Hi,
We have 5 Access points. Some of wireless users are complaining that they are experiencing poor performance at their end of the office.
There's nothing obviously wrong and there's been no changes to AP location, underlying infrastructure etc.
I HAVE read this: https://documentation.meraki.com/MR/Other_Topics/Client_Balancing
We notice that of our access points the distribution is something like this:
1. 45
2. 15
3. 10
4. 15
5. 14
The access points are roughly equidistant....
What I don't understand is, what is causing all of these wifi clients to cluster round AP 1?
Check the minimum bitrate of your SSID.

I'm not sure I understand what you're saying.
We have 2 SSIDs available and these are available on all APs.
Wireless - Access controll, at the end of the site.
He may thinks, the bitrate is configured, for example to 24, so 802.11b devices would not be supported
EDIT: He edited his Post 😉
I still don't understand. The minimum bitrate is the default across all SSIDs. Why would this cause some clients to cluster around one Access Point over another?
Hi Nolan,
Many thanks. This makes much more sense.
The APs are all on the default indoor profiles (the same profile throughout). I'll alter these settings and see how that plays out.
I designed our deployment when we had a different operating structure so it's not that surprising that we're seeing some strange things happening now. It's been a over a year since our last review.
I moved one of our APs closer to AP1 and I've noticed that everything has settled down a bit.
We do see some clients connecting with 2.4 and 5ghz. I'll need to figure out who is connecting to what and why.
So another question. Reading between the lines are you suggesting I switch off Client Balancing?
If you are using voice/video sensitive applications over the wireless, then I would disable as it will most likely cause your fast-roaming to not be so fast, dropping voice calls etc.
To be honest Nolan this isn't a major issue for us. All that might go over WiFi is the occasional Teams/Skype call. Not much more than that.
I would basically just check the power levels, that is usually the reason if an AP is blasting and the others are not. You can change the Indoor Profile for the power level range, in case its still set to default values of 5-30dBm. You might want to close that up to like 11-14dBm for example, or whatever your initial survey results intended for.
TBH I can't remember what the initial survey suggested for power levels, I'll tinker and see what works.
My thoughts are speed issues might be related to the amount of clients on AP1 or the traffic on it. 2 things you could try is turn off AP1 and see if the devices connect to the closest AP and experience the same issue, if they do maybe you need to do a new site survey after hours to better determine your AP locations. The other thing would be to check the traffic on the AP1, if there is high Youtube or streaming video traffice, create some shaping rules or find the problem device and see if you can correct it.
I like @kYutobi initial answer - but I would use a minimum bit rate of 12Mb/s for maximum compatibility.
You could also consider using an "RF Profile". There is a ubilt in one called "Open Office Profile".

I couldn't reboot the AP but I do have a MR18 that can be moved around. I simply moved it closer and then watched to see what would happen. I noticed that the number of clients balanced out much more evenly.
An annoying thing is that Friday is a quiet day in the office. So I'll probably have to sit on this until next week.
