Need some troubleshooting help with r6400v2 and linux

appears to have been a channel issue.  The router was defaulting to something like channel 153 and channel 11.  I reconfigured it to channel 2 for 2.4ghz and 116(dfs) for 5ghz and now I'm seeing appropriate connection speeds.  My 5G is actually showing the 100M up and down that I pay for.. 

My android shows 70+ (not bad for those small mobile anenna's)

My MBP shows 75ish (the android and the mbp are still on 2.4Ghz, I see similar on my ubuntu as well on 2.4Ghz)


All of this after a reset to factory, down grade firmware (no change), reset to factory, upgrade firmware, reset to factory (again, no change), get my configs on there, and then I messed with the channels (because who doesn't do that first.. duh.. sall good, shes working right now)
