Good evening all,
I have been trying for the last few nights, and failing miserably, to get the onboard WiFi working in Lithium on my Arka Book (super cheap 11.6" laptop).
From what I have been able to find out the chip is a Realtek RTL8723B, or at least that is what driver Macrium Rescue (bootable drive cloning/backup software that runs on WindowsPE) loads.
Lithium tells me there are WiFi networks available but when I try to connect to mine? It just times out. There are also no other WiFi points being detected in range as well as the signal from mine being incredibly weak (the router is 3ft away).
I've tested using Mint 20 Cinnamon & that works as it is supposed to, also working with Windows as mentioned above, but not in Lithium.
I've got the firmware-realtek package installed which I recently changed over to the backports edition with the same result, have since deleted the Realtek firmware directory and reverted to the original Lithium/Buster version.
I think the same chip drives the Bluetooth, which is working properly. inxi reports "No Device data found".
Can someone please help? This is driving me potty.

Is it this computer: https://www.lightning-computers.co.uk/p … b-ram-64gb ?
No info about wifi chipset.
You do not have link to the poducer?

Does really the command
inxi -N
return "No Device data found"? Then it is not detected, no wonder you can't connect to your router. Did you ran inxi under Mint?
On the page I found, there is no mention of RJ45-jack. It's not equipped with that? You installed with wifi?
You deleted Realteck firmware, instead of uninstalling?
I am not sure you know what you are doing...
There is often problems with RTL8723B...

Well, while I appreciate the reply, I'm not too keen on the tone of it.
Yes, inxi -N reports "Network: Message: No Device data found.", that doesn't, however, mean there is no wireless device as wireless points are still detected it is just impossible to connect to them as and when they show up.
Mint reports the same thing as BL/L under inxi.
No, there is no ethernet on this laptop, it's WiFi only. I installed by doing the bulk of the installation through VM and imaging it across using Macrium.
And yes, while I did just flat out delete the Realtek WiFi firmware directory I uninstalled and reinstalled firmware-realtek through apt afterwards.

^ so, is your problem SOLVED now?
If not, please https://forums.bunsenlabs.org/viewtopic.php?id=24 (add 'lsusb' output where applicable)

Unfortunately not! The problem is the same as it has always been, it "works", but it doesn't. Sees WiFi points but can't connect, also doesn't see anywhere near as many as it should.

I reset the syslog (backed up original) before running the commands mentioned in the other thread (sorry I didn't see those instructions to start with!) otherwise it would've been obscenely long. The above is a clean log from a fresh boot.
Thank you for your continued help.

Ok, so you knew, that it was not correct procedure to delete firmware, instead of uninstalling.
lspci, does not detect your wifichip.
lsusb, reports 0bda:b720, that is RTL8723BU.
You do not have an usb wifi dongle attached? If not, your wifi-card is wired to the usb-bus...
Your logs, report failure to load firmware for bluetooth but sucess for wifidriver. But the wifi-driver is not loaded acording to inxi...
You could make an workaround, by an usb wifi-dongle, known to work with linux.
If you want to continue, i recommend you try both firmware and kernel from backports.
You can investigate difference in logs and lsusb/lspci commands from Live Mint and Lithium.

First things first: Don't be root when you don't need to.
Looks like you're cursed with one of those realtek adapters that require a special driver.
I'm not sure Debian succeeded in finding the correct firmware for it.
Please repeat the lsusb command with the '-v' switch (you might need su privileges for that); from what I can see you either have rtl8723b or rtl8723bu.
A web search for the latter.
I'm no sure whether the official backported newer kernel would help here; can't hurt, I'd say.
PS:
I've got the firmware-realtek package installed which I recently changed over to the backports edition with the same result, have since deleted the Realtek firmware directory and reverted to the original Lithium/Buster version.
You're going to have a hard time fixing that - deleting files that were installed by apt, instead of uninstalling them.

For the RTL8723BU it should be in the Buster Realtek firmware package:
https://packages.debian.org/buster/firmware-realtek
If lsusb is not detecting it properly it may be an oddball revision not in the fw package yet.
And agreed on that: don't touch any fw blobs in the /lib/firmware directory, unless you know what you are doing

I have since tried Tails 4.11 and the WiFi is working on there, but strangely the Bluetooth isn't, doesn't detect a device at all.

Ahh my bad.
@Su1 do you have buster-backports enabled? You can try that version of the firmware-realtek package.

Installing the backports version with
sudo apt-get -t buster-backports install firmware-realtek
and then rebooting, gets the same results as the standard package.

The output of lsusb -v, as requested
The bit we're interested in:
Bus 001 Device 003: ID 0bda:b720 Realtek Semiconductor Corp.
(...)
idVendor 0x0bda Realtek Semiconductor Corp.
idProduct 0xb720
bcdDevice 2.00
iManufacturer 1 Realtek
iProduct 2 802.11n WLAN Adapter
iSerial 3 00e04c000001
The only unambiguous identifier is 0bda:b720. In the web searches I am doing on your behalf, I keep coming back to this repo. I think that's what you need to do.
It would appear that the firmware for rtl8723bu is in a Debian package, but not the driver.

By Jiminy! That's it!
Going down the git and dkms route for the driver package you linked to worked! I now have proper inbuilt WiFi as well as Bluetooth!
You, Sir, are a genius, gentleman and a scholar!
Marked as solved & will be scribbling down some notes on this one!

Despite the male chauvinism that sounds very flattering, but I hope you took your lesson from that: all I did was a few web searches. I tend to always include the search phrases (and engine, because no bubble is important) in my replies, for OP's benefit.

I appreciate "all you did" was web searches, but a search engine is useless without knowing what to search for and sometimes you need the human element to cut through some of the confusion.
It is a little ironic to me sometimes that the majority of IT forums, not just limited to Linux, are full of people being told to "Google it", which would in effect mean that if all every problem took was that? The forums themselves would be redundant.
Where as the human element from this problem has taught me a great many things in going forward, most importantly how to not only find but also utilise the information extracted from lspci/lsusb to find elusive hardware information, and surely that sharing and exchanging of knowledge is a major part of the Linux ethos, no?
I now have another card in my stack of Linux knowledge.
I stick by my thanks and compliment.

^ so, is your problem SOLVED now?
If not, please https://forums.bunsenlabs.org/viewtopic.php?id=24 (add 'lsusb' output where applicable)
That post should maybe be moved to Tutorials and add that som internal wificards shows up with lsusb?

You was invited by ohnonot to share some reflections, not to debate the Forum Rules "If you are seeking help, make sure to have done your fair share of homework to the best of your ability by searching the forums or the internet before wasting other's time."
No, the forum will never be obsolete, if members make some effort of reading, forum, net, homepage and own logs before posting. A lot of unnecessary posts can be avoided thus. And, no not every problem can be solved so. But, it sure will ease the solvingprocess. That is the thought. Not just a modern variant of RTFM (Read the fucking manual).
And, another no: It is no Good tell people to use a searching engine thats is tracking you. like Google Does. Quite many thinks about it ande use "internet Search" instead. "Search the net, forum and hopmepage", is good. "Search the net and forum and hopmepage", adding pointers and good advices, is even better. That is how it is here mostly.
But, I can agree, that the information here could be presented more structured and easier to find.
