Pretty much every time I play classic anniversary realms (retail too but not as bad) I get frequent latency spikes where the game will completely freeze up for usually ~5 sec, sometimes as long as 20 sec.
Here is the weird part. I started running WinMTR to 20.66.110.161 to try and determine where the slowness is and the issue goes away completely. It’s at the point where I just run it constantly because if I dont the game is unplayable.
What could possibly be causing latency that running WinMTR would solve it completely? It seems like the connection sleeps without a constant ping or something.
It sounds like you’re playing on wifi. The extra throughput is likely making the router or nic keep a stronger signal(probably through beamforming or something like that, maybe channel hopping or channel width. Sometimes certain combinations will result in less maximum bandwidth, but you’ll have a stronger connection) and is resulting in either less packet loss for WoW.
I’ll give turning that setting off a try. I’m on a LAN on a desktop though with traffic going through it, I wouldn’t expect windows to turn it off, but you never know I guess, worth a try.
Edit: It doesn’t look like turning the power management setting off helped at all.
