Hi:

I'm not the best with the wifi stuff but I know how frustrating getting wireless to work can be.

Reading the output I see that you have a Realtek Card.

Code:
Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8821AE 802.11a
This link should help you get the driver installed for your wireless card.

http://askubuntu.com/questions/79721...with-rtl8821ae

Hope that helps.

Start by using your favourite search engine.

Plenty of (recent) hits - most Ubuntu/Debian or derivatives. But they seem to blame upstream. Several solutions from disabling power management to pulling a new driver and compiling from source.
Personally I would try the easy ones first before going to the compile - each new kernel will require a rebuild of the module. But if you must, you must.
FWIW, due to past issues like this (appalling support from the manufacturers) I avoid both Realtek and Broadcom when buying new kit. The Intel support of wifi has been good for years.

ondoho 03-19-2017 02:59 AM
it says clearly UNCLAIMED there for your realtek wifi.
usually requires some minor command-fu to
a) install the right driver
b) install the right firmware
c) sometimes both.

search for "ubuntu RTL8821AE" you should get answers.
let us know how it goes, more help is available.

Hi...

Just to be sure as to the nature of the problem, if you would, please open a terminal and run the command below...

Code:
wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info
Then post the results (or a link to them) in your next reply. This might give us some additional details. Thanks! :)

Regards...

Hi...

Thanks for posting the results. Here is at least one of the problems, if not the problem. Your wireless adapter is turned off at the computer (or hardware level.) It appears that your laptop brand and model (Lenovo-ideapad-Y700-15ACZ) doesn't have a physical switch to enable or disable the adapter, from what I see here and here. First, check the BIOS/UEFI to make sure it's enabled there and if so, see if the button combination mentioned in the articles linked to above enables the adapter, by any chance. I did find this patch, however, I don't think it's been included with Ubuntu 16.04's stock kernel. If the button combination doesn't work, you can contact Canonical to see if it's been added to any subsequent kernels or versions of Ubuntu or conduct some research to find out how the patch might be added to your current kernel.

If you're able to unblock the adapter, verify the status by running this command in the terminal...

Code:
rfkill list
All the entries should read "no." If so and your wireless still doesn't work after that, please run another diagnostic again and post the results. Thanks! :)

Regards...

Nope. No function keys or buttons found to turn on wireless. I used to see an options for check marking wireless in the dropdown list
in upper right corner (the two up and down arrows) - now that's not there.

Hi...

It looks like something happened, as these two entries have changed (compared to your previous results.)

Regards...

Birdman48 03-19-2017 07:04 PM
Dude I gave up and installed openSuse - not that it solved anything (Aardvark got me thinking I'd have better luck w/ openS). I'm struggling with Yast and Network Manager now to get that dang card recognized. We'll see. Thanks so far for the help. Will keep you posted on my progress w/ openSuse.

Birdman48,

Did you try using the method recommended in the link given by Ztcoracat in post #2?

Hi Birdman48...

Yes, I would agree. Give Ztcoracat's suggestion a try, hopefully it will also have a positive result concerning rfkill. :)

Regards...

Did try that about five times.
Now I may have increased the difficulty as openSuse seems less popular and hence there will be less support.

Just so I know, this problem seems to be one of getting the correct drivers working right? Are the drivers written by the vendor? If so there's probably no incentive for them to produce one. Maybe they're written/programmed by the Linux community in which case it's either very hard to do or I just cannot find them. Am I warm?

The best that I can tell you is that the driver had to be built and compiled for a Linux system.

Do you mean that you tried to install the driver five times?

It's the wifi device it seems. Not well supported in some cases. Drops a lot for some folks. Then you have to mess with power settings.
A few months ago someone made a patched driver to help fix the dropout issue.

Might be easier to get a small usb wifi adapter to make it work. Many are supported out of the box.
