ACER NETBOOK HELP REQUIRED ASAP.
Hi guys looking to pick your brains. My daughter has a Acer netbook got it on a deal from Eircom last year. Basically it won't connect to the internet for me, it did before no problem and had to get my router replaced as it was faulty. It runs on a linux system and when i double click on Network connections nothing opens, its as if the file is empty. There is no flashing screen in the bottom toolbar any more either. I get a sneaky feeling she may have be messing around and has deleted a file. As its a netbook it came with no disks or anything, to like reinstall stuff. Just wondering does linux have the windows equivelent of system restore or something.

Any help greatly appreciated as she loves the thing and is lost without it.
Posted over in laptops too to try get to the right person who can help cheers.

Try this:

press ALT + F2
A window will appear with a textbox
type "nm-applet" in to the textbox and press enter/click ok


********************************************************


If this does not work press ALT + F2 again
type "terminal" into the textbox and press enter
A terminal window(a black text only window like DOS/command prompt in Windows) will open
type ifconfig
You should get something like this:

[username@localhost ~]$ ifconfig

for the wifi connection, there should be something like "wlan0"

if there is type

ifup wlan0

Hi i did everything and the only thing i see is wifi0-00 if that means anything to you. The ifup wlan0 command doesnt do anything but says cannot be found

duffman85

if wifi0-00 has text similar to the text to the right of "eth0" in my previous post then wifi0-00 is the name of your wireless card

As before all these commands are typed in the terminal.

You can try typing

ifdown wifi0-00

and then

ifup wifi0-00

If nothing happens you might have to be "root"(the Administrator user) by typing "su" or "su -"
typing "ifconfig" to see the network configuration information.
The line highlighted in bold is the important it should say "UP"

"ifdown wifi0-00" will stop/turn off the network card/wifi
"ifup wifi0-00" will turn it on again
This is what I have done below.

1. Become root by typing "su -" and entering the root password(this may be blank on the Acer (I don't know).
2. typed ifconfig to show the configuration information
3. typed ifdown eth0 to turn off eth0(the wired network card)
4. typed ifconfig again to show that the entry for eth0 is now gone
5. typed ifup eth0 to turn eth0 back on
6. typed exit to go back to being a normal (non-administrator user)

If you get no joy try here:

bman

Also, are you sure your router is working and is broadcasting an essid? Have you other wireless computers in the house and are they able to connect to the router wirelessly?

LINPUS is the OS on them

don't forget to check the wifi switch too

can't find the picture guide to add new wifi connection , it's the third one down in the list IIRC
