[SOLVED] update problem

elishac · 11-13-2009, 02:06 PM

Could you try:
Code:

iwlist wmaster0 scan

to see if that one comes up with something?

iwconfig results :
lo : no wireless connection
eth2 no wireless co
--> wmaster0 no wire co
wlan2 <quite a lot of stuff here : which line do you want?>

EricTRA · 11-13-2009, 02:23 PM

Code:

iwlist wmaster0 scan

did not give you anything either?

elishac · 11-13-2009, 02:29 PM

iwlist wmaster0 scan

interface doesnt support scanning

EricTRA · 11-13-2009, 02:35 PM

Ok, this means that your computer has wireless card, the commands can be executed, the network card to use for wireless is wlan2 but the scan comes up empty. Can you reboot your wireless access point, router, or whatever you connect normally to? And after that run the command like this again:

Code:

iwlist wlan2 scan

It should show output like below (this is from my computer, showing two wireless access point, from which one is mine)

Code:

iwlist wlan0 scan

If the scan comes up empty again, then you'll have to connect with a cable because I don't know why it's failing.

Kind regards,

Eric

PS: after rebooting your wireless access point or router you'll probably need to wait some time to run the command on your computer. It might take some time for the access point to startup.

ok, it works now (i had manually disabled wireless, sorry for all the trouble).

so, iwlist wlan2 scan shows a lot of things, most of which i can't read (out of screen)
which one do you want

elishac · 11-13-2009, 02:52 PM

actually internet works as well. omg i'm so sorry.
let's go back to the lines where i was supposed to download stuff.
what do u want me to do now?

EricTRA · 11-13-2009, 02:52 PM

Do you know which one is yours? Then write down the ESSID and the address.

Then next run the following commands:

Code:

iwconfig wlan2 essid "Your ESSID"
iwconfig wlan2 key "Your_key"
iwconfig wlan2 ap 00:00:00:00:00:00 (the 00 address must be substituted by the address of your wireless access point)
iwconfig wlan2 up
dhclient

The quotes around the ESSID key and your_key must be typed also.

Normally if everything is working correct and you don't get any errors, you'll be connected to the wireless router.

Next step is to check if you have internet connection, and then the steps as discussed before (the apt-get install grub2 post).

Kind regards,

Eric

elishac · 11-13-2009, 02:55 PM

ok, so i wrote sudo apt-get install grub2, and it said the same thing is before.
what do i do now?

Are you saying everything is up and running and that you have connection to the internet via wireless? If so GREAT.

Go back to the post #98 and execute what's inside the quote box (the install grub2 part).

Kind regards,

Eric

to install the necessary packages and go to the next command when it finishes.

When going on to the next step carefully read the words in red in my previous post, or you'll f**ck up your system and boot with an error 15.

Kind regards,

Eric

elishac · 11-13-2009, 03:08 PM

i wrote yes.
i got a blue screen untitled configuration of grub-pc.
configuration of packages tool

it says :
a standard installation of grub was detacted in boot/grub
in order to replace this installation, it is advised to modify boot/grub/menu.lst to chaiload grub 2 from the standard installtion of grub. please choose if you want to do this modifcation.

it is recommanded to choose this option to be able to confirm the well fonctionning of grub 2 before installation it directly on the master boot record
in any case, to load grub 2 directly from the mbr, you should use the following command with the administrator status :
upgrade-from-grub-legacy

<ok>

shall i press enter?

EricTRA · 11-13-2009, 03:11 PM

yes, press enter.
