Membuat HotSpot Area

Anda belum merasa enjoy dengan koneksi internet Anda? Alias terbelenggu oleh koneksi internet dengan jaringan kabel yang harus statis di satu tempat? Jika demikian yang Anda alami, pastikan membaca artikel ini untuk memperoleh beberapa alternatif, 1. Berpindah memakai jaringan 3G dari berbagai macam penyedia layanan 3G (Indosat, Telkomsel, dll), 2. Membuat jaringan wireless di rumah Anda (HotSpot Area).

Jika Anda harus berpindah dari layanan ADSL (speedy) ke layanan 3G yang disediakan oleh provider GSM maupun CDMA tentuah Anda memerlukan beberapa alat tambahan yang notabene relatif mahal. Minimal Anda harus membeli sebuah modem 3G lagi atau membeli handphone 3G, Haruskah Anda menghabiskan uang hanya untuk mendapatkan kenyamanan berinternet baik browsing maupun surfing dengan cara ini? Apakah permasalahan akan selesai dengan solusi ini? Tentulah tidak semudah itu, karena koneksi 3G juga dipengaruhi oleh lokasi tempat tinggal Anda. Dalam hal ini Anda yang berlokasi di daerah pinggiran alias tidak tercover oleh sinyal 3G (daerah yang jauh dari layanan 3G) tentulah hanya akan memperoleh layanan koneksi internet via GPRS, yang tentunya tidak secepat layanan 3G.

Anda punya solusinya? Mungkin itu pertanyaan yang akan Anda lontarkan kepada penulis. Janganlah berputus asa sobat, karena solusi kedua akan segera penulis sampaikan.

Mungkin Anda pernah mendengar tentang hotspot area? Hotspot merupakan area yang dapat digunakan untuk mengakses jaringan melalui WLAN (wireless LAN), termasuk juga internet. Selain itu yang perlu Anda ketahui adalah IEEE (institute of Electronics and Electronics Engineers) standart, yaitu lembaga yang melakukan standarisasi transmisi elektronik sedunia. Lembaga tersebut telah menetapkan standar yang dapat Anda baca di IT Today's (http://hardsoftwareinfo.blogspot.com).

Persyaratan yang harus dipenuhi untuk membuat Hotspot area, syarat pertama Anda harus punya koneksi internet (dalam artikel ini kita membahas koneksi dengan speedy). Apabila kita mendaftar sebagai anggota speedy tentulah kita telah memiliki modem ADSL baik dengan cara membeli sendiri ataupun paket dari telkom. Syarat yang kedua kita harus memiliki Wireless Router yang harganya berkisar antara 440.000-850.000, router ini berfungsi sebagai pembagi koneksi internet (internet sharing connection) secara wireless (tanpa kabel). Cara koneksinya cukup mudah:

1. Koneksikan kabel telepon kita ke modem ADSL kita,

2. Sambungkan Modem ADSL kita ke Wireless Router dengan kabel jaringan/LAN (biasanya kabel merk Belden) yang telah dipasangi conector RJ-45 di kedua sisinya,

3. Hubungkan Wireless Router dengan komputer kabel LAN,

4. Setting Wireless Router Anda melalui komputer yang telah terhubung secara wired LAN (dengan kabel).

Untuk pengaturan wireless route merk Linksys dan Belkin secara detail dapat Anda peroleh di buku manual Linksys dan Belkin. Selamat menikmat Hotspot area di rumah Anda, semoga bermanfaat.

Langkah Pembersihan Head Printer HP?LEXMARK/EPSON/CANON

CARA MEMBERSIHKAN HEAD HP/LEXMARK

1. Siapkan satu unit wadah plastik lalu tuangkan cairan pembersih head (ex: BP-PC100) pada wadah secukupnya +/- 3 mm dari dasar print head. Rendam print head selama 20 menit.

2. Pompa dengan udara secara perlahan pada lubang nozzle/udara pada tiap lubang head HP/LEXMARK sesuai gambar, lalu lihat apakah tinta atau gelembung udara telah keluar pada dasar head. Bila tinta telah keluar maka head sudah lancar, jika belum ulangi langkah no. 1 di atas. NB: Cara ini hanya dilakukan bila head buntu total, tapi head harus terendam pada cairan pembersih head.

3. Angkat print head dan tempelkan pada tissue berulang kali, lihat apakah tinta sudah keluar dengan lancar pada tissue tersebut, bila belum rendam kembali head pada cairan pembersih head sebentar lalu tempelkan lagi pada tissue hingga tinta keluar merata pada tissue tersebut lalu pasang pada cartridge pada printer & jalankan cleaning dengan printer software, cetak dengan mode high/best quality lalu kembalikan pada posisi normal quality.

4. Bila head HP/LEXMARK tidak memiliki lubang udara maka lakukan penyedotan tinta melalui print nozzle head/nozzle plat. Penekanan suntikan karet pada nozzle cetak jangan terlalu keras karena akan merusak nozzle cetak head. Sedot sampai tinta keluar dan test pada tissue.

Installation of Memory

http://keluargarahmadi.blogspot.com

Caution:

Before installing the memory modules, please comply with the following conditions:

1. Please make sure that the memory used is supported by the motherboard. It is recommended that memory of similar capacity, specifications and brand be used.
2. Before installing or removing memory modules, please make sure that the computer power is switched off to prevent hardware damage.
3. Memory modules have foolproof insertion design. A memory module can be installed in only one direction. If you are unable to insert the module, please switch the direction.

The motherboard supports DDRII memory modules, whereby BIOS will automatically detect memory capacity and specifications. Memory modules are designed so that they can be inserted only in one direction. The memory capacity used can differ with each slot.

Step 1, The DIMM socket has a notch, so the DIMM memory module can only fit in one direction. Insert the DIMM memory module vertical into the DIMM socket. Then push it down.

Step 2, Close the plastic clip at both edges of the DIMM sockets to lock the DIMM module. Reverse the installation steps when you wish to remove the DIMM module. Dual channel Memory Configuration

For example: GA-945P-S3 supports the Dual Channel Technology. After operating the Dual Channel Technology, the bandwidth of the memory bus will double. The GA-945P-S3 includes 4 DIMM sockets, and each Channel has two DIMM sockets as following:

1. Channel 0 : DDRII1, DDRII2

2. Channel 1 : DDRII3, DDRII4

If you want to operate the Dual Channel Technology, please note the following explanations due to the limitation of intel chipset specifications.

1. Dual Channel mode will not be enable if only one DDRII memory module is installTo enable Dual Channel mode with two or four memory modules (It is recommended that memory of the same capacity, brand, size, chips, and speed be used), you must install them into DIMM sockets of the same color.

The following is a Dual Channel Memory configuration table:

Description	DDRII1	DDRII2	DDRII3	DDRII4
2 memory modules	DS/SS	x	DS/SS	x
	x	DS/SS	x	DS/SS
4 memory modules	DS/SS	DS/SS	DS/SS	DS/SS

(DS: Double Side, SS: Single Side, X: Empty)

Computer Hardware Conflicts (By Chris Paxton)

Our computers have many different parts inside them that all need to work together. It is imperative that they run concurrently with no problems. When we take apart a computer we are left with many individual components. These components we find are graphics cards, RAM, processor, cooling fans, power units, hard drives, CD drives, wireless cards, special media card readers, sound cards, battery packs, that are all connected to the mother board. If one of these parts doesn't like the other it can cause major errors for your computer and how your computer may run. It could even result in your computer running slower than normal.

For example, in one of our company's computer that was built by us we had a graphics card that did not like the mother board connection for some reason. Unfortunately we did not know this at the time and it took us about two weeks to figure it out. This caused the graphics to constantly have a delay. Sometimes the delay was tolerable but other times the delay was so bad that you would move the mouse and the pointer would start to move on the screen 5 seconds after we moved the mouse. We would shut down the computer properly and restart and most of the time it ran perfect again like it had no problem at all but later on it started to act up again. We updated all the drivers, talked to the people that make the graphics card, changed out the monitor thinking it was that. After working out all the bugs that naturally come with a self-built computer we found a guy that worked for the company that produced the mother board that we were using and even though they claimed that our graphics card was compatible he admitted obviously it wasn't. He swapped out our graphics card for free and our computer has never been stronger.

If you build your own computer you are taking on the risk of having hardware conflicts. The good part of this story is that in today's world many of the companies that make these components are doing their best to make sure everything is universal. People are working day in and day out to make sure the hardware/components of your computer are programmable so that they can make everything compatible with just a simple software adjustment or driver upgrade. If you have a conflict among your hardware you can still get the maximum performance out of the components you have picked. A simple driver update can do the trick and keep you away from having a slow computer or the frustrating process of trying to find out what the problem is.

Help Slow Computer can help with any questions that you may have or would like to bring up. Speeding Up Your Computer is something that you can do on your own and we can help.

The High Cost of Inkjet Printer Cartridges (Peter Stroud)

Inkjet printers offer a print technology that offers professional printing for the home and small business user at a minimal cost, often for the cost of one or two hundred dollars. Unfortunately the exorbitant cost of the replacement ink cartridges soon brings the dreamers of d.i.y. high quality printing (which lends itself to the concept of savings) back to earth.

A set of ink cartridges often cost more than a new printer.

In fact at one stage in the evolution of inkjet printers, it was cheaper to buy a new Canon BJC210 printer which contained both a black and color cartridge, than it was to buy a new black, and a new color cartridge for the same printer from a retailer! It is obvious from this example to work out where the profit for the printer / cartridge manufacturer was.

With the high cost of replacement inkjet cartridges there are many developments in the market for reducing the cost of printing with desktop inkjet printers.

Options included:

* compatible inkjet cartridges
* refilling inkjet cartridges
* continuous inkjet delivery systems

Each of these alternatives offers ways to reduce the high cost of manufacturers inkjet cartridges while still producing quality inkjet prints.

Savings varied with the method employed and the type of cartridge involved.

Savings from as little as 10-20% are offered by some compatible cartridges. Other "simple" cartridges which contain very little technology often offer savings around 60%.

Refilling inkjet cartridges often saves of around 50% where the end user employs the services of a professional refiller, while refilling a cartridge as end user gives greater savings (and sometimes greater frustration).

The greatest saving can be achieved with many inkjet printers is by using one of the alternative continuous ink supply systems. Due to the investment of the ink supply system, a reasonable volume of printing is required to return the greater savings.

Continuous ink supply systems can offer savings of over 90%.

Peter Stroud has had a hands on role with the cartridge remanufacturing industry over a period of 10 years. The website continuous inkjet ink system references many of the ink systems and associated suppliers of continuous ink system components.

Epson printers have traditionally been a favourite of continuous ink system suppliers epson stylus photo 1400.
