To paraphrase Tennyson, 'tis better to have tried and failed than never to have tried at all.

In my post #6 above, I opine that the wireless driver is now available; we only need to original poster to compile it and report.

I actually found the github source code while browsing the Arch Linux forums and a poster said the module works but didn't state what kernel was being used https://bbs.archlinux.org/viewtopic.php?id=227376

Sorry for the late reply.

Indeed this works out. I retreated to use a wifi USB meanwhile. Finally, feel relieved.

**simoncks1994** · July 16th, 2017

After some check, I discover that the connection only lasts for the first minute. During that minute or so, I can connect to google. After so, the WiFi label shows connected with full strength although network is not reachable.
I am using PrivateInternetAccess and KillSwitch is disabled so I don't think it is relevant. I have two user accounts. One of them has its home directory encrypted. WiFi does not work in both accounts.

Meanwhile, there is new update in lshw

Code:

Any clues in the log?

Code:

cat /var/log/syslog | grep -i -e wlp -e dns

If the output is null or sparse, also try:

Code:

cat /var/log/syslog.1 | grep -i -e wlp -e dns

Code:

cat /var/log/syslog.1 | grep -i -e wlp -e dns

gives the following response -

I cannot compile the github driver here, so no statement on this.

On the Realtek HP I only find the Win drivers:

http://www.realtek.com.tw/downloads/...&GetDown=false

Maybe trying Ndiswrapper?!

Edit: Please also show

Code:

dmesg | grep rtl

Thanks everyone. I am happy to provide more information.
