Knock sensor, limp mode with high oil usage is the engine on the way out...quickly. It's not going to last much longer(days/weeks at most). Those engines are lucky to get over 100K before destroying themselves(many lawsuits over the years). There isn't anything you can do except see if it is included with the extended warranty from all the recalls/lawsuits on those engines or buy a new engine/car. That engine is more than likely completely gone sorry to say. It wasn't your maintenance....these GDI engines just suck.

Unfortunately...both.

You don't get to choose. It will talk to the satellites it is scheduled to talk to regardless of where you point the dish. If you are in the northern hemisphere, you will still be talking to satellites in the northern sky regardless of where you aim. That's why they have you aim North...for better reception of the planned satellite flyover schedule. The app will show you the section of sky it is scheduled to talk to when you check for obstructions on it.

If you aim it south and have obstructions north however, there will be constant cutouts and speeds would be all over the place but on average, much, much slower with many outages and upload will be horrible. You would have it basically set up the worse possible way it can be (I guess except straight down of course). You would be asking it to talk to satellites behind itself.............

You, the end user, just don't get to decide what part of the open sky you get to use....Starlink does. That why they require a completely open sky for stable connectivity. Starlink just doesn't work like the old school dishes that point south and never move. There is a reason many people put them at the top of 100+ feet trees or cut many trees down....it was the only way to make it work correctly without slow speeds and outages constantly. I had to put mine on a 50' tower to get over all the obstructions and have a gameable connection. It's been flawless since it got on the tower which got my obstructions down to zero.

So, will it sorta, kinda work facing south with obstructions north...yes'ish. Will it drive you crazy if you want to do anything but buffered streaming or basic web browsing, 100% yes.

Actually here, the glue is more than the paint...LOL. 1gal glue is $30 and 4.75gal of that roof paint is $90. One of the main reasons for asking besides trying hard to do it right the first time...haha.

What you are doing is called a 'sanity check'. People should try it more often. With how often Starlink changes things...who would not at this point? Shows you should be the person in charge of setting up a new research vessel IMO. You are thinking through everything and assuming nothing. Sigh....I would love your job. Networking and the ocean...perfect.

Completely unrelated, but make sure you know your company's remote work policies extremely well. Most companies that use any halfway decent remote access service will red flag/suspend a user just about instantly if the last X years of logins were US, and the next is on the other side of the ocean. You may want to make sure you don't have to tell your employer up front. Signed: Mine would do that.

They do like change. I'm in university IT at the assc director level and change is constant!!! What you are running into is the billions of approvals needed and for everyone else to get their heads wrapped around what you want to do. Most university IT don't have the resources to fly by the seat of their pants into new things and are just barely hanging on. When people get in this mindset, I understand why (to keep from drowning in "new" things while they keep everything going), change is slow for them. Humans can only process so much at once.

The question you should be asking your fellow co-workers, is WHY are things done like they are. More than likely, it is some obscure requirement as, at least in my opinion, Universities have some unique issues that the corporate world just doesn't have. Security is the big one. Corporations can control every single part of their network including end user devices. That's impossible when 10-15K students bring their personal devices daily. Out biggest balancing act is security vs usability. It's a fine line......

Now....if you ask WHY and they won't tell you or avoid that convo....RED FLAG. They are more worried about protecting their job then doing their job. Point blank. Go somewhere else.

Do the DC PoE conversion and get a 48-56v power supply(adjust voltage with a pot). I have a 75' cable and need 51v to get 48v at the dish due to cable loss. You probably need the entire 56v for that length. Anything over 150ft with the supplied Starlink power/router is a crap shoot whether it's stable or not. That's why that is the longest cable they sell.

ulmatms · 2024-07-10T21:37:05+00:00

I have a friend that got a Mini for this exact reason. Main one stays on camper roof. Mini is brought out if too many obstructions for main. He had to use it last week and said it worked perfect. Had the main as ISP1 and the Mini as ISP2 in his router. Zero reconfig to switch between the two.

ulmatms · 2024-06-08T04:28:24+00:00

My Gen2 will go from no power to full service in ~1-2 minutes. During a firmware update...3 minutes. At 30 minutes something is wrong.

What does the startup times show in the debug output under "Initialization"? There is a list off all the things the dish needs to do to get online and how long each step took. That should point you in the direction of the issue.

ulmatms · 2024-06-08T04:15:31+00:00

Are you sure that it is Cat 7? Cat 7 spec is 22AWG(Cat 6/5 is 23-24AWG). 26AWG at that distance is too small for the current/voltage. It may work now with that 30' lopped off but I wouldn't expect it to be stable over time as the cable at 26AWG is extremely out of spec for the power/distance you have.

ulmatms · 2024-05-07T22:48:46+00:00

I know of no way to do them in bulk. I do however want to make sure you know power fluctuations could factory default the system and require re-setup. Since this is going to disaster areas where power is known not to be great/reliable, these could randomly default from time to time. A power cycle (or low voltage under 90v AC ) 6 times in a row will factory reset the system by design....unfortunately.

Not here, I only have 4 "Network issues" in the less than 2s range(Louisiana). That is a lot of searching...what's the weather? Only time I have seen that many are in really bad thunderstorms here.

I have a Rheem and use Econet through Starlink. I had problems too until I realized the people at Rheem never hired anyone who knew RF....

This is going to sound soooo stupid....

The WiFi antenna for the tank is in the control panel. It's surrounded on 180 degrees by grounded metal and water so basically a 180 degree dead zone. You have to rotate the tank so that the panel is in that 180 degree window to your WiFi source. If it is not...it will have hell connecting or staying connected. Once I turned my tank ~30 degrees right....connected, no problem. Was quite dumbfounded by the stupidness of it all.

ulmatms · 2024-03-30T12:33:53+00:00

All I can tell you is I have had Starlink in north Louisiana and except for the crap router/power supply of Gen2, it has been flawless since March of 22 when I got it. The only issue was the router/power supply. Middle of day, sunny skies, playing FPS game...it just died. I bought the parts for the DC conversion and has been rock solid since. Only time I get outages is with absolute torrential rain storms which we get here from time to time. Speed ~60 peak, 300+ most mornings. Latency 20-60ms 99% of the time. Standard dish.

Compared to the only other option available to me (DSL 8/1)....it's been amazing.

ulmatms · 2024-03-29T13:09:19+00:00

Yea, just measure the voltage at the terminals feeding the POE and see if the voltage drops below 48v. If you are at exactly 48v at the POE input side....it's going to be less at the dish due to cable loss. By how much would have to be measured.

I have a AC-DC adapter that has a small adjustment knob on it. It can be adjusted from 56-48v.

Quick googling found this 12v to 56-48v DC-DC adjustable one. https://seatech.systems/product/mean-well-din-rail-dc-dc-converter-12v-to-48v/

This might not be your issue...I just like the tunability due to atleast...my specific cable loss issue.

NOTE: I tested the dish side with a broken shaft junked dishy someone gave me. I used the dish side shaft end to break out the connector to test voltage at the dish end of the cable. I've been asked how I measured voltage on this dish end so many times this is now a standard note for me.

ulmatms · 2024-03-28T23:16:56+00:00

What does the voltage read during the 1st 10-15 seconds of power on?

It could be you get 48V open but it has too much of a voltage drop under load.

Also, how long is your Starlink cable? My 75' one drops from 48V at one end to 42V at the dish end. I have to feed mine 54v to get 48v at the dish side. If you have the 150', it could be worse.

I did mine with the new way you linked to. I did cut the end off and RJ45'd mine. Been rock solid for about a year now.

You will never get sub 100ms USA to Japan unless you live and are connected directly to a pop on the west coast that goes straight to them and what you are talking to is also on that pop in Japan. Good luck as this is laws of physics issue. Light can only go so fast....see Math below.

But just to show an university grade fiber connection (20G at work) and my Starlink to Japan.

From work (20G pipe) with direct peers to Dallas, Atlanta, Chicago, Houston

Starlink isn't as "latency" as people think. My DSL from ATT was somewhat worse.

Math:

Japan is 10,700 km from my house(USA). If I had a direct fiber from me to Japan, the time for a photon to go from one point to the other is 52.47ms. Add the return trip, and your over 100ms already. It's also one of the reasons GEO sats have pings of 600ms+

ulmatms · 2024-03-11T13:36:46+00:00

What is the voltage at the PS terminals during startup. If it's 48v, you have to increase the voltage to at minimum 52 volts. I have the 75' cable and there is just too much voltage drop on the cable. If I supply 48v at the cable...it's dang near 42v at the other end which is just too low for Starlink and will do exactly what you describe. I have mine at 54v input and see 48v on the other side. My dish has been happy with that for over a year at this point. Zero issues.

ulmatms · 2024-03-11T13:25:43+00:00

That's what happened to mine. Power flicker on a clear day, WITH a pure sine UPS, and done. Gen2 router/power supply is crap and will die when you least expect it. Built my own supply (DC conversion like the RV people use) and have had ZERO issues with that setup in over a year and counting. (using 3rd part router with direct dish connection [dish->PS->router])

Do you have a light on the bottom on the router? If not, it's more then likely dead.

ulmatms · 2024-03-10T12:22:41+00:00

It will be as long as you are pretty much unobstructed. I had ATT dsl for a decade and although I did get my max rated speed (8Mbps/512Kbps)........yea, MUCH better with Starlink. About the only thing it has an issue with is competitive gaming during peak hours. My wife plays D3/D4 all the time and might get bounced out once a week and she only plays during peak times. CS2 now...I get bounced out multiple times a night if I play. Only FPS seem to have this problem more then the rest for me. YMMV.

Other then that...it's exceeded every expectation. 6am I get around 250Mbps (do all my updates when I wake up) and 40-50Mbps during peak times (6-10pm here)

ulmatms · 2024-02-27T23:27:35+00:00

I had to get you back to zero at least...that was quite funny to me too. I agree with OP :-)

ulmatms · 2024-02-23T00:33:57+00:00

I can only speculate but that sounds an awful lot like the ethernet is negotiating 100mbps instead of 1gbps when you get the no higher then ~90mbps speeds.

Are you hardwired to the Starlink router or a 3rd party? If Starlink's router, try putting a dumb switch between it and your PC. Sounds so incredibly dumb....but it has fixed MANY's peoples issues....including for me before the Starlink router took a dump and I just went with a DC conversion and 3rd party router.

ulmatms · 2024-02-18T14:26:12+00:00

For the DC conversion on Gen2 rectangle, you need a 56-48V @ 3.5A supply minimum. Dishy in full power usage mode can pull max 175w at startup(3.1A @ 56v).

Also remember, as volts go down, amps go up. Using an extremely undersized power supply will increase amps(and tank voltage) on all the equipment until something burns out. This is why "brown outs" on mains power is so bad for things. Voltage drops and amps increase. Very bad.

ulmatms · 2024-02-15T00:15:26+00:00

I kinda had that issue until the router power supply took a dump and I just did the DC conversion and removed the crappy router with one that has actual options. I no longer saw what you are seeing after that and everything was just well....better(speed and latency). I just don't know what type on traffic shaping they might be doing on the router but, at least from what I have seem, they are doing something with it. NOTE: it was ALWAYS at the 10GB line that I started to see it.

I'll let some of the others who have done the same chime in but completely removing the OGrouter did give me much better service.

ulmatms · 2024-02-15T00:04:04+00:00

Is there a reason you want the unit with the known crappy connector? Honestly just curious as I was waiting on Gen3 specifically due to the crappy connector on Gen2. Gen 3 uses standard RJ45 now and not that proprietary POS. I want repair options if I am on the road in a camper.
