Today bought Wi-Fi USB adapter D-Link DWA-131. It does not worked "out of box". Tried solution from Install DWA-131 WiFi dongle driver under Ubuntu 14.04.4 - does not helped too.

Will be very gratefull for any help on this trouble.

UPD: Here is diagnostic output requested by chili555:

Solution

You have several possibly conflicting drivers loaded. The driver rtl8xxxu should drive the USB well. Let's blacklist all others and see if the USB now works as expected. From the terminal:

sudo -i
echo "blacklist rtl8188ee"  >>  /etc/modprobe.d/blacklist.conf
echo "blacklist 8192eu"  >>  /etc/modprobe.d/blacklist.conf
exit

Reboot and tell us if there is any improvement.

Please edit your question to add the result of three terminal commands: lsmod | grep rtl and also: dmesg | grep wlx and also: rfkill list all

@chili555, done

[chili555]

Hard blocked:yes usually means that the airplane mode switch is set to disable the wireless radio. Please find it and switch it on. We will still have a step or two to take, but nothing works properly with the radio turned off.

@chili555, strange, but according to KDE interface, airplane mode was switched off... Retoggled it to make it off again, but rfkill shows same result. Tried hardware key with airplane sign, it makes soft block enabled or disabled, but does nothing with hardware block. Also - what if this phy0 refers to integral Wi-Fi card in my laptop which I also could not get to work?

[Jeremy31]

What computer manufacturer and model?

[Dmitriy Vinokurov]

@chili555, sorry, updated post, I forgotten to insert USB stick before taking output :( My bad... Late night here...

[chili555]

I'm sure that the internal doesn't work because of the hard block as well. @Jeremy31 is on the right track. Can you run: lsmod and paste the result here and give us the link? paste.ubuntu.com Wouldn't you really rather fix the internal?

[Dmitriy Vinokurov]

@chili555, here is my lsmod - paste.ubuntu.com/p/cNRNN4KDgk

[chili555]

An HP computer, evidently. Very tricky. For the time being, let's try to coax the USB to life. Please see my answer in a few minutes:

Unrelated to this question, but I have something you might find useful for your solve all realtek problems superanswer with luis. Couldn't ping you in chat b/c you haven't been there in a while.

@chili555 I gave up with this issue and missed your answer, but now after years I returned to it with fresh installed Ubuntu on same old laptop, blacklisted rtl8188ee and Wi-Fi works now, thank you very much!
