TP-Link Archer C7: TP-Link Archer C6 (V3.20) Water Damage - No Power After Getting Wet

Thu, 04 Jun 2026 21:06:07 -0700

***

Hi everyone,

My TP-Link Archer C6 (AC1200, V3.20) got wet after accidental water exposure. Since then, the router shows no signs of life when the power adapter is connected.

Opened the router and inspected the PCB.
No obvious burnt components.
No exploded capacitors.
No visible severe corrosion or damaged traces.
Antenna connections and main board appear physically intact.
Router currently does not power on at all (no LEDs).

Model: TP-Link Archer C6 V3.20
Power Input: 12V DC, 1A

(Attach all PCB photos, both sides, power section, and close-ups)

Questions:

Which components commonly fail first after water damage on the Archer C6?
Is there a fuse, protection diode, or power MOSFET near the DC input that I should test?
What voltage rails should I measure after applying 12V power?
Are there any known schematics or boardviews available for this model?
Based on the photos, does anyone notice signs of corrosion or damage that I may have missed?

I have a multimeter and am comfortable performing component-level diagnostics if someone can guide me through the measurements.

Thanks!

Cable Modem: Motorola MB8600 Only has a light on the bottom (Ethernet)

I have so far rebooted and reset in all ways that I could.

I am able to log into the admin console it gives me the following errors:

CMSTATUS:US_ Diplexer_Mode_Change:Fixed lnitial, 5-42MHz.

SYNC-Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing(MAC Address Here):M-OOS=1.1:CM-VER=3.1

Trying to see if this is in fact something that I can fix or if it's not worth my time -- either way I appreciate anyone's input

Fritz!Box: My Fritz Box 7580 is rebooting

Wed, 30 Oct 2024 01:08:06 -0700

Hello, I have an AVM Fritzbox 7580 that is stuck in a boot loop, constantly rebooting at random intervals. When WiFi is enabled, it reboots every 2–5 minutes, and even with WiFi disabled, it still reboots frequently. A visual inspection didn’t reveal any issues. Does anyone have any ideas on how to fix this?

AirPort Extreme A1521: New fan, high pitch noise

Mon, 23 Sep 2024 18:12:13 -0700

I just replaced the fan in my Airport Extreme today. Once i booted up the router, I'm now getting a high pitched noise. When I start the router, it initially doesn't make any noise. I can see the orange light, etc... But, once it starts "initializing", maybe 5 seconds after start, I get a constant high pitched noise. Since it's a brand new fan, I'm wondering if this is coil whine? If so, I don't understand how a new fan could cause this? Anyone have any ideas as to what's up? Or, maybe the new fan is just noisy? It's a sunon fan that i bought off ebay. Curious if anyone has any thoughts based on these symtpoms?

Doing some more research, I'm reading that sometimes replacement fans do have a high pitched noise. So, it might indeed be the new fan. It looks to be the same brand (Sunon) as the original, so I don't know why there would be noise. Very sad... Past my return period on this fan, too.
