I need some help with Vive tracker (2018) tracking issues. I use 3 trackers along with the Index for full body tracking. I have tracking issues on all 3 trackers and am trying to troubleshoot. I've done all of the usual troubleshooting steps....no reflective surfaces, turning off WiFi, changing USB ports (2.0, 3.0, 3.1), testing one tracker at a time, swapping dongles, etc....I also purchased the Inateck USB 3.0 PCI-E card. But so far nothing has fixed the tracking issues. I'm trying different locations for dongle placement now. I made sure they are at least 3 feet away from the PC. But does it matter where the dongles are placed elevation wise? The trackers are used on my waist and feet, so would it benefit to have the dongles on the ground?
