Randomly each week, sometimes twice, my X4300 node goes offline. When it happens and I look at the node, the light is red on it. This is one of the satellite nodes, which is the living room node. When it goes red, it takes at least 5 minutes before it comes back online and then it is fine for a while and then bam, offline again.

The system is fully updated and it is affecting only this single node. 

Any ideas?
