ok this is the info that I have gathered you have two wifi devices one is internel and the other is the usb both of which do not have all there mods loaded. the interneal one is capable of scanning so I think that is has some thing to do with the mods but not sure. Like I said I am do not know this card. I am sure that some one come along that is more experienced and will be able to help you out.

estebe
May 3rd, 2011, 10:25 PM
thanks for all your time. :D
where can you see that i have
two wifi devices? i'm sure that i havve only one....
sure someone else can help me!

estebe
May 4th, 2011, 04:24 PM
today I have take out the wpa security and now is connect! so is clear that the problem is on how to manage the authenticcation wpa/wpa2.

can someone give me some light on this matter?

If you see my previous post, i have, at the output of iwlist, two networks with the same name, this is because i have a range expander from linksys.

thanks in advance

I had the same problem a couple days ago. But I had just installed Ubuntu 10.10 and was setting up my wireless for the first time. Try installing WifiRadar or look under ubuntu packages for Network Manager. I was under the impression it was already installed and that I just couldn't find it. When after it was all said and done I never had it.

If you are trying to setup your wireless connection through the network program already installed on your system, give up. Look up WifiRadar, I'm only about one week into Ubuntu and it was super easy for me :)

Just make sure you have the correct drivers installed, and wifiradar will be a breeze!
[Edit If iwlist shows any results your drivers are probably installed just fine]

estebe
May 6th, 2011, 07:25 PM
hi again,

i have installed first wifi radar, but i do not like it, then i tried with wicd, and always says: password incorrect (but password is ok).

anyone has the same problem as me? i'm :mad: getting nervous with this matter

estebe
May 9th, 2011, 04:26 PM
I have tried with wep password but the same result. so it the system is with no security I can connect.
:confused::confused::confused:

this is "una mierda":-x

josephmills

try and reset your router and your network card
/etc/init.d/networking restart also if the handshakes and not happen (wpa/wpa2) we could try and crack the password on wep to see if that is the troubles also but I would try to restet the router (button on the bottom of it) What kind of router is this? but I think that it is your firmware or mods that is the trouble

estebe
May 9th, 2011, 05:41 PM
Hi, again.

I've already done this. so I think that is something that works different than on 10.10. the router is a huawei HG553 from vodafone.

estebe@WSTestebe:~$ modinfo vt6656

Is this possible? Now i'm connectting without safety...but connect to internet

josephmills
May 10th, 2011, 06:59 PM
so you are connected but with no security code? If this is so
open your terminal and type in
sudo apt-get install wpasupplicant is it all ready installed? if so go to synaptic then type in wpa do you see the wpasupplicant? Mark it for removal then reboot then reinstall it then reboot then sign into your router and change the security to wpa2 try to connect nothing drop it a level anything no repeat yes Great

estebe
May 10th, 2011, 07:38 PM
I've already this packet installed on its newer version.

what i mean is that i can connect only if my router has no security. i tried with wpa and wep with no success.

should i have some module call vt6656?

yes you need that those mods to load it is your driver for the wireless card

joseph, i found this



estebe@WSTestebe:~$ modprobe -l | grep vt

estebe@WSTestebe:~$



this seems that the kernel has the driver,

Has anyone works with this on unbutu 11.04 or is my computer fault? I'm using a zotac gforce 9300 motherboard with this usb wifi card vt 6656

I have exactly the same problem on a Dell Latitude D630 using an internal Intel wireless adapter. I can connect to unsecured networks but not secured.

Same problem here, also on the Zotac GeForce 9300 mobo with "onboard" wifi via a VIA VNT-6656 dongle. Worked fine on 10.10, only connects to unsecured networks with 11.04. Makes me wish downgrading was easier!

Any more ideas on how to further narrow down the issue?

originofstorms
May 13th, 2011, 11:18 PM
I tried booting with the 2.6.35-28 kernel from Maverick, and it appears to work fine. Seems like there's a regression in the vt6656_stage driver somewhere between 2.6.35-28 and 2.6.38-8. We should probably report this problem upstream, but I'm not sure where or how. Anyone?

There's already bug for this. Please mark it 'affects me' if you are affected -- hopefully it will speed up the resolution time...

I'm having the same problem...

I recently bought VIA Artigo A1100 with this vt6656 wireless card. I tried the following versions of ubuntu, not a single one like to work with this wireless card.

12.04: Installed. Can use wired connection. Cannot use wireless.
followed instructions here: https://help.ubuntu.com/community/WifiDocs/Driver/vntwusb
failed at:

$ sudo dkms build -m vntwusb -v 1.20.03forgot the exact wording, but something like "Kernel gave unexpected return value".

10.04: Can boot, but screen messed up, cannot install.
11.04: Live CD (or Live USB rather). Can use wired connection. Can recognize wireless and see network but cannot auth even though correct password is entered.
I found this post and become frustrated :sad:

Edit: Upgraded to 11.10 and installed Wicd Network Manager (Disabled the built-in network manager). And now it works perfectly !!
