PCE-AC88 Can see Networks But won't Connect

[kavidey]

I just got a used PCE-AC88. It works very well with Windows 10, but I had a lot of trouble with ubuntu. After a few hours of testing and searching, this https://rhees.nl/2017/03/10/HOWTO-in...Debian-Jessie/ tutorial let my card see networks. If I try and connect to one, ubuntu tries for a few seconds and then just disconnects. I used a completely fresh install of ubuntu 16.04.4.

Try to avoid instructions which are built upon backported software. Better to begin with a fresh install of a recent release, that is 17.10.1 or 18.04 (beta).

I installed Ubuntu 17.10 and ran lshw -C network. Ubuntu could detect that the wireless device was plugged and the manufacturer, but the device was unclaimed. (The other wifi device in the output is built into my motherboard)

Good beginning.

There are many users here knowing more than me about wifi connections. In order to attract their attention I suggest that you click the report button and ask a moderator to move your post to the networking forum. After that please read the sticky notes in that forum and follow the instructions.

Thread moved to Networking & Wireless, a more appropriate forum.

Please run the wireless script from the sticky thread and show the outputs

I ran the wireless script http://paste.ubuntu.com/p/xbkjmCGJ67/ was the result.

Your realtek internal should work after

sudo apt-get install dkms git build-essential
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6

Reboot

Make sure Secure Boot is disabled

Thank you for that fix. The only issue is that the realtek internal is much slower that the broadcom device. Is there any way to get the broadcom device working too?

[jeremy31]

Try

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*

Reboot and see if the broadcom works
