Hello everyone,

We have using mikrotik all location and we dont want to use phone wireless networking. When they in dhcp we set them 1.1.1.1 address...
Bu i think some user changed mac adress then use the internet. Because only change mac addresses Hostname is same... Like this;



So, i dont want to change wireless password. How can i block this phone?

Won't help you much, especially if the user, which seems to be no noob, finds this theread.

To bad.. so we have to choice 2 way 1 Mac Filtering or change wifi password.. i will use Mac Filtering, we have any guide for it ?

the best solution is always to introduce WPA2 keys. if you leave your AP open like this, anything can happen

you can create a script for get the MAC address from the leases and add it to the access list and block those mac address

Won't help him, as the user changes his MAC. Like normis said, only thing is WPA2 setup or key change...

To block naughty android user with many clonning mac address try to use this script below :
after create this script please running scheduler (every 1 or 5 minutes)

:local hack "android-xxxxxxxxxxxx";    ------------------> fill with hostname to block
:local bnyklease value=[/ip dhcp-server lease find dynamic=yes host-name=$hack];
:foreach looping in=$bnyklease do={
:local ipadd1 value=[/ip dhcp-server lease get $looping value-name=active-address];
/ip firewall filter remove [/ip firewall filter find comment=$hack];
/ip firewall filter add chain=forward action=drop dst-address=$ipadd1 disabled=no comment=$hack;
/ip dhcp-server lease remove [/ip dhcp-server lease find dynamic=yes host-name=$hack];
};

Regards,
Wiwi
