We finished some 700+ routers upgrading to v6.35.2.
Amongst them some 40 AP's and 650 clients connected to these. All AP use NV2.
We now find that whenever an AP is disconnecting clients because some text field has to be changed in the AP's wireless access-list 'comment' field, or because the AP just needed a reboot (for the upgrade) or was temporarily down (to do a 'spectral scan' in the middle of the night) some clients don't come back up anymore.
These clients actually need a power cycle to get connected again.
What we see in difference to pre 6.35.x versions is that when all clients are dropped for whatever reason and are to be associate again to AP the tdma protocol has now problems in connecting them.
Before clients were just connected at random but one after the other. Once a client was associated it stayed connected. Now we see the list of associated clients oscillating. Meaning some clients associate - drop off - associate again - drop off again - and associate. On a 25 cpe AP it now can take a full minute or longer to have all clients back associated where in the past that would not take half that time..... and we now also find that some clients associate and immediate disconnect again not to come back up.... client has to be given a power cycle.....
This is a pain since at times we need to do a spectral scan in the middle of the night and the next morning clients call in because their internet ain't working no more. All it needs is a power cycle but that's should not be the case....
Anybody had seen the same issue?

Re: Anybody had seen the same issue?
Re: ... some clients don't come back up anymore
You may want to search some of my posts. I had a similar problem years ago. My fix was the following:
On all Mikrotiks (APs, clients, - anything Mikrotik), I have a Netwatch pinging my central office (192.0.2.254 - research what this IP is). When Netwatch fails a ping, it then runs a script.
The script does the following:
#1
- Log something that the script was called
- ping 192.0.2.254
- if ping reply to/from 192.0.2.254 is good then log something and counter and exit/abort the script
- if ping reply to/from 192.0.2.254 is bad, then counter=counter+1
- if counter = 30 ( or what ever number you decide on) , then write a log-file stating an auto-reboot was performed (time & date) - then reboot the Mikrotik.
- sleep 10 seconds
- loop back to the "ping 192.0.2.254" section in the script
I use this on every Mikrotik everywhere in my network. Note - with this, clients will survive a spectral-scan and site-surveys.
This procedure will give you (10 seconds * counter) prior to a Mikrotik reboot
I avoid the stock Mikrotik watchdog feature because it is to aggressive at rebooting when there is a delay in the network or the network is congested/saturated.

EDIT - O - I almost forgot a side benefit - if you want to auto-reboot every Mikrotik in your network at the same time - then just turn off your 192.0.2.254 IP address for a few minutes. This works super-great when you want to force some new DHCP options to everything.

Re: Random client disconnects in NV2 ROSv6.35.2
Something else to consider - which is what I also do ...
If you use Cacti (or any other type of SNMP based bandwidth graphing software, - then- also have your Cacti graph the number of connected clients for each WLAN on every AP that you have.
This will allow you to get a quick total connected clients graph per AP WLAN you have in your network.
Also - with Cacti, you can graph your WDS (back-haul) links with information such as signal strength, SNR, tx-rate, rx-rate, frequency, cpu load and temprature. This comes in handy if you ever change a channel, you can see what channels on your links performed the best at what frequency - and you can go back a day or week or month or anytime you want to look at your graphs

Re: Random client disconnects in NV2 ROSv6.35.2
Guys; very welcoming these suggestion. We'll look at the solutions (we already started to use Dude, but still a bit in a learning curve) and see how and if it can benefit us.
But the main problem of the disassociate unit not coming back is not really cured with it. But I am in contact with support about it and honestly, I haven't seen a similar issue the last days. But then again, I didn't switch an AP off for whatever reason the last days....
Anyway, together with Mt with hope to find a cure....
But as said, suggestions for network monitoring and alerts etc. are very much welcomed.

Re: Random client disconnects in NV2 ROSv6.35.2
Great post, Tomj!
Did you anycast this 192.0.2.254 for increased robustness? It sure would be catastrophic if that one host fails / gets isolated and causes your entire operation to take a power nap. Perhaps you have several such ping targets and simplified it for the example, but I felt like this nuance should be pointed out in case anyone else deploys such a solution without realizing this could happen. Or perhaps that IP is configured on your core router so if it's down, the whole kit and kaboodle is down anyway so who cares if CPEs start rebooting like lemmings off a cliff?O - I almost forgot a side benefit - if you want to auto-reboot every Mikrotik in your network at the same time - then just turn off your 192.0.2.254 IP address for a few minutes.

If that one hosts fails (my 192.0.2.254), then yes I have a serious network problem. That IP address ( 192.0.2.254 ) is a local IP address on a loopback interface of my core router. If that goes down - then I truly have lost all network access to everything everywhere to/from Internet and to/from all client customers.
Another trick re the auto-reboot info - which I also do sometimes:
Have all Mikrotik client devices test to 192.0.2.254
Have all core routers & APs & backhauls test to 192.0.2.253
This way you can easily only reboot customers or only reboot your network devices - or both at the same time.
Also you can setup 192.0.2.x zones - where clients in different areas test to a specific IP 192.0.2.z IP address - thus allowing you to auto-reboot zones instead of everything at the same time.
The IP address 192.0.2.254 is does not route through the Internet - it is intended (kinda like 192.168.x.x ) to be a test network. Thus 192.0.2.x/24 is safe to use because nobody on the Internet can talk to it - only your networks can talk to it.
re: anycast
I treat it just like a normal live IP address.
Thank you for you positive reply
North Idaho Tom Jones
EDIT - added the following - also - on my client devices - I also log to a Mikrotik file the frequency of the AP and the signal strength and connect rate the client sees when it connects. If you have multiple APs covering a sector - then you can look at the client log for what happened - last auto reboot - what IP it connected to when the client restarted and what the signal strength was.
North Idaho Tom Jones
Another EDIT - I am looking to enhance my scripts with some extra code that prior to an auto-reboot - the Mikrotik will perform a scan and a frequency usage into a file in the log. Then I would have the ability to look any clinet and see what the wireless conditions are like at the remote customer location.

Give this a try -

Re: Random client disconnects in NV2 ROSv6.35.2
When testing it - if you look at your logs - you can see that a client is going to reboot in 15 seconds prior to the actual reboot.
This gives you time to abort/stop the script/job if you do not want the Mikrotik to actually reboot while you are working on it.
To disable it - just disable the netwatch - then it will no longer run. This is handy sometimes.
I wish Mikrotik would modify their watchdog to perform something more friendly like this. It would save on all kinds of false/un-needed reboots.
