The XBVR server is connected to the router through Ethernet and I double checked again that my Quest is using 5Ghz WiFi connection. Still having the same speed discrepancy from inside the HereSphere app. The file I was having issues with was roughly 30000Kbps (not sure I'd even want to store a 200Mbps bitrate file). Might do a reset of the Quest 2 and reinstall Heresphere to check if there's just some random issue.
