"Data from unknown device xx:xx:xx:xx:xx:xx, sent deauth" ?

Mon Mar 05, 2012 9:04 pm

Hi,

I have RB 493G + R52Hn (+ 8dBi antenna). Wireless is in "AP Bridge" mode. There are 6 wireless clients in the house (2x Notebook, 1x MAC, 3x Smartphone). Encryption is WPA2 PSK (aes/ccm). All of the devices are in the AccessList. Problem is with one Smartphone (HTC Desire Z, AndroidOS). Mikrotik LOG is spammed by line "Data from unknown device xx:xx:xx:xx:xx:xx, sent deauth" (the MAC belongs to the smartphone). Another phone (Samsung Galaxy, also AndroidOS) does not have this problem at all.

Anyone know how to fix the problem?

18:30:16 wireless,info WLAN: data from unknown device XX:XX:XX:XX:XX:XX, sent deauth
=== Another 70 lines with the same messahe, every 5sec===

when you rip out the mac's its hard to tell you what the issues is, rather just make it dev1mac,dev2mac,dev3 if you want to keep animosity,

country=no_country_set
default-authentication=no

Firstly if an device is not in the ACL then it wont be accepted, but you do need to be notified in the log file?

I am unsure as to what you want to see in the log file that will be more important, but you can set up an remote log as well with a filter, the log manual will be able to assist u as well to not see things u don't want to see?

That MAC belongs to one of the known device (phone HTC Desire Z - Android) and it is in the AccessList like the rest of the wireless devices, but only thisone causing the problem.
The device is accepted and connected successfully, but after coupple of minutes, it gets disconnected and then the message start appearing in the logfile. (The smartphone is on the same place, 4meters from the AP, so it does not left range of the AP.)

I found some information that the smartphone maybe using power save wifi mode, but with WMM enabled it shouldn't be a problem ...

try default autenticate = yes. If it works, then u know there is something about phone or the mac provided in accesslist

This is not a solution, this is "workaround" which will also remove other system messages which i would like to have in the log.

The thing is, the device will enable power safe mode after a while, anyway the wireless should stay connected (as it was before with another router), unfortunatelly looks like Mikrotik will not receive response to this:
disconnect-timeout (time [0s..15s]; Default: 3s) .... This interval is measured from third sending failure on the lowest data rate. At this point 3 * (hw-retries + 1) frame transmits on the lowest data rate had failed. During disconnect-timeout packet transmission will be retried with on-fail-retry-time interval. If no frame can be transmitted successfully during diconnect-timeout, connection is closed, and this event is logged as "extensive data loss". Successful frame transmission resets this timer.
(I've set the timeout to 15sec, but it did not help)

So, Mikrotik is trying to deauth that device, but the device will not deauth, and that is the reason why the LOGfile is spammed over and over by the message.
22:45:59 wireless,info WLAN: data from unknown device <CLIENT_MAC_1>, sent deauth
22:45:59 wireless,info WLAN: data from unknown device <CLIENT_MAC_1>, sent deauth
22:45:59 wireless,info WLAN: data from unknown device <CLIENT_MAC_1>, sent deauth
After that, when i unlock the device and try to access something on network, wireless connection will drop for few sec and then it reconnect (i have autoconenct to that Wireless network) and reassociate on Mikrotik, then the connection is fine, until the phone fall into power saving mode again ...
22:46:14 wireless,debug WLAN: <CLIENT_MAC_1> attempts to associate
22:46:14 wireless,debug WLAN: <CLIENT_MAC_1> in local ACL, accept
22:46:14 wireless,info <CLIENT_MAC_1>@WLAN: connected
22:46:14 dhcp,info dhcp1 deassigned 192.168.X.XX from <CLIENT_MAC_1>
22:46:14 dhcp,info dhcp1 assigned 192.168.X.XX to <CLIENT_MAC_1>
Yes, i can disable the saving mode for wireless, but this will drastically decrease the battery life (the phone will die in 3-5h), which is not acceptable at all.


And again, i did not had this kind of problems with another Wireless router (ASUS, Linksys), i hat wifi enabled on that device 24/7 and without any problems.

So, the question is, where the problem is. Is it a RouterOS bug or Mikrotik is tooo sophisticated? And the most important thing is ... "how to fix this" ? Maybe some way how to exclude some device from that 15sec checking, or at least way how to exclude exact line from logfile. But the proper fix would be much appreciated, IF the problem is in Mikrotik (i did not find any arcticle, discussion or comment obout this :( )

Thanks,

Stun

Had the same problem. Someone was using an Ubiquiti client to try to connect. I think the problem was that he had not setup the password. Plus my MT was restarting the whole time. Never found the real problem; just asked the person to turn off the Ubiquiti radio.

I had the same problem with a Samsung (android) phone. Rebooting the phone solved this issue. The AP stopped functioning for all the other clients while this DEAUTH flood was going on.

I saw a similar flooding of messages with a Nook Color.

I'd argue that the logging for that message shouldn't be at "info" level but more like debug.

+1 for this problem, Samsung Galaxy S2 (I have two devices, problem happens with both)

It is really annoying and it is impossible to keep the wifi while device is in idle mode, and it EAT all my mobile data plan.

Was on 5.2x, upgraded to 6rc7, same problem

My apologies for the thread necromancy here, but rather than start a whole new post about this I'd just like to add that I'm having the exact same problem, also caused by a Samsung Galaxy S2 on my wireless network.

I absolutely love my MikroTik router, but this one "feature" is really getting annoying. As a previous poster said, I did not have this issue with my old WRT54GL running DD-WRT or the piece of junk Asus router I had after that.

Whenever the deauth flood happens it absolutely kills all wireless access. Everything gets thrown off the WLAN and cannot connect to it until the offending device is rebooted. If I connect to the router via ethernet and look at the log, it is getting absolutely hammered with deauth messages related to the MAC of the Galaxy S2. I figure this is probably an Android bug related to the S2 but I would hope the router would handle this better.

IS there any fix for this? (Yes, rebooting the phone makes it stop but that's not a fix!)

All right...anyone? No one? This is a common problem and we get complete silence. I'm sick of my Galaxy S2 completely knocking out my wireless. I've done a google search and this is a very common problem and I have yet to see any kind of an answer or solution. There is no reason why a buggy Galaxy S2 should knock out a router for hours on end with "deauth" errors. Even my piece of junk Asus router didn't do this.

Is anyone out there listening?

Maybe a more recent thread will yield some answers, or at least posting there might draw more attention to the problem.

I have the same issue here. RB951-2n
Already updated to version 5.24 and the problem not solved either.

I keep getting this log continuosly every several seconds or minutes.
wlan1 : data from unknown device (dev1mac), sent deauth.
(dev1mac) @wlan1 : connected
(dev1mac) @wlan1 : disconnected extensive data loss.
wlan1 : data from unknown device (dev1mac), sent deauth.
wlan1 : data from unknown device (dev1mac), sent deauth.
(dev1mac) @wlan1 : connected
wlan1 : data from unknown device (dev2mac), sent deauth.
(dev2mac) @wlan1 : connected

I only use 2 client. 1 is Galaxy Phone and 1 is PC.
This deauth thing seems to be more often occured on my Galaxy phone device.
I already try various difference configuration in wireless advance mode.
hw protection mode, hw adaptive noise immunity, hw retries, preamble mode, WMM, disconnect timeout, bridging, and everything else in there but still no luck.


Anyone already got the resolve or we need to wait for the next version?

Looks like the issue may be related to the DTIM interval on the AP. Unfortunately there's no way to configure DTIM interval on Mikrotik yet.

Maybe try setting "Multicast Helper" to full? Also try enabling higher basic-rates.

Hi all, just a small offtopic.

I moved out from old flat and i sold Mikrotik to my friend since i don't need that model anymore.

I bought RB450G instead plus cheap "N" AP which is connected via LAN port to Mikrotik (so no routing on AP, everything is handled by RB).

No problem with the same mobile device at all. Power Save mode works flawlessly, no disconnecting, no freezing/hanging.

So ... it looks like "less is more" :lol:

Hello

Most likely this happend when you have connected TP-Link device to the AP, just try to find this device and upgrade to latest available firmware. I'm pretty sure that this problem will disappear

The error "data from unknown device" happens because of the previous problem above - "disconnected, extensive data loss ". This message means that the AP could not contact the phone, and disconnected it. This could be caused by some power saving feature in the phone. If possible, turn off that power saving feature.

You can also increase HWretries setting to 15 and see if that helps. Also check if you have not disabled any data rates. And then check if the phone is simply not too far away.

I had the same problem and spent few hours trying to find mistake in wireless configuration.
The trouble was related with DHCP server. DHCP was configured to lease IP address only for Ethernet interfaces!
Everything went back to normal as soon as I switched the DHCP server on a bridge containing both Ethernet and WLAN ports. :)

Hi,
I'm sure you already know about this, but just for the record, I post it here.

<DEV>: data from unknown device <MAC>, sent deauth [(XXX events suppressed, YYY deauths suppressed)]

Data frame from unknown device (read - not registered to this AP) with mac address <MAC> received, AP sent deauthentication frame to it (as per 802.11). XXX is number of events that are not logged so that the log does not become too large (logs are limited to 1 entry per 5s after first 5 entries), YYY is the number of deauthentication frames that should have been sent, but were not sent, so that resources are not wasted sending too many deauthentication frames (only 10 deauth frames per second are allowed).

The likely cause of such a message is that the Station previously connected to the AP, which does not yet know it has been dropped from AP registration table, sending data to AP. Deauthentication message tells the Station that it is no longer connected.

I don't know why, but it seems that increasing the DHCP lease time reducing the problem a lot.

the received deauth message disappeared, but i still face sudden disconnect/connect every few hours.

Hello, have the same problem. with an hAP Lite on both wifi interfaces... most of the problems was with SAMSUNG Android phones...

In Atheros 9800 and Atheros 9300 have a lot of log messages saying
"Data from unknown device xx:xx:xx:xx:xx:xx, sent deauth"

Now running 6.37rc26...

Does anyone have an idea how to solve this?

Still the case with 6.38rc19. It seems like nobody has a Samsung phone @Mikrotik...

Trying to set DHCP least time > Group Key Update = 1h in a last desperate attempt to reduce problem occurrence.

Made a bunch of changes following each trick and advise related to the topic.
Connection has been stable for several hours now. Big relief. :D

I cannot narrow down to the actual enabler as I do not want to bother anymore the customer, but here is the actual config in case it helps others.
/interface wireless
set [ find default-name=wlan1 ] band=2ghz-g/n bridge-mode=disabled \
    channel-width=20/40mhz-Ce country=switzerland disabled=no distance=\
    indoors frequency-mode=regulatory-domain guard-interval=long hw-retries=\
    15 keepalive-frames=disabled mode=ap-bridge security-profile=XXX ssid=\
    XXX wireless-protocol=802.11 wmm-support=enabled wps-mode=disabled

in my case solution for the same problem (device - Xiaomi Mi Box Enhaced 3) was DHCP Lease Time - I just increased time from 10 min to 1 day.
Now every day my tv box need to be restarted but wireless connection works fine!

SOLUTION IS:

If you bridged Eth and Wlan interface together, check in IP->Address that you assign local ip address on bridge interface, not only on Eth interface...this was solve my problem. :)

Good luck! :)

This problem can be fixed with enabling the option Default Authenticate in the wireless interface options
