my Wireless problem

hi,

i am new to Mikrotik OS. but, i am learning now.

recently i configured one network

10.20.20.X 255.255.255.0
ISP —E0(450G)E1------------ on 433 created AP-Bridge with (eth1, wlan1 and ip 10.20.21.x as mentioned below)
E2-----------------------------------(433AH)---------------------(TPLINK Wa7510N)---------------
10.20.21.1 10.20.21.2 10.20.21.3 10.20.20.4 192.168.1.x
255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0

from that above if clients connect AP433ah they getting internet
but if clients connect to TPLINK they are not reaching 10.20.21.1, even not pinging, they reaching up to 10.20.21.2 only.
i created hotspot for 10.20.20.x and 10.20.21.x on 450G router board.
what is best configuration to success this network work.
if it possible could you please provide any resource in english only…
thank you,

how about disable hotspot, and see if the client reach net? IT seems like you have an hotspot error.
