As I suspected. Jim caught and corrected 1 of the original typo<br>
issues, tried it literally, but then soon determined that there was<br>
no "there there", as the originally presumptive also failed to match<br>
the target anyway, and hence no corresponding<br>
/etc/init.d/network at all.<br>

Ew, yuck, network-manager. Well, if you only deal with relatively simple<br>
networks and want an Ewey-GUI networky thingy that many distros install<br>
by default, ... then network-manager is your answer ... for certain<br>
definitions of "answer". On the other slight very possible plus side,<br>
it does also have a CLI interface ... a horrible non-standard<br>
abomination of an interface, but nevertheless probably pretty functional<br>
and reasonably well documented (Debian has nmcli(1), does your distro not?).<br>
(you can also leave the sucker installed, but not enabled - which is what<br>
I do most of the time ... if/when I ever come up with reasonable reason<br>
to mess around with network-manager- it's already all installed for me).<br>
<br>
Sometimes for troubleshooting, it may be more convenient, to at least<br>
temporarily disable Network Manager - your results may vary (typically<br>
by default, network manager tries to automagically do a lot of stuff,<br>
often changing dynamically ... that can get in the way of figuring out<br>
what the hell is actually going on, as the playing field tends to often<br>
be regularly changing (I'm presuming you didn't work in some highly isolated<br>
radio signals environment, where all but the desired Wi-Fi client, and access<br>
point, all their radio signals blocked well below the levels that any <br>
commodity<br>
Wi-Fi equipment would be able to use at all - and hopefully not even detect).<br>
<br>
There are other commands that might be useful - after the system reasonably<br>
sees the hardware and Wi-Fi device. In the meantime I think we're awaiting<br>
your updated reporting results.<br>

Are you *sure* it's Ubuntu 18.04?<br>
Ubuntu 18.04 is soon approaching a year old.<br>
Are you not to ... well, I'm too annoyed to click through<br>
Canonical's begware please give money to your favorite company<br>
Canonical screens ... oh, I don't know, like 18.04.1 (or .2 or .3 or .4)<br>
by now?<br>
What command did you run that tells you it's Ubuntu 18.04?<br>
And what was the output of that command?<br>
What about the architecture (might be moot ... or maybe not, depending<br>
upon the "spin"/"flavor", or whatever *buntu call it of *buntu)?<br>
Again, what command did you use and what did it show you?<br>
Some of these might be useful:<br>
$ lsb_release -d<br>
$ uname -m<br>
$ more /etc/*rel* /etc/*ver* 2>>/dev/null | cat<br>
<br>
And peeking a bit, even if you are, in fact, running Ubuntu 18.04,<br>
rather than 18.04.1, not too horrible, it's at least still supported<br>
thus far:<br>
<a href="https://wiki.ubuntu.com/Releases" rel="noreferrer" target="_blank">https://wiki.ubuntu.com/Releases</a><br>
But if you want to stay with the LTS track,<br>
you'd probably want to upgrade to 18.04.1 (security, bug fixes)<br>
<br>
What model of gizmo?<br>
Hmmm, gizmo, don't know that make,<br>
if that's the actual manufacturer's make labeling on it,<br>
I think we'd all be curious to see it.<br>
So, yes, make and model would be useful.<br>
Also, Linux and the related Wi-Fi bits don't care much about who's<br>
label/branding is slapped on the thing, but they do quite care about<br>
the chipsets, so while make/model can be useful,<br>
they chipset(s) seen is often both more informative and definitive.<br>
<br>
>>> using wifi until my wifi gizmo died, maybe<br>
>>> with a last electronic shriek. I've got<br>
Really? What manner of death? Wi-Fi hardware is generally quite<br>
quiet - generally silent, so a "shreik" sounds comparatively unprecedented.<br>
Was that before or after the funeral pyre, and did the attending confirm<br>
death before that, and were the proper hazardous materials and burn<br>
permits obtained in advance?<br>
<br>
And if the Wi-Fi hardware is in fact confirmed dead,<br>
what exactly are you trying establish Wi-Fi connectivity through? ...<br>
Specifically between the (presumed) Ubuntu 18.04 host and the<br>
Access Point (AP)?<br>
<br>
Have you taken a look at rfkill(8)?<br>
$ rfkill list wifi<br>
0: dell-wifi: Wireless LAN<br>
Soft blocked: no<br>
Hard blocked: yes<br>
2: phy0: Wireless LAN<br>
Soft blocked: no<br>
Hard blocked: yes<br>
$<br>
Sometimes turning it on helps, see the difference?:<br>
$ rfkill list wifi<br>
0: dell-wifi: Wireless LAN<br>
Soft blocked: no<br>
Hard blocked: no<br>
2: phy0: Wireless LAN<br>
Soft blocked: no<br>
Hard blocked: no<br>
$<br>
If you get it Hard (typically hardware switch) and Soft(ware)<br>
unblocked (blocked: no), you might be able to do something with it,<br>
and notably also rfkill might tell you quite concisely if it's recognizing<br>
any type of Wi-Fi hardware.<br>

Don't presume the bus or bus type of the Wi-Fi. Sure, PCI or the like is<br>
common, but that's not the only place these things show up.<br>
<br>
Caveat: viruses may cause snarkiness and other malfunctions, mostly a non-<br>
issue for Linux (at least reasonably cared for), the human(s),<br>
however ...<br>
<br>
HAL: Well, I don't think there is any question about it. It can only be<br>
attributable to human error. This sort of thing has cropped up before,<br>
and it has always been due to human error.<br>
