HP Compaq 6710 - Strange network problems

Hi gurus, I am experiencing strange networks problems. I am trying to teather internet from HTC Desire S with Android. Basicly I followed those instructions: https://wiki.archlinux.org/index.php...ring#Procedure

1.) Enable USB Debugging - Phone: Settings --> Applications --> Development --> USB debugging
2.) Disconnect computer from any wireless or wired networks
3.) Enable the tethering option from phone - Phone: Settings --> Wireless & Networks --> Internet tethering (or Tethering & portable hotspot, for more recent versions)

This worked as epxected first time I have tried it. But when I executed same sets of commands second time it did not worked (usb0 interface did not goes up and thus is not capable to obtain IP address), no system changes was done.


Code:
[root@HP-PC ~]# ifconfig usb0
usb0      Link encap:Ethernet  HWaddr 0B:16:21:2C:37:42  
          BROADCAST MULTICAST  MTU:1500  Metric:1

          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

[root@HP-PC ~]# ifconfig usb0 up
SIOCSIFFLAGS: Cannot assign requested address
In the past I posted problem which enabling wlan0 interface which still preserves http://www.linuxquestions.org/questi...bg-4175429962/ today while I disconected wired network (for purposs described above) wlan0 interface goes imediatelly up.


Code:

But in spite of this I am unable to connect to wifi access point (No encryption or MAC filter)

Code:
# works as expected and shows avaliable wireless network with approporiate channels
iwlist wlan0 scan

# echo $? return code 0
iwconfig wlan0 mode managed essid HTC channel 1


# But when i issue iwconfig I get Not-Associated under Acess point
[root@HP-PC ~]# iwconfig wlan0
wlan0     IEEE 802.11abg  ESSID:"HTC"  
          Mode:Managed  Frequency:2.437 GHz  Access Point: Not-Associated

          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
I think those problems could be related somehow, can something hold the network interfaces and not allowing system to use it ? I tried disable NetworkManager.service but no luck.

Code:
systemctl disable NetworkManager.service
systemctl stop NetworkManager.service

Configuration:
Code:
[root@HP-PC ~]# lsb_release -d
Description:	Fedora release 16 (Verne)
[root@HP-PC ~]# uname -a
Linux HP-PC 3.6.2-1.fc16.x86_64 #1 SMP Wed Oct 17 05:30:01 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
[root@HP-PC ~]# lspci | grep -i wireless

Many thanks.

Are you tethering using WiFi and Portable Hotspot or through USB? I'm a little confused by your post. Can you connect to anything from WiFi?

First problem is related to usb0 interface, I set up phone to USB tethering, but in Linux I cannot do anything with usb0 (newly interface that appears, it did not goes up).
Second (totally independed) problem is related to wlan0, I can set interface up but I am unable to connect to anything (AP or phone with tethering).

You might want to make sure you have the latest version of all relevant drivers. If possible, compile and install the latest stable kernel. I had a similar issue with a Ralink wireless card, updating the drivers fixed the issue. If you've never compiled a kernel before, don't worry, it's pretty easy. It takes some time, however. There are plenty of tutorials that can be found on Google, the latest kernel's source code can be found on http://kernel.org.

Hope that I have latest drivers system update is periodically scheduled, i would prefer less painfull method if it would be possible than compiling kernel.

After re-reading your original post, I see you're running kernel 3.6.2, so you probably don't need to compile a later one. Do you have a physical wireless on/off switch on your laptop? Also, try running the following command and posting the output:
Code:
 rfkill list
(you might need to install the rfkill package.)

You can try some of the suggestions here as well.

I have the HP Compaq 6715S (Same deal, just AMD chips).

There's a 2011 BIOS update which is needed for 3.x kernels on the HP site, and would probably help for this.
There's a BIOS option "Fast Ethernet Switching," which disables the wifi if the lan is configured, and vice versa. Make sure it is set in the negative. I would get NetworkManager out of it, because it knows better than you do what you want :-//.

The device not reappearing can probably be solved by unloading the appropriate module. I have slackware-14.0 here (XFCE, no NetworkManagetr) and an ante-delluvian HTC Android running CM-6.0, so I can probably duplicate and try here if you get stuck.

EDIT: If you need to insert a udev rule, most distros have /etc/udev for your personal scripts.

Thank you very much, "Fast Ethernet Switching" was the key, never heard of "feature" like this, people always learns something new. Now wireless (wlan0) is working as expected, however I still have problem with android usb tethering (usb0). I tried two phones HTC Desire C and HTC Desire S. With Desire C everything works as expected, usb0 automatically goes up and gains IP address (output bellow)

Also tried to reload usbnet module according your suggestion but no luck. What could be wrong ?

Looks to me like NetworkManager is getting in there and screwing things up because it knows better than you do what you are trying to do.

The 'server' in the tethering arrangement should be mode 'Master', whereas the 'client' is mode managed. I think NewtorkManager is purely a client control, but may be proved wrong.

You could try turning off NetworkManager and seeing if you can connect manually. Run these commands:

Code:
su
systemctl stop NetworkManager.service
ifconfig usb0 up
dhclient -v usb0
What this does:
1. Logs you in as root
2. Stops NetworkManager (you might lose your internet connection temporarily)
3. Enables the usb0 interface
4. Tries to get an IP address via DHCP. You should see a line like "bound to x.x.x.x -- renewal in xxx seconds". If it gives an error message, or it just repeats the line "DHCPDISCOVER on usb0..." repeatedly, then press Ctrl-C to stop dhclient.

To resume NetowrkManager:
Code:
 systemctl start NetworkManager.service
If you get an IP address with command #4, then NetworkManager is probably the issue. You can set NetworkManager to not manage usb0 if that's the case.

In addition, if the pc is the master, you just might need an iwconfig line specifying the mode
man iwconfig.

One is server, one is client, or relay, and I'm not sure which way you're doing it. A Caveat on that is that if you have the same broadcom b43xx card as I have, not all modes are/were supported in all drivers :-/. I tried to do something like this with an iMac, but that only had Wep, and the driver wouldn't handle Wep.

I think the wifi issue has been resolved, the current issue is USB tethering not working.

Is there a way how to debug "deeper" what is going on, or what you suggest ? Many thanks

Have you tried assigning usb0 an address? Maybe the driver doesn't support up/down? Try:
Code:
ifconfig usb0 192.168.0.1

NO way
Code:
[root@HP-PC ~]# systemctl stop NetworkManager.service
[root@HP-PC ~]# ifconfig usb0 192.168.0.1
SIOCSIFFLAGS: Cannot assign requested address
However this should be done automatically, PC should obtain IP, GW, DNS etc. from phone. I dont understand wtah is going on.
