Hi.
I have one dump problem setting bridge mode between two different routers. The router that i want to change is in upper floor ( siemens ) and the main router is downstairs ( Thompson ).
The original siemens router has updated firmware and some open source firewall, that i can not access. So instead of this ( and to keep the original router settings ) i want to change the router with same one (with factory settings ). I have found one in the basement and its totally the same model.
So, i went to location and switch the routers on the upper floor. I started the settings and changed to bridged mode.
Problem: Regardless what i do, i always get the message : cable unplugged. but the cable is not unplugged, its connected to LAN4 / wan slot...
I have tried other ports too, but the problem is the same. Diode blinks on each port i have tested... If i switch cables back to old router, everything works just fine.
Where could be a problem ?
This are few setup pictures:
