAIK. I’m not sure why just the QoS part of WMM would prevent a client from getting disconnected.

I do understand what you’re saying about the changelog – Mikrotik may have changed/fixed something from 6.19 to 6.29 silently without noting it in the changelog. I was kind of hoping someone knew a trick to get the Netflix app to just keep playing rather than popping up an error message. Or had seen this problem before and knew how to fix it. The group key exchange timeout may be a red herring. I’m not sure if Mikrotik is doing a good thing by kicking the client off when the group key exchange fails after a key rotation. I guess it prevents a situation where the client can’t talk to other clients on the same LAN because multicast/broadcast traffic isn’t getting through. But maybe it would be less intrusive to just wait for the next key rotation to restore that functionality rather than forcing a disconnect. Also I’m not sure why they won’t let you set the key rotation interval longer than 1 hour or turn off rotation entirely, probably for security reasons.

There may not be an issue with a given product and two versions, but it's a good habit to get into. Mikrotik's changelog is like cheating on your spouse. Everyone sees you behaving differently now, but there's no official paperwork showing it. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------------------------------- From: "Ken Hohhof" <af...@kwisp.com> To: af@afmug.com Sent: Friday, July 10, 2015 8:06:13 AM Subject: Re: [AFMUG] Netflix app on iPad keeps asking to reconnect This particular router has Routerboard FW 3.18 so I think it was upgraded to 6.19 not downgraded. Also, I don’t see any wireless related changes in the changelog from 6.19 to 6.29. I’m thinking of changing the group key update interval from 5m to 1h which I think is the max. I’m not sure if the group key exchange timeouts are due to the client being in sleep mode, or a problem I should be worrying about. The fact that the Mikrotik sends deauth to disconnect the client which then immediately connects doesn’t seem like a good think. Without the deauth and disconnect, I would not expect unicast traffic to be affected. I’m thinking the iPad knows the WiFi disconnected and tells the app which then pops up the annoying error which requires the user to tap OK and then Play. If I change the timeout to 1h and the frequency of the problem stays the same, I think that will eliminate this as the possible cause. Reading the logs can be confusing, it’s amazing how many iPhones and iPads one family can have. Hard to sort out the problems from normal events.

I've even been downgrading the latest shipment of 951G's that came in with 6.23. Usually switching to Mikrotik from store bought routers solves a lot of iPad/iPhone problems for us. He said this is the latest iPad, would that be the iPad Air 2?

I assume you have upgraded to the latest version of RouterOS. This is one of the few times running the latest helps. I was running 6.21 on one of my APs in the house and anytime I roamed to it things became very slow. OS upgrade helped. Is this an iPad, Ipad2, iPad Air?
