I will keep it simple with my first question but I’m sure this will evolve into a much larger conversation:
If my highest subscription level as an ISP is 7mb, what should my highest date rate be on my AP?
Key point to note here is that no client will need more than 7mb of bandwidth.

I would say set it as high as possible while retaining a stable link.
What i do is set is set the minimum data rate to prevent rate flapping.
on 5ghz a i set 18Mbps Basic rate and supported 18Mbps + all the other after it.
If it starts giving issues drop the max limit by 1 or the min limit.
Same applies wil 5ghz N, 5Ghz AC is an entire different problem when it comes to data rates
What about the HT MCS?
If I don’t need more than 7mb on any given client, doesn’t it make sense to deselect all of the MCS options?
i use this setting, i only use N mode with NV2
How many Clients on that AP?
What’s the max bandwidth per client?
Are your wireless clients allowed to talk to each other?
On a second thought, I wouldn’t recommend disabling the higher data rates. Using lower data rates means using more air time, which in turn means more competition for air time with neighbor networks and worse user experience for both your and your neighbors’ networks. This considerations, however, might not apply to PtP links.
I’m not concerned bandwidth so much as the clients are reaching the speeds required for my network.
I’m mainly concerned with latency and overall jitter. I’m thinking the culprits are data-rate flapping and clients with low signal strength (>70dB). The subject of data-rates was brought up because I see this as the easiest fix.
I will post my latency and jitter over a two hour period during peak time along with client count and throughput at the AP.
It’s not really bad, just looking for ways to tweak and optimize. What I’m experiencing might be perfectly normal.

You ofer 7Mbit Plans?
OK
But the way to limit user data rate is not to limit AP rates…
latency and jitter is more a think with interference…
Oh no, I’m limiting with queues at the branch router.
Im not asking how to limit data rates or bandwidth. I’m asking how to optimize latency.

Nv2 latency?
Post your config
Here is my config:
At present 6 Mbps is used for NV2 Management Protocol, my question is what impact this has on overall wireless throughput and AP optimizing?

Reviving an old thread.
New question: What affect does lower data-rates have on the overall throughput performance of an PtMP access point (i.e. using just 24mbps and 36mbps rates without any MCS being selected)?
I ask because I recently came to the realization that if none of my end-points need more than 10mbps, then there is no need for a configuration that allows for connection higher than the intended speeds. This also keeps latency down; I like to use the analogy of “shifting gears” in a vehicle frequently.
However, my question is now, does this make the PtMP AP have less overall throughput (collectively with ~30 clients connected)?
If you limit the AP to lets say, MCS 1 which gives you 13Mbps @ 20MHz, this is the air rate you are going to be sharing with eveyone! 13Mbps for x amount of clients you have on the AP. Leave it at auto if you don’t know what you’re doing or limit it to the MCS rate which gives you the best overall CCQ. HereIi limit my APs to MCS 12 because it gives me the speed I need for my clients while keeping a good average CCQ.
By “Air rate I’m going to be sharing with every” do you mean in this scenario of 13Mbps that my max throughput (all clients combined) will be 13Mbps?
Here’s a better example:
Lets say I use a datarate/mcs configuration that allows for up to 24mbps. Can the AP pass traffic for 5 clients maxing out that rate (i.e. 24mbps*5=120mbps)? OR are you saying my overall throughput cap for the AP is now 24mbps?
In your scenario, 24Mbps / 5 = Shared bandwidth. in Wireless (802.11, NV2, Nstream, AIRMAX…) the AP is always sharing bandwidth. The actual AP data rate is the amount of available bandwitdh for everyone connected to it, simple as that!
Remember that we’re talking about air rate, the wi-fi protocol eats up almost half of the available bandwidth for it to work + other stuff you end up with half of the actual data rate.
