[SOLVED] Packet Loss [PC]

[manfredisaber]

Hi,
I desperately need you help. On beginning of october I bought my first pc and got an ethernet cable running directly into it for best performance, but on 22nd of november I started experiencing packet loss in every server I want to get access to (telling this so you can shrink the circle of what causes it). I've been trying like everything I found digging about it, ma never got a solution. Here's what I tried:
-ping my router for 30 minutes to see if I got any packet loss, none
-QoS my bandwith to the very minimun (so I got 0 bufferbloat), none
-portforwarding, DMZ (on and off), several DNS (open's, google's, cloud's),UPnP (on and off), static IP, disconnecting off every other devices in the house, none
-I've got an ASUS AC52U (who worked very good until the first *unexplicable* packet loss), which I can definitely remove from the list of the causes, because I tried another router and showed up the same results, none

Here's other info from Pingplotter, (tried both google and some games servers) lets pick google results in this example:
1st hop, perfect (its the router)
2nd hop, 100% packet loss (it does not even show the IP, its all blank)
3rd, perfect
4-5-6th, variable packet loss
7th, perfect
8th, 6-10% loss
9-10th, perfect
11 (google) sometimes perfect, other times 5-10% packet loss.

In fact, packet loss shows up lets say 4/10 times while gaming, sometimes happens sometimes not.
I repeat that for 1 and a half month I've NEVER experienced packet loss. I can assure that is a ISP issue, but they keep saying "all is good by our end".
EDIT: my ping is always the same and never got problem about it. I've also updated everything a I got, drivers, pc and router BIOS

Got any help?

The test is not valid unless you ping all the nodes in the path at the same time when you are getting random loss.

A actual loss will show loss in every node say starting at hop 4 and every node past it at the same time. If the outages are very short even that maybe suspect.

The key is if say hop 4 was causing the problem you can never get perfect results in hop 9 because the data must pass through hop 4 to get to hop 9. If the results do show that then the loss in hop 4 is not valid.

Still this may not really matter if you consistently get no loss to hop3. This would mean your router and the connection to your house is fine. Whatever hop 2 to hop 3 represent is also fine.

The problem you have is your first level techs only look at the connection to peoples houses. Most have no knowledge about the rest of the ISP network. They also likely have no access to troubleshoot it.

Hard to say you need to show clear evidence that the problem start in a particular node but is fine before. You also need to show that it is not a abnormality in the test by showing it actually affect data to the end node at the same time.

Try sending it to the ISP via Email and ask them to forward it to a senior tech.....maybe you get lucky.

Now the problem maybe they have a overloaded segment in their network. They likely already know about this if they are even half competent. It is all going to depend how much it will cost the ISP to fix this. If it is a busted router they will swap it out. If they have to run a second fiber or something else expensive they likely will try to hide the fact that they do not want to fix it because it cost them too much.
