Hello guys,

There is a router MT, with a hotspot page.
when MT is connected to Modem by cable from port 1 in order to connect to net,
it causes, connection to net have problem, modem doesn't work properly.
Modem normally sends data to the nearest router now the nearest router is MT and no data send to net.

If it is not clear enough, ask to explain more to clear the issue.

regards.

Can you give some more details as the diagram and also the connectivity status from mikrotik to internet ?

it is solved.
The connection to net is available via MT router that is know on Bridge mode.
but the modem ADSL doesn't reply to users any more.
