Your average wifi card is omnidirectional signal strength 6db. Well, this is where routers have you beat. So you have your heat managed, but you're still only getting 100 Mbps and spikes of latency. You might say sure, I'll just buy one with a heatsink or I already have one with a heatsink but. The cheap cards will got hot over the continuous input/output of heavy use. The virtual desktop app community has advised against trying to do this for awhile but full-throated explanations are in short supply and it is usually just authoritative assertion and that sort of thing doesn't cut it for a lot of people. Having a hotspot work as well or better than a router is rare for most people. I feel that if you have to spend money anyway, and are trying to choose between a router and a wifi card, your money is better spent on a router. If you already have a hotspot and that hotspot works? Great! Maybe you picked a hidden gem of a card, maybe your environment is conducive to hotspots. I'm just going to try to save some people the frustration and money here, by actually explaining why you cannot use a hotspot effectively to play airlink.

The only thing I'd add in, that wasn't in the video, is that I'd disable packet coalescing in the wi-fi adapter settings. I only still have the Fenvi and it works great after following the video directions. I want to add, I tried EDUP, Fenvi and killer network cards. If wifi hotspot didn't work for you in the past, maybe this video will help you. Disabling this service while playing eliminates that.

Further, there are lag spikes caused by W10 checking into new wifi sources in the backround. For whatever reason, this fixes the throttling. The fix, silly as it is, is to connect a mobile phone to the hotspot, then disconnect the mobile phone, the connect the oculus quest headset and start playing. Something throttles the oculus quest connection speed when you connect it to the hotspot under w10. the real culprit here is some weirdness in either microsoft or intel's court. Yeah, you could overheat a usb dongle as a hotspot, but otherwise. Edit: this information is partially wrong.
