Slugontharug,
The previous posters identified your issue. You’re suffering packet loss between your modem and router. If you’re on wifi, I recommend ethernet. If you’ve been having problems for as long as you mentioned, your issue would have been unrelated to that thread. The issues in that thread started in november and were hit and miss thereafter.
In your specific case we see evidence of router or wifi malfunction. Until you fix this, the issue will continue. You can try power cycling the router/modem and use an ethernet cable if that fails. If even that doesn’t work replace the router and it should fix it.
If you still have problems after resolving the packet loss with the steps above, reply back with a new WinMTR which catches the problem. If you want more information on why this may be only affecting us, check this thread.
If all you are experiencing is ~90 MS average latency, this is expected latency from your house. You’re taking the most efficient route possible with our peers to the servers you’re going to.
