How to make a Hotspot (without Ad Hoc) using your laptop Wifi

To create a hotspot the most commonly used way is to use Wi-Fi router to share Internet access to devices that have Wi-Fi facilities (laptop, Blackberry, Smartphone, PSP, etc.).

If we want to connect 2 computers that have Wi-Fi access we usually do is one server will be Adhoc while others become a client, but if we want to share our connection with the PSP for example, Blackberry, using Adhoc will not be detected by the devices , this occurred because they needed a more secure connection.


Technical facts: One of the biggest differences between the Adhoc and Access Point is that the Access Point mode allows you to actually share the Wi-Fi connection, the Wi-Fi cards are the same as you use to access the Wi-Fi networks. Ad Hoc requires internet connection coming from another card (Ethernet, cellular or Wi-Fi card in your computer the second).

Well, now we can use the laptop / PC that we usually use only to share the connection with another laptop, using the program called Connectify. The point of this program is we can change the Wi-Fi card on our laptops to become Wi-Fi Router.

First we download the program here first and then select the menu downloads.
After we install it, turn on Wi-Fi laptop then click the notification icon located near the clock, like the image below.

Then will appear like the following view

Wifi name: Name of the connection
Password: 8 characters password
Internet: Internet connection that we want to share
WiFi and Mode we left it default, after that click Start Hotspot.

Viola ... Turn on your device and then connect. Now you can use the Blackberry, Smartphone, PSP, etc. without worrying about spending your pulse or buy Wi-Fi Router.

Nvidia driver bug in version 196.75

KDH3BH3ZXF5U When I want to try to find the latest driver update for my NVIDIA graphics driver on the website of the official NVIDIA, i have a little curiousity to see the warning recommends that wrote for users who have downloaded the version 196.75 to uninstall it and go back to driver version 196.21 because it was found a problem with these drivers thus causing the cooling fan is not working properly.
After reading the official nvidia forums, many users have found physical damage on the graphic card for VGA cooling fan is not spinning at the maximum temperature of the card even has exceeded the maximum threshold. Some cards have confirmed the problem, among others: GeForce GTX 280, GTS250, GT220, 8800GTS, 9800GT. Fortunately the graphics card (G103M) my notebook was not included therein, and the driver was not wearing a version of 196.75. Although not all NVIDIA cards would be damaged by using this driver, check to be safe drivers on your computer and if the driver was using 196.75 version had better get back back to the previous driver. Because when referring to the Terms of Service NVIDIA, if the damage caused by drivers who had been released by NVIDIA for the beta or WHQL version can not be change.

Here's how to do the Roll Back:

To roll-back to a previous version you can open windows explorer, then right-click My Computer, select display adapters, then right-click the NVIDIA GeForce xxx, and select Properties. Then press the Roll Back Driver.

(To check your VGA driver version, see the last 5 digits driver version on the Properties window)

Review: Opera Mini Final Version 5

Opera Mini 5 Final has officially launched on 16 March 2010, after trying for 2 days I will try to review it when compared with the previous version 4.2. I did a test on my old mobile phone of mine, and also belonged to my family (Sony Ericsson K800) SE K510i, Nok 6300).
I wrote the following information taken from the Opera site, about the release of Opera Mini 5.

New features in Opera Mini:

* Tabbed browsing
* Speed Dial feature with thumbnails (Same as Opera Desktop Browser)
* Password Manager (similar features from version Opera Browser)
* Display a new, easy to use, and well suited for touch-screen phones as well phone with a keypad
* Download manager
* Opera Link

Changes from the Opera Mini Beta 2:
* More choice of languages!
* Russian language virtual keyboard for touch-screen phone
* Performance is better for low memory device (when compared with the version 5 beta 2)
* Improvement of the many bugs (weakness)

When first installed there was no reply problem occurs, just go to m.opera.com  in my browser phone, the phone recognized immediately and offered to install Opera Mini 5.
But after the download is complete, K800 asked if I want to overwrite the version 4.2 with this new version, based on my curiosity on testing version 5 so i replaced version 4.2. (So you can not install 2 different versions of Opera Mini)
The first time I was shocked to open the screen with the logo Telkomsel - Indonesian GSM Service (I use Indosat M3) after I browse on the Internet turned out to Telkomsel's work with Opera to new-service campaign. (Still, no reason to put Logo Telkomsel isn't it?)

For Browsing, almost no differences regarding the speed with the previous version. Then I tried Tab Browsing feature to open a Facebook page and Simple, but time to open the third tab page appears less memory message (out of memory), after I close the application and the application shMessenger reply was living behind the scenes. Then I tried to repeat again, there was no problem.
In this version I often experience hangs loading pages, connection failed, and out of memory reply that I rarely encountered in previous versions.
Then I see my feedback list (Feed), it lost all my feeds and I have to re-enter my feed address.

And when I would open my saved pages from Opera Mini 4.2 was not there at all, apparently saved pages from earlier version will not be able to read in version 5 of this. :)
Also when I want to change the font size, font size was almost equal to its largest size medium in beta, and 4.2.
Intrigued with the compatibility with older mobile I try to install opera in 5 SE K510i and N6300 mobile, when on the K510i, its performance is very slow, often hangs and can not be tabbed browsing. While the 6300 features not found landspace mode, when I browse the Opera proved deadly this feature in all versions of Nokia S40 because there are compatibility problems.
Sometimes the ads also appear, and there is a recommendation to install a version of Opera 5 beta 2.

So this is the following summary of the findings already discussed above :
* Telkomsel logo appear on all mobile phones to install OpMin 5.
* Tabbed browsing feature is nice, but you must have a fairly new handphone
* View less maximized if phone screen resolution less than 240x320 pixels
* Smaller font
* For Nokia S40 no landscape features
* Our old feed will not appear if the upgrade from version 4.2
* Pages that we saved from version 4.2 is not compatible with version 5
* Sometimes the ad appears and the wrong notification to upgrade to version 5 beta 2

My conclusion, Opera Mini is suitable 5 for newer phone (2007 and above), because it requires memory and good processor to maximize the tabbed browsing feature.

If you do not have a problem with the deficiencies as described above , you can upgrade your Opera Mini to version 5, but when youhave older phone you should stick with version 4.2.
