Постоянное отключение устройств iPhone от точек доступа беспроводной сети CAPSMAN

Имеется 4 устройства Mikrotik:

RB2011UiAS-2HnD — 1 шт.
RouterBOARD-wAP-2nD-r2 — 1 шт.
RouterBOARD-cAP-2nD — 2 шт.

Все устройства объединены в проводную локальную сеть с использованием бриджа на устройстве RB2011UiAS-2HnD.

На RB2011UiAS-2HnD настроен сервер CAPSMAN (а также CAP клиент), на остальных устройствах (точках доступа) настроены CAP клиенты.

Конфигурация остальных CAP-клиентов:

К беспроводной сети подключаются различные устройства, такие как: Android, SmartTV, Macbook, iPad, iPhone.

С подключением к беспроводной сети всех устройств, кроме iPhone, проблем не наблюдается.

На устройствах iPhone наблюдаются проблемы, а именно:

Через разные промежутки времени устройства iPhone отключаются от беспроводной сети. После отключения необходимо вручную зайти в настройки WIFI и, либо вручную нажать на подключение к точке доступа, либо просто дождаться когда система подключиться к точке доступа, в это время необходимо находиться в настройках WIFI.

Пробовал изменять различные настройки CAPSMAN в соответствии с советами, найденными в сети по данной проблеме. Изменяли частоты, мощность сигнала, тип шифрования и т.д.

Техподдержка советует изменить b/g на b/g/n и поиграться с мощностью сигнала, что, впрочем, было сделано изначально в разных вариантах.

Результат остается прежним: устройства iPhone периодически отключаются от беспроводной сети.

Один из найденных советов: изменить параметр «Country» на значение «united states», но на одном из устройств (а именно RouterBOARD-cAP-2nD) невозможно изменить этот параметр (можно выбрать только russia3 в соответствии с законодательством, устройство далеко, Netinstall применить невозможно), поэтому при изменении параметра «Country» на значение «united states» на сервере CAPSMAN, устройство RouterBOARD-cAP-2nD не подключается к серверу CAPSMAN и, таким образом, не участвует в создании бесшовной сети.

Возможно, у кого-то были такие проблемы. Прошу помочь любым советом. Спасибо!

Mikrotik и Iphone. Проблемы с wifi

Правила форума
Как правильно оформить вопрос.
Прежде чем начать настройку роутера, представьте, как это работает. Попробуйте почитать статьи об устройстве интернет-сетей. Убедитесь, что всё, что Вы задумали выполнимо вообще и на данном оборудовании в частности.
Не нужно изначально строить Наполеоновских планов. Попробуйте настроить простейшую конфигурацию, а усложнения добавлять в случае успеха постепенно.
Пожалуйста, не игнорируйте правила русского языка. Отсутствие знаков препинания и неграмотность автора топика для многих гуру достаточный повод проигнорировать топик вообще.

1. Назовите технологию подключения (динамический DHCP, L2TP, PPTP или что-то иное)
2. Изучите темку «Действия до настройки роутера».
viewtopic.php?f=15&t=2083
3. Настройте согласно выбранного Вами мануала
4. Дочитайте мануал до конца и без пропусков, в 70% случаев люди просто не до конца читают статью и пропускают важные моменты.
5. Если не получается, в Winbox открываем терминал и вбиваем там /export hide-sensitive. Результат в топик под кат, интимные подробности типа личных IP изменить на другие, пароль забить звездочками.
6. Нарисуйте Вашу сеть, рисунок (схему) сюда. На словах может быть одно, в действительности другое.

испытываю проблемы с устройствами Apple , подключенных к Mikrotik’ам. Очень слабая скорость, иногда ее вообще нет. Мессенджеры вообще пишут, что нет подключение к интернету.

Из «симптомов болезни» — неправильно присваивается IP в айфоне (присвоение — автоматически) — вместо подсети 192.168.88.хх, он попадает в 0.0.0.хх . Подскажите, может есть какие-то тонкости в настройках микротиков под эпловские устройства? На данный момент из того, что нашел в интернете в качестве решений, следующее (но все равно результата нет):

1. Ширина канала при частоте в 2.4гц выставлена 20мгц, (extension channel — disabled)
2. В настройках DHCP сервера поставлена галочка на Use ARP for leases и Always broadcast
3. Сброс настроек сети айфона делал

До этого экспериментировал с частотами и с шириной каналов, но в итоге убрал все значения (кроме п.1 выше), пусть присваивает автоматически. Проблем с другими девайсами нет — все летает

1-е Правило WiFi — Везде где только можно откажитесь от WiFi!
2-е Правило WiFi -Устройство, которое пользователь не носит с собой постоянно, должно подключаться кабелем!!

Микротики есть разные: черные, белые, красные. Но все равно хочется над чем нибудь заморочится.

Дома: [CCR1009-7G-1C-1S+] [CRS112-8P-4S-IN] [wAP ac] [RB260GS]
Не дома: [RB4011iGS+] [CRS326-24G-2S+RM] [wAP 60ad] [cAP ac].
. [hEX] [hAP ac²] [hAP ac lite] [hAP mini] [RB260GS]

UPD: все заработало, проблема была простая до безобразия: на одной из точек доступа был поднят dhcp сервер с дефолтной подсетью 0.0.0.0. Сервер удалил и все заработало. Но все равно странно, так как на других точках доступа тоже работали dhcp сервера и они, точки, были установлены в режиме CAP, а в Datapath Local forwarding был выключен (я думал, что с этими настройками dhcp сервер на точке задействован не будет) и при этом все остальные устройства «заходили» в правильную подсеть и нормально функционировали.

Спасибо за отзывы, так как без них я бы не пошел дальше, а топтался на одном месте и хаял бы Стива Джобса

I also had problems with Apple devices and MikroTiks, but they are now working fine. Let me ask you few questions.

1. What is your iOS version?
2. What is your RouterOS version?
3. What are your DHCP settings?
4. What are your wireless settings (probably most important)?

Problems on all iPhones
Settings in tp-link standard. Just wi-fi with encoding of WPA2+AES
It is disconnected nothing, everything works
Normally messages come from Viber and Skype
With Mikrotik on problem wi-fi. That generally simply doesn’t connect, through half of second stops will be connected.
Byvavet writes the incorrect password, and through time is connected.
Was that doesn’t receive ip on the local area network.
I put back tp-link, everything works ideally.

I have few devices working with 3 mikrotik APs: iPad 1, iPad Mini, iPhone 5, iPhone 5S, iPhone 4S, iPhone 6S and iPhone 7. None of them is having any problems with working. There was a problem sometime ago, but after upgrading RouterOS and iOS it started to work properly.

So I believe it’s just a matter of proper settings.

Re: Mikrotik wi-fi and Iphone = problem

Thu Apr 13, 2017 9:58 am

we were able to find the problem. It is related to the DHCP lease time.
By default Lease time on the MikroTik DHCP Server is 10 minutes. The iPhone disconnects approx after 5-7 minutes (little more than half of the DHCP lease time).
On TP-link the lease time is 120 minutes and that is why the iPhone is connected a lot longer. If you lower the lease time on the TP-link also to 10 minutes then you will see that it also disconnects in 5-7 minutes.

The solution for this is to increase the DHCP Server lease time to a lot longer time and then iPhone will keep connection to the AP a lot longer.

I experimented with different settings and finally i discovered that iphone dont like AMSDU Limit and AMSDU Treshold when set to default 8192. These both when set to 0, 256 or 4096 made stable connection with iphone and no more reconnects. I dont tryed with different values, feel free to experiment if you want. My device is hap ac, and here my config for wireless:

I followed your instruction about increasing Lease time.

all good now

If both SSIDs are good quality signal, most modern devices choose 5GHz for the speed.

Re: Mikrotik wi-fi and Iphone = problem

Thu Feb 08, 2018 7:40 pm

Hi Mikrotik Community,

I’ve problems with Mikrotik WIFI and Apple iOS devices.
At some of my customers they use a new Till System which is based on iOS.
So there is one «Master- Till» (iPad) running the Till- app with a Database and the client- devices like iPod touch, iPhone or iPad are connecting via wifi to the Database for accessing tables etc.
The connection is established via TCP port.

So when you start the app on the clients there’ll be a steady TCP connection established to the Master-Device.
This connection is sporadically breaking and then the clients can’t connect.
You have to wait till the timeout (10sec)’ll kick in or you need to restart the app.
That’s really annoying when you running a busy Bar/Restaurant.

Here is my Setup:
Running CAPsMAN on RB3011UIAS
multiple wAP_AC’s directly connected to a main-switch and then running to the CAPsMAN.
Newest FW (6.41.1) on all devices!
For testing activated only 5GHz, no other SSIDs, central bridging of all interfaces, no firewalling inbetween, only RSTP on switch an central bridge
—————-
Same with a hAP-ac (basic-config) with CAPsMAN and only the internal antennas assigned.

The client’s aren’t loosing the wifi link; you can still open websites in Safari etc.
Also run ping’s on master and all clients; there are no drops!
So what can be the issue?
Why is the TCP connection breaking all the time?
With some other brands they don’t have these issues (Aerohive, Apple Extreme. )
Even scanned the SSID’s around because of interferences/overlapping networks but the 5Ghz network is very clean

Is there any TTL setting for TCP connections on bridged or «client to client» forwarded connections?
only know the settings from «Connection Tracking» but this setting only affects traffic passing the Firewall.

Hopefully somebody knows the magic?

Re: Mikrotik wi-fi and Iphone = problem

Thu Feb 08, 2018 8:15 pm

Another test:
Connected the «Master- Device» running the database with an ethernet- adapter to the hAP_ac on eth3 and sniffed the traffic coming and going through.
Maybe somebody here is an expert reading these with wireshark
normal sniff while connecting all three devices:
https://drive.google.com/open?id=1mBjlm . oitWkttSXx

Sniff after one client (192.168.88.103) lost the connection to x.x.x.10 :
https://drive.google.com/open?id=1dUCKK . RMKMOTPBMI

Sniff after one client (192.168.88.101) lost the connection to x.x.x.10:
https://drive.google.com/open?id=1uyE92 . YVd7Qi_gc_

Maybe it’s more an app issue?

192.168.88.10 is the Master-Device
192.168.88.101 Client 1
192.168.88.102 Client 2
192.168.88.103 Client 3

I believe this is some power-saving feature of iOS, because mikrotik cannot possibly know if device has screen on or off.
I don’t understand, how could this be a fault of Mikrotik, when iOS sends a disassoc/deauth frame. Maybe it did not happen with tp-link because tp-link don’t follow standards? (maybe — i cannot be certain but it is one of many possibilities)

Start logging your wireless info and you might figure out what is happening.

I have couple sites with «iphone problem» and some other sites that have apple products, but there is no problem, with the same hardware (wap or wap ac). The problem occurs randomly and present itself as «there is a phone connection to SSID, but there’s no internet». You can see sometimes «disassoc sending station leaving» in log. I use WPA2 only everywhere, DHCP lease is 24 hrs. Tried to disable RSTP, IGMP spoofing etc. Tried basically everything — problem is still there. With cheap soap routers like dlink\asus there is no problem, so it’s pretty hard to explain a customer why mikrotik is better there. Asked Uldis at Moscow MUM — he need specific data to reproduce in lab environment to deal with this stuff and I understand him, but the problem occurs randomly during the day and there’s nothing in log to report to support. And because of that one customer just asks for HP OfficeConnect AP instead of mikrotik, that’s sad.
Also there’s unresolved problem with Android TVs which keep losing lease and connectivity every 5 min.

We stopped using Mikrotik for client wifi several years ago due to connection instability and weak signals vs other brands. We fought with it for a long time. Apple devices are especially troublesome.

We still use Mikrotik routers almost exclusively and Mikrotik radios for point to point wifi links though.

I know it is old topic, but after many hours of struggle with 2 MacBook Pro not being able to get IP, complaining about IP already used by another device (when it’s not) I was able to solve the problem by changing protocol-mode from rstp to stp:

/interface bridge> print
Flags: X — disabled, R — running
0 R name=»bridge1″ mtu=1500 actual-mtu=1500 l2mtu=1526 arp=enabled
arp-timeout=auto mac-address=XX:XX:XX:XX:XX:XX protocol-mode=stp
priority=0x8000 auto-mac=no admin-mac=XX:XX:XX:XX:XX:XX
max-message-age=20s forward-delay=15s transmit-hold-count=6

Once changed, everything works like a charm.

For most if not all small Mikrotik setups no devices need any kind of STP and Wifi Radios certainly don’t if they are just access points for clients. xSTP is only needed in systems where there is the risk of a loop because there are multiple L2 paths in the system. I always set STP to None on my access points as a rule because it’s a redundant option and there’s always a risk of it causing problems.

Before anyone jumps up and down on this STP rule you always have to exercise some judgement. Single ethernet devices like a mAP or wAP are very safe to disable STP on the bridge. Devices like a cAP have some risk if eth1 and eth2 end up being plugged into the same switch, and RBx011 or hAPs always run the risk of a looped back ethernet cable.

I spent quite a bit of time looking at this, and I have found what repeatably works for me with the Apple products. I actually created this account to post this, as I thought it might help someone in the future.

Specifically, I was trying to connect an mAP to the wireless hotspot of an Apple iPhone X, and it just flat out didn’t work with mostly default settings. Two things needed to be done;

1. As mentioned here, RSTP just seems to piss the iPhone off. This one was actually harder for me to find, and I may have never found it without someone here mentioning it. It doesn’t really even make any sense why RSTP would be a problem at all (or related). Probably a really ugly bug/mis-interaction between Apple and Mikrotik’s implementations that makes something hilarious happen from a programmer’s perspective..

2. Turn RX/TX chain 1 off (use only chain 0). This disables some of the MIMO features of 802.11N. You could also try using 802.11B/G Mode instead of 802.11B/G/N but I haven’t tested that.

After doing those two things, I’m able to get 20Mbps through a single radio mAP simultaneously acting as a station and an AP sitting in between the iPhone hotspot. I have a pretty odd use case that makes this desirable, so it might not apply to everyone — but if you’re having trouble with an up to date Apple device (as of April 2020) try turning off the second Mimo chains. They are located in the HT menu under the wlan interface. Also, I had no problems with WMM. In this configuration I was able to pull 20Mbit/sec off the mAP (single 2.4Ghz radio) acting as a station to connect to the iPhone X hotspot, while simultaneously acting as an AP for my laptop. Pretty impressive if you ask me.

A note on Spanning Tree: You can use STP instead of RSTP, but might just as well turn it off when dealing with wireless links. DHCP comes over really slow when you have to go through the STP Blocking->Listening->Learning->Forwarding process, or times out entirely. Not a problem for advanced users or people who read this forum. But not tenable for general user population.
