Sneaky Monkeys Forum _ PC, Website, Server & Game Support _ Packet loss

Posted by: Sir Robin (not so brave) Mar 9 2016, 01:46 PM

Hi, I got notified today by one of the server admins, that I have a constant packet loss of about 30% for the 64 slot limited archer server. I tried to see the problem from my end but couldn't reproduce it.

Here is what I got:

CODE

$ mtr -c 100 -r -n 31.186.251.152

I also tried to google for packet loss problems, but basically all I found was not to use wifi, but it's not an option for me.

Any advise?

Try pingtest.net to see if it shows packet loss.

Edit: BTW I was that admin, Sir Robin have 28~31 packet loss constantly
Some players have reported that closing AV web protection fixed it for them

Monkey offered me a lot of advice on that matter, haven't really got much time to look into the matter thouroughly, but got it all noted so will do one day.

Anyway if there's anything I've noticed is that you need to make sure that you turn off wi-fi on every other device (like cell phones for example) - usually my cell grants me another 6 PckLoss/minute.

Sorry I can't help you much here. From what Monkey told me I can only say that it's very likely to be your ISP's fault and it might be hard to get them to do anything, as always.

Edit: it is also possible that your connection to the router is faulty. Can't really elaborate on that in other ways than making assumptions.

Edit: it is also possible that your connection to the router is faulty. Can't really elaborate on that in other ways than making assumptions.

1. Make a .bat file and put this inside.

CODE

@echo off

set/p host=host Address:
set logfile=Log_%host%.log

echo Target Host = %host% >%logfile%
for /f "tokens=*" %%A in ('ping %host% -n 1 ') do (echo %%A>>%logfile% && GOTO Ping)
:Ping
for /f "tokens=* skip=2" %%A in ('ping %host% -n 1 ') do (
    echo %date% %time:~0,2%:%time:~3,2%:%time:~6,2% %%A>>%logfile%
    echo %date% %time:~0,2%:%time:~3,2%:%time:~6,2% %%A
    REM    sleep 1 >NUL
    GOTO Ping)

2. run it, enter your gateway (will be your router aswel) IP. should be 192.168.0.1 or 192.168.1.1 or 10.0.0.1 or 10.0.1.1 or 192.168.178.1 depending on brand/model. Let it run for say ten minutes.
3. hit Ctrl+C then Y
4. open the freshly created log file on your desktop and check if some packets didn't make it

You could also run it whole night long but I would recommend adding a line "timeout 1" just above the last line. So it doesn't alter your CPU and network performance.

Thank you all for the advice. I think the problem is, that I'm on linux and chiv client is probably a bit less developed for it. So what happens is, that initially I do see a big packet loss (and I have to wait a bit before I can join the game). But after that it's working fine.

But the value that's shown in the player list isn't updated very often. It stays the same for at least 10 minutes or more, so what you see is the value from my initial packet loss. On longer maps, like Belmez, I started with packet loss of around 70. I checked it during the game (when I got killed mostly), and it was the exact same number, which can't be true, right? I mean it stayed something like 70.5242 for more than 10 minutes. And near the end it suddenly fell to around 3. I think it's just a buggy stat for the linux client.

I'll try two more things tonight:
1. I'll connect with wired net and see how it goes
2. I'll try both wired and wifi on windows and check that as well

Tell us your results

I couldn't find long enough cable to try chiv without wireless, but I managed to try Chiv on Windows. The lost packets info is updated more often than with Linux, something like once per 2 - 3 minutes. The initial packet loss seems lower as well, though that's hard to compare.

The gameplay experience was quite similar. Windows has a bit better FPS and it fluctuates less that on Linux, but overall it was very comparable. So I think it's just the info that is not updated.

I forgot to ask earlier, but what's the effect of my packet losses (when they are there) to the server and to the other players?

Mostly warping and weird animations.
