No Wifi Connection, Netbook Mini 10 [SOLVED]
« on: September 10, 2014, 08:49:56 am »
To PCNetSpec - I was following the instructions that you had offered up on this topic previously and they I still have nothing I realize that those instructions might change based on the results from the lshw.  I'm setting up the PeppermintOS on a Dell Netbook Mini 10 - great little system and I think this flavor of Linux is going to be awesome once I have all of these tweaks cleaned up.  I ran an lshw (below) and do NOT have any wireless signal in the tray.  I tried going into to manually setup the Wifi connection but to no avail.  Can you offer any insights?  Thanks in advance.

That output mentioned kernel 3.8 and "raring".. is this Peppermint 4 (as opposed to Peppermint 5) ?

Truthfully, its been a while since I did the initial load on this but I think that is correct.  When it goes to the login screen, I've got that wood-looking background with the peppermint logo - isn't that 4?

   ***Just saw this on my Chromium browser:  running on Peppermint 4 (31.0.1650.63-0ubuntu0.13.04.1~20131204.1)

Yeah, that's Peppermint 4

Problem is the drivers for the broadccom low power cards (lpphy) was installed differently in Ubuntu 13.04 (so therefore Peppermint 4), and Ubuntu have now removed the package repositories for 13.04 as it's no longer supported.

Peppermint 4 should be considered "end of life" and you should *really* consider installing Peppermint 5 in its place .. you will receive NO more updates (including security updates) as long as you stick with Peppermint 4 (and Peppermint 4 still has the ssh vulnerability).

That said, if you want to continue in Peppermint 4 we'll first need to get you hooked up with the "old-release" repositories so we can install the firmware-b43-lpphy-installer package  .. can you post the contents of the file that opens when you run this command:
Code: [Select]
gedit /etc/apt/sources.list

There's nothing really compelling that is causing me to stick with P4.  If I would be better served with P5, then, I'm in.  Is there any preference to doing a fully new install versus an upgrade.  I don't have anything on this box that can't be wiped.

And by the way, many, many thanks for the assistance with this and on behalf of all of the other Noobs that you help out there.  Your advice and the response time amaze me.  If there is a donations page that I should be aware of, please don't hesitate to point it out.  If it helps, I was just looking at the PeppermintOS Sticks for sale out there and was thinking of buying one for the upgrade (as well as a couple of stickers.)  Again, thanks.  DW

There is NO safe way to "upgrade" Peppermint 4 to Peppermint 5 .. it requires a fresh install.
(obviously that doesn't mean you can't copy off your user files and say web browser config directory before doing the fresh install)

The good news is that Peppermint 5 is based on an LTS release, so if you choose to stick with it, it should be "good to go" until 2019

Give me a shout if wireless still doesn't work in Peppermint 5 .. but connecting to your router with an ethernet cable and running:
Code: [Select]
sudo apt install b43-fwcutter firmware-b43-installer firmware-b43legacy-installer linux-firmware-nonfree
should fix it right up :)

Oh, and thanks for the kind words .. you're most welcome :)

Nice one!

I just corrupted the WiFi firmware in my Dell ATG D630 'road warrior' while installing the 'intel-microcode' & 'iucode-tool' packages. 

Never had a problem with that Intel microcode/tool before, but when I rebooted, my WiFi has missing -- no LED indicator -- nothing. 

Everything pointed to a firmware problem, so I used the command line (above) and the WiFi magically reappeared.  Not only that, but I would swear the connection is better now -- more solid -- judging by the signal strength indicator.

Thx

I've never heard of the 'intel-microcode' & 'iucode-tool'  packages .. gonna need to check what they are  :-\

Here's a pretty good description of 'intel-microcode' :

SOURCE:  http://dereenigne.org/debian/update-intel-cpu-microcode

Quote
You are probably familiar with the terms firmware and drivers in the context of computer hardware, and the endless updating that they require. Most people associate these drivers and firmware updates with peripheral equipment such as graphic cards and DVD drives. You might not however be aware that you can also update the firmware on your CPU (firmware is called microcode in CPU speak).

These microcode updates are normally bundled in with BIOS updates. Given the fact that BIOS updates are inherently risky, motherboard manufacturers are reluctant to issue BIOS updates for anything other than major bugs. This means your microcode can become quite dated. Both Intel and AMD realise this and release standalone microcode updates.

If you are running Debian or Ubuntu and Intel CPU (there is a pretty good chance you are), you can use the intel-microcode and microcode.ctl packages to update your microcode. This will download the latest microcode for your CPU and apply the update automatically on each boot. This process does not apply the update permanently, and is completely reversible.

And, 'iucode-tool' :

SOURCE:  https://gitorious.org/iucode-tool/pages/Home

Quote
iucode-tool is a system administration tool to manipulate Intel® X86 and X86-64 processor microcode update collections. It is tailored to help Linux distros do Intel microcode update release management.

iucode-tool cannot change either the microcode itself (the opaque data that is sent unmodified to the system processor to perform the microcode update) or the microcode update container (a documented wrapper with metadata about the microcode update). It lets one create new collections of microcode update containers, by selecting which microcode update containers should be copied unmodified from the microcode data files published by Intel.

It can also display the contents of microcode update collections, in order to help the Linux distro maintainer keep track of the microcode updates available for each Intel processor, for release management purposes.

This release management is necessary to avoid microcode patch level regressions when updating the stable or long-term-service releases of a Linux distro. Intel removes microcode updates for very old end-of-line processors from the public distribution. When a Linux distro blindly propagates such updates to their stable branches, they potentially regress the microcode for some of their users.

iucode-tool was initially written for internal use by the Debian GNU/Linux distro, however, it is maintained with clear separation between upstream code and Debian-specific details and packaging, so it is appropriate for use by any Linux distro.

I usually install these packages when I do a fresh install. It's one of the first things I do.

In my defense, I never planned to run the P5 Beta this long.  LoL.  I was going to haxor it, then do a fresh install of the final.  But, it's been running so good, I decided to let it be.

I decided to optimize my SSD today, and install 'intel-microcode',  'iucode-tool', and so forth, and so on.

I've never installed 'intel-microcode' this late in the process.  Plus, my Internet connection has been motorboating up n' down all day.  One, or the other, ate my WiFi firmware.

No big deal.  It just caused a little head scratching...   8)

Ahh .. you learn something every day eh ? .. I did not know that :)

On the whole I've never been a fan of firmware updates (or even BIOS updtaes) unless they address a specific problem I'm suffering.

They say it's code loaded at each boot, which although probably a safer option and would allay most of the reasons I normally steer clear, I'm going to *guess* that to work quickly enough the code must be loaded and stay resident in the CPU somewhere and that's likely to be where? .. Primary cache? .. wouldn't that slow down the CPU ?
(or maybe they have a special area of cache that's set aside for just this purpose)

As I said, if it addresses a particular problem I have I'd probably try it .. but I'm not one of those that updates their DVD drive firmware or BIOS just to have the latest version.

That said, it's nice to know it exists .. so cheers for that :) .. do they publicise what issues the latest microcode addresses anywhere ?
