Hello,
I want to solve a simple task: Connect wirelessly one device via Ethernet port as the device does not have a Wi-Fi interface onboard using MAP lite.
Here is my config

# jan/02/1970 00:05:20 by RouterOS 6.46.2
# software id = LSII-8EHA
#
# model = RBmAPL-2nD
# serial number = xxxxxx
/interface bridge
add name=bridge1
/interface wireless
set [ find default-name=wlan1 ] band=2ghz-b/g/n disabled=no frequency=2422 \
mode=station-pseudobridge ssid=xxxxxx
/interface wireless security-profiles
set [ find default=yes ] authentication-types=\
wpa-psk,wpa2-psk,wpa-eap,wpa2-eap mode=dynamic-keys supplicant-identity=\
MikroTik wpa-pre-shared-key=xxxxxxxx wpa2-pre-shared-key=xxxxxxx
/ip hotspot profile
set [ find default=yes ] html-directory=flash/hotspot
/interface bridge port
add bridge=bridge1 interface=wlan1
add bridge=bridge1 interface=ether1

when I enable bridge between Ethernet port and wireless connection, I can't connect to master AP and even ping it inside master LAN. PC, connected to LAN port doesn't get IP address from master network. Same story with another master AP in another LAN.
Any ideas?
What could be wrong?

Don't understand your security profile. PSK + EAP ???? .
Does your mAP connect to wifi ? (in wireless : registration tab)

You may have to set the STP in the bridge on "none", because of timing issues with DHCP when the WLAN1 connects.

Your settings seems incomplete to me. Can you past the complete one, specially with LAN/WAN interface list definition.

Do you want to make a bridge setup: your "ethernet client" will get an IP directly from your main Wifi AP
and map lite acts just as a "switch" ?

Have you tried "quickset" with "CPE" mode?

please advise how I can post complete settings.
Yes, correct, I need a bridge setup, "ethernet client" should get IP from the main network.
I have tried CPE mode from quick setup, it works in the same way - main AP stops work when I enable bridge.

Yes, mAP connects to Wi-Fi successfully, but main AP stops to work when I enable bridge.

Can you explain what is behind "main AP stops work when I enable bridge" ?
"Stops working" ? In what way? You can't connect anymore with another client? You lose connection from another client? Or what makes you decide it stops working.
You already indicated : "network storm" in the title. Indicators go to 100%?

As long as you do not get an IP address then IP based connection will not be possible (indication is you get a 169.254.x.x address )
What if you give the client a manual address in the proper range of your main AP.?

Reducing the complexity would be to remove WLAN1 from the bridge and use "station" mode , and give ether1 a DHCP client. Does it obtain an IP address then ?

Full config comes with: "export hide-sensitive" in new terminal, or in a telnet or ssh session., what you already did before, but did cut the info too early (parts are missing).
