Hi Felix, Jonas,
While playing with my AXS101 board and USB WI-Fi dongles I bumped in
a couple of issues. Fortunately I found at least one dongle that
works quite nice. That's TP-Link TL-WN721N (or its WN722N sibling)
which is based on Atheros AR9271 chip even though it did require
one unexpected tweak.
For starters I just selected "kmod-ath9k-htc" in menuconfig and
on boot saw USB device recognized, its firmware was loaded,
"wifi detect" recognized it as well, see log below.
But then "wlan0" interface was not created on "wifi" command.
After some googling I somehow came to resolution that "hostapd"
package installation fixes this problem. And indeed once I got
image rebuilt with "CONFIG_PACKAGE_hostapd=y" all worked as expected
and I was able to use my board as a Wi-Fi access point.
So the question is if this is expected (requirement for "hostapd")
[for "ath9k_htc"]?
Another minor issue is that USB dongle gets recognized a bit late
so that automatic "wifi detect" gets already executed and
"/etc/config/wireless" isn't created. That requires manual execution of
"wifi detect > /etc/config/wireless". Essentially extending delay in
"package/base-files/files/etc/init.d/boot" makes a difference:
---------------------->8-------------------
# allow wifi modules time to settle
sleep 15 # instead of 1
---------------------->8-------------------
but I'm not sure if we want to do that change for all devices.
Then if there's a better way to make auto population of
"/etc/config/wireless"?
