Lag spike that never recovers

@Elocin - thank you, and I agree, that will have to be the next step. Reinstalling to a new SSD has showed no improvements. While looking into it as a network problem… I followed this post: Using WinMTR to troubleshoot lag issues inside SL dungeons/raids

I found two IPs that showed ESTABLISHED, so I WinMTR’d both:

C:\WINDOWS\system32>netstat -an | findstr 3724
TCP 192.168.2.55:51239 35.226.216.87:3724 TIME_WAIT
TCP 192.168.2.55:51435 24.105.32.63:3724 TIME_WAIT
TCP 192.168.2.55:51440 24.105.34.10:3724 ESTABLISHED
TCP 192.168.2.55:51513 35.226.216.87:3724 ESTABLISHED

For IP: 24.105.34.10

My understanding is 4616 packets were sent to the server, 4615 were received. Not bad???
