odd network behaviour (solved)

[andrew110]

I have an HP 8440P that I acquired used recently and have been setting it up as a dual-boot system so someone unfamiliar with Linux can use it. The Linux distro is the 64 bit version of Mint 17 MATE. Initial install was from a live USB drive, and the installion went without any problems. The computer was connected vias Ethernet to get all updates, and initially I ran it using wired connections while I got everything sorted out. Finally came to the point where I wanted to activate wireless connectivity, and that's when things got......strange. Used the Network option in Menu, opened up wireless option, and entered SSID, security option and network password. Closed out, disconnected the Ethernet cable, and......nothing. Double checked SSID and and reentered password, same response. Connected Ethernet cable and 'idiot light' on lower right of screen stayed in the "No conenction" indication. Restarted computer in hopes that this would put changes into effect. During boot-up, Mint insisted that I had no network connectivity at all, then after it let me log in, I pinged both the local gateway and a remote site (Google) and got positive results. Opened a browser session and went to several sites without problem, yet 'idiot light' still insists I have no connection to a network. WIreless, when tried, still refuses to open, queried via command line and was told that the wireless adaptor was working, but that it had a 169.x.x.x network address (yes, I did enable DHCP when setting up the wireless option).
Shut computer off completely, restarted....and nothing's changed.
Did a search here using both the laptop model and wireless problems in general, and found nothing even close.
Used the suggested command to query network connections and got this:

The truly frustrating thing about this is the fact that even the wired connection has been effected. And yes, the wireless router is configured to handle DHCP duties, and I use other devices with it without any problems. So anyone have any idea what I managed to screw up?

Hello and welcome to this forum!!

I had a similar problem with an HP Elitebook 8530p.
Turned out the wifi enabler only worked well under Windows.
So after enabling it from within Windows7 it also worked under Linux.
Probably HP didn't tell the Linux community how to solve this or no one ever tried solving this.

thanks for being the first reply. unfortunately, I have no problems connecting to my wireless network from Windows....but Linux still refuses to make a wireless connection, and the wired side is still not behaving properly. damn, I *hate* being the first person to find a problem!

Are the correct drivers loaded for wifi

Code: Select all

lsmod -nnk | grep -iA2 net

The broadcast ip for the wired connection doesn't appear to be correct. With you current ip it should be 192.168.1.255

my version of lsmod doesn't allow command switches, insists on having the program run 'bare', and grepping the results using the sorting parameters you give yields nothing. here's what I get when I run lsmod:

not too concise, I know, but just from looking, I can't see anything beyond "rfcomm" that might be used for for 802.11x wireless. sorry, and thanks for the help.

What do you see after running this command

Code: Select all

cat /etc/default/avahi-daemon

[andrew110]

What do you see after running this command

Code: Select all

cat /etc/default/avahi-daemon

here's what coes back:

# 1 = Try to detect unicast dns servers that serve .local and disable avahi in
# that case, 0 = Don't try to detect .local unicast dns servers, can cause
# troubles on misconfigured networks
AVAHI_DAEMON_DETECT_LOCAL=1

from which I can deduce that the machine is looking to the local router to do DNS services, which it should be doing. what I find strange in all of this is the way wired networking behaviour changed. before I tried to set up the wireless connection, the laptop conencted to the wired Ethernet port without a hitch. now, it sets there after starting Mint, waiting for 'configuration' from the network like it was expecting to find configuration information coming in off a server instead of just an IP address.why it suddenly expects this information is nearly as much of a puzzle to me as why it can't seem to find the wireless network. as the original title of the thread says, odd network behaviour indeed.

Lets see if the wifi script will find some clues, and install pastebin to upload the results

sudo apt-get install pastebinit

Code: Select all

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

If you choose y when asked about uploading to pastebin it will give you a URL that can be copied and pasted into a post

a quick look at the results shows the following information for the wireless system:

now, the first question I can think to ask is: is iwiwifi the proper driver to use with my 802.11 interface?

iwlwifi is the only driver for most of the intel chipsets and it either loads with iwldvm or iwlmvm depending on firmware version

well, in that case, I guess I'm back to the original problem: why isn't the wireless network connecting, and what did I do to change the networking parameters?

########## wireless info END ############
I noticed something else: when I checked the wireless setting in the 'network' function, I found that for some reason it hadn't saved the wireless network password. re-entered the information, saved it (which I was sure I did earlier) and disconnected the ethernet connectuions to try to establish a wirelss connection. no joy, and when I moved to the network icon at the bottom right, it showed both wired and wireless connections were not being "managed". that tells me why it pitches a fit during start up, but as to *why* it's not managing either of the connections.........now that's a good question.

You must have added quite a bit to your interfaces file, usually it only contains

Code: Select all

auto lo
iface lo inet loopback

It might be worth the time to delete or comment out the lines that begin with wpa

Pastebin just uploads to a webpage and I think the uploads are deleted in 30 days where dropbox uploads stay until deleted
I prefer pastebin to pasting large pastes to the forum because I use tapatalk on my phone and it turns things into smilies even when code tags are used

actually, I haven't added anything, this is the result of running a fairly stock installation of the 64-bit version of MATE. as I said, the only thing I've done to this install is to try using the network option to set up the wireless network. not being sure I won't have to reinstall, I haven't done or added much of anything. I'd also wonder how commenting out all lines dealing with WPA is going to affect my ability to get a WPA-based network connection up-and-running. I'd be willing to try, I just wonder how it's going to help get things cleared up.

[JeremyB]

We could try just commenting the lines out by adding a # in front so it is easy to change back if it is really needed

Code: Select all

sudo gedit /etc/network/interfaces

and make it look like this

Code: Select all

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

#iface wlan0 inet dhcp
#wpa-driver wext
#wpa-key-mgmt WPA-PSK
#wpa-proto WPA
#wpa-ssid theexperimentw1

#auto wlan0

#iface eth0 inet dhcp

#auto eth0

save and exit program
reboot

This should work on your network as I have 4 linux laptops on my network and they are all this way. Hopefully these changes result in

Code: Select all

nm-tool

showing wlan0 as State: managed

[andrew110]

made the changes, and the wired network is now behaving as it was before this little adventure. OTOH, when queried with network management tool, I got:

- Device: wlan0 ----------------------------------------------------------------
Type: 802.11 WiFi
Driver: iwlwifi
State: disconnected
Default: no
HW Address: 18:3D:A2:6E:9F:70

and when I unplug the Ethernet cable, the wireless connection does not establish. so I guess I'm back to figuring out why I can't get wireless to connect. time to go through the man page for iwconfig?

You should be able to connect through Preferences- Network Connections, and you may have tried before from Administration- Network

GUI looks like https://www.dropbox.com/s/n2vq95l1reoxg ... s.png?dl=0

With ethernet cable unplugged you might even be able to click on the taskbar/notification bar networking icon to see available connections

yes, I originally went in through the Administration sub-menu, and got into the situation that led me to start this thread. just set up the wireless network through the Preferences option....and everything worked without a hitch. now, if someone can tell me why this option worked, and the other screwed everything up, I'd be happy.
thanks for the help, I appreciate it.

............and now, how do I mark this thread as "Solved"?
