How to get Wi-Fi on new installation of Linux Mint Cinnamon 64-bit

Post by TimNewbie »

Hi there. Last night I downloaded Linux Mint 19.3 cinnamon 64-bit. I have no idea about coding, et cetera, not that smart computer wise!

I’m doing the set up and I’m told there is no Internet connection. I’m trying to connect to my home Wi-Fi but have no idea how to go about it. Tutorial said to go to drivermanager but when I click on that I just get a blank screen within that box.
I’ve used an ethernet cable to update, add software, as directed but no idea how to use wireless!
Please help?
Researching the Internet I found Ununtu doesn’t accept the RTL8723DE driver that I have but after following the instructions in this website, http://ubuntuhandbook.org/index.php/201 ... ntu-18-04/ the pseudo mod probe commands at the end said it could not insert RTL8723DE

The Driver Manager is empty, because it's no longer necessary to install it. It's already installed.

To connect wirelessly:
1. Go to the System Tray located in the lower right corner of your screen & click the Ethernet connection icon.

2. Make certain that the "Enable Wi-Fi" option is checked. Click the SSID of your router.

3. Enter your password. Click "Connect".

Thank you for your reply. It’s a realtek RTL8723DE
Driver Which I’ve read can be a problem. Would it still work with what you suggest?

The suggestions above won't break anything, so "try it. What the "Hades" have you got to lose?" (tongue-in-cheek). We're not talking about Hydroxycloroquine.

If it doesn't work, someone will instruct you about diagnostic tests to pinpoint the source of the problem.

The system tray doesn’t have the same symbol like you are showing in your picture. Mine is a box over two boxes and it says connected to the Wired network when I highlight it

Yes, in my post above, I did all the commands until I started getting error messages in the terminal.

The interesting thing is my Wi-Fi symbol has now come on saying I’m connected to the wireless Internet but when I click on the website it says it can’t connect to the server, check your network connection! Even though it is showing it is connected to my home network!

Were you able to complete the last 3 commands starting with 'make'? If not, try that.

You’re a star, it is working! Thank you so much!
Could I use your expertise for one more thing please? Or do I have to open another thread? It’s just that I want to remove the vertical lines on a Thunderbird reply email. Basically when I do reply, for some reason there are vertical lines down either side of the original email and I would like to get rid of them please?

Probably best to start a new thread for that. I've never used Thunderbird, so not familiar with it at all.

Just a few reminders. As that site said, don't update the kernel or you will lose the driver.

Also, IF the driver gives you a problem, do #2 here:

Thank you, I will try and remember. I don’t know what the kernel is!

Well, put simply, the kernel is what makes LM run. If the kernel should ever get updated, just do #8 there again to get the wifi driver back.

Ah ok thanks. Should I look at finding a different driver for my type of computer which is compatible with Linux?

You should be fine. If it isn't broke, don't fix it. :lol:
