For your mouse double click issue, I have a g600 and ran into the same thing. It’s due to a teeny tiny copper plate in the switch degrading over time. I’m not confident in my soldering skills to swap out the whole switches, but I was able to buy some new switches for like $5, pop open the little plastic switch box, carefully pull out the little copper plate with tweezers, pop open the switch on my mouse, and carefully replace the little copper plate with the new one. Worked like a charm.
So in regards to specifically VR, I’m just going to make the blind assumption that your headset is a quest 2 or something along those lines. For the time being on campus, you might just want to consider running VR through a physical USB-C link cable rather than jumping through so many hoops on the router setup. A decent cable will run you like $20 US or how ever that translates to local. The quality of the connection is generally about the same as wireless, the main drawback is usually a wired link can’t put through enough energy to recharge you headset on top of the data transfer, so your battery will slowly drain over a few hours. There are also link cables that you can additionally plug your charger into so you don’t slowly run out of battery, but I think the build quality on those is often sketchy. Either way something to consider.
