Question

3 days ago I purchased an Acer One 14 L1410 laptop which comes with Realtek rtl8xxxu card, I have installed ubuntu. Everything is going fine but WiFi is not working well. I have searched everywhere but nothing solved my issue. My laptop have a function key for WiFi on and off. when I restart I have to first press Fn+F3 and again press fn+F3 then WiFi connects. But after suspend its again not showing any connection.i have updated my pc and now connection is permanentaly closed

Please edit your question to add the exact result of the terminal command: rfkill list all Welcome to Ask Ubuntu. — chili555, Jun 27 '17 at 12:23
When you first boot up? After you press Fn+F3 twice? After suspend? Is acer-wireless shown at all times? Any other *-wireless? phy0? It is very difficult to guess a solution without details. — chili555, Jun 27 '17 at 14:05
yes every time when bootup connection fails...i have to press twice FN+F3 to get a connection.after suspend the wifi disconnects and no network showed at all time — Ankit Mishra, Jun 27 '17 at 17:11
So you are confirming that rfkill list all shows acer-wireless and phy0 in all such cases and there are no blocks ever. Correct? — chili555, Jun 27 '17 at 18:35
yes...hey sir can you check himself .i am very new to linux i can give you my anydesk id.. — Ankit Mishra, Jun 27 '17 at 19:54
No, thanks. Next, let's check to see if the wireless driver is loaded at boot when it's not working. Find out with: lsmod | grep 8723 Again, on a fresh boot when the wireless is not working. — chili555, Jun 27 '17 at 20:23
i have done some reseach and found my driver is "rtl8xxxu"..and lsmod | grep 8xxx gives me output like this--- rtl8xxxu 126976 0 and mac80211 761856 1 rtlxxxu — Ankit Mishra, Jun 28 '17 at 09:04
May we see: lsmod | grep rtl and also: dmesg | grep rtl I actually suspect that the acer-wmi is not the problem. — chili555, Jun 28 '17 at 12:47
You had a wireless interface, wlx38a28c721f20 but, according to iwconfig, it went away. Let's try to find out why: dmesg | grep wlx — chili555, Jun 28 '17 at 13:15

Please open a terminal by pressing Ctrl + Alt + T and run:

gksudo gedit /etc/NetworkManager/NetworkManager.conf

Use nano or kate or leafpad if you don't have the text editor gedit. At the bottom of this file, copy and paste the following:

[device]
wifi.scan-rand-mac-address=no

The final result will look like this

[main]
plugins=ifupdown,keyfile

[ifupdown]
managed=false

[device]
wifi.scan-rand-mac-address=no

Proofread carefully, save and close the text editor and then run:

sudo service network-manager restart

Is there any improvement?

no there is no...i have to press the Fn + F4 twice to work again.. – Ankit Mishra Jun 28 '17 at 20:23
`sudo service network-manager restart dont work for me...and if i hit fn+f4 twice then it connects automatically – Ankit Mishra Jun 28 '17 at 20:34
Not Fn+F3 as before?? I'm confused. – chili555 Jun 28 '17 at 20:57
sorrry its a mistakeit is f4,,my pc has a function key to enable and disable the wifi by default its always on even at startup but wifi doesnt connect but if i disable the wifi using Fn + F4 and enable again using Fn+F4 ,,,wifi gets connected – Ankit Mishra Jun 28 '17 at 21:03
When you boot and it does not work, before you press anything, is the driver loaded? lsmod | grep rtl Or does it load after the two presses? – chili555 Jun 28 '17 at 21:07
yes driver is loaded all the time.. – Ankit Mishra Jun 28 '17 at 21:12
If you do: sudo rfkill block all && sleep1 && sudo rfkil unblock all Does it start without pressing any button? I may have an ugly hack. – chili555 Jun 28 '17 at 21:21
no it shows device is not ready...but again applying Fn+F4 twice...it connects – Ankit Mishra Jun 28 '17 at 21:29
Regrettably, I see nothing in your readings that is wrong and therefore fixable. I am very sorry that I have no other ideas or suggestions. – chili555 Jun 28 '17 at 21:33
what does it mean lo--no wireless extension when we check in iwconfig....also nmcli d shows that lo is not managed by network manager – Ankit Mishra Jun 28 '17 at 21:38
lo - no wireless extensions means that it, the loopback interface, is not a wireless interface. That is why it is not managed by NM; it does not connect outside the computer itself. – chili555 Jun 28 '17 at 22:32
in (lshw | grep 8xxx) firmware=N/A.....DOES IT MAKE SENSE IN ERROR ?? – Ankit Mishra Jun 29 '17 at 05:01
Your dmesg above clearly shows that firmware was loaded. – chili555 Jun 29 '17 at 11:47
you mean..it is not a error ??..HOW CAN I FIND A ERROR ,I MEAN WHAT IS WRONG WITH MY PC ?...IS THERE ANY LOG COMMAND ? – Ankit Mishra Jun 30 '17 at 13:17

I have exactly the same problem as this. I have replaced the drivers with r8168-dkms_8.044.02-2_all.deb after which at least the cable ethernet works properly, but the wi-fi deactivates at every shut-down and has to be physically turned off and on again before it will connect.

Edit: After much research, I found the answer. The key was in lsusb: ID 0bda:b720. The 'b720' refers to either the rtl8723au or bu chipset.

ref: sites.google.com/site/easylinuxtipsproject/reserve-7

This machine uses the rtl8723bu chip and there is a driver by lwfinger here:

https://github.com/lwfinger/rtl8723bu

and a dkms version by James Buren can be found here:
