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)

1. Which components commonly fail first after water damage on the Archer C6?
2. Is there a fuse, protection diode, or power MOSFET near the DC input that I should test?
3. What voltage rails should I measure after applying 12V power?
4. Are there any known schematics or boardviews available for this model?
5. 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!

I tried the power adapter on other routers that I have and it turns them on, so the issue is not in the power adapter.

Is there anyway to fix C7 which does not turn on? Thanks for your help in advance.

I’ve read the online articles. I need to hear from someone who has one already.

I have an Airport Extreme and a Time Machine server. I have a Spectrum internet that constantly acts up. I don't know why I can't use either of mine to replace Spectrum's but it's not working. So when I buy a new one I want to plan for the future even if I have no immediate need. For example, once the stimulus check reaches me a big chunk goes to the mac mini M1. It's WIFI6 so the new router needs accommodate it. I'm a network nutso too. I started with twisted pair and then grinos for packet on two meter. So I want to have as much or little control over settings ergo WRT or at least open source router control.

Now the question for you and Dan: what inexpensive WIFI6 (meaning mac mini compatible) and open source os would you recommend ?

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

I was gifted a unify dream machine 4 port cylinder router with some other unify gear, unfortunately I wasn't the original purchaser so I don't have any idea of how old it is. The gifter said everything worked great when it was packed up but unfortunately upon receiving the hardware everything but the router works well. I have tried to plug the machine in with multiple power cords and tried to hold the reset down while plugging it in. When it is plugged in the fan will do a ¼ turn and then stop. It's almost as though it has a bad capacitor but I'm not really even sure how to open the unit with out any damage and don't want to destroy the beautiful machine. ⁹

It's a TCL router

Model HH40L1

It does not connect to any device but turns on
