Acer Aspire E 14 - no WLAN

Hi,

i try to install latest stable Majaro on a Acer Aspire E 14 (E5-411-P23Y). I cant manage to get Wifi working. Do i need to install some proprietary driver? For now i work from a USB stick, does this make a difference to a full install?

Here some more info:

Everything else seems to work. Any help is welcome.

I hate to have to be the one to break it to you, but that adapter is often next to impossible to get working properly.

I'll post a link for you to try installing the broadcom-wl-dkms driver. However, I wouldn't have high hopes of getting it working properly. Some do manage to get it working, but with very poor connectivity.

Follow these steps to hopefully resolve your broadcom driver issues.

Good luck.

I have an Acer Swift laptop with the same network device. What distro "flavor" are you trying to install, out of curiosity?

I have installed Manjaro Gnome, Budgie and KDE on it, currently KDE (installed about a week ago,) and have had no issues, excellent internet speeds.

Edit to add: BTW, Acer's have a function usually on their laptop keyboard to enable/disable wifi. Make sure this is enabled. :wink:

I'm not saying it doesn't happen, but if you search the forum for your adapter you will find many issues, with very few positive resolutions for this adapter. For some reason there are a few here and there that don't seem to have issues with this adapter, but they are in the vast minority.

That is why I included the link to install the broadcom-wl-dkms driver. It is possible that this user could be one of the lucky ones (as you are) to get it working properly.

If you don't mind me asking, which kernel are you running. It's possible new improvements in the kernel have improved this adapters usability recently.

Yep, totally not discrediting your points. As you say, I may be just one of the lucky subset.

I am currently running 4.19 kernel under KDE. When I was on Gnome, I used both the 4.19 and 5.0, both again worked well.

Thanks for the hints. Guess what, after installation, the WLAN started working without further configurations. :+1:

However, not all is perfect. Now, occasionally, the mouse stops working for left mouse clicks which makes the GUI almost unusable. Both for touchpad and external mouse. I'm using XFCE and kernel 4.19.32-1. I will look into this issue and eventually open a new question.
