My friend's DELL laptop suddenly can't find any available wireless network. It works fine before that and usually she can get a few networks available in her area. I have double check the wireless network card and try to turn on the Wireless Zero Configuration (WZC) feature on the laptop, but it still didn't work.
The problem solved when i apply the Fn+F2. This feature only apply for Dell's Laptop which we can turn the Radio on / off by applying Fn+F2. I think she was accidently off the radio on her laptop, and that's way the wireless card is disable and can't detect any wireless network.
However, i did learn new thing when i try to repair her wireless network connection. WZC is a feature available in Window XP. Sometimes, when the software come with your wireless adapter's manufacturer cannot help you to get the wireless connection up, you might wanna turn on the WZC feature in XP, so that you can use the XP's native support for wireless networking. It can be turn on by taking steps as below:
1. Start > Run> type "services.msc", and click open
2. Scoll down and looking for "Wireless Zero Configuration" service and select and double click on it to open up the propertise window.
3. Select "Startup Type" as "Automatic".
4. Click "Start" at the "Service Status".
5. Click "ok".
You can now have XP to manage your wireless connection.

Interested to get knowing your genetic Blueprint?
It is interesting to know, the technologies are now enabling us to sequence up our genome and understand our own genetic information from our 23 paired chromosome. However, to read trillions of copies of genome in a single human body is expensive. It may simply cost a million USD to do that. 23andMe, a private held company in California is currently working into this, so that the cost can be bring down to USD1000 with advance sequencing technologies. You can see an example on James Watson (co-discovers of DNA's double helix structure) personal genome's structure on this website: http://jimwatsonsequence.cshl.edu/cgi-perl/gbrowse/jwsequence/
I read about this in the NewScientist Magazine. Just wonder if they can sucessfully bring down the genome screening price to an affordable one, and also provide the information hide inside the DNA, there will be a new business market then. I mean, it is no point just get knowing the sequence and you can do nothing to change anything, rite?

Home Business?
Recently received quite a lots of "Home Business" or "Online Business" invitations through e-mail or read it in the forum that i often visit.
They sound real simple like you just need to subcribed / submit your e-mail address and read the advertisements sent to your e-mail. You will get paid when click the link provided and stay for a while at that website. When you introduced friends to the programme, you will share the profits made by your friends.
Some of the invitations even just lead me to a one page website, asking me to paticipate in the programme and start earning money without much explanation or description on how it actually works.
Well, i cannot deny that they are attractive. Reading those threads or articles or histories mentioned about people successfully get high income like USD4k-5k per month. I really doubt about the truth behind those wording, but its really attractive. HaHa. No doubt, i'm greed about whealth. My mind is like non-stop thinking about :"If it is so easy, why not i just give it a try?" But then, that is just for a moment. The next moment, i'm getting alert and remind myself not to get "addicted" to this kinda "easy online money making" programs. Although i did participate in 1 - 2 online business things, but they are like fulfilling my curiosity. I just wanna know wheather the programme is true or not :p
Just like my Mum always said,"You won't get anything without unless you work hard for that." An advise to friends, better concentrate more on your formal daily career! Cheers!

Window Can't Startup...Becoz IPOD connceted ?
Window Vista cannot startup with IPOD connected to it.
Do you experienced this before?
Last night i leave my IPOD connected to the PC when i shut down the PC. The next morning, when i tried to start-up the window (the IPOD still connceted to the PC's USB port), it stucked at the "Memory Test" status. I tried to reset the PC several times, it still cannot work.
I tried to check it out, and i noticed that the IPOD is connected to the PC and the power's light is flashing. Iunplugged the IPOD's USB , and the next time i restart my system, it start-up smoothly.
I never experienced this before when i'm using Window XP instead of Vista. Dun really understand why is this happend. But, the lesson is, better disconnect the IPOD safely before shut down the PC to avoid anything like this to happen again.

"rseb.sys" Problem Experienced with Vista
Yo! Guess what, i get a new PC together with friend last weekend.
Intel Core 2 Duo 2.0Ghz
G-Force Graphic Card with 512M Ram
Gigabyte Mother Board
160GB Seagate SATA Hard Disk
1GB DDR2 RAM
Samsung 20x DVD burner
Vista Home Basic
Just cannot wait to try it out, hehe it is my first time trying out the Vista.
This 1st thing i do, is install my PROLINK WLAN adapter's driver, so that i can get online. Everything seem working after the installation. As usual i have been asked to reboot my PC to get the new setting working, but when i reboot my PC, TA DA!!!!! I CANNOT EVEN GET THE WINDOWS STARTED...
It stucked at the page saying "rseb.sys is missing or corrupted" . Get real upset, becoz i'm using the microsoft wireless keyboard and mouse, and i haven't install their drivers, so the system cannot detect my keyboard & mouse :( Luckily, i still have the old PS2 keyboard at home, and i get to reboot the PC from last known good configuration.
When i surf the internet about this rseb.sys file, i get to know that this file is actually created by RALINK. I suspect that my PROLINK WLAN adapter's driver that i installed ealier is not compatible with Vista. So, i went to the PROLINK's website to download its lastest driver, and of course, Microsoft website to get the Vista compatible drivers for my keyboard & mouse too. After that, my problem resolved.
Then... i didnt live happily ever after, but i spend my whole weekend downloading drivers for my other gadgets -_-!!

MTU of a network
Last thread, i mentioned that one of my friend reduce the MTU size to enable MSN chatting when he is using IzzI to acces the internet. Below is what i get from Wikipedia about MTU:
In computer networking, Maximum Transmission Unit (MTU) refers to the largest packet (size in byte) that a communications protocol is able to pass onwards.
High MTU: Higher bandwith efficiency. However, for high MTU set for a slow interface, can block-up the interface and cause lagging on other packets.
Low MTU: Increase the number of data packet, which increase the routing decisions of a routers. Thus, slow up the communication.
I found that, if i can settle the problem by setting the PPPoE connection to static connection, then i should reduce the MTU. This will actually slow-up the whole network. I experiment his method by setting the MTU==576 at home, and online using a laptop and a desktop at the same time. I found that both of my PCs' connection are slow, and get disconnected quite often.
When i switch it back and using my own method (static PPPoE), the connection is faster and i'm able to play online game smoothly (althought there is a ~1 sec lag).
So to my point of view, to have the home network connect to the Izzi's terminal with a router. It is better to set the router to connect using static PPPoE and maintain the MTU==1400.

Connect router to IzzI wireless modem
My router model is D-link 624 (i know, its a bit out, is a discountinue product...)
This is how i succefully connect my router to IzziPro terminal.
1. I access my router UI through http://192.168.0.1/, and change the unit IP to 192.198.0.1.
2. I set my router to PPPoE access with the my izzi's username and password.
3. Set a static PPPoE IP range from 192.198.0.2 to 192.198.0.254.
4. Enable the DHCP of my router.
and, that's it. I'm able to connect a desktop, a laptop and a PDA to the router and online, and MSN chatting through izzi's network.
nice to share ^^
