Mikrotik stops being accessible until reboot

LTG · Wed Aug 03, 2022 10:37 am

Hi, i am new to this forum and mikrotiks
I recently got a used mikrotik hap light and after a few hours it will stop being accessible (cant see it in winbox and cant ping it) from the "wan" port as well as the VMs that are behind it. If i use a computer that is directly connected to it i can access the mikrotik as well as the internet normally. When i reboot it starts working again.

How i set it up

Firstly i reset the device and selected no default configuration

Used the quick set option (CPE) and connected to the ISP modem wirelessly

Selected Bridge mode and set static ip

Updated RouterOS to latest version

My network setup
I used the hap light to connect wirelessly to my ISP modem (5-10 meters away with just a plasterboard wall in between, signal reception is good) and provide network to a server (R710 running multiple VMs), a laptop and a switch (managed switch but without dhcp and currently nothing connected on it).

My config

I have removed only the wifi password.
I apologise if the formating or grammar is wrong, any help is appreciated.
Thank you in advance

If the config, except the password, and the censored serial number, is exacly that, paste this on terminal:

/interface bridge
set bridge1 name=bridge protocol-mode=none
/interface wireless
set [ find default-name=wlan1 ] band=2ghz-g/n wireless-protocol=802.11
/interface wireless security-profiles
set [ find default=yes ] wpa-pre-shared-key=""
/interface list member
remove [find]
/interface list
remove [find]
/ip address
set [find where address="192.168.1.100/24"] interface=bridge

If you do not use MikroTik devices on both side, this can cause problems, because station-pseudobridge do not work the same on all productors.
/interface wireless
set [ find default-name=wlan1 ] mode=station-pseudobridge

Whit this you want filter dhcp because you have two dhcp server on same network???
/interface bridge filter
add action=drop chain=input dst-port=68 in-interface=!wlan1 ip-protocol=udp mac-protocol=ip

You have problem every x minutes, where x minutes are the dhcp lease time of main router?
If yes, probably all stop working when dhcp lease expire???

I tried applying the suggested commands, i added the wifi password in the wpa-pre-shared-key field but it would not connect to the wifi afterwards so i restored it to the previous settings. What am i doing wrong ? i copy pasted the commands one by one in the terminal, should i reset first ?

Thanks

edit: just noticed the second response, i only have 1 dhcp server from my isp modem/router i checked the lease time it is set to 1 day. The issue seems to occur every few hours.
