Sorry for the late response; I don’t check the comments on my blog very often.

You said that you had been using Ubuntu on your laptop for over a year and the problem has had to do with your wireless adapter. In my own personal experience I’ve found that applying updates clears issues like this up about half of the time, but of course the question is how do you access these updates.

You have a few options. Considering that this OS has not been updated in over a year (?) I would suggest you consider backing up your entire Home folder and reinstalling from a copy of the latest version, or at the very least run the Live CD to see if it has out of the box support for your wireless adapter before deciding to backup and reinstall.

The next option is to use the Ethernet port on your laptop to directly connect your laptop to the router. Ethernet ports are often better supported out of the box and should allow you the ability to check for and download updates. With the number of distribution updates that may span between your current version and the latest distribution version of the OS, the time it takes to download and install all these updates could span over half a day of your free time. So word of caution.

The last option is the same as the second, or an alternative to the second if it’s not an option, and that is to purchase an USB wireless adapter that is known to work well with Ubuntu. Your options will depend on where you’re shopping and what they have to offer. I would advise shopping locally so if the adapter you get doesn’t work you can return it quickly and exchange for another. Unfortunately all adapters are not alike so compatibility is a coin toss (but the odds are in your favor).

Best of luck to you!

Thanks for visiting my blog.

One of the things you should do after installing Ubuntu is connect it to the Internet and download all the latest updates for the OS. I know that you said you only have a wireless adapter on the system now so what you should do is find some way to physically connect it to the router using an Ethernet cable, just for the time being. Sometimes wireless adapters will suddenly work after installing all of the latest updates. If not, the next thing you can check after upgrading and restarting your system is the Hardware Drivers manager. If you are using 10.10 or older, you can find this in the System>Administration menu. If you are using 11.04 or newer, just click the top left menu button and begin typing “hardware” into the search box at the top and you should see a shortcut appear. Inside this utility you may find that there are proprietary drivers available for your wireless adapter that can be “Enabled”. Once you enable a driver, Ubuntu will download and install it for you.

If none of the above works you can also try using a program called ndiswrapper. This utility will allow you to use Windows-based drivers to use the wireless adapter. You can learn more about ndiswrapper here:

Sorry for your troubles.

This is an old post, and nobody I know of still uses wifi-radar to establish a connection. The built in “nm-applet” utility that auto-runs on the latest version of Ubuntu works fine for most.

If you are trying to connect wirelessly, several things might be stopping you but the biggest ones are:

1. Proprietary drivers for your wireless adapter need to be enabled/installed.

2. Your laptop (if it is a laptop) has a on/off button or switch for your wireless antenne that needs to be ticked in order for Wireless connectivity to be made available.

3. Related to the second item, your computers BIOS may have a feature in it that defaults the wireless adapter to be off when you turn the computer on, requiring the Operating System to take control of turning the device on and off. You want it to Always Be On.

To check and see if you have drivers available for your wireless adapter, you should take the computer to a hard-line (Ethernet) connection for the Internet and run System>Administration>Update Manager. Then download all available updates. Then visit System>Administration>Additional Drivers (in versions older than 10.10 it’s called System>Administration>Hardware Driver Manager).

Also, simply applying system updates alone may do the trick. If all else fails, please email me directly.

What am I suppose to do from here? I am soo lost.

Hope you can help.

Just to clarify, the — in front of the word “configure” in the above command should be two individual hyphens. WordPress presents it here differently.

sudo dpkg –configure -a

but he shares the network in a large group and the provider using mikrotik server
in windows there was a login page automatically opens when he tries to open any website he type the login name and the pass and go on
but on ubuntu that login page did’nt come up and ofcourse there is no internet connection
note that the pc is working with the internet good with any other network without that mikrotik

thanks for your help

If you are attempting to connect to a secured (encrypted) wireless network, you have to know the passwords in advanced before the network will grant you access. You can obtain this from the owner of the wireless device you are trying to connect to. If you are trying to steal the Internet from your neighbor and they all use encryption, you should purchase your own Internet access from a local ISP, or visit a public place (like a coffee shop, hotel or library) that has free wireless Internet access available to you.

The only other password prompt that may appear is the keyring manager. It is intended to help you manage multiple passwords to different things, including wireless networks. This will allow you to store many passwords behind one master password. However, you do have the option of not setting a master password, which will allow your computer to connect to a secured wireless network automatically provided you’ve connected to it once before and the password has not changed since your last connection.

You type your password. You will not see any asterisks ***** appear while typing.

Firestarter can be installed via Applications>Add/Remove>Search for “Firestarter”.

To get it to run when you boot, click System>Preferences>Session. Click on the Add button, then in the “command” line, type “firestarter” all lower-case, and you should also name it firestarter as well. Once you have those two fields populated, click ok, and that’s it!

You should set your address to be static, and you should also manually set a DNS resolve address in Ubuntu by doing the following in Applications>Accessories>Terminal:

sudo gedit /etc/resolv.conf

This will open the resolv.conf file in Gnome Text Editor with root privlages. On the line “name server xxx.xxx.xxx.xxx” replace the x with the IP of your name server (obtain this DNS address from your router, or your Windows PC attached to it by throwing a ipconfig /all at it). Then save the config file with the new name server address. After that, you can restart your network components by typing:

sudo /etc/init.d/networking restart

Also keep in mind that if you assign a static IP address to a computer that it has to be within the same network “broadcast domain/subnet” as the rest of the network you’re wanting to communicate with. Simply look at the IP address that is being assigned to the bridge (may have to see it’s config, or look at the routers “attached devices” status to see what it’s getting). If the bridge is being assigned 192.168.1.226, you should assign your computer an ip address of 192.168.1.227, with a subnet mask of 255.255.255.0, and a default gateway… try the IP address of the bridge first, and that should do the trick.

Good luck!

Thanks!
