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:

Code Select Expand

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:

Code Select Expand

uname -a

Hi Mark,
Is this ok,
[email protected] ~ $ 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

[chemicalfan]

Won't he have to recompile the drivers against the new kernel headers? Or have I misunderstood how that fits together (again)?

[Mark Greaves (PCNetSpec)]

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

@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

[donwatson]

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)

[donwatson]

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

[Mark Greaves (PCNetSpec)]

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:

Code Select Expand

nmcli nm status
copy the output to a text file.

Reboot so you can connect

post the output back here

[donwatson]

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

[email protected] ~ $ nmcli nm status
RUNNING         STATE           WIFI-HARDWARE   WIFI       WWAN-HARDWARE   WWAN     
running         disconnected    enabled         enabled    enabled         enabled

Hope this helps

If your connection is called "VM185937-2G", and the wireless device is "wlan0" does it reconnect it you run:

Code Select Expand

nmcli -p con up id "VM185937-2G" iface wlan0
