Hello Ron,
Before we start with the wifi, I'd like to ask about your kernel because I don't recognize it as a centos kernel (centos for arm has used the 3 latest LTS, 4.4, 4.9 and 4.14).
Thanks. Pablo.

Hello,
I am building a data-logger for a 'seismograph' on a RPI-2 running Centos 7.
Wireless is working, with another wireless usb adapter, but since this one is going to sit in a barn, I need a longer range wifi antenna.
The OS sees the device, and ifconfig shows a MAC address, but somehow it doesn't seem to come up. It does work on "regular" Centos 6, running on a laptop, no issues at all.
any ideas? (I put some of the details below, it's wlan1 I am trying to make work) 9Not running anything IPV6, so don't know why that module was loaded.)
thanks,
Ron
