Rainbow Six Random high ping
Rainbow Six Random high ping
There should be no other activity using the Internet. If a download was occurring, it would have completed by now. I've experienced this problem for the last couple of hours, and my ping remains very high. Also, I verified the ping between my ISP and another network, which is 57 ms—acceptable but not ideal.
Restart the router and observe the outcome. If this is the only scenario, try another activity now and revisit later.
