Strange reassoc problem

RouterOS Wireless Networking

Recently I’ve encountered kind of strange problem with unnecessary client reassociation, which previously hadn’t happend. There where no physical change in hardware configuration, just some software upgrades..

Log in AP says:

12:17:56 wireless,debug wlan5: 00:15:6D:C1:AA:AA attempts to associate
12:17:56 wireless,info 00:15:6D:C1:AA:AA@wlan5: reassociating

Log in CPE says:

12:17:02 wireless,info 00:15:6D:64:BB:BB@wlan1: lost connection, extensive data loss
12:17:04 wireless,info 00:15:6D:64:BB:BB@wlan1 established connection on 5805, SSID kvartalas-5p

12:17:56 wireless,info 00:15:6D:64:BB:BB@wlan1 established connection on 5805, SSID kvartalas-5p

Signals are -59/-56, SNR 45

I’ve noticed that this could be related with wireless-test package. All this started when wireless-test package was enabled. So to be sure, I’ve switched to wireless (not test) package, seems this has some effect, everything works fine.

Can someone please explain if there are any more differences between wireless and wireless-test packages despite those mentioned in http://wiki.mikrotik.com/wiki/Wireless_Development ?

Reason I decided to use wireless-test package was to implement Management Frame Protection.

I would investigate what is the strength of signal with scan or snooper from the client side and see maybe there is some noise

This is clearly wireless-test package related problem. While wireless-test package was in use, stations kept reassociating over and over again every few seconds, sometimes they lasted for a minute. And now, two days have passed since I switched to wireless package. All CPE’s have now almost 3 days wireless uptime.. Don’t know if I need to dig more.

Hi. I switched to wireless (not wireless-test) package in AP only (no need to do it on CPEs). I have 14 days of wireless uptime since.

Try to check what does the log on CPEs say.. Sometimes it helps. But if you use ordinary wireless package then it’s another problem. I think you’re aware what ‘extensive data loss’ means (check sticky posts in this forum)..
