Vive trackers for full body no longer working.

I have: 3 2.0 vive trackers, 2 HTC vive base stations, and a valve index with the knuckles.

My full body tracking use to work just fine but suddenly they won't track at all and will not connect to the dongels. Sometimes I can get two of them to connect but the 3rd will never connect so my full body tracking doesn't work. I bought one new dongle and still nothing. I am unsure of what to do now I have dabbled a bit in other trouble shooting things but they never work.

(I have tried to track them one at a time but they just won't track at all sometimes. Like I can get one to track every time but getting 2 is a hassle and getting the 3rd is impossible.)
