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?
