Link speed is 340mbps max note 5 in the same 5ghz AC network is always like should be , 866mbps , don't know if that could be fix with a software update, clear cache don't resolved the problem, or if i get a damage phone, first batch
I had mentiond this on different thread. Note 7 has low signal strength. I have not seen it went above 300 while Note 5, and other family phone got 700-866 at the very same location.
