@Omargon10 I guess you're aware that any universal adapter able to provide 12V and at least 1A will do. There's even one in the AmazonBasics line (should you not trust unknown brands)

@mocelet thank you for your reply.

However I've seen another threads where root cause of the issue is because using non-original power adapater.

Have you faced it?

@Omargon10 Not with C6, but it wouldn't be my first device with a non-original power supply. If people have problems it's probably because they're using a bad / fake / low quality power supply not able to supply the required 12W the Archer needs.

It's just a power supply, as long as it provides the required 12V and 1A (with correct polarity) the device won't care. Stability issues arise only if it cannot supply the energy, just like in any other electronic device, for example a computer or graphics card.
