Wireless clients keep getting disconnected/reconnected

RouterOS Wireless Networking
1

Hello!

I have problem with RB2011UiAS-2HnD v6.34.5 (was downgraded from v6.64.6 that has similar problem).

Is it plain hardware fault (wireless module)?

Wireless clients keep getting disconnected, few seconds after getting connection. I have tested with completely open wireless (no auth) and there is same problem, so it is not wrong auth. I have enclosed excerpt from log:

“not in local ACL” should give you a clue

3

I have noticed that problem might be in authentication mode, i have created/tested several security profiles with WPA2 PSK, different keys but when it is on, clients get disconnected. It is not wrong setup since it is tested several times and sometimes clients get connected for like 5 minutes but when they start to use connection, create traffic, they get disconnected…

There is no ACL setup on wireless interface…

4

i’ve got same problem for log time, im going to show you something, if you fix it up, let me know

http://wiki.mikrotik.com/wiki/Manual:Wireless_Debug_Logs

5

Have you tried to extend group key update interval to 1hour?

6

what’s that?

7

Something that might help you.

8

copy that, so how can we set up that?

Thanks

9

It is a parameter of the security profile.

10

i’ve already did,and i let you know after couple of days. Can i ask you which one are you recommending about "Authentication types (im using WPA PSK and WPA2 PSK ) and "Unicast Ciphers (tkip) snd also Group Ciphers (tkip). Just one think Management Protection (allowes)

Thanks

11

Just i let you know, i’ve cheange that parametar, but again i’ve got same problem:

wireless,info xx:xx:xx:xx:xx:xx@wlan_guest: disconnected, ok
07:10:43 wireless,debug wlan_guestxx:xx:xx:xx:xx:x not in local ACL, by default

12

Use wpa2 aes only.

13

Are you sure that WiFi credentials are correct for all users’ devices ?
The best way is to forgot WiFi lan at each device which has problems and recreate connection.

14

That is also my advice. Remove all security profiles, all SSID’s etc…

Recreate the new connection (heck, you can even use the Quickset to do this). Use ONLY WPA2-AES. All “modern” equipment can do WPA2.

jarda im having problem again…

16

Change from TKIP to AES

17

following that i saw that, whan im connecting mobile phone at that time i’ve have that problem

wireless,debug wlan2: 94:CE:2C:2C:96:A9 attempts to associate
12:27:32 wireless,debug wlan2: 94:CE:2C:2C:96:A9 not in local ACL, by default accept

and also

Thear mac address from phone

Thanks

18

What about with aes only, without tkip. I told you that already. And you can disable management protection.

19

much better, still i can see same problem, at the past was terrible

Thanks

Sorry for delayed answer but, tried factory defaulting device and there were still problems so in the end we bought new device and it solved problems. Although there was issue in that area has lots of neighbouring APs so problems might have gone with transferring more users to 5GHz.

Kind regards
