High CPU Load in HAP AC Lite

Mon May 06, 2024 12:56 pm

Hello,

Need advice in here about my mikrotik.
My board is Hap ac lite.
Only use for wifi and eoip that is connect with hap ac2 in same subnet.
I used eoip to connect tv channel that is connected in hap ac2
wifi is manage by capsman

but when the traffic hit more than 60mbps it will cause high cpu then the traffic become slow down and the tv channel will lagging.
routing and others are manage in hap ac2

why is only for eoip and wifi can cause high usage in cpu?
