Ron,<br>
<br>
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).<br>
<br>
Thanks.<br>
Pablo.</font></font><br>

<br>
<br>
I am building a data-logger for a 'seismograph' on a RPI-2 running
Centos 7.
<br>
<br>
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.
<br>
<br>
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
<br>
on a laptop, no issues at all.
<br>
<br>
any ideas? (I put some of the details below, it's wlan1 I am
trying to make work)
<br>
9Not running anything IPV6, so don't know why that module was
loaded.)
<br>
<br>
thanks,
<br>
<br>
Ron
