Hi Mark,
I am having problems ( again ) with my internet connection.
Would it be possible to upgrade to the 3.16 kernel series ?
I am running Peppermint 5

Yes, open a terminal and run:
sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic
when that’s finished, REBOOT.
Then post the output from:
uname -a
Hi Mark,
Is this ok,
don@ldwatson ~ $ uname -a
Linux ldwatson 3.16.0-34-generic #47~14.04.1-Ubuntu SMP Fri Apr 10 17:49:16 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Yup, let’s hope that helps with your wireless problem 
Won’t he have to recompile the drivers against the new kernel headers? Or have I misunderstood how that fits together (again)?
Did donwatson compile any drivers in the first place ? … I thought he was just using the ones provided by the kernel, in which case they’ll now be provided by the 3.16 kernel
Mark,
This is the third time I have posted this, hope it works this time.
Everything is looking ok at the moment but I will leave it until Monday before marking solved.
One point I have to ask is, at the moment I switch the computer on and off about 6 times a day, would I be better to switch on in the morning and off at night ?
Or indeed can I leave the computer permanently on ?
Your thoughts please.
take care
Don W
@Mark - I can’t remember, there’s so many posts about wireless adaptors, most seem to end up compiliing drivers! Considering the issues Don has had, I guessed it might have been suggested at some point. Anyway, seems like he didn’t from his follow up post
@Don - There’s nothing wrong with leaving it on apart from the waste of power. You can always set it to suspend instead of turning it out - it’ll still be on, but in a very-low power “sleep” state. If suspend doesn’t work (can be flaky), I’d do the morning-night suggestion
Thanks chemicalfan
This is a tough one to answer, different people have different opinions, it also depends on your priorities … certainly continued power cycling of electronics can cause them to fail sooner (keep heating/cooling something is akin to bending a piece of metal backwards and forwards) … but components with moving parts such as hard drives MAY last longer the less wear they get.
Personally I go with the always on option for desktops (except where noise may be a consideration such as in the living room) and my NAS … laptops on in the morning/off at night.
As I said other people will likely have differing opinions about the “always on”, but I think most people would say if you switch your PC on /off 6 times a day, you’d probably be better off just powering on in the morning, and off at night (unless of course power usage is the main consideration, say on a laptop that’s on battery)
Thanks for the advice chaps
I removed the battery at the beginning of the week as I only use the laptop at home.
If I sit in the garden I can use the power from the shed, it just means switching off before going outside, or refitting the battery.
@chemicalfan, I will go with the on in the morning and off at night option.
@ Mark, I remember reading somewhere about the chips becoming loose due to to heating/cooling, it was a long time ago.
I think that was what prompted the lock on the socket ? I dunno 
I will wait until Monday before marking this solved, when I will have another problem to set you ???

Hi Mark,
The internet connection has dropped out again. 
I checked emails etc this morning and all was ok.
I left the computer running while I did some work, after tea I woke the computer up and signed in, and, lo and behold no internet connection.
What’s next Mark ?
take care
Don W
So this is purely a resume from suspend issue ?
it’s no longer dropping out prior to suspending ?
next time it suspends and doesn’t reconnect after resume … whilst it’s NOT connecting, please run:
nmcli nm status
copy the output to a text file.
Reboot so you can connect
post the output back here
Thanks Mark,
When I finished my tea I came back to the computer, moved the mouse and signed in.
I saw that it hadn’t connected and the icon whizzed around a few times but it is still disconnected.
I will go back to the Linux machine and carry out the above request.
take care
Don W
I have ran the command, saved it and shutdown the computer.
I re started computer and I am connected to internet.
This is what I got from the command
don@ldwatson ~ $ nmcli nm status
RUNNING STATE WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN
running disconnected enabled enabled enabled enabled
don@ldwatson ~ $
Hope this helps
If your connection is called “VM185937-2G”, and the wireless device is “wlan0” does it reconnect it you run:
nmcli -p con up id "VM185937-2G" iface wlan0
?
Hi Mark,
My connection is “VM185937-2G”.
I don’t know the device, can I check it somewhere ?
I will need to wait until the problem strikes again to try that command.
The computer started ok this morning, I logged in and there was an Internet connection.
I have a bit of work to do today so I will let the computer go to sleep until I get back.
run:
ifconfig
you’ll see output similar to
mark@AA1-Blue ~ $ ifconfig eth0 Link encap:Ethernet HWaddr 00:1e:68:d5:92:04 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)lo Link encap:Local Loopback

Or you could run:
nmcli dev status
which will list the devices and their current status
nmcli dev status DEVICE TYPE STATE [b]wlan0[/b] 802-11-wireless connected eth0 802-3-ethernet unavailable
Mark,
I have switched on and there is no connection.
I ran the nmcli -p con up id “VM185937-2G” iface wlan0 command and it says
connecting (configuring) and then it says
disconnected then it says
Error: Timeout 90 sec. expired and puts me back to the prompt.
I ran ifconfig and it says wlan0
I also ran nmcli dev status and it returns
DEVICE TYPE STATUS
eth0 802-3-ethernet unavailable
wlan0 802-11-wireless disconnected
Last night I was on t’internet playing Backgammon and twice the programme hung and said I had lost the server.
Over the past couple of weeks I have had this problem a few times and wonder if it is connected.
The little signal level thingy was sitting was showing it still had a signal so I never bothered.
Mark,
I have shutdown the computer before having a shower and now I’m back and logged in and everything is working fine.
When the internet connection came on it showed 100%, this has now dropped to 52% ?
We’re quickly approaching the point where I say “get a USB wireless adapter”.
Have we tried disabling IPv6 and giving your wireless connection a static IP ?
Have you got a USB wireless adapter you could test it with … just to be sure it is actually the wireless card ?
