New Computer Problems With Mint 19.3
« on: March 09, 2020, 11:01:02 am »
Bit of help needed please. I have been using Mint  for about 10 years now. I recently bought a new laptop and installed 19.3 over the Win 10 and I can't access the internet using wifi, however, Xubuntu connects with no problem. There are other issues like screen backlight commands won't work and all the desk top icons and fonts are very small, though these are low priority at the moment. I like the Xubuntu but I would like to use 19.3 as an option - any ideas Please?

I have taken this s/shot if it helps:

Though I use Linux I am not very tech savvy so a simple explanation would be appreciated! Many thanks.

P.S. Ubuntu also will not auto connect either.

Hi Graham.

Try starting a terminal session and entering:
Code: [Select]
iwlist scan
This should list all the nearby routers.  If your router is listed with a decent signal then that should provide a clue.
If it doesn't list any routers then that provides an even bigger clue.

Thanks Keith - This is the result, doesn't mean a lot to me I'm afraid, though the number of sig strength bars is only 2. Thanks, Graham.

I know I'm being pedantic, but can you confirm that "PLUSNET-3SJW" is your router?  And did you get any others?

The signal quality of 40/70 should be fine but the signal strength of -70dBm is tiny.  Mine is -47dBm  (200 times bigger).  A signal strength of -70dBm means 10^-10Watts.
On the other hand, two signal bars ought to be readable. 

Can you decrease the distance between PC and router?
Are your Ubuntu 18 & Xubuntu machines at the same distance from the router as your Mint laptop? 
Can you use Ethernet?

Hi Keith
This the result from my old comp, Mint 19.3, sitting right next to my new comp - different result. Signal strength showing 5 bars (86%).  Yes it is my router and the wireless  desktop, win 10 has a good signal. So it looks like the new comp is lacking signal strength for some reason? Too far away to use an ethernet.

Yes, it certainly looks like a problem with your new laptop.  The specifications of the machines and the reports on the web (https://browser.geekbench.com/v4/cpu/15197553) look very good to me (although I'm no expert!), so it's very disappointing to have such poor wifi reception. 

If no-one else has any advice to give then a last-ditch solution might be to replace the wifi receiver.  Not too expensive but a pain to do - I've done it once.  If you decide to go that route, then you'll probably find a YouTube demonstration of how to do it.  What's the Laptop make, Graham?

Thanks Keith, it's an UltraNote series 15.6 Matte made by PC Specialist in Wakefield. I suspect it is 'tuned' to Win 10 so I think I shall have to have a word with them. As I said Xubuntu is working ok on it but I may have to reconcile it by reloading win 10.....hmmmm.

Ah..... if Xubuntu wifi is working on it (I thought Xubuntu was on a different machine) then the problem does not lie with the wifi receiver, but with the Mint installation. 
What is the output from the iwlist scan command in Xubuntu?

Ok, the first iwlist scan output was from Xubuntu on my new comp, the second iwlist scan was from Mint 19.3 on my old laptop situated next to the new machine. It seems that this new laptop has been built to be 'compatible' to ms win only - could it be a driver problem?

EDIT: The output of iwlist scan on Mint 19.3 running of a USB stick on the new machine says:

Sorry;  I am very confused. 
You say that "the first iwlist scan output was from Xubuntu on my new comp" but your first post says "I recently bought a new laptop and installed (Mint) 19.3 over the Win 10".
Can we start again?
Please post the output from the following commands on  just your new machine that you want to have Mint 19 running on:
Code: [Select]
inxi -Fx
Code: [Select]
iwlist scan

Apologies for the confusion, I put 19.3 on the new computer then I put Xubuntu over the 19.3 when I found that Icould not connect the wifi with the 19.3.I also have 19.3 on my old computer.

So now you have Xubuntu on the new computer that you have just inxi'd?
....and Mint 19.3 on your old computer?

Just checking as I'm a bit slow-witted!

Yes, as I said the only Linux that works on the new comp is Xubuntu, both the last outputs, inxi and iwlist, were from the new comp+Xubuntu.

Sorry again for all the confusion!

That's OK. 

The disk of your new computer has a single partition that occupies almost the whole drive, so I doubt that there are any Windows influences - and in any case that would be unlikely to affect the wifi and backlight, etc.  The very low wifi signal level does indicate a potential problem but you say Xubuntu does connect OK which is odd.
 
Have you tried a re-install of Mint19?  If you get the same result, then perhaps try Peppermint 10, also based on Ubuntu, for comparison.  https://peppermintos.com/
