Hi Mark,
I am having a bit of bother lately getting the WiFi to connect (again).
The icon on the screen shows 100% connectivity, but when I try to log on to a site the screen says it can't connect.
I tried on the Windows machine and everything is ok. When I come back to my Linux machine it is all working now.
I have printed off the instructions I received in an earlier thread and will follow them when this occurs again.
Hope you can understand what I am saying. I will return. ;)
take care
Don W

So what you're saying is:-
Linux is randomly dropping the wireless connection to the router ?
or
It doesn't drop the connection to the router .. but for a while Linux is unable to access the WEB even though networkmanager says the connection to the router is solid ?
Next time it happens, can you check if you're able to ping the IP address of your router, and ping Google by IP address and hostname
ping -c 5 <ip.address.of.router>
eg.
ping -c 5 192.168.0.1
and

Hi Mark,
I have been at this all morning and am now about to give up with frustration. :'(
I have tried the suggestion to ping
ping -c 5 216.58.210.35
and I get 'Network is unreachable'
and when I try
ping -c 5 google.co.uk
I get 'unknown host google.co.uk'

The ping of your routers local IP was probably the most important one .. can you do that next time.
Do you know your routers local IP address ?

I have rebooted the Linux machine and have connected with the router via cable. :D

Hi Mark,
I am just back and on the computer and the internet is working on the WiFi. ??
This is weird.

Don there's no point in running the ping command whilst connected with an ethernet cable .. that will tell me nothing about the wireless connection.
and
I need you (when wireless isn't working, and without an ethernet connection)) to attempt to ping YOUR ROUTERS IP address, NOT 216.58.210.35
Do you know your routers IP address ? <-- please answer this question
If you're not sure of your routers IP address, whilst wireless is working please post the output from:

Spot on :)
Next time the wireless drops out, can you (without connecting an ethernet cable) run the following commands and copy their output to a text file
and
and
and
and
and
once you've got the output saved in a text file .. connect to the router with an ethernet cable and post the output back here.
Would be a good idea to copy the above commands to a text file on your desktop whilst networking is still working .. so you have them ready to run the next time wireless drops out ;)

Hi Mark,
The connection dropped this evening so I ran the commands you suggested.
I have copied and pasted to a text file can I paste it here ?
take care

Hi Mark,
How can I insert the text I copied to the Text Editor.
I can click on 'Copy' and when I click here the options to 'Paste' are greyed out.

I take it you highlighted all the text in the text editor .. then clicked "Copy" whilst it was highlighted ?
You *should* be able to "Paste" here .. when "Paste" is greyed out it normally means the clipboard is empty.
Try installing a clipboard manager such as clipit
then run clipit from the menu (or reboot) to load it.
IIRC before having a clipboard manager you need to keep both applications open (gedit and the browser) to be able to copy/paste between them.

OK try this
(disables both firmware link power saving and software link power saving)
Open a terminal and run:
when a BLANK file opens, add a single line that reads:-
SAVE the file and exit gedit.
Now REBOOT to load the changes.

Hi Mark,
I have carried out the above instructions and rebooted.
Everything seems ok, will I give it a couple of days before marking solved ?

Hi Mark,
I found the page in the advanced setup.
It gives a list of pages from 1st basic page through 1st guest page,
The basic page has the 'Enabled' box ticked but there are no boxes ticked on the 'Guest' pages.

That's better, it's only showing up once now....
On this page in your router:
http://setuprouter.com/router/virgin-media/netgear-vmdg485/wifi-setup-34039-large.htm (http://setuprouter.com/router/virgin-media/netgear-vmdg485/wifi-setup-34039-large.htm)
what is the "security mode" set to ?
WPA auto or WPA-PSK(TKIP)
and what happens if you set it to WPA2-PSK(AES) .. be aware you may need to reboot any PC's that connect wirelessly to pick up the change.
and remember, if you can't access the router via wireless at all .. you can always use an ethernet cable to change the setting back.

Hi Mark,
The setting is WPA Auto
When I switched on this morning I got an indication that my wireless connection was @ 96% (it is down to 88% at the moment), I usually only get a signal strength of around 48% to 56% does this affect anything ?.
The gas board installed a new central heating unit recently and it is connected wirelessly. Will changing the settings to WPA2-PSK(AES) upset the settings for the heating ?

Shouldn't do, WPA2 is the standard now (WPA shouldn't really be used, as it's no longer safe - the encryption has been cracked)

Thanks chemicalfan,
I will do as Mark advised and see what happens. ;)
I'm back with the good news that it all seems to be working ok.
The wireless control for the heating is lit and is communicating ok.
The computer is obviously working ;) and the power bars for the connection show 88%.
So all in all I am a happy bunny :D
I will mark as solved and will open this thread again if it starts to play up if that is ok ?
take care

As long as you keep the wireless password the same it *should* be fine .. is there any way in the router settings that you can see what devices are connected ? (there usually is, but the VM interface is a bit dumbed down)
As chemicalfan suggests, WPA2 is the standard now .. i'd be surprised if your central heating wasn't capable of it
BTW, wirelesss central heating ?? .. why, are you able to control it wirelessly or sommat ?

Hi Mark,
Our posts crossed. ;)
The installer wanted to install the control on my mobile phone. This was so I could phone the controller and put the heating on before I arrived home ?
I can switch off/on with the computer and I can control timing and temperature with the computer but it is all a bit of a gimmick.
It is in fact a bit of a pain as it only works twice a day and you have to press buttons on the controller to set it on/off when you want it outside thes times.

Just to check you're now on WPA2, can you post the output from:
again.
I don't know if WPA2 will make your connection more stable .. we'll have to wait and see :)
Code Select
sudo iwlist scanagain.

OK as long as your routers SSID is VM185937-2G then you're definitely now on WPA2
But
Every time I ask you for the scan output your router has switched to a different wireless channel .. this time channel 11 which is the same channel as the other 2 routers around you are using.
I can only assume your router is set to automatically select a wireless channel .. and it's not doing a very good job.
If I were you I'd set your router to always use channel 8 or maybe 3 .. I haven't seen any of the routers around yo use either of those channels (they seem to favour 1, 6, and 11 .. so 3 or 8 give you some separation).
Once you've done that .. post tthe output from:
again

Hi Mark,
The same problem has occured again :'(
I switched the computer on (twice) and didn't get an internet connection.
I tried the old Samsung with the IntelAtom and it was ok. I opened this thread and got down to post 9 where it says to
ping -c 5 192.168.0.1
I switched on the offending computer and I have an Internet connection ?
I am getting fed up here. Everything is ok now. Is there anything I can do ?

Do you want to try updating to the 3.16 kernel series and see if that makes a difference ?
if so, can you confirm this is Peppermint 5 / Ubuntu 14.04 ?
