I bought the official wireless card from them at the same time as the board. However since kernel 4.13.0, wifi as provided via mwifiex_pcie module stopped working. I don't have much info on the userspace side, as all that happens is the wireless interface is never brought up and stays in 'NO-CARRIER'  state according to 'ip a'. However on kernel side, I hope I have some info that are more useful ! :) This was logged via systemd-journald with debug turned on in mwifiex driver. I am willing to try anything to get this kernel working, as it's a lts kernel contrary to 4.12.12 on which I'm forced to run for now. https://gist.githubusercontent.com/mk-fg/27c2505fd3bffcf0af87777aaafb71fe/raw/fda70ff9f8eaab248a104e03922323cf2f4754bf/tmp.txt I hope these info will be useful in debugging. I'm new to all these kernel stuff, so I may have posted to the wrong place or in a wrong way, if so, please let me know. Thanks in advance -- Ellie Reeves
