Set up a wireless network without a router (Ad Hock)

Assalamualaikum wr.wb

Wireless networks are helpful because they let you use your computer and connect to the Internet anywhere in your home or office. However, most wireless networks use a wireless router, which can be expensive. If you have more than one computer, you can set up a wireless network without buying a wireless router and save yourself some money.

In a traditional wireless network, a wireless router acts as a base station, much like the base station for cordless phones. All wireless communications go through the wireless router, allowing nearby computers to connect to the Internet or to each other.

Ad hoc wireless networks work more like walkie-talkies, because the computers communicate directly with each other. By enabling Internet Connection Sharing on one of the computers, you can share Internet access.

Ad hoc networking might seem like a much smarter alternative to using a wireless router, but it does have a couple of disadvantages:
  • If the computer connected to the Internet is shut down, all computers that are part of the ad hoc network lose their Internet access.
  • To connect to the Internet, one computer always needs a wired network connection.
To connect your computers to the Internet using an ad hoc wireless network, follow these high-level steps (described in more detail later in this article):
  1. Enable Internet Connection Sharing on the Internet-connected computer. You can skip this step if you don't need to access the Web.
  2. Set up the ad hoc wireless network on the Internet-connected computer.
  3. Add your other computers to the wireless network.
How to enable Internet Connection Sharing
On networks with wireless routers, the router has the important job of forwarding communications from the computers on your home network to the Internet. On ad hoc networks, you must designate one computer to serve this role. The computer you choose must have a wired connection to the Internet, and it should be left on whenever you want to be able to use your other computers.

How to set up the first computer


To set up an ad hoc wireless network that allows computers to share an Internet connection without a router
  • If necessary, install a wireless network adapter.
  • Click Start, and then click Control Panel.
Start menu with Control Panel selected
  • Under Pick a category, click Network and Internet Connections.
Control Panel with Network and Internet Connections selected
  • Under or pick a Control Panel icon, click Network Connections.
Or pick a Control Panel icon page with Network Connections selected
  • Right-click your wireless network connection, and then click Properties.
Wireless Network Connection options menu with pointer on Properties
  • In the Wireless Network Connection Properties dialog box, click the Wireless Networks tab.
Wireless Networks tab in Wireless Network Connection Properties dialog box
  • On the Wireless Networks tab, under Preferred networks, click Add.
Wireless Networks tab in Wireless Network Connection Properties dialog box with pointer on Add button
  • In the Wireless network properties dialog box, on the Association tab, type the name of your ad hoc wireless network in Network name (SSID) box (shown in below). For example, you could name your wireless network MyHomeNetwork.
Association tab in Wireless network properties dialog box
  • Clear the The key is provided for me automatically check box and select the This is a computer-to-computer (ad hoc) network check box.
  • Create a 13-digit password and type it in both the Network key and Confirm network key boxes. For the best security, include letters, numbers, and punctuation. Then click OK.
  • Click OK again to save your changes.
Wireless Networks tab in Wireless Network Connection Properties dialog box

How to set up additional computers
If the computer you want to add to your network does not have built-in wireless network support, install a wireless network adapter.
Windows XP automatically detects the new adapter and notifies you that it found a wireless network.

Now connect your computer to your wireless network

Note: These steps apply only if you're using Windows XP Service Pack 2 (SP2). If you haven't installed SP2, visit Microsoft Update to install it before connecting to the ad hoc network.
  • Right-click the Wireless Network icon in the lower right corner of your screen, and then click View Available Wireless Networks.
Wireless Network icon shortcut menu with View Available Wireless Networks selected
  • The Wireless Network Connection window appears and displays your wireless network listed with the SSID you chose. If you don't see your network, click Refresh Network List in the upper left corner. Click your network, and then click Connect in the lower right corner.
Wireless Network Connection window Choose a wireless network page, with pointer on Connect
  • Windows XP prompts you to enter a key. Type your encryption key in both the Network key and Confirm network key boxes, and then click Connect.
Wireless Network Connection window, Network key prompt, with pointer on Connect

Windows XP shows its progress as it connects to your network. After you're connected, you can close the Wireless Network Connection window.

Repeat these three steps on each computer that you want to connect to your ad hoc wireless network.

Now you're ready to browse the Web wirelessly, from any computer you add to your home network.

Restart sound on Ubuntu (Suara Hilang....)

Assalamualaikum wr.wb
Saya mengalami masalah ketika menggunakan ubuntu untuk memainkan film VCD, musik atau lainya yang menggunakan suara, kadang-kadang ditengah jalan suara mati dan tidak mau kembali hidup kecuali di restart.  Setelah cari di internet saya menemukan solusinya...bagi saya ini berhasil, mungkin bisa anda coba bila mengalami hal sama.
Langkah-langkahnya:
1.  System>Preferences>Sound dan rubah semuanya ke ALSA
2.  sudo killall pulseaudio
3.  sudo alsa force-reload

Langkah lain bila cara diatas tidak berhasil:
sudo /etc/init.d/alsa-utils restart

Kadang cara ini juga tidak bekerja karena ada aplikasi yang error dan masih menggunakan sound card kita, maka lakukan:

farry@farry-laptop:~$ lsof | grep pcm
tuxpaint  30343      farry  mem       REG        8,4    22104    38019 /usr/lib/alsa-lib/libasound_module_pcm_pulse.so

dari data diatas ternyata tuxpain dengan kode 30343 yang membuat error, maka ketikkan perintah berikut:

farry@farry-laptop:~$ kill -9 30343
farry@farry-laptop:~$ sudo /etc/init.d/alsa-utils restart
 * Shutting down ALSA...                                                 [ OK ]
 * Setting up ALSA...                                                       [ OK ]

dan Alhamdulillah...berhasil, selamat mencoba.

Mengetahui Suhu CPU

Assalamualaikum wr.wb
Anda yang menginginkan tool untuk mengukur suhu cpu komputer anda, dapat menggunakan software gratis ini.

Reset Your Password

Assalamualaikum wr.wb

To get started, just boot your computer and when you see "Loading Grub" press the ESC (Escape) key. If you missed it, just reboot and try again.

Once you see the Grub prompt, press 'e' to enter Edit mode (as shown by the arow in below screen shot).


Next, highlight the line that begins with kernel and press 'e'.


Now, what you see may seem a little odd, but go the very end of the line, hit the space bar once, then type the following command after the word 'splash':

rw init=/bin/bash


and press enter, then b to reboot.

After Ubuntu has restarted, instead of loading the GUI, you will see a passwordless root shell. At the prompt, type the following command and replace 'username' with the name of the account you want to change the password.

passwd username



Type in a new password and retype to verify, once you see the confirmation that your password was updated successfully, reboot.

When GNOME loads enter your new password and you should be good as new again.
