i have Hotspot wifi create from mikrotik450g
eth1 — wan1 pppoe
eth2 — wan2 static
eth5 — loadbalance + hotspot
i use this script to make loag balance
#ether1=PPPoE
#ether2=192.168.1.123
#ether3=none
#ether4=none
#ether5=22.22.22.1 dhcp range 22.22.22.100-22.22.22.250
#loadbalance PCC 1 PPPoE+1 hotspot static Ratio 1:1

and it go good, no problem
but in last 3 year
my internet begin to fail many time per day, each day fail 3-20 minute
client cannot ping to gateway(ping 33.33.33.1 time out) cannot pin to every Internet, but can ping to another client (example:33.33.33.90) i test to ping NSA310 on the time internetfail it OK not timeout
it will fail in the time most people use
i try to connect mikrotik over 3g to ddns to see — can connect cpu 0-2% ip–hotspot–host empty
now it happen very frequently and long time
please help me
