hello,

i used mtr to test packets loss and with udp i gets high packets loss but with tcp and icmp no packets loss can this affect gaming and streaming as they both dpends on udp here is my result ping using udp to 8.8.8.8

    My traceroute  [v0.93]

You can only control traffic up to the ISP equipment at most.
There's a small chance to solve the problem on the ISP network if any.
Anything beyond the ISP infrastructure is typically impossible to change.

However, if you can see the problem, the ISP can also detect it.
If they have not solved it yet, the reason is likely one of those:

  • Solution is economically unjustified
  • Lack of technical capabilities
  • Out of control area

Also note that packet loss can be the result of:

  • Hardware and software resources limitation
  • Traffic shaping, analyzing, censorship

Moreover, UDP traffic can be processed separately from TCP.
So, the losses for UDP and TCP can vary significantly.

In short, that's normal and you usually cannot change it.
Although some cases can be work around with a VPN.

@Vigo,

The ISP can also be:

  • intentionally dropping traffic destined to their equipment
  • dropping traffic across their core equipment with TTLs that will not forward thru
