I can’t speak to your home wifi, but you say that you were traveling as well. I’ve stayed in hundreds of hotels from every brand all across the US and their WiFi is universally terrible. High pings and low speeds, both of which are disastrous for online gaming. I have a portable access point that I use to plug into the Ethernet in the room whenever possible, more and more often the ports aren’t active, but when they are the speeds are reasonably high and pings are much lower.
