Wi-Fi not working? It's time to consult the lovely people on those fine Linux forums

(2021/12/20)


Who, Me? Welcome to another edition of [1]Who, Me? in which a Register reader makes the impossible possible and actually gets Wi-Fi working on Linux.

To be fair to the Penguinistas choking on their mince pies, our tale is set more than 10 years ago, when making Wi-Fi work under Windows could be challenging, let alone on everyone's favourite open-source OS.

Our story comes from a reader we'll call "Erik" (for that was not his name) who was trying to pop a new version of Linux on his laptop. He was a big SUSE fan but distro-curious, also tinkering with Ubuntu at the time. Alas, exactly which distribution and version is lost to time, so for the purposes of this story we'll go with "Linux."

[2]

The install went well, but all the bells and whistles of Erik's laptop did not seem to be supported. Most importantly, the Wi-Fi. Naturally, he hit the forums in search of help.

[3]

[4]

"Searched for same model and same problem," he said, "and lo and behold, exactly the same case shows up!"

Great news! And even better, there were pages of comments after it, meaning that somewhere there was likely to be an answer rather than someone posting "x doesn't work" in 2002 and then in 2015 another agreeing.

[5]

"So, I started to do what the nice people in the forum suggested to the original poster," recalled Erik.

Comment after comment he followed, seeming to take the same path as the original poster. Everything the original poster experienced, so did Erik. Drivers were uninstalled and reinstalled. Tests were run. Configurations were tinkered with. Down through the suggestions Erik went, but, like the original poster, without success.

[6]Ooh, an update. Let's install it. What could possibly go wro-

[7]How to destroy expensive test kit: What does that button do?

[8]When civilisation ends, a Xenix box will be running a long-forgotten job somewhere

[9]A tiny typo in an automated email to thousands of customers turns out to be a big problem for legal

With Wi-Fi still out of action, he went to the next page and carried on down the thread. Right to the very last entry. Made by the original poster.

"Oh, my bad, turns out there is a button on the side of the laptop to turn the Wi-Fi on and off, and it was off!"

Erik had the same model of laptop. With the same switch. Which was in the same position. The software had been willing. The hardware had been weak. A single push of the button and Linux went wireless.

[10]

"This taught me several things," sighed Erik. "One of them is to first read the fine forum thread until the end."

"Nice" and "Fine" are rarely words to be associated with modern-day forums (except ours, of course). Then again, it is also too easy to blame Linux for hardware incompatibilities when the problem has less to do with the OS and more to do with the person in the chair.

"first read the fine forum thread until the end"

Pascal Monett

Actually, the first thing to do would have been to read the manual of the machine.

Right, I'm off now. Mine's the one with the manual I forgot to read last year.

Re: "first read the fine forum thread until the end"

Chris G

You do know that no self respecting chap will read an operating manual until after the kit has failed to work or is irretrieveably broken?

Re: "first read the fine forum thread until the end"

Antonius_Prime

As Sir PTerry himself once wrote:

"One of the universal rules of happiness is: always be wary of any helpful item that weighs less than its operating manual."

(I think from Jingo, but I'm open to correction...)

Re: "first read the fine forum thread until the end"

pavel.petrman

This reminds me, tnagentially, of a recent small talk I had with an elderly gentlemanin the doctor's waiting room. We talked about lithium batteries and how they are prone to catch fire when physically abused beyond their design limits, like throwing a smartphone on a concrete pavement from a window on the 8th floor. Or trying to force charge them when outside their designed temperature envelope. The gentleman, exasperated, exclaimed, but why nobody tells us? This is the first time I hear about this! Sir, was my answer, watch your grand children closely next time they unpack the newest electronic gadget you bought them, and marvel at the now inborn muscle memory of throwing the several booklets, chock full with warning and hazard information, nicely into the paper recycling bin, like a good child they surely are.

Re: Doctors waiting room?????

Anonymous Coward

What are these things?

didn't they go extinct sometime in early 2020? When it was deemed that doctors were too important to actually see people in person...

Nowadays, getting to see even a nurse in person (for a blood test) requires membership of the magic circle inner link at least around this part of the world (Surrey/Hants border).

Everything is done online or by phone or if a real examination is required, you are sent to A&E where real physicians still exist.

Actually, the first thing to do would have been to read the manual of the machine.

I disagree. This may get me some downvotes but imho:

RTFM is no longer a thing , at least not the first thing.

My elderly father had a habit of printing the manual out for ,say, a new smartphone .

He'd then complain 500 pages of A4 was too much to read and none of it was about the bit he wanted to know about etc .

Even getting the manual in pdf which might have "linked" table of contents or whatever , and a ctrl-F function is not my first goto.

The correct thing to do , like in the article , is google it and find a discussion about the same issue.

there are caveats , and tips tricks and a knack to learn obvs , but this is the easiest path.

A really good tip is go straight to the one with the URL stackexchange , and then remember to go to the "accepted answer" and not try to emulate the first post , which is "how not to do it" , as described by the OP.

Prst. V.Jeltz

crikey , I'd forgotton about those buttons .

Totally didnt see that coming . Thrown by the Linux i guess.

Not to brag but back then I would have .

I remember it being on my mental checklist of things to ask users , right after , "is there a powercut there?"

And when it became clear that users were incapable of establishing where their wifi switch was , let alone if it was on or off I collected a series of photos of the models we were using with big red lines , circles and arrows indicating THIS! HERE ! should be in THIS position.

Doctor Syntax

Been there, done that. 10 years ago there'd probably have been a WiFi indicator LED somewhere. There's little chance of that these days.

MiguelC

Same here, after exhausting SW solutions I went all the way and unplugged and re-plugged the wi-fi module on my circa 2005 HP laptop believing there might be an HW problem. Only to discover the wi-fi on/off switch when screwing the backplate in again

Doctor Syntax

You didn't check the Access Point first?

That's not entirely a joke because I have one that sometimes goes into a sulk and has to be rebooted.

oh...

lansalot

Monitor was broken the other day - not powering on. Re-plugged the HDMI, wiggled the USB-C adapter, the whole bit.

I'd forgotten to turn the plug on at the wall. Of course, being a laptop, that fired up instantly off the battery, and thus I was led up the "well, obviously I've plugged it in" path. Wasted a good 10 mins before my flakey battery informed me that power was running low....

Been doing IT professionally since 1987, fyi.

Re: oh...

Wally Dug

Nope, that exact same thing didn't happen to me a couple of months ago, no siree. Honest.

Sam not the Viking

Or the plug that appears to be connected and switched on but in fact, is not fully located into the socket. And leads have two ends......

Ditto that

Andy Non

got the T shirt. A family member presented me with an old laptop he wanted me to install Linux on. No problem I foolishly said. I'd recently updated the Mrs Windows 10 laptop to the latest version of Mint so had an installation stick ready to use. It just wouldn't have it though. Kept failing to install with an unreadable error message flashing past the screen lasting a millisecond. I turned the laptop over and noticed it had a sticker for Windows XP. Ah! the penny dropped, it was so old it needed the 32 bit version. Dug a 32 bit version of Mint out of the archives and that installed great, except no WiFi. Connected the Ethernet cable and got it fully up to date with all the patches but still the WiFi wouldn't work. Tried a plug in USB WiFi adaptor, nope didn't work. Eventually after much gnashing of teeth, I waded through the BIOS settings and noticed one to "Disable WiFi" which was ticked. Bugger. Turned the setting off and the WiFi worked. It never occurred to me that there would be such a setting.

Similar problem with a moped

TWB

Many years ago I had a Honda Express moped for getting around as we lived a little bit away from places I wanted to go.

One morning I was going to scoot to college (6th form - 11 miles) and it would not start. I changed the spark plug, checked the fuel was on and all the things I knew but still no joy. For several days it remained like this and my normal helper (Dad) was not speaking to me because we had fallen out about something else.

One day in a calmer frame of mind I re-checked the little fuel on/off/reserve tap and remembered that when the fuel was low, you could switch it to 'Reserve' which allowed the last pint or so to be used - hey presto.....

I decided not to explain to my Dad immediately as we were, by then, exchanging some words.

Re: Similar problem with a moped

Graham Newton

I had an Honda NSR125 which I had to sell last year after 20 years. One morning it wouldn't start, it was still under warranty so I got the AA out. Who also couldn't start it. I was only when the bike had been partially dismantled that the AA man noticed that I had accidentally pressed the emergency kill switch.

stungebag

Yes. tell me about it. I was network manager in a school that owned 600 HP laptops and the most common problem brought to us could be easilly diagnosed by observing whether the little blue light by the little sliding switch was illuminated or not.

jollyboyspecial

I have lot count of the number of times I've fixed laptop wifi issues by simply switching on the wifi.

Sometimes it's been a switch, sometimes a button and sometimes a function key combination. You always get the same sort of response from the end user, along the lines of "I never switched it off" or "it must have switched itself off" or my particular favourite "I've tried that several times" all of which are evidence of the end user trying to avoid either embarrassment or a call out charge.

And the silly thing is...

TWB

..that many of us here like proper hardware switches for such things;- camera covers, microphone cuts etc.

I suppose ideally the OS should be able detect the switch position and report back to the user* but have no "ability" to change it.

*Ideally something like "The wi-fi switch on the outside of your machine is in the off position - please move it to the on position to enable wi-fi" - rather than "system error 3456HZQQF227 - please contact your administrator"

No intention to blaspheme, but …

when it is a button, then it can be turned on and off by software as well. ;-)
