Orbi 771 lags every 60 minutes exactly

I was able to feed these debug logs into Claude and it found the following, in case it's useful:

Root Cause: Hourly Backhaul Channel Scan (BkScanCron)

Your Orbi 771 is running a mesh backhaul scan every 60 minutes, exactly on the hour. This is configured in the firmware as:

ezmesh.MultiAP.BkScanCron='0 * * * *'

ezmesh.MultiAP.EnableCronBasedBkScan='0'

The EnableCronBasedBkScan='0' setting is supposed to disable this, but the logs prove it's not working. The scan fires anyway.

What happens during the scan (confirmed in emt_dbg_log):

Every hour, a cascade of events hits the wireless subsystem. The logs show:

Invalid channel change events — the backhaul radio briefly goes off-channel to evaluate alternatives

Stats collection disabled for every connected device simultaneously — the log shows "Cannot sample STA stats for [every client MAC] as stats collection is not enabled" firing all at once, which only happens during a scan

Messages from unknown BSS — the satellite (your RBE770 at 192.xxx.x.xx) temporarily becomes unrecognized as the backhaul link is disrupted

Band steering decisions triggered en masse at the exact same moment

This creates a ~30-second window where the backhaul between your router and satellite is degraded or disrupted, which explains the choppy gaming experience you're seeing.

Why your channel pin didn't fix it: Pinning channels only controls the fronthaul (your devices' connection to the router). The backhaul scan is evaluating the satellite's connection to the router, which uses a separate 6GHz backhaul radio — so the channel pinning has no effect.
