WiFi connection

Hi

I have brought my own laptop into work (for some free WiFi ) but it cannot find the connection. My little netbook finds it straight away (ubuntu 10.04) but my Toshiba Equim (Ubuntu 10.10) can’t. How do I search for it?

Thanks

If your wireless drivers are working, and the network is broadcasting it’s SSID, then all you should have to do is click the wireless icon on the top panel, and the network should be listed.

Who set up the netbook ? … what I’m trying to find out is… is the wireless network transmitting its SSID, or did someone have to enter it manually.

For security reasons, the companies wireless may not be broadcasting its SSID, and may also be using MAC address filtering… ie. you’d need to KNOW the SSID, and may need your laptops MAC address adding to the list of devices allowed to connect.

but in answer to the original question… to see available wireless networks:

iwlist wlan0 scanning

Where wlan0 is the name of your laptops wireless interface

you can get the wireless interface name with:

ifconfig

It used to pick up any wifi in the area now it wont show anything. My netbook has an icon in the toolbar with what is available and is currently showing 3 connections (Ubuntu 10.04).

Can you send the output from these 3 commands:

ifconfig
iwlist wlan0 scanning
sudo lshw -C network

No, because I can’t get the internet on that machine. I have them both up and running with my netbook being the only machine to find a connection.

Does your laptops wireless work ANYWHERE… if not then either you’ve turned wireless off. or it’s a driver or hardware issue, so I’d need the output to check.

Does

iwconfig

show an active wireless connection ?

iwconfig

lo no wireless extensions.

eth0 no wireless extensions.

You haven’t given your wireless connection a static IP address at any stage have you?

Does your wireless work at home with the laptop?

I have not given a static ip, not intentionally anyway. I have just taken out my broadband in favour of a dongle which is recognised but does not work.
