The sticker does indeed say 192.168.1.99. I'm not able to browse to it. It won't show anything.

I bought a 650w psu for only 1 antminer, updated java, hard restarted the miner...still nothing.
My ipv4 settings are
Ip-address: 192.168.2.254 (different from miner)
Subnet: 255.255.255.0
Default gateway: 192.168.2.1

Also my 'obtain DNS server address automatically' button is greyed out, even though the guide says it needs to be checked.

Any ideas?

I'm using a 450w psu I used a few years back. Thought it would do the job. But if it's my psu, why did it load the interface the first time for me to change the wan settings? I didn't enter my mining credentials yet.

After 4 hours of searching for answers for why my antminer apparently doesn't exist, I've given up.

I received my antminer s1 earlier today, set up the psu, grabbed a 'how-to' guide and started following it. I've entered the IP address of the antminer in explorer (didn't work with Chrome), followed the guide to change the settings and suddenly every connection to the miner was lost. I've triple checked the numbers and everything was exactly as the guide said. After trying to establish a connection to it's IP again, I decided to do a factory reset, following another guide on this forum. I ran the advanced IP scanner tool to look for the IP address, but it still was nowhere to be found (yes, everything was connected).
Only when I enter the IP address, written on the white sticker on the antminer, I get a black screen with the words 'LuCI - Lua Configuration Interface'. After a few seconds this screen disappears and there's no connection anymore.
I'm out of ideas now and hopefully someone can help.

Cheers in advance!
