#19799: Apple drops off 5ghz network on Archer C7 on CC
----------------------+----------------------------------
 Reporter:  hendry    |      Owner:  developers
     Type:  defect    |     Status:  new
 Priority:  normal    |  Milestone:  Chaos Calmer (trunk)
Component:  packages  |    Version:  Trunk
 Keywords:  apple     |
----------------------+----------------------------------
 I successfully setup 15.05-rc1 on my Archer C7. The IRC channel was
 helpful and I think `opkg install kmod-ath10k` got my 5ghz going.


 I'm unsure about the channel and txpower values:

 Especially since luci, the Web interface seemed unresponsive. I'm in
 Singapore btw.


 The problem is my Archlinux machine behaves fine. But my wife's Apple MBP
 2013 model doesn't. Same issue with my iPhone6. It just drops off the 5ghz
 and favours my other 2.4Ghz AP, where it's stable.

 MBP wireless diagnostics:

 I was trying to get my iPhone6 to join it, but it won't do so.
