In the early hours of this morning, there was a blip showing on the TBB monitor. I assumed it was just a resync or some maintenance work. I've since been unable to access the GUI of the Zyxel, so perhaps it randomly rebooted? DSLStats has also stopped recording. Everything else appears to be working fine though. I'm still getting the throughput that I was before. I'm fairly certain that I'd changed the IP address to access the GUI, to 192.168.1.254. But this doesn't appear to be working. Is there a way to find out what the IP address might be? I'll just restart it, if not.
