OpenWrt router configured as wireless repeater: can't access to webif or SSH

Hi guys!

I'm using an old AGPF router (Telecom Italia). I'm using an old OpenWRT release (15.05 chaos calmer). I've configured it years ago as wireless repeater. It works fine as repeater, but I can't access to any router panel configuration (webif or SSH). I wouldn't reset it, cause I don't remember the configuration and I remember it was hard to configure, due to the swapped wifi card I had to do to make repeater functions work.

Is there any other way to access to the panel?


Maybe if you connected to the serial port.
