I have had the same issue with the 204 getting stuck on #3 4-5 times now. Both using a static IP / DNS(used google's dns 8.8.8.

and using DHCP. When the issue happens, sometimes I can ping the 204 but usualy not. I always have to power cycle it to fix it. And as the 204 is not nearby my usual location it is a pain to have to go to it.
Most recently the 204 was stuck on #1. It had a static IP / DNS and had been running for a couple days. For no apparent reason it went offline. After power cycle its fine.
It seems most people have had their 204 be very reliable yet I am having to power cycle it every few days. Any ideas why? I am fairly knowledgeable with networking but this is stumping me. If this issue is resolved I would potentially buy many more of the 204's as it is providing a great convience to me when it works.
I would appreciate any suggestions.
Thanks.
