Wifi connection troubleshooting

q4osteam · 2023-11-09 11:02

Tip 1 - Trinity desktop:
Use built-in TDE wifi manager
Right click on the network manager icon in system tray > edit connections > select wireless connection > click edit connection button > go through all steps of the guide and enter proper values > until you get to the check box that says "Automatically Connect" > then click "Connect and Save".

Tip 2 - Plasma, Trinity and other desktops:
Use desktop environment independent tool "nmtui"
Another way is to use terminal tool "nmtui", what is desktop environment independent. So run in any terminal:
$ nmtui
and setup your wifi

Tip 3 - Trinity desktop:
Install external advanced network manager applet
- Install from repositories:
$ sudo apt install network-manager-applet
- Reboot
- Run:
$ nm-applet
- Find network manager applet in the system tray > right click > configure > configure desired networks

Tip 4 - Request a help on the forum:
If you request a wifi related help, it would be appropriate to provide output of the following terminal command:
$ inxi -SMCGxn
Moreover, you should provide debug info as described here https://www.q4os.org/forum/viewtopic.php?id=3502

Might I suggest that for ANY wifi connection issue it is mandatory for the user to provide the output of inxi -SMCGxn before it is answered.
Without that one has no idea what sort of can of worms one is dealing with.

I am new to Q4os so excuse me if I sound uninformed. I am trying to set up aan Archer T2U plus usb adator for Wifi. I cannot find out how to enable it. The install disc does not execute at start up. It may be set for Windows or Mac. I know it can be configured for Mint linx or Ubuntu. Any suggestions? Thanks!

Driver support for this device in Debian is a mixed bag, but take a look at this and read it all the way through,

https://docs.alfa.com.tw/Support/Linux/RTL8812AU/

To be honest youd be better off getting another device that has native Linux support as this product clearly states it doesnt support Linux.

Noob's question...
At https://easylinuxtipsproject.blogspot.c … .html#ID10

"Speed up your wireless internet by disabling the WiFi power management"

Can it use in Q4OS TDE?

Use iwconfig and see whether your wifi chipset power management is on/ off or doesnt show anything. You really should post this question in a separate thread for better visibility. It should work but is it really necessary?

i am having similar issues. This is the second time this has happened and a reboot before solved the issue. Wireless is not available...i see all the settings no matter what manager i use, but i cannot enable it....
Here is the output from the commands that have been suggested...

I am also new to Q4OS.
The system was running great until I installed Proton VPN.
The WIFI is now disabled, but the wired connection (enp0s25) is okay.
I tried the Edit connections, but no change.
I tried nmtui, but no change.

I also lost the setup for firefox and thunderbird, but I have reinstalled okay.
I tried to find the ProtonVPN package with Synaptic to remove it, but ProtonVPN was not found.
The WIFI New connection menu shows 2 Unknown connections (wlp3s0) (enp0s25) and a VPN connection.
The WIFI deactivate menu shows a connection called lo and won't respond to enable WIFI.
The notification settings shown a VPN banner notification, a VPN connection attempt failed
and a wireless network disappeared.
The wireless connection (wlp3s0) is disabled.

Thx
