wifi dropped /on after CLI query,mintWifi.py file problem? [solved]

Hope you folks don’t mind me repeating this here, having a struggle to get an answer on the LM forums, seems quiet the last couple of days and I’d like to find out what’s causing this:

I was setting up SSH to network last night on the laptop, (done it before but the upstairs PC is new, so wasn’t set up on that one) and it seemed to go fine. Today wireless wouldn’t work, my wireless network kept coming up in network manager as a hotspot promting me to ‘turn it off to connect to a wireless network’, didn’t work, tried ‘forgetting’ the network, it wouldn’t. All the time it was telling me I was connected. . . … . looked at the top of the wireless forum, tried this - and it’s now connected??? What hapened please, I don’t know as yet if the connection will last but if there’s anything I need to do I’d like to know?

Also adding in my mintWifi.py file contents in the hope someone can have a look and see the glaring omission that I can’t, this is from the laptop sitting there now in a - not connected - state, I assume if I run the command above again I will connect again but that’s not solving my problem or telling me why.

Thanks in advance…

Which command did you run to get it working ?

Hi mark, I’ve just been searching around and trying all sorts restarting the network manager and everything else I can find, the python file on my toshiba laptop appears to be identical to the T61 when I’ve checked, the only way to get it to connect is to apply the command

sudo /usr/lib/linuxmint/mintWifi/mintWifi.py

Trouble is it doesn’t keep after a restart, no idea why this has happened or whether it was just a coincidence I was networking it the other day but it all seemed fine at the time.

That’s just a diagnostic tool which prints output to commonly use diagnostic commands in one go … so quite how that’s bringing your network up is beyond me.

Can you reboot, then whilst wifi won’t connect, can you bung the output from these commands into a text file:

ping -c 5 173.194.34.128

and

ping -c 5 google.com

and

sudo lshw -C network

and

rfkill list

and

sudo iwlist scanning

and

ifconfig

and

iwconfig

then do whatever you need to do to reconnect, and post the output here.

Hello Mark,

my outputs as requested:

Just for the record, my networks name is "unsecured wireless network" ;) I have inserted some x's here and there to avoid broadcasting my info to the world :)

Can you do whatever you need to do to have an active connection, then post the output from:

ifconfig

and

iwconfig

So we can compare the working output with the non working output.


Also, whilst the connection is broken, are you able to ping the routers IP address
ping -c 5

example
ping -c 5 192.168.0.1

Here’s the output:

Thank you

Packet loss whilst pinging the router is very worrying - are you a long way from it?

What is your routers IP address ?

You seem to have 2 access points on the same channel (11) with similar signal strengths:

Cell 01 - Address: 20:E5:2A:FC:FD:C4 Channel:[b]11[/b] Frequency:2.462 GHz (Channel 11) Quality=25/70 Signal level=-85 dBm Encryption key:on ESSID:"unsecured-wireless-network"
and
Cell 04 - Address: C0:3F:0E:BF:3E:B1 Channel:[b]11[/b] Frequency:2.462 GHz (Channel 11) Quality=32/70 Signal level=-78 dBm Encryption key:on ESSID:"virginmedia3481569"

Try changing yours to a different channell and try again.

The laptop’s in the front room of the house, the router’s at the back of the house upstairs, it’s not exactly a sprawling mansion, just a semi detached :wink:
there’s maybe 30/40 feet distance in a straight line, but a couple of walls ceilings to bear in mind… it’s always been about 50-odd % reading on network manager, my toshiba laptops always about 50–60%, if I move into the kitchen below the router, signal gets better(nearer), as it would, never looked for packet loss before so I don’t know if it was always there or not. . . . router address is bog standard 192.168.0.1

I’ve changed the channel to No6, it still didn’t connect when I took the laptop down and booted up…

I don’t know if this will help but thought it might be an idea to include it FWIW…

This is what I can see when connected, it’s gone from being a normal connection to hotspot,

http://i.imgur.com/BGNrZHk.png?1

It then changes to wireless, and shows i’m connected, only I’m not !

http://i.imgur.com/vk3Rlm8.png?1

If I click on the black arrow to get to the other setings, it then tells me wireless is out of range and I can’t get any joy clicking ‘settings’ at the bottom as it does not respond, I can click and the button depresses as normal, but nothing happens. . . . .

http://i.imgur.com/EN5VOfh.png?1

Hope this helps…

OK, for some strange reason your wireless IP address is being set to

10.42.0.1

Which is clearly wrong

Have you given the wireless connection a static IP address for some reason … or is it getting its IP via the routers DHCP server ?

Have you tried simply restarting thee router (unplug, wait 10 seconds and replug) ?

Hello Mark, I haven’t tried a reset on the router yet, I’ll do that shortly - I did think it odd myself about my IP and the only thing I attempted recently was installing ssh and connecting/browsing my home network - I had it successfully set up on my LM15 laptop/LM13 desktop, then reinstalled 16 on the laptop, bought a new desktop and put LM16 on that too and only did exactly the same, i.e install ssh on both, the one and only thing I noticed was the different IP it was coming up with but I didn’t see that as something that could have affected my connectivity . . . . . . I’ll report back after a couple of minutes restart of the router . . . . .

Full restart but still no cigar . . . . . ??? I even went through both machines making sure they only had the openssh-server installed as I’d mistakenly installed some other packages a bit back so to count them out for interfering I’ve got rid so both machines are the same. My IP has changed though . . . . . some joy at least, it now reads 86.5.159.114

That IP address on your router is the public one (WAN)
What you need to find out is the private address off the router (LAN)
This could be in the range:
10.0.0.0 through 10.255.255.255
192.168.0.0 through 192.168.255.255

Are you using Virgin NotSo-Superhub by any chance?

Is your wireless network connection set to -

Method: Automatic (DHCP)

for IPv4

and

Method: Ignore

for IPv6

?

Hi again, yes it’s a virgin superhub, logging into it tells me this much:

LAN IP Address 192.168.0.1
WAN IP Address 86.5.xxx.xxx

And the problem now, which is why i posted those screen cap’s, was to illustrate that I can’t get to the settings now as my network manager’s telling me I’m a hotspot on the laptop, so I have to turn that off to enable wireless, when I do that, it them says wireless out of range, even 4 feet away, and the ‘settings’ button to get into the IP4V/6 settings doesn’t let me in any more . . . . . .

I’m getting the feeling I need to reinstall network manager?? Is this worth a shot, as I’ve mentioned prior to this, I have networked, I’ve took the laptop out and used my mobile as a hotspot through it, but to the best of my knowledge I didn’t ‘break’ anything 'cos it’s all worked . . . . . up to now . . . . .

Edit: FWIW- don’t know if this helps but on my toshiba laptop running mint 16 MATE IPv4 is automatic DHCP and automatic on IPv6
