Wireless problem with Apple devices

RouterOS Wireless Networking
1

I bought a new device and notice the outages and subsequent connection within 5 sec. It happens several times a day. I used Android and Win before and I didn’t have such problems.

What is in the wifi registration, and what is in the log? You might want to add system->logging->topic=wireless for more detailed information.
Has the DHCP lease been given out (bound)?

3

In the log is (for example):



I don’t know if the connection was lost at this time, but in the first picture there are outages around 23:00, when the device is in static place. The signal is weak, but outages also occur near the router.

I do not understand the second question. I am a beginner :slight_smile:

4

Apple devices don’t like symbols in the password. Change the wifi password to just letters and numbers and it should work fine.

5

Thanks, I try it :slight_smile:

6

the problem still persists

AFAIK this is normal behavior from apple - they disconnect to save the power, when display is off (or device is locked) and they connect on regular basis to allow apps get updates/messages/notifications
https://discussions.apple.com/thread/250285673
https://apple.stackexchange.com/questions/218354/how-to-prevent-iphone-from-dropping-wifi-connection-when-it-goes-to-sleep
and many many others… if you google “apple wifi disconnects with display off” you will see how widespread it is.

8

But MacBook Pro is disconnecting with display ON :slight_smile:. iPhone only with display OFF.

9

About the second question (DHCP) : look in the DHCP server on the MKT, i the tab Leases. Has there been an IP address given out (bound) to the Aplle device, or is it just “offered” and not “bound”?


In the configuration:. IP address should be given to the bridge1 interface (master) , not to ether2 (slave)

/ip address
add address=192.168.1.1/24 interface=ether2 network=192.168.1.0

make it

/ip address
add address=192.168.1.1/24 interface=bridge1 network=192.168.1.0

10

I repaired it :slight_smile:. And (MikroTik says BOUND):

11

I suggest you to increase “Lease time” to 30
Apple devices doesn’t like low “Lease time”.
PS. For home i make 3 days

12

I try it :slight_smile:.

13

one more recommendation

/interface wireless set preamble-mode=long

14

Some more recommendations:

  • use hide-sensitive when exporting
  • place configs in code tags: [ code] and [ /code] (without the space)
  • only use WPA2/AES
15

I set the lease time to higher value and now is all ok.

16

What effect does this have for connecting to apple devices?
What effect does this have for other devices that are not apple?

(PS My issues also seemed to be lease and DNS related, changed to PEER DNS and so far resolved but too early to tell since it seems spurious without rhyme or reason).
