See man wpa_supplicant for available drivers...

justmy2cents,

Killing this makes no difference!

Code:

auto wlan0
iface wlan0 inet dhcp

To autostart the wifi. Had disabled this earlier and the searching for wifi networks causes boot-up to stall for over 10 minutes. Goes immediately without.

Help please!

as far as I know it is one or the other.

I had a linux os using Network manager (applet) and wicd
I have a linux os using Network manager and Oh Hell I do not even know, haha. but it works. you cannot mix them though is all.
Wicd
and
wpa supplicant

All,

Since I'm clueless on wifi networking would like to disable wpa_supplicant and Network Manager to see if I can resolve this with wicd.

I use to have a system that used a wifi link via high gain antenna, on wlan0, and then was PDC so served as DHCP server on eth0 and could only resolve all the issues with wicd so think it should be my choice here as well.

Do you guys agree?

If so want to disable the other 2 without removal, till I get this right then and only then remove them.

Cheers!

I can find and kill wpa_supp with:

Code:

ps -A | grep wpa_supp

But cannot find network manager as it runs under a different name!

Cheers!

That wouldnt help cause like I said such programs use wpa_supplicant as the back-end their front-end.. The wicd-daemon depends on wpa_supplicant, you can verify that's the case if you type apt-cache showpkg wicd-daemon.. I would keep trying wpa_supplicant with the
-dd option which increase debugging verbosity and provide a little more insight into what the output is refering to as it's trying to connect.. Also I would check dmesg and grep for your wireless card driver and interface... Get your wireless card driver info by issuing lspci | egrep -i --color 'wifi|wlan|wireless' and then lspci -vv -s 06:00.0 (get your '06:00.0' from the previous command)..

justmy2cents,

None of your ideas, though good, address the problem. Already know wifi is connecting, so no problem with the RF side of the connection. The problem is somehow dhclient is misconfigured or just not working, thus no IP assigned and therefore no communications. Even direct ping to google's known/shown IP doesn't work, because if not IP is set on wlan0 it will not communicate, even with the RF section of wifi connected.

I tried purging dhclient, to re-install but dependencies with WireShark and 2 other apps would not let purge go through. Documenting those as may need to purge them as well to clear this issue.

Guys,

I don't know which command to execute to show the connection is up and workin but dhclient not working other than what I see. I get the lower right popups that show:

Connection found,
Establishing connection
Connection established.

the the connection button in wicd turns green
but can never ping. Don't get any errors from dhclient
but:

Code:

ping -c 3 www.google.com
and
ping -c 3 172.217.12.60
or
ping -c 3 8.8.8.8

all yield

Code:

3 packets transmitted, 0 received, 100% packet loss, time 2016ms

So you can see I have connection but no IP so cannot actually connect without the IP assigned!

I also ran:

Code:

Ifconfig wlan0

which shows IP as 192.168.43.147, which is a local network IP and it shoul be showing a non local IP. Assume something there is the problem.

All,

OK here is how I know the connection is working and we are at the DNS level:

Not Connected:

Code:

   cmd: ping -c 3 www.google.com
Result: unknown host www.google.com

Connected:

Code:

   cmd: ping -c 3 www.google.com
Result: --- www.google.com ping statistics ---
        3 packets transmitted, 0 received, 100% packet loss, time 2015ms

What else I know, that may now be pointing to my phone as the problem area:

Code:

I just got inet connect to my house after 6 months no service.
I can run wired.
I can connect and ping through my Netis wireless router, so DNS seems to be working OK.

Conclusion:
I'll mark this closed as I now can connect and ping via the Netis router, and will open a thread on this at the Android forum, as this appears now to just be an issue with the WIFI hotspot on my phone.

Cheers!
