Packet loss and high Latency, almost unplayable

Hi, gaming for me the past month has been a very frustrating experience mainly due to packet loss making any competitive game borderline unplayable.

I'll supply a few trace routes some EU game servers and googles dns.




























Tried a lot of troubleshooting already such as changing Ethernet cables and factory resetting but nothing.

Re: Packet loss and high Latency, almost unplayable

Hi FrancisM123,

Thank you for doing some trouble-shooting prior to posting, much appreciated Smiley Happy

My tests from here are not revealing any issue that might result in packet loss - there is no substantial Internet usage in your area and there are no service-affecting faults on the upstream segment.
Hub power levels and modem SNR are within spec too so no obvious Hub-related issues. 

My ping test from the default gateway (at the CMTS) shows no packet loss either:
Sending IP ping to: from **.**.***.*
ping ( 100 data bytes

1000 packets transmitted, 1000 packets received
 round-trip min/avg/max = 9/10/30 ms

Some important questions to ask at this point are:

  • Do you experience any broadband performance issues with other Internet activities (besides gaming)?
  • Do you normally connect via Ethernet or Wifi (I suspect the former given that you've changed cables but would like to confirm)?
  • Does your gaming Forum indicate any other reports of gaming issues?

Please also take a look at Riots' Troubleshooting Connection Issues.

Many thanks Smiley Happy
