Network packet loss issues (RESOLVED, PLEASE CLOSE)

[anrkyuk]

Greetings one and all.

So, yesterday I was playing Minecraft with my nephew on my Realm and I was suffering from intermittent lagging, about every 8-10 seconds lasting for a second or two each time.

If i was mining there would be no block breaking animation, just all of a sudden the block would pop, and if there were items on the floor I'd just walk over them and not pick them up.

I at first thought this was a Realm issue, but my nephew was not having any problems so quickly ruled this out.

After playing I went to do some shopping online and noticed google was slow providing search results, and so was Bing... and shops were also slow to provide results from searches.

A quick Google ping test showed that I was suffering frequent timeouts.

This was on my desktop gaming PC with a Netgear R7800 router and Virgin Media Hub in modem only mode.

I started by rebooting my PC = no change.

So I turned my router and modem off for 5 mins and powered back on = no change.

I tried a different cable on a different port on my router = no change

I flushed my DNS = no change

I changed my DNS to Google = no change

I ran Spybot and Malware bytes with nothing nefarious showing.

I then tested my Surface Pro 6 over wifi and it was suffering the same issues in Minecraft and Google ping was also suffering frequent timeouts.

I then updated my router firmware = no change.

I went on to VM's website (My ISP), a location check showed no known issues, I then used their web based tools to check my HUB (modem). It showed no issues and advised that I power cycle my modem, which I had already done.

Sadly I know only 1 other person in my street with VM and a computer an they are out, otherwise I'd ask them to run some checks to see if its the ISP at fault.

The only thing left I can think to try is to connect an old PC directly to my modem and or to put my VM Hub in to router mode to bypass my router.

Any thoughts ?

check the router settings, disable any kind of packet acceleration

[anrkyuk]

Greetings _I_

I couldn't see anything labelled packet acceleration, a quick look on the Netgear forums indicate that disabling QoS > WMM (WMM: Wi-Fi Multimedia) solved someone packet loss issues on the R7800, this sadly has not helped me.

Another post had multiple people advising an older version of firmware solved theirs, again, no joy.

Other than a potential hardware level or ISP issue I'm struggling to think of the cause as one day it was fine the next it wasn't, I had not installed anything and to my knowledge nothing updated.

Scratch that... this doesn't look good...

Try turning off the Hub’s firewall. I was seeing 100% packet loss & this solved the problem.

[Elucidator]

Do you have any service to the internet opened up on your network? It seems odd people are trying to scan your modem.
Those 'attacks' at least indicate the firewall succesfully blocked them.

---
I checked the IPs, I don't think they are attacks.
Have you recently looked up a lot of Virtual Private Server hosting websites or platforms? Because all of those IPs by coincidence are from such stuff.
From VDS, to Ovh, to insert some datacenter hosting provider name I gues..

Anyway, it seems that these 'servers' for some reason attempted to communicate with your network for some reason, and then the router blocked it.

---
Slow internet:

Try testing your internet speed, jitter, and look at websites that indicate outages or downtime. Maybe your ISP is having problems.

What you described is pure network related lag though. It has to do with connection.

After the problems started, when I assumed it was Minecraft Realms playing up I made some searches on google and reading on Reddit about minecraft server hosting but the only sites that I looked at were Apex and Hostinger.

As stated, this was after, about 2 or 3 hours after the issue was first noted.

Prior to that the last time I looked up VPN/Hosting related stuff was over 2 years ago.

Just to note I've used my phone to get my Surface Pro on the web and there was no issue, so whatever this is it's either my R7800 router, ISP modem, ISP or something external.

[Elucidator]

Then it is a bunch of bots running on those hosting providers their service trying to see if you host a website or for some reason port scanning for no reason, other than data gathering (by hacking) but the log is there so the attempt failed.

It maybe advisable to update the firmware of your router and then reset the device anyway at least.

You're not under a attack at least. The timestamps are too far apart and those packets are extremely small. If you're under attack, you expect to see 100s of pings like that under the same second.
so idk what this is exactly, but its ... ignorable for now. Assume its a selfish jerk trying to look for ways to ways to cheat in life by abusing holes in a network.
It is at least an idea to report this to the internet service provider, though I assume they also have a log of these connections.

Ok, so running tracert on google provides the following info...

1 <1 ms <1 ms <1 ms (MY IP redacted)
2 * * * Request timed out.
3 8 ms 10 ms 13 ms lutn-core-2a-xe-233-0.network.virginmedia.net [62.252.71.65]
4 * * * Request timed out.
5 10 ms 11 ms 10 ms eislou2-ic-4-ae0-0.network.virginmedia.net [62.254.59.130]
6 16 ms 12 ms 13 ms 142.250.160.116
7 13 ms 13 ms 13 ms 216.239.41.193

9 12 ms 11 ms 11 ms lhr25s32-in-f3.1e100.net [142.250.180.3]

Virgin media is my ISP, would my assumption that the timeouts both occur when routing through my ISP's servers indicate a problem their end ?

[_I_]

its normal for isps to block their first few hops

ping -t those addresses, until you get spikes/loss
then hit ctrl-c to stop and show min/max/avg and loss

[A&A]

Check with pingplotter where is the problem
It will show you where are the packet losses

is it connected over wifi or by cable ?

[Elucidator]

I would recommend trying to ping mojang instead, since your connection with the server is in their realms.
idk where they keep their realms though.

I should note that a Minecraft Realm is by default seemingly slightly laggy, but only slightly.
And with most things you don't notice this. (you do with combat for example, you need to hit attack earlier otherwise they hit you)
And blocks instead drop their item with a slight delay.

(expensive and laggy xd) but uh yeah-

I am guessing it may have been temporary. Perhaps the ISP suffered issues. (idk if your nephew lives in the same house as you or not, but if they don't, its possible your isp temporary suffered issues)
Maybe today it works better, idk.

If i was mining there would be no block breaking animation, just all of a sudden the block would pop, and if there were items on the floor I'd just walk over them and not pick them up.

This can also happen when the server is slowed down (because its busy with windows update or some other nonsense)
You expect this to be temporary as well...

So far I don't see anything odd (with the results you have from today at least).

By the way, if you're okay with sending your personal data to the NSA (which owns oracle)
https://blogs.oracle.com/developers/post/how-to-set-up-and-run-a-really-powerful-free-minecraft-server-in-the-cloud
Then this is an option. Would diffidently provide enough power to run any modpack as well, and it won't cost you anything, other than your data e.e;

(people don't like oracle for other reasons as well, but this is quite nice 'd say)

I was going into the NSA so often and I was looking so good they introduced me to "Snowden"
and said I would be in the movie

There may be some port scanners, but that is pretty normal - check your own logs and you will probably find a ton of port scans and hacking attempts too
