My R4 stopped working today. Currently if I power it on, I will see its Ethernet LED in solid yellow with blinking green. Miner does not appear on router table. Has anyone encountered similar experience with R4 or other Antminer models?

Thanks.

I had exactly the same problem and the IP report button reset method helped me to fix it.

See this older post by me:

Well, this is an interesting find and I thought I'll share it with you.

I had a problem booting my Antminer R4 8.0 Th/s, batch 2, autotune-model.

So I went looking in here:
Bitmain.com: Three Ways to Restore Factory Settings (R4/S9/T9)
https://enforum.bitmain.com/bbs/topics/3957

I used the last option in the list, IP Reporter button restore.

Usage: Please power off the miner, then hold down the IP Reporter and dont release it. At the same time, please power on the miner.
Releasing the IP Reporter after 5 seconds, the machine will automatically restore factory settings.

My miner restored with firmware Aug. 9 2016 and autotune settings were gone.
I am now suddenly able to control frequency and custom fan settings. Cheesy

This was not my original problem, but I'm happy with it.
My original problem was that the miner jammed somehow in the booting process and didn't even show up in my router ip list.
