My wifes laptop recently went in to get the screen fixed and it came back not working.
nice that they don’t tell me exactly WHAT settings they have reset.
Because of their tinkering with things they had no need to tinker with as all they needed to do was replace the laptop lid & screen, I am now unable to connect wirelessly to the internet.
The laptop is an ASUS Notebook X541B running Kubuntu 16.04
What’s the output from
lsusb
and
lspci -vnn | grep -i net
and
sudo rfkill list
and
iwlist scan
as well as checking wireless isn’t disable by a hardware switch (or key combo), check it hasn’t been disabled in the BIOS.
BTW, if these guys changed some “incorrect” settings, do they understand Linux ? … I wouldn’t have expected PC World techs to.

PC World? Loose screws? Whatever next?
If it’s not something daft like wifi switched off or a matter of signing in to your network then personally I would take it back to PC crapworld and tell them to fix it, they had no right pissing about with the way you had it set up they were only asked to fix screen.

This is the result of me allowing wireless back on
iwlist scan

When it goes off, does running
sudo rfkill unblock all
bring wireless back ?
A precursor to that command ^^^ is
sudo rfkill list
No, but it stops trying to constantly connect and report no wireless connection.
Do you have more than one wireless network configured in network manager ?
No, the others you see are what the laptop is picking up from other houses, mine is the first one, SKYA6E85
I realise that, I just wondered if you also had 2 (or more) wireless profiles configured in networkmanager.
You might want to change your routers channel to say channel 3, 4, 8 or 9 because someone else close to you is also using channel 1
and check if that makes a difference.
Is 16.04 particularly problematic? Would an upgrade to 18.04 be better?

Since getting the laptop back there’s been quite a few updates and the wireless problem seems to have fixed itself!!!
Yep, great news, but sadly, the lptop has just packed in, it won’t power up with the mains power connected. So it looks like another trip to the dreadded PC World…
Or a second hand Dell ‘E’ Series
It was the power cable, more precisely, the bit that plugs into the laptiop, it’s not a very good fit, slightly loose.
So you don’t need a new PC ? … that’s great news
