Everyone ping jumping

I’m in games now recently where the ping of everyone’s is jumping to 100 plus then back to 20 or 30, then back to 100 plus.

Never happened before. My ping normally sits at a steady 20 to 30 ping.

I was having this issue and hard wired my connection. Ping is solid now

I don’t have an Ethernet cable long enough, I need to get one then.

Thing is I’ve never had this issue up until recently, like 2 days ago.
