The Contention Slots setting still matters for your transmit/receive timing for the downlink/uplink percentage and switchover time, whether AutoContention is enabled or disabled. So if you are going to switch Contention Slots setting make sure you run the Frame Calculator tool to make sure your Tx/Rx time aren't over lapping with any other APs.
@Charlie WOW, really? I had no idea that these had to be set correctly. After multiple talks about auto contention with Cambium engineers, troubleshooting it, working on beta, etc. this was never mentioned to me and I was lead to believe that this setting was no longer used. Time to audit all our AP's contention slot numbers I guess :-/
Eric, yes, really. :-/
If we had no longer used the Contention Slots configuration to calculation the downlink/uplink transition, then enabling/disabling this setting on one AP on a single AP could cause self interference issues with the other APs that were already aligned. So we decided it was best to leave the Frame Configuration the same whether the setting is enabled or disabled, especially because there is no reboot required to enable/disable AutoContention.
You're right that it isn't used in the implementation of AutoContention, but the setting still affects how many uplink slots are configured.
As long as you did the same thing on all your APs, hopefully you should be fine. Sorry if we did not make this clear enough. The whole point to AutoContention is it doesn't matter what you have Contention Slots set to, it will do it's best. Except it absolutely does matter for Frame Configuration, so just leave alone unless you are ready to change for all your APs at that site.
So it doesn't have to be "correctly" (as there is no "correct" with AutoContention enabled) just whatever you want it for downlink/uplink percentage.
