I wonder if you people can help me find the firmware for siemens gigaset 504 AGU Router. I want to install the firmware, because it is not getting configured. Every time I enter the advanced setup, it comes back to the main log-in page and nothing works.
I would be thankful, if anyone has exprience of it. I have done this with D-Link routers but can't seem to find the software for this one.
