จากบทความก่อนนี้ ได้ทำการเพิ่มAUX ให้กับวิทยุเดิม พอดีหากเรามีตัวแปลงUSBที่เสียบที่จุดบุหรี่แล้วจูนคลื่นให้ตรงกับวิทยุเรา ซื้อมา350ปรากฎว่าใช้ใด้ ห่วยแตกมากคลื่นรบกวนไม่ชัดอีกต่างหาก ก็เลยจัดการรื้อมันออกมาเพื่อเอาสัญญาณ Audioก่อนที่มันจะทำการ Mod เป็นคลื่นวิทยุ ต่อกับช่องAux โดยตรงเลย เสียงที่ใด้ Ok เลยแหล่มมาก

สิ่งที่นำเสนอนี้สามารถนำไปประยุกต์ใช้ได้กับ รถยนต์ทุกรุ่น หรือ จะเป็นเครื่องเสียงที่บ้านก็ได้ครับ

เริ่มเลยนะครับ(ต้องขอโทษใว้ก่อนเลยเพราะใช้มือถือถ่ายตอนกลางคืนเลยไม่ค่อยชัด)
1.ต้องทำการเพิ่มช่องAux โดยดูจากกระทู้นี้เลย

2 จัดการซื้อตัวแปลง USB ที่เสียบกับที่จุดบุหรี่รถ รู้สึกว่าตอนนี้ราคา250(เอาแบบไม่มีเมมในตัวจะถูกไม่งั้นจะแพงกว่านี้หลายร้อย) หน้าตาตามรูปเลยที่พันทิพย์ ชั้นบนๆที่มันใส่ลังขายเยอะๆ

1. Do not name your SSID your last name or first name

2. Do not have your pass phrase your last name of first name

3. Don’t leave your wireless channel at six, change it to 2 or 11

4. Don’t leave your wireless network open enable some sort of encryption

5. Place your wireless router in the middle of your home not next to a wall

6. Don’t place your wireless router next to large heavy objects

7. Configure your laptop not to automatically connect to a wireless networks named “linksys”

8. Don’t leave your passphase the same and change it every couple months

9. Don’t use only WEP encryption, enable WPA2 and your wireless network will be a lot safer.

10. Don’t use AES wireless encryption for wireless gamming it does slow your network down.

11. Don’t start configuring your wireless network until you have upgraded your wireless router firmware

12. Don’t purchase anything but wireless MIMO routers for home networks, MIMO routers will give you better coverage.

13. Don’t leave your transmit power at the default transmission level. If you need a strong signal turn it up, if you don’t turn it down to the minimum

14. Don’t place your wireless router in the lowest spot in your house. Place it as high as possible to give you the best coverage.

15. Don’t have your wireless antennas pointed in the wrong direction. Meaning your signal does not emit from the points, they emit from the sides.

16. Don’t expect to achieve those 108 mbps speeds that are advertised with MIMO routers.those speeds only are achieved under super ideal circumstances.

17. Don’t upgrade your wireless routers firmware over a wireless connection

18. Don’t upgrade your wireless routers firmware until you have reset your options to the defaults

19. Don’t confuse an access point for a wireless router. Wireless routers act as a firewall, access points do not.

20. Enable some sort of security on your wireless router, if you don’t you will be sorry

Ok, so you decided you want or need a wireless phone.
You have some idea of what you want. But oh, the choices
and decisions to make!

Selecting a phone is not so bad but all those wireless
plans is just absolutely confusing. Believe me you are not
alone, wireless plans are probably the most confusing
aspect of this entire market.

In fact, there are books that are written just on this subject
alone to help unravel all this confusion that providers sell.
So let’s get started and try to give you some basics on
finding the best plan that will suit your style and your
budget!

There is a huge selection of wireless phone plans to
choose from today. But the question is, how do you
choose the best wireless plans?

Dependent on your location, you could have as much as
five or more providers that offer services in your area and
each one has a variety of plans for you to consider,
according to your needs and intended usage.

It is very important that you do your homework before
meeting with a provider so you know exactly what you
need them to offer you.

Lets take a look at what you need to consider.

It is critically important that you know how much local,
regional, and national coverage you are going to need in
your plan.

If you travel alot out of your region, you probably should
consider one of the nationwide plans in order to be
covered. Once you have decided on the coverage you
need, then you need to consider the number of minutes
you can expect to use each month. By looking at previous
bills or prepaid card receipts you should be able to work
this out fairly easily in an effort to find the best wireless
plans.

The size and type of phone that you need is usually
determined by the options you want to include. If you are
planning on using the phone to send and receive email,
then you will need one of the higher-end phones that are
Internet ready and that comes with a plan that offers
economical rates for data transmission.

If you do not need internet access, then you can get all the
features you need in a phone that is much less in price.

Frequently, service providers offer you a reduction in the
cost of the phone with the purchase of their plan. The best
wireless plans generally are either a one-year or a two-
year contract.

But before you sign up for service, be sure you have a
clear understanding of the terms of contract termination.
This is critically important!

If you have to move or break your contract for whatever
reason, there can be and in every plan I have studied a
sizeable penalty which can at times be equal to the
monthly repayment multiplied by the number of months
remaining on the contract, so it is important that you know
and understand every part of the contract before you sign it
and are aware of any exit clauses that exist.

I can’t stress this enough. Thoroughly read and understand
your contract before signing. You certainly don’t want to
have Murphy’s Law kick in and find out that you have to
pay two hundred or more dollars to cancel your service.

When it comes to a wireless standard, the first thing we all look at is how fast will this baby run! And you know the trade-offs, you can spend a lot of money to get the fastest thing running, or you can back off a little and save a lot.

The good thing about wireless networks is that the price difference between wireless standards is almost gone. There are some things that could add up, but I will explain the difference and why you might want to go that route or not.

Now, let’s get to the different wireless standards you can choose from.

1. 802.11b - 11Mbit at 2.GHz

2. 802.11a - 54Mbit as 5.0GHz

3. 802.11g - 54Mbit at 2.4GHz

4. Hybrid Systems

When you get ready to purchase your equipment, you will see a lot of systems saying that they are faster than these standards listed above. Most will say 108Mbit per second, some 125Mbit per second and a few even higher. To operate at these speeds usually requires you to only use their network cards to access their access points, some of them require a specific card from them to get that speed. If any other card connects, then they will drop back to the standard speed and you lose the extra speed you probably paid extra to get.

What Should You Get

I was purchasing equipment for a completely new wireless setup. We only had one older wireless computer and I replaced the card in it with a new one. I did purchase a system that advertised the 108Mbit speeds since I knew who was going to connect to it.

If you are building a new network setup, I suggest you purchase a system that will run faster than the standard, but only if you know who is connecting. If not, then get a system that runs on the 802.11g standard. The price is about the same as 802.11b but runs 5 times faster.

Many small businesses have considered connecting computers and other devices to their corporate network via wireless (WiFi) connections, and a brave few have actually done so. Many of these early networks required that wireless devices be carefully placed within the building so that the wireless signal reached all intended recipients. Typically, these networks lacked adequate security features, which left them vulnerable to information and resource theft by unauthorized persons. These two problems have now been largely solved, meaning that it may be time for more small businesses to look into the potential advantages a wireless network can offer.

Wireless Networking Basics

Building a wireless network requires two distinct types of hardware components, wireless access points, and wireless access cards. The wireless access point is a device, which is attached to an existing computer network via a standard Ethernet cable. It has an antenna on it, which allows it to broadcast and receive signals from PCs and other devices. Each device wishing to communicate with the access point needs a wireless access card, which also contains an antenna. The current wireless standard, called 802.11g, allows for up to 54 megabits of data per second to be transmitted between the desired access point and the access card. While not quite as fast as wired networks, which typically run at 100 megabits to 1000 megabits per second, wireless networks offer more flexibility, and can be less expensive to install. This is especially true for older buildings where installing cable can become cost prohibitive.

Cutting Corners

Wireless networks use radio frequency waves to transmit information, and thus they are susceptible to being blocked by walls and other obstructions in a building. These obstructions can cause “dead zones” where the radio waves are unable to reach their intended recipients. Microwave ovens and other radio frequency emitting devices can also wreak havoc on wireless signals. The solution is to place your wireless access points strategically around your building so that interference is minimized. When the distance from a wireless access point to the wireless device is more than a few dozen meters, wireless repeaters can be installed to boost the signal. These repeaters can also be placed so that the wireless signals can be accessible from all corners of the building.

Wireless Network Security Solved

Installing a simple wireless network is pretty straightforward, but installing a secure wireless network can be substantially more difficult. However, an Ann Arbor company called Interlink Networks now offers their LucidLink products, which make installing comprehensive wireless network security a snap. Before LucidLink became available, an organization wishing to lock down their wireless network would need to hire expensive network security consultants to install and manage the wireless portion of the network. LucidLink packages all of this expertise into a software add-on that is so easy to use that even a small company’s office manager can easily take control over who is accessing the company network via wireless. It goes above and beyond simple address authentication (standard with most wireless routers), and implements what is called a RADIUS server. RADIUS servers are what large organizations spend thousands of dollars installing and maintaining in order to secure their large (1000+ node) wireless networks. Until now, installing a RADIUS server was out of the price range for all but the largest companies. In contrast, LucidLink’s product can be purchased for as little as $99 for a 3 user Home Office Edition, $449 for a 10 user version, and goes up to $3995 for a 250 user version.

Summary

While there are still issues with making sure that all areas of a building are covered, the current WiFi standard (802.11g) has a more powerful signal, meaning less emphasis needs to be placed on the locations of attached devices. However, it is still recommended that a professional site survey be done to verify that all required areas of the building can be reached by the wireless signal. Meanwhile, Interlink Networks has finally solved the security problem at a price that is affordable for small and medium sized business.

Wireless networks using 802.11 have made it simple to connect multiple devices to your home network.This can also make your data availiable anywhere, even outside your home.To set this up all you need is a broadband connection connected to a wireless router or a WAP Wireless Access Point. Your home computers should have wireless access cards installed or if your using a laptop a PCMCIA wireless card. Intel Centrino is great for wireless, I personally use it. I like the fact that I did not have to purchase additional hardware.

When you set up your wireless router or WAP your signal is broadcast. This broadcast usually goes further than your home or business. People like to drive around finding unsecured wireless access points. This is known as Wardriving, some hackers even mark spots on the sidewalk to let other hackers know your home or business is offering free Internet service, or worse yet access to your data.This is not to scare you but make you aware.

Diasble broadcasting so people cannot you your wireless network.

Your routers come with pre-configured system ID’s its called a SSID or Service Set Identifier, its very simple to locate this information on the Internet for default SSID’s I recommend changing this to something hard to guess.
Use alphanumeric’s to make it even harder to guess.

Use encryption to protect your network. WEP or Wireless Encryption Protocol is not secure, I have cracked my own network with a Linux machine running Kismet. WEP’s keylength is only 40 bits, once you collect enough data from packets its only a matter of time for a determined cracker.Instead use WPA which is WI-Fi protected access. This is more secure.

Configure your router to block incoming outgoing traffic you do not use. Consider blocking Port 23 Telnet and Even FTP.

Router manafacturers have default passwords which I find many home users do not change. CHANGE THEM!

Invest in a software firewall and keep your system up to date. In the month of October 2005 there have been several
security flaws listed by Microsoft. Keep Informed.

Many consider wireless as one of the greatest inventions in the history of mankind. Some would even compare it to sliced bread. For them, wiring up a network is just as easy as slicing one’s bread.

The biggest benefit of wireless is that it makes things simpler. You’re not bound by wires to connect your computers at home or at the office. The computers are connected to the network with the use of wireless technology using radio signals.

However, some ask, “Why is there a need for a wireless network?” The following are some good reasons:

Internet Access Sharing

Wireless offers an affordable and easy means to share internet connection with multiple PCs. This usually will not require more than one modem. Also, you can add additional computers to your network by simply plugging in the wireless card and switching them on. Then, they too can have an internet connection.

Sharing Printers and Files

Wireless networks also offer easy file access regardless of which part of the house you are in. It allows easy transfer of the files between your laptops and desktops.

Always Connected

One reason for broadband today is that, you can have an always on connection to the internet. And wireless networks complement this fact. Wireless network technology runs at speeds far greater than broadband internet access easily connecting multiple computers to the internet simultaneously.

Wires? Set them aside

This would be the most important reason to change your old network to wireless. We all know, wires are inconvenient, dangerous and ugly.

Wireless means no more wires. There will be no spaghetti on your floors and corners anymore. This does not only improve the security of your house, it also lessens the danger of tripping or fire.

Play Internet and LAN Games

Wireless LANs allow your entire family is to play a game together without needing to bring your computers closer together. You could also invite other opponents such as your friends and ask them to bring their own PCs. With the wireless network connected to your PS2 or Xbox, playing an online game goes to a whole new level.

If you plan to buy a wireless router, check out these 4 tips on how to choose a suitable one. It’s not so easy to decide as there are many choices out there. Basically wireless router is used to route the network traffic between your network and Internet. Hopefully these tips would help you to make good decision.

Check What Wireless Standard you Need

There are many wireless routers supporting different wireless standard, such as 802.11a, 802.11b, 802.11g and 802.11n (draft n), so which standard should you use?

The most popular and mature standard is 802.11g but the latest is 802.11n (draft n), however I would advise to choose the one with 802.11g standard if possible.

802.11g can support bandwidth up to 55Mbps in the 2.4GHz band. It’s compatible with 802.11b products because they both use the same radio frequency. That means 802.11g wireless router will be able to talk to 80.11b wireless adapter. The only problem of 802.11b/g is its interference with other electronic devices that utilize same 2.4GHz radio frequency and this will affect the wireless signal strength.

Then how about 802.11b? Since 802.11g is backward compatible with 802.11g, so I don’t recommend you to use 802.11b product. 802.11a wireless router is not so popular and normally used by business users, so you can forget about it.

As for the router with 802.11n (draft n) standard, it’s still new and the standard is yet to be finalized by IEEE. The expected speed is 10 times faster than 802.11g and the coverage is much wider. If you plan to buy it, be prepare to pay more as the price is expensive.

Compatibility with Other Wireless Devices

Think about the compatibility with wireless adapter, access point or other wireless devices when you choose the router. That’s no point you bought an 802.11g wireless router when other wireless devices are 802.11b aware only.

Always take into accounts of how do you plan to deploy the wireless network, what wireless devices you have and what others you plan to buy when choosing the wireless router.

Wireless Encryption Support

You must always enable encryption on your wireless router, so choose the router with at least WAP encryption. The best you can choose is the one with WPA2 encryption support. Having encryption in your wireless network would allow authorized users with correct encryption key to join the network. It would also avoid your network bandwidth from stealing by neighbor or strangers.

Don’t use WEP encryption on your router if you have better choices, this type of encryption is easily to be hacked by using hacking tool that freely available on Internet.

Other Security Features on Wireless Router

Look for the router that provides firewall feature! This will add an additional layer of protection to your network. If you manage to get the one with stateful inspection support, that would be the best. Stateful inspection firewall will inspect every state of the connections providing better capabilities to drop the malicious traffic.

Check also about the URL, IP and MAC address filtering features. These mentioned security features should be common nowadays, but just check about it to make sure the features are there.

That’s all for the tips, it’s time to go to get your wireless router. Have fun! :o)

If you are a part of the modern information age today, you would have noticed that everything these days is moving at a blistering pace. It wasn’t that many years ago that we were tethered to our walls if we wanted to talk to someone that wasn’t within earshot. These days you are hard-pressed to find a place that average everyday users like you or I would go where a mobile phone will not get coverage. If we indeed do happen to find such a place, we are outraged at the inconvenience. It is surreal to think that something that sounded like science-fiction such a short time ago is now so ingrained in our society today that we seemingly cannot live without it. Well brace yourself for Round Two, because Internet connectivity is about to come of age as well.

Wireless routers seemed to enter the market place without too much fanfare. This may have been in part due to their slightly less reliable nature in first incarnations, or the fact that people just couldn’t see the use for wireless connections in the home. Why have wireless connections when for years we have become used to the fact that if you have a computer in your house, there will be a phone line next to it? Now that we are on the move more and more, wireless connections are starting to make a lot of sense to the average Internet user.

To cope with our new thirst for data-on-the-go there is a new wave of ‘hotspots’ springing up. These are places where people can take wireless compatible computers and connect to the web with minimal fuss. Airports, hotels, and bus stations were the first logical places for this type of connection but they are now spreading to places wherever people use computers. People have even begun to list free hotspots at sites like http://www.wififreespot.com/. This is great if you are traveling across country and need to check your email or send photos back to loved ones.

The games-makers have also realized that this is a booming area. Nintendo have just partnered with McDonalds to start bringing consumers wireless gaming via the Nintendo Dual Screen (www.nintendo.com/systemsds) handheld console at selected restaurants across the country. When I connect wirelessly to other people in the world and race around a track in Mario Kart, there is barely time to reflect on how amazing this technology truly is.

There are also certain Internet service providers who now have begun to offer ‘unwired’ services to their customers. This type of connection requires no physical link to the end consumer. Traditionally you would have your wireless router plugged into your existing land-line connection and then you could connect your computer without the use of a cable. Now, the only requirement is that the consumer is based within the large hotspots that the service provider has created. No more hooking up to the phone line.

With all this data flowing freely through the air at ever increasing speeds it is hard not to get carried away thinking about what could actually be done with this sort of technology. Your DVD collection could be stored anywhere in your house and available on demand to any one of your displays, be it in the kitchen, lounge room, or bedroom. The same thing would apply for your music. You could even have a small chip stored in your shoe, clothing, or wallet that linked your personal ID to your play lists. As you moved from room to room in the house, your data could follow you. Ovens could have a direct stream of your recipes for easy access. The trusty alarm clock could wake you at any time with only the day’s News that you want to hear. There could even be an in-depth weather report from your closet as you get dressed. Removing the constraints of ‘where’ we can access information means that rather than slowing us down while we gather it, information can be fed to us as we need it.

As these hotspots grow you won’t even have to leave your data at home. Even the traditional act of sitting down and watching television could be tailored to your personal needs and streamed to you at times when you are able to watch it, such as bus trips or waiting at the dentist. Doing the shopping could be as easy as picking up an order that you mailed ahead during a lunch break. To some this all might sound like information overload and to an extent, you could be right. There is however an upside to packing more into the small, unutilized spaces of our day. If we can get small jobs done while we are commuting or waiting at the dentist, rather than having to go home, sit down, and log on, it frees up a larger chunk of time for us later to go out and enjoy life. Just don’t forget to turn your phone off so you won’t be interrupted while you do!
