This discussion in Español (Spanish) is for beginners who are not ready to waste money. Good replies should explain what to learn first about power, heat, wallets, profitability, firmware, and realistic expectations.
This kind of thread is useful because the same symptom can come from different causes. The best replies are the ones that show the exact setup, the tests performed, and what finally changed the result.
I had something similar happen and the fix was much simpler than I expected.
I like this topic because it gets closer to how mining actually works in the real world. A lot of people read generic advice and assume the answer is always hardware or always pool-side, but in practice it can be wallet format, DNS, latency, stale behavior, unstable power, or simple operator error. The more details people share, the more useful this thread becomes for future readers.
I had a similar situation on a smaller setup and the lesson for me was not to assume profitability or stability from one short test window. Watching behavior over a longer period gave me a more realistic picture.
This is exactly the kind of question many new miners search for before they commit money or hardware.
I think the most helpful answers here are the ones that explain what to check first, not just the final fix.
A practical comparison with real setup details would make this thread much more useful for future readers.
It helps a lot when people include what symptoms they saw, what they tested, and what actually changed the result.
This is a strong SEO-style topic because it matches the real questions miners keep asking again and again.
