I have a Lenovo Ideapad 510 and upon installing 17.10 I've been having consistent wifi issues.

Primary the randomly dropping the wifi connection and the problems associated with that.

I've tried multiple "fixes" but none of them work, I even purchased a USB wifi adapter to try and bypass the issue but to no avail.

Does anyone have a fix?

Edit #1:

Running nlspci -knn | grep Net -A3 gives the following output:

Please edit your question and add output of lspci -knn | grep Net -A3 terminal command. Replace lspci with lsusb if you want to troubleshoot the new USB dongle. That said, the symptoms occuring with two very different chipset (supposedly) suggests you have wrong wireless encryption settings at the router. – MichaelBay Nov 3 '17 at 0:21

Yes I have the same laptop and had this issue with 16.04, 17.04 and 17.10 versions of ubuntu. The following solution fixed mine.

sudo apt-get install -y linux-headers-generic build-essential git
git clone http://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
sudo modprobe rtl8821ae

and restart. Hope this fix the issue.

So what commands do I have to run to install this? I got to "cd rtlwifi_new" before I got lost. (Sorry, linux newbie here) – USELESS Nov 3 '17 at 2:08
    
These are the commands in the greyed zone. Enter one by one – Habeel Khan Nov 3 '17 at 2:09
