Unifi Dream Machine: Unit wont power on. Any ideas how to trouble shoot it and or fix it?

Sat, 31 Jan 2026 06:29:40 -0700

Tldr: machine wont power up no fans or lights.

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

ARRIS Surfboard SB6183: My arris router went out after a thunder storm that struck close to me

Sun, 18 Aug 2024 05:26:53 -0700

I have a similar router to this one but it’s small and black and has no buttons. Recently a thunderstorm hit close to us and my power went out and then back on. Now my router won’t even turn on after I change cords or unplug it. I’m a total noob so I’m asking for some help with this problem. Thanks

Unifi Dream Machine: UDM Pro boot loop

Tue, 28 May 2024 07:06:43 -0700

I have a UDM Pro that has been running pretty good for a couple of years when it decided it would try to restart its self. When it did that, it went into a boot loop where it wants to be restarted. I restarted it a few times and even unplugged it to no avail. I am at a witts end on this. Any suggestions on fixing or should I replace it?

Ubiquiti Airfiber 5XHD: Where can I find schematics or IC identification for board components?

Wed, 31 May 2023 09:47:07 -0700

Cannot find proper component needed. the chip im looking for has physical damage but i can still make out most of the numbers on it which are "54260 18F" the other numbers i believe might be "S101" but again the chip was physically damaged where the last numbers are. if anyone knows of this chip or where i can go to try and identify this component i would greatly appreciate it. the company that manufactures this device is refusing to release any schematics or diagrams with the information i need and i cannot find any information on the net

Unifi Dream Machine: Ubiquiti UniFi Switch US-8-150W missing 3.3V on mainboard

Wed, 04 Jan 2023 05:53:34 -0700

My Ubiquiti UniFi Switch US-8-150W (USW8P) suddenly stopped working and became 100% unresponsive. It's just a month out of warranty, but nothing to do from the official site.

Dreading the common PSU problem, I have verified that the PSU is outputting 53V DC and that I can easily draw current from it.

On the mainboard, I have verified that the 24V POE voltage is available on the far end of the board, for all 8 ethernet ports. But on J9, I notice the 3V3 isn't available, which I guess is the main problem. There is no apparent damage to be seen anywhere.

I've been searching the net for schematics and clues as to what might be wrong but found nothing.

Can anyone here help?

-------------------

Update:

Thank you Alisha C @flannelist for your nice answer, where you suggest I update the question with some pictures.

The USW8P board looks like this:

On the lower left 53V DC is coming from a tiny but capable 300W PSU.

Lower mid is a connector marked "3V3 R T G" which I presume is for debugging, but people also use it to run a small fan. 3V3 is supply output and G is ground. The function of R and T is unknown.

The 3V3 on this connector is missing.

On the right-hand side of the board are the 24V POE power circuit, where both 53V (input) and 24V (output) are present as expected.

I started tracing backward from the missing 3V3, identifying components on the way, and ended up with this:

The chip closest to the connector with missing 3V3 is an AZO1212, EZBuck 3A Simple Buck Regulator. Its input appears to be cascaded from another chip, the LM5071 Power Over Ethernet PD Controller with Auxiliary Power Interface, where the circuit follows the single Isolated Output application note to a reasonable degree, except for no actual POE supply, only an auxiliary supply):

The big EP13 transformer looks very much like the PA1367NL, and appears to be functioning.

Studying the PCB very closely I discovered a tiny amount of black residue on one side of C2571 and was able to determine that it was short-circuited (zero ohms, also after desoldering) - in the application note this corresponds to one of C7, C8, C9, or C10. With the shorted capacitor removed, the resistance across the remaining capacitors became 1 ohm, which also appears to be way too low for anything healthy.

With power connected to the board again, I measured absolutely no change anywhere.

I'm pretty sure the error exists somewhere in the circuit around the LM5071, but I have no idea how to locate it further. Switchers are pure magic for me.

Any ideas for how I can continue will be highly appreciated.

Also: Happy New Year everyone. :-D

OnHub: Red circular light and the loss of internet connection

Fri, 07 Oct 2022 15:00:06 -0700

The OnHub router worked perfectly for about 6 months and then suddenly light turned red which resulted in the loss of internet connection. A call to the support did not help. The router was bought during a visit to USA (from Copenhagen, Denmark).

OnHub: Looks like I fried my onhub router. Can you help?

Tue, 23 Feb 2021 01:33:21 -0700

So this evening, my favourite Onhub router of 2 years stopped working. Thinking it to be a problem of adapter , I looked for another adapter to try and in a haste I plugged in laptop’s adapter in the router . Heard the kink sound followed by burning smell , that was the moment I knew I have done a blunder.

(Later found that the MCB had dropped for those switches that’s why the onhub adapter didn’t work, laptop was kept in a different area , the switches for which weren’t connected to that particular MCB)

My question - Is it any way possible to get my onhub back to working again or should I just forget about it? Right now there is no light at all emanating from OnHub. (The original adapter is working fine as I have checked it by testing in other spare routers.)

OnHub: Why might my internet connection be slow?

Thu, 12 Nov 2020 04:56:45 -0700

I have a problem with my TP-Link TGR1900 (Google OnHub) router. My ISP gives me 250 Mbps. I have tested my service by linking ethernet directly to modem. It is good. At one point after I reset my router, my initial test was around 250 Mbps through the Google WiFi app. But when I tested again, it dropped to 30-40 Mbps. I have:

- reset router

- rest modem

- tried different ethernet cables

- disconnected my ethernet switch

Nothing seems to help. Do you have any good ideas or should I just buy a new router?

Ubee DVW23C: Is this at all compatible with DD-WRT?

Fri, 20 Mar 2020 16:52:53 -0700

The Broadcom chip inside is also inside other routers the are, but this is a modem/router/telephone combo. Even if modem and telephone functionality are gone, is it possible to use alternate firmware. The manual says it is compatible with TFTP firmware upgrades.

Novatel MiFi 2200: novatel Mifi 2200 power won't come on

Sun, 04 Nov 2018 13:34:12 -0700

Novatel Mifi 2200 when I try to power on, there is no light on the power switch. Could it be the battery is dead? I plugged it in, pushed the power button but no light. I took the battery out pushed the power button 5 seconds and put the battery back in and pushed the power button for 5 seconds, still no light. If the battery is dead how long will it take to see a green power light when I plug it in?
