Duplicate IP error
So...I have relatively plain vanilla home network. I have a temp sensor that is too far from the router to keep a reliable connection. I purchased a RE105 repeater a couple of years ago. I set it up as a repeater using the default settings. It worked without a problem up until a few days ago. On 3/18, I received an email from the monitoring service that the sensor was offline.
As a first step, I power cycled the repeater, but it didn't restore the connector. I could connect my laptop to the repeater, but it didn't see the internet and the 'signal' LED wasn't lit. I then performed a hard reset. I set the repeater up using the same parameters as originally done.
Since I did that, when I connect my laptop to my router, I get a duplicate IP error and cannot connect to the internet. I can connected to the '_EXT' network on the repeater without a problem, but when I connect to the router, I get no internet. In addition, the entire network is unstable. Just for fun, I updated to the latest firmware, but nothing changed.
Is this a hardware failure? Is there anything I can do to verify or fix this?
