Need help identifying packet loss and what to do about it.

Now i'm getting 5-10 sec lags, 3 min desyncs then DCs. - https://pastebin.com/furuhfxN

There is a problem within your home network. There's an average ping of 14 ms to your router, which is fine is that's a stable ping and not fine if it isn't. With a best ping of 1 ms and a worst ping of 3,611 ms to your own router, it is apparently not stable.

The worst ping to most hops on the log is in the region of 200-something.

Worst ping of 4,369 ms to your own router.

Most worst pings to other hops are in the region of ~ 300 ms.

Worst ping of 3,007 ms to your router.

Most other worst pings are in the 200s.

Much more stable.

Worst ping of 10 ms to your router, only a single worst ping over 100 ms - although admittedly it is significantly higher than that. But the difference is still night and day.

Packet loss beginning between your computer and your router.

Worst ping of 2,805 ms to your router. Most other worst pings are over 4,800 ms.

Then I apologise. Because I saw this thread last night and didn't post in it. It's not that I didn't bother - I did write up a response - I just never clicked the Submit button.

The reason is you saying this;

How can you help someone if they ask you to add 2 plus 3 and say they will not accept that the answer is 5? Your wireless connection isn't stable and there's no signs of a problem when you use an Ethernet connection. You insist on not using Ethernet regardless.

I'm happy to give people the advice that they need, but when they make it clear that they outright refuse to listen to it, I don't see the point. Nor do I understand why they bother to ask.

Wireless connections are fantastic - I love being able to watch Netflix on my iPad and go into the kitchen to grab a drink without having to pause the movie. But different technologies have different strengths and weaknesses. Nothing shields wireless traffic from interference, so it's subject to packet loss and unstable latency. Troubleshooting this is close to impossible, and even if you fixed it there's no guarantee nothing else will cause interference in future.

When people suggest wired connections it's not because we work in your local computer store and earn commission selling Ethernet cables. It's not because we're trying to keep WiFi all to ourselves. It is because it is - objectively - the best connection type for gaming.

To even attempt to find the cause of the interference affecting your network we would need to be physically present to look for potential issues. It just can't be done over a forum.

If there was a solution I would give it to you - gladly. But I can't look around the room for nearby electronics which could be to blame. I can't walk around your home unplugging appliances one at a time and then running more tests. I don't know what you expect of us.

If the router and computer are in the same room, use an Ethernet cable. Otherwise try a powerline adapter kit. Any kind of wired connection is more reliable than wireless ones.

If wireless connections were stable, nobody would bother with wires anymore. They're in the way and they get tangled and pets attack them and they collect dust. They're extremely inconvenient. So why do we put up with them? Try playing without one. That's why.

First of all, thanks a lot for taking your time, i know that last sentence is what it is, but wired would require me to drill through walls, which i'm not allowed so i have to stay on wifi if i want to play in my room. Can i ask about 125.197.broadband16.iol.cz showing 80% packet loss? I have a VDSL internet provided by ISP with a modem, so is that on my end or theirs? :) Or if there is any way to reduce this packet loss. In those other tests it's between 10-30% so what is wrong now? I also understand the ping ms, but mine spiked only 2 times in the 4800ms test, whereas i was getting lags/desyncs every minute

Powerline adapter kit. :)

You plug one in near the router and the other in near your computer. You use Ethernet cables - typically supplied in the box - to connect your router and computer to the one nearest them. They then pass your internet traffic over the electrical cabling in your home.

Sure. It is a lie.

It's important to understand what each line represents. The first is your router, the second is your modem, then things progress to your ISP, then they passes through backbone infrastructure, then they reach SoftLayer (GGG's host) and pass through their network to the server.

The final line is the server and what we are interested in. If there's a problem there, you work backwards to try to determine where that problem first appears. On the final hop we see 6% packet loss which is very close to the 4% packet loss reported at your router. We also see a massive worst ping, and again the first time we see that is on the first line of the log.

WinMTR claims the third line shows 100% packet loss. If that was true - if all of your packets really were dropped there - then we wouldn't get anything back from hops beyond that point. Traffic to each hop first passes through each of the earlier hops to get there.

The fourth hop, which you're asking about, shows a significant amount of packet loss. This means that the router, for one reason or another, did not respond to most of the pings sent to it. However, because the hops after it don't show similar packet loss, we can determine that hop 4 is forwarding your traffic normally. Thus the high amount of ignored pings is likely explained by either traffic management or just the router being too busy to process the pings. Routers use different hardware for processing traffic sent to them than they do for just passing things on to their destination, and the hardware used to process traffic sent to them can be needed for other work.

The router isn't a server and doesn't host the game; even if it didn't respond to a single ping - like the third hop doesn't - so long as later hops don't show a problem we've no cause for concern. Its job is to forward your traffic, and it is doing its job just fine.

first line comtrend.home is my modem, which goes directly in the wall but still the packet loss is amazing
125.197.broadband16.iol.cz - 87 | 23 | 3 | 0 | 13 | 14 | 14 ¨
edit: says 97% now, still running, so what it's blatantly lying to me?

Let me ask you something.

Hop 2 shows 100% packet loss.

Hop 3 shows 87% packet loss.

You care about one but not the other. Why?

Because Hop 2 says No response from host, whereas hop 3 gives me an indication on where packet loss occurs, okay so i wont focus on those, gotcha. :)

No response from host just means that WinMTR didn't receive a single response from that router. We don't have a hostname for it, sure - but from its position we can figure out roughly where it is on the route. It's after your modem so we know it's not your home network. It's very soon after your home network so it is, almost certainly, belonging to your internet service provider.

But it's honestly not a problem. I'm far more concerned by the extreme latency spikes I see on the log. Your ISP's router is either busy or just configured to not like ICMPs very much.

I was so busy focusin on the !!!!packet loss!!!! thing i wasn't even reading how much data is sent there, it just means the isp uses 2 separate ips to go through and right now one is working and the other one is not used - that's how i understand it, i skipped the wifi and no i'm on ethernet in next to the router, and the connection is very stable -https://pastebin.com/DU8qQNVj

Not willing to consider a powerline adapter kit, then?

I googled it and the first result costs €19.49. Now, granted this may not be the best, most amazing kit ever - but I do think they're generally an affordable option. I understand that after just spending money on networking equipment you probably don't want to spend even more on it, but if you'd asked before then we could've suggested this instead. :/
