Hi guys yesterday my antminer s5 stopped hashing, I was using it at f2pool along with other 4 machines. I had seen that the rejected rate of all the other workers was 0.2%, while my faulty antminer has a rejected rate of 3.7%.

I had done the following:
1)changing the network cable (Cable is Working perfectly)
2)Changing the psu (PSU is Working perfectly)
3) Tried to reset the machine (i cant get it to reset)

I must said that when I power up the PSU the fan on the antminer goes live, making its hideous blowing noise like all the other 4 machines.

I Can't access the machine via its web interface. the router doesn't give it an IP.

I Tried connecting directly my laptop to the machine via ethernet with wifi off,  Assigning IP 192.168.1.1 mask 255.255.255.0 Default gateway "BLANK", primary and secondary dns "BLANK" to my laptop and putting 192.168.1.199 on my browser to access. IT DIDN'T WORK

I cant use the IPREPORTER.exe it says that it isn't a valid win32 Application.

Using the advanced ip scanner (freeware http[Suspicious link removed]) it can't find the machine range 192.168.0.1 - 192.168.2.254

I Find weird that the faulty antminer cant get an IP, cant hash, however its fans turn on and work like it has always done.

The only thing that i can think of will be to use another S5 and unplug their hashing cards and connect the hashing cards from my faulty antminer to see if it is my PCB that is broken.

Please help me, im Totaly open to suggestions. I cannot lose my antminer because it still needs like another 4 months to ROI itself. HELP GUYS pleaaaase pretty pretty please.
