How does channel width affect timing?

I don’t know specifically how.
But here’s frame calculator result for 30mhz, 75%, 10 miles, 8 control slots:
AP Antenna Transmit End : 34161, 3.416176 ms
AP Antenna Receive Start : 36530, 3.653073 ms
AP Antenna Receive End : 49175
Now same at 5mhz:
AP Antenna Transmit End : 27916, 2.791688
In case it’s not obvious, the 5mhz “receive start” happens before the 30mhz
“transmit end”. So the 30mhz AP is going to cause uplink interference on the
5mhz AP…..assuming there’s channel overlap.

Why 8 control slots? Cambium recommends starting with 8 for over 150 subs
per sector which seems like an insane number of subs on anything but M.

1. Some AP’s have few SM’s, some have many SM’s. I need timing to match
either way.
2. Contention over control slots could cause jitter. I don’t want jitter,
and there’s not that much cost to having a few more control slots….see point 3.
3. There’s only a 4% difference between 1
The value to watch for that is Ctl Req Success. OID

Even with 8 control slots I see that fall to 70% or so at peak times on the
busier AP’s. That means some of the SM’s were not able to request an upload
timeslot, which means whatever they’re wanting to upload
If a unifi network is already managed in a unifi server and then someone
comes along and plugs in a cloud key on the LAN, can you then just adopt all
the stuff into the cloud key? Or do you have to "forget" them on the server
first?

We have one of the new Mikrotik CCR2216-1G-12XS-2XQ routers running RouterOS

You can either forget them and re-adopt on the cloud key or you can back up

Double check the gateway and subnet on the server.

Very minimal, really just basic input rules, nothing that would block the IP
addresses from getting through. No NAT or Mangle rules on this router.

Input/output aren't relevant for forward traffic.
Are your subnets right everywhere?

To verify that, drop the firewall and then test again.
If its firewall related it will start working.

If this is a Mikrotik switch, reboot it before you waste a lot of time.
I've seen weird stuff too many times. I had a CRS317 the other day where we
got 98% packet loss to one specific host. Watching the switch hosts table it
seemed like it kept changing it's mind as to which interface that MA
You have the proper name…..Ctl Req Success was how I labeled my chart.
In any case, I’m reasonably sure it’s showing the % of upload bandwidth
requests which were handled successfully. Those requests come in during the
control slot using a contention based method. So it’s possible to have
That is the export of the entire firewall on that router, there are no forward,
nat or mangle rules, therefore there shouldn't be anything keeping the data
from getting to/from anything, let alone blocking all but one IP address in the

It's a /29 block, ip is x.x.x.x/29 on the router
Rebooted both the router and the switch, no joy, issue persists.

Yup, x.x.x.x/29 in the same range.

When I connected my laptop, I had internet, which is also weird since it was
unreachable by ping. But yes I statically assigned the IP to the laptop with
the correct IP, gateway and subnet.

Yes, but it ends with an INPUT "drop all" entry.
Agree it does not "appear" to be anything in the firewall,
but only takes a few seconds to test and prove one
way or the other.

Fair enough, but traffic through the router would be forward chain. Input
chain only affects traffic destined for the router itself.
I agree it's an easy thing to check.

If it's not something obvious with routing or firewall, my next step would
be to look at torch and/or packet captures to narrow it down.
