Wifi problem

I have just installed Q4OS on an old laptop and am having exactly the same problems as member Darega 0n 13/01/2021 which unfortunately was not solved.

A message comes up saying that SSID is not found despite it appearing in the list of available networks.

I was able to connect through wifi to the router earlier in the week when I was trying out Lubuntu and Xubuntu distros on this machine.

I attach the suggested Konsole outputs from my machine.

Re: Wifi problem

I once had problems with an RTL8192cu and had to use a chipset driver from github, according to the owner this is now deprecated and shouldn't be needed but might be worth a try.

The one I used.

There is also this one which was reported to be easier to install, YMMV
https://github.com/0xBADEAFFE/rt8192cu_dkms

NOTE: You will likely need to reboot after installation to ensure everything works properly.

Re: Wifi problem

Well, I see both issues, yours and darega's, (though a bit different since you're using a 64 bit OS and darega's is 32) happen while using the TDE version, have you tried with KDE? If the problem doesn't occur, then it's a TDE issue. I think your PC can handle KDE just fine, you should give a try in a live USB stick.

Re: Wifi problem

You could also try to connect to wifi in console to exclude possible Trinity issue. Do not login to TDE, switch to console and run:
$ nmtui
connect to a wifi network and post a feedback.

Thanks Tolkem

I came to Q4OS because I saw a post stating that the TDE version was the best Linux version to work on this particular machine. I did try the KDE version you mentioned (I presume that's the Plasma desktop) but it froze several times so I removed it.

Thanks for your help but you have lost me.

I am pretty much a Linux newbie and can't see how I avoid logging into TDE which seems to load automatically.
I don't have a password set (tho' not sure if that's relevant).

Really? Did you use Q4OS Plasma version? Hmmm... That's weird, I use KDE Plasma and my laptop has an AMD-APU too, RAM is only 2GB, it works just fine. In your inxi output, unless I'm wrong, says your PC's RAM  is around 6GB, did I get that wrong? That's what I thought it could handle Q4OS KDE just fine. Maybe it's a Toshiba thing, mine's HP.
Open the terminal, konsole, and type this:

sudo ifup wlp6s0

Press enter and type your password when asked. This will try to bring your wireless interface up. If you get any error messages in konsole, copy those and paste  here in your reply.

Here we go:

Unknown interface... Is that your machine's wireless interface name? It's the one shown in the inxi output:

Network:
  Device-1: Realtek RTL8188CE 802.11b/g/n WiFi Adapter driver: rtl8192ce
  IF: wlp6s0 state: down mac: 20:16:d8:84:41:76

If it's not, that explains the unknown interface error. Make sure it is, if it's not, then change wlp6s0 for the actual name and re-run the command, copy/paste whatever error you get in your reply.

Re: Wifi problem

As a footnote to this that might be of interest I've encountered similar circumstances with built in cards. Now I bypass these and use a D-Link USB WiFi adapter instead which works with every combination I've so far tried it with.

Re: Wifi problem

Here is a modified driver for your Realtek RTL8188CE 802.11b/g/n WiFi Adapter.
https://github.com/FreedomBen/rtl8188ce-linux-driver
This modified version of the RealTek WiFi driver fixes some issues with RealTek cards on Linux.
But, you have to install it by yourself. In that page, there is an explanation how to install it. But be careful. Wrong installation can break your system.
So read carefully what is written there, then try automatic installation first. But keep in mind, that you will have to recompile driver after kernel update.
Here is a thread on Linux Mint forum, where the author successfully installed driver: https://forums.linuxmint.com/viewtopic. … f7#p899113

If everything fails
Then, you will have to buy this USB Wi-Fi adapter. I am using three of them. All are working perfectly on Linux.

Before asking for help please read this topic: https://www.q4os.org/forum/viewtopic.php?id=3502   If you have problems with WiFi network, try to install the Network Manager using Q4OS Software Centre.
