Sometimes home network problemsare as easy to fix as plugging in a cord, yet “check your cords” is almost all the advice you’ll get from overworked help desk operators. Sometimes you get onto a help desk operator that wants to take you through every simple step, even the ones you have already performed. The average computer user gets very frustrated with troubleshooting methods used over the phone when trying to diagnose their home network problems. If you do not have time to sit there and listen to an hours worth of pre-recorded troubleshooting tips will give you a few ideas to try when having home network problems. If you have a wireless connection you should also see 5 Threats To Your Home Wireless Connection.

Here are 5 common home network problems:

These common  Home Network Problems may be responsible for the Internet not working as you expect. We also have an article about 5 uncommon home network problems.

Common Home Network Problems #1: Router Failure

Although computer hardware is increasingly reliable these days, I find that routers are one of the devices most likely to fail when having home network problems. Unlike most computers, routers stay on all of the time and perform millions of complicated electrical connections every second, causing them to wear down faster than most other hardware.

All modern routers run a stripped down operating system (usually Linux or NetBSD) which can suffer from its own errors besides the possible  home network problems that can occur. Here are three steps to follow to diagnose and possibly repair your router:

1. Unplug the router, count to three, and plug it back in to the wall. Routers often suffer from micro-blackouts present in home power supply (also called brownouts) which can screw up the operating system on the router. Unplugging the router and plugging it back in will force the operating system to reboot.
2. Most routers start with all of their lights on and then turn off the lights for any unused network ports. If the lights all come on and stay on, it usually indicates the operating system failed during boot. If your device is under warranty, contact the manufacturer or your service provider. If you need to repair this problem yourself, follow the instructions in your router’s manual for resetting the software; if that doesn’t work, you need to buy a new router.
3. If none of the lights on your router light up, make sure it’s plugged into a working electrical socket and that you have at least one computer plugged into it. If it still doesn’t work, then the router is dead and probably not worth repairing.

Common Home Network Problems #2: Wireless Interference

In the United States, the Federal Communications Commission (FCC) never gave computer companies permission to create wireless devices. The companies just started doing it using a special part of the wireless spectrum the FCC calls unlicensed.

Anyone can run a device on this part of the wireless spectrum for any purpose (except for the purpose of deliberately jamming other people’s connections). Because the unlicensed part of the spectrum is free, many companies besides computer companies use it to transmit wireless communications for their devices. Devices using the unlicensed spectrum include cordless telephones, bluetooth devices, wireless speakers, small FM radio transmitters used with iPods, walkie-talkies, and baby monitors.

People with an FCC-approved amateur radio license, such as your author, can broadcast at high power on the unlicensed frequency.

All of these other signals can significantly reduce the quality of your wireless Internet connection and cause network problems. The only way to deal with the annoying error is to find the offending device and try to turn it off or move it away from your laptop or router. Here are some steps you can use to find the offending device:

If you have a walkie-talkie or a baby monitor, walk around with the hand-held part until you hear a lot of noise. Keep trying to get closer to the noise until you find the offending device.

If all you have is a laptop and wireless router, you need special software. For Windows, I suggest the free inSSIDer 2 from metageek.net. Install it, open up its Time Graph, and start walking around where the interference is greatest until you find the offending device.

If the offending device belongs to your neighbor, there’s nothing you can do legally (unless you can prove your neighbor is using too much power or is purposely trying to block your signals). However, I find that an amicable solution can usually be reached: ask your neighbor to move the device to end of his or her house which is furthest from your house; then, move your router to the end of your house furthest from your neighbor. In most cases, this should be enough distance to eliminate the interference and give you full-speed wireless networking.

The problem can also stem from having two wireless routers in the same house.

Common Home Network Problems #3: Too Much Upload

Everyone knows that downloading a big file makes downloading any other files or Web pages run slow, but did you know that uploading a file can make downloading run slow too?

The most common networking protocol on the Internet is the Transmission Control Protocol (TCP). TCP says that your computer must send an ACK packet (for acknowledgment) to the computer it’s downloading from every time it gets a big packet of downloaded data. This prevents the other computer from sending data to your computer after you cancel a download.

If your network is using all of its available upload bandwidth, your computer can’t send its ACK packets, so other computers stop sending data to your computer.

If your Internet connection is running slow, check the computers on your network to see if any are uploading a lot of data. Here are some applications that often hog the upload:

• Filesharing applications like BitTorrent
• 3D multi-player games like World of Warcraft
• Voice over IP (VOIP) Internet phones like Skype. See making conference calls with Skype.
• File uploads like uploading your pictures to Shutterfly or sharing files with family using Dropbox or uploading a video to YouTube

Common Home Network Problems #4: Bad Network Drivers

Microsoft Windows ships with over 100 different network drivers, which is a great convenience–you can usually just insert a new wired or wireless network card and start surfing the Internet. The only problem is that Windows only gets major updates once a year, so any drivers it ships with are usually out of date. This can cause home network problems as the driver will be out of date very quickly.

If you just purchased a new network card and it isn’t performing as well as you expect, you can try a very easy solution: install the driver that comes with the card (or download the driver from the card manufacturer’s website).

Common Home Network Problems #5: Zealous Firewall Rules

Firewalls provide essential security to Windows computers, but they can be a huge hassle when you try to share resources on your computer with other computers on your network and around the world. This is one of the most common home network problems that can interfere with your internet connection.

If someone is trying to connect to your computer and they get a “Connection Denied” error or a strange error, check your firewall rules to see if you’re blocking the other computer. If you are, you need to make an exception–but be careful, too broad an exception can open your computer to attacks from hackers.

The best exception only lets a specific computer connect to a specific port. You can figure out the port by searching Google for the name of the service you’re attempting to share. For example, a search for “windows printer port” brings up a Microsoft Technet article indicating the printer port is 9100.

To only allow a specific computer to connect, you need to know its IP address. If the computer is on the same network as you, open the start menu on that computer, click the Run… icon, type in cmd, type ipconfig on the command line that appears, and write down the IP address. Use that IP address in the exception you create to your firewall rules.

If the computer is running on the Internet, open a Web browser on the other computer and go to whatsmyip.org. Write down the IP address they give you and use it to create the exception to your firewall rules that fixes the problem with your home network so the other computer can connect.

How to connect two computers to a broadband modem

If you have a broadband modem or one that is supplied from your internet service provider (ISP) you can most probablyconnect two computers to it without needing a router. If you look at the picture of my modem below, it has a USB (blue) and a ETHERNET (yellow) port. Of course there are many other ways to connect two computers together to share files or an internet connection, however this article is about connecting two computers to one modem.

My service provider, Telstra Australia, supplied this modem to me. It came with an installation disc, which you should use to connect to the modem through the USB.

Now if you do not have a router, but have a similar modem to the one shown, you can connect two computers off the one broadband modem and thus both accessing the internet.

One computer can connect through the USB port and the other through the Ethernet.

A USB cable and and Ethernet cable come with the modem, however to connect the second computer you may need to buy a longer Ethernet cable. Get a blue cable.. NOT yellow or red. The blue one is a CROSSOVER cable, the others will be PATCH cables. They have the same connections on them but do entirely different jobs. (this colour coding applies in Australia, I don’t know about other countries.)

How to connect two computers to one broadband modem?

In this tutorial I will show you how to connect two computers to the same broadband modem.

What do you need to connect two computers?

1. You will need two computers to connect to one modem.
2. You will need an ethernet cable and a USB cable.
3. You will need a modem similar to the one pictured above.
4. You will need an internet connection.
5. You will need an installation CD to install through USB connection.

To connect a computer to a broadband modem through USB, it is recommended that you use the installation cd. It will ask you to choose how you want to connect and you select USB. Make sure you know your user name and password for your internet service provider.

To connect the second computer to the same modem but through the Ethernet, just plug it in…It usually works straight away. If it does not, use the installation cd, but choose to connect with Ethernet.

Notes on how to connect two computers:

• If you do not have an installation cd, phone your internet service provider and they will send one to you.
• See 3 other ways to connect two computers together.
• If you run into any problems, phone your internet service provider and they will help. It is perfectly OK to connect two computers to a broadband modem.

What is a virus and how does it get onto my computer?

The people that develop these viruses are constantly finding new ways to infiltrate your computer. When one door shuts, another one opens for them. However the most common ways to get a virus on your computer is through the internet. You might download a file that contains a virus, or maybe you might open an email that has one attached to it. Sometimes even visiting a bad website can infect your computer. The worst one of all, however, is when people download illegal cracked software. This software has usually been taken apart and repackaged with a few extras attached. Maybe you download music or videos from the internet. How do you know you are actually downloading the file you intended to. The file may be named to deceive you, and once you open it you will release the virus.

Another common way to get a virus is to see software appear on your screen that is posing as an antivirus program. The minute you press the cross button to close the program or even the scan button, because it is telling you to scan for viruses, you are immediately infected by this virus. If you see a program come up on your screen that you know you did not install, the best way to shut it down is to open up task manager and end the process.

How do I know if I have a virus or not?

If your computer has been infected with a virus you will quickly see odd signs that it exists. Weird things start happening that you cannot explain. Files might move around, odd error messages may appear, programs might start to fail. For example if your virus scanner program stops working then it could have been disabled by a virus. With all this action taking place in the background your computer will also start to run slow and seem like it is busy all the time.

When browsing the internet you might find that you will not able to visits the pages that you choose. You will be redirected to different websites. You computer might also be sending emails to everyone in your contact list without you knowing.

What can a virus do to my computer hardware components?

People think that a virus simply attacks the file systems of your computer, however this is not true. Some viruses are designed to damaged computer hardware components until they are ruined completely.

Many people will argue that a virus only infects software, however all hardware is controlled by various types of software. Infact the entire computer is controlled by BIOS which is software. BIOS controls the temperature of the motherboard. What if a viruses only purpose was to change the temperature control on your motherboard. The motherboard would overheat and fry itself.

In the old days viruses used to be developed to set the read speed of a floppy disk drive to speeds beyond its capability. The Floppy disk drive would overheat and fry from being overworked. Now days Windows Vista has a service called Superfetch that searches your hard drive, finds out what you use the most, and makes it available for you.. If you made a virus to control Superfetch, we could have a serious problem. Most Vista users already have Superfetch disabled on their computer. A virus could enable it, tell it all files are important, keep it searching non stop, and fry your hard drive that way. Now I can here someone saying “yeah right, not with all the security we have around today”. Well you should never underestimate these guys who develop viruses. They can work around anything.

What should I do if I get a virus?

If you suspect that your computer has a virus, scan your computer asap with an antivirus program. If you do not have one or yours is not working, download another one, or get a free scan using the free online virus scanners.

Here is a list of free online virus scanners.

Symantec Security Check, McAfee FreeScan, Panda ActiveScan, Trend Micro,Kaspersky lab, bitdefender, and there are so many more. There is no guarantee that these free scanners will cure your computer but they might just confirm the fact that you actually have a virus.

If you find viruses but cannot remove them you will need to take your computer to a professional before you lose everything. Another option is to format your computer which means you loose all the files on it and re-install a fresh copy of the operating system. You can backup your files first, but please be aware that they might be infected with a virus also.

If you have scanned your computer, found viruses, and successfully deleted them, then now is the time to buy a decent program that will stop this from happening again. See my review of the best Virus Removal Software.

Do not continue to use the computer without taking action because the longer you leave it the further the virus can spread.

What is a virus? What file types commonly contain viruses?

Lets face it, downloading is a dangerous business, especially when you have important files stored on your computer. Any file you download can contain a virus. My rule for downloading is to ask myself “Do I know and trust this website I am about to download from?”

Here are a few examples of common files that could contain viruses:

EXE FILE: If you download a program or anything that requires an install file then it will be an .exe file. When you press on it to install to your computer you could be releasing a virus.

ZIP FILE: People download zip files from the internet that contain any other file type and you will not see it’s contents until you open it. A zip file might have an exe file in it.

SCR FILE: Free screensavers for your computer. They always have something bad in them. Sometimes adware or viruses.

DOC FILE: A Microsoft word document can contain macros and small scripts that are viruses.

If you haven’t got antivirus software installed on your computer you can try Avast. It also takes care of spyware, malware, etc and it is fantastic!  Take advantage of avast! try before you buy policy. avast! offer most of their products on a trial basis for 60 days. Click here

Notes on what is a virus:

• There is a lot of confusion about actually “what is a virus” because there are so many different types of viruses out there.
• Most, if not all websites on the Internet agree that a virus is a small piece of software that invade your computer.

I hope you are not still asking “what is a virus” as this can be a very dangerous question

Intel Corporation (NASDAQ: INTC; SEHK: 4335; Euronext: INCO) is an American global technology company and the world's largest semiconductor chip maker, based on revenue.^[5]It is the inventor of the x86 series of microprocessors, the processors found in most personal computers. Intel was founded on July 18, 1968, as Integrated Electronics Corporation (though a common misconception is that "Intel" is from the word intelligence) and is based in Santa Clara, California, USA. Intel also makes motherboard chipsets, network interface controllersand integrated circuits, flash memory, graphic chips, embedded processors and other devices related to communications and computing. Founded by semiconductor pioneers Robert Noyce and Gordon Moore and widely associated with the executive leadership and vision ofAndrew Grove, Intel combines advanced chip design capability with a leading-edge manufacturing capability. Originally known primarily to engineers and technologists, Intel's "Intel Inside" advertising campaign of the 1990s made it and its Pentium processor household names.
Intel was an early developer of SRAM and DRAM memory chips, and this represented the majority of its business until 1981. While Intel created the first commercial microprocessor chip in 1971, it was not until the success of the personal computer (PC) that this became their primary business. During the 1990s, Intel invested heavily in new microprocessor designs fostering the rapid growth of the computer industry. During this period Intel became the dominant supplier of microprocessors for PCs, and was known for aggressive and sometimes controversial tactics in defense of its market position, particularly against AMD, as well as a struggle with Microsoft for control over the direction of the PC industry.^[6][7] The 2010 rankings of the world's 100 most powerful brands published by Millward Brown Optimor showed the company's brand value at number 48.^[8]
Intel has also begun research in electrical transmission and generation.^[9][10]
