  1. After some research, I found a newer wifi firmware by QCA.
    Please help to try it. download it with web browser by click:
    DownGit

Then upload it to /lib/firmware/IPQ6018 directory, and unzip by

cd /lib/firmware/IPQ6018/
unzip -jo WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1.zip
rm -f WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1.zip
sync
reboot

Seems this is a compatiblilty issue with Roku TV.
