No need to download software to find it, reset will put it back to stock.
Sorry but sounds like your ethernet control card is pooched.
Easy test if you have a spare miner or a spare control card.
Should be no problems to get in, if you can't login to the miner, the control card is faulty.
Resetting ECB's puts a lot of wear and tear on those cards, so if you done that a lot, that's likely your reason.
Those ECB's are cheap made to begin with... instead of buying a Raspberry Pi.
Yeah... unless it's a problem with your other hardware then, the ECB's the cuprit.
Also, remember to put your own PC on the 192.168.
1.xxx before logging in the miner.
You might get kicked off the internet but this is what allows you to login the miner.
Hope this helps.
