fwiw...when I went hardwired on my pi, I did get a better hashrate and a bit higher freq than on wifi, but I couldn't turn it up all the way like I can on my Win10 desktop before running into issues. I think it was around 675MHz when cgminer would freak out and the miner would drop back down to 200MHz and try climbing up again. I tried different boost settings, but nothing helped. I'm back on my Win10 machine at 763Mhz and 1.020Th/s.

I know some other users are reporting that things are OK on their pi's, but when I look at the pools stats for the same pool we're on, I'm consistently hashing 100Gh/s more with the settings I'm able to run on my Windows box. I'm not sure they're turned up all the way on their pi's.
