G'day JeremyB

Finally home and booting with Ethernet connected have got on line and the output from your suggestion is hopefully attached. It's titled "wireless-info.tar.gz"
Hope this can shed some light of the problem of the disappearance of the WiFi connection.

Noted the Ethernet connection icon has disappeared from the bottom panel of Mate desktop.

Cheers jbh911

A few things there that are not default

/etc/network/interfaces has some things that may confuse the system

Code: Select all

sudo gedit /etc/network/interfaces

and make it be

Code: Select all

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

Save and exit program

Then

Code: Select all

sudo gedit /etc/resolv.conf

And add this for the first line

Code: Select all

nameserver 127.0.1.1

Save and exit program, reboot and see if it will connect

Hi JeremyB

1 /etc/network/interfaces --- was already as you requested!
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

2 Inserting nameserver 127.0.1.1 as the 1st line in /etc/resolve.conf saving and rebooting did not produce a WiFi connection.

3 A check of /etc/resolve.conf following the reboot was back to normal, ie the additional line of code was removed

4 Replaced the 1st line in /etc/resolve.conf with nameserver 127.0.1.1 saving and rebooting did not produce WiFi connection

5 A check of /etc/resolve.conf following the reboot was back to normal, ie with the original code. As it states in that file "not to change by hand as it will be overwritten.

Cheers

Code: Select all

sudo gedit /etc/NetworkManager/NetworkManager.conf

And under [ifupdown] change managed=false to managed=true
Save and exit then

Code: Select all

sudo service network-manager restart

[jbh911]

1 Successful change to NetworkManager.conf

2 ~ $ sudo service network-manager restart
network-manager stop/waiting
network-manager start/running, process 3293

Noted Ethernet icon on panel closed. [Ethernet network connection 'ifupdown (eth0) active]

Rebooted and Ethernet icon on panel OPEN

3 Rerun ~ $ sudo service network-manager restart
[sudo] password for johnb:
stop: Unknown instance:
network-manager start/running, process 2829

Ethernet icon on panel closed. [Ethernet network connection 'ifupdown (eth0) active]

Saturday 12:30 hrs Booted laptop - long NetworkManager delay with (eth0) connecting after a delay
ifupdown (eth0)
Disconnect
DSL connection 1 ....
VPN Connection
Re-booted laptop - and it booted without the NetworkManager delay. 1st boot withour NM delay since accidental dis-enable of WiFi. WiFi still not being recognised.

5 minutes later - cold booted - and it booted without the NetworkManager delay and straight into (eth0) & WiFi connections recognised. Connected to local WiFi How good is this Linux software!

However can't access forums.linuxmint.com/ times out! WiFi speed extremely low. Can load local small web pages only!
Is this a NetworkManager issue or something else?

[jbh911]

All sorted! Just had to reconfigure WiFi setting back to home setting.

Thanks a million, JeremyB much appreciated

Ooops I was a bit to quick with the Solved conclusion.

PM Sunday booted the laptop without the eth cable connected and 10 m away from the WiFi modem. Got Networking disabled, No WiFi detected or showing, no attempt to seach for WiFi.
Booted laptop within 1 m of the WiFi modem and same result.
When Eth cable connected there were 5 attempts with a Requesting an ethernet network address for `DSL connection 1' ......
No mention of WiFi with either L or R mouse on Eth icon on bottom panel.
A check of Network Setting revealed the Password type (security) had changed and the Network password had been deleted!
Replaced this data and the Edit connection shows
DSL
DSL connection 1 never used
Ethernet
ifupdown (eth0) now
WiFi
linksys 1 day ago
Plus all the USA WiFi sites - which I have now deleted.
Rebooted - and the NetworkManager configuration delay is back but the Ethernet network connection 'Ifupdown (eth0)' active after a short delay
No mention of WiFi with either L or R mouse on Eth icon on bottom panel.
Looks like this could be a long process sorting this issue out. Would doing an online update to LM 17.1 help?

[JeremyB]

I would try the Live version of LM17.1 Cinnamon and see if it isn't something specific to the Mate desktop

Hy i may have the same problem, but i'm not sure about.. so...

Not so long ago i installed: Linux mint 17.1 (cinnamon) on to my laptop(msi vr630)
Since 1week ago it worked correctly**, but now it can't see the network and does nothing when i try to turn on/off with the Wi-Fi button.
I didnt messed with the system so i dont have a clue about the reason... but i remember, this machine did (almost) the same, a few times, with windows7.
But there, the network troubleshooter fixed somehow (if i remember correctly, the problem was with: network adapter configuration)
- Maybe it's not just a Wi-Fi problem, cuz' the bluetooth do the same, and the moon sign (for sleep) lights constantly..

- No way in the bios menu to manipulate the Wi-Fi
- When i try ~sudo rfkill list - there's no result
- The ~iwconfig - says - no wireless extensions.

~ $ inxi -n
Network: Card-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller driver: r8168
IF: eth0 state: down mac: 00:24:21:68:81:cb
Card-2: Ralink RT5370 Wireless Adapter
IF: N/A state: N/A mac: N/A

**thus i think, the drivers should be ok.

Any Idea??

Hi JeremyB

Resolved the problem by doing a clean install of LM 17.1. I can disconnect and reconnect the WiFi without any problems.
Tanks for your help.
