Customer Network Support Page

Computer Networks have become a way of life as of late. We have them at work, often at home too, and certainly every place we visit any more. How is it that linking computers together became such an important tool in our society?

Networks

To begin with, we have to remember that we're in the 'Information Age.' Computers create, control, and disseminate information much faster than we can with paper and a pen. So what happens, when you have files on your computer that I need to see or change in mine? The only options are to either save the file from your machine to removable meda (CD Rom, USB Drive, or Floppy) then transport it to the other computer, or else have them in a Network to share the files. The latter is so much less time consuming in a busy office!

What happens when the Network goes down though? Of course this never happens at a good time. It happens when the work is (over)due or the customer is waiting for a printout. Yes, fortunately there are things that you can do before calling San Diego PC.

Without getting too technical however, you need to know a few things: Each computer on the Network has an IP address. This address is simply a number that identifies it on the Network, just as your house's address identifies your home on the street.

The next thing is the infrastructure of the Network itself. The most common cabling between the computers will be 'Cat5' cabling, which plugs in to the back of the PC just the same way that a telephone cord plugs into a phone. This cable may simply go between a pair of computers, or more commonly it will be plugged in to a router at the other end. This is the device that links all of the computers together, using the Cat5 cable. It will be plugged into the wall for power, and a a cable will be stretched between it and each computer that it provides signal to.

When the Network fails, the first thing to do is think if anything in the office has been moved that would have disrupted the cables or the power to the router. Make sure that all of the lights on the front of the router are lit, that are usually on.

If all of the cables are connected and the router is indeed, plugged in, then we need to dig deeper. You can try unplugging the router for 15 to 30 seconds, then retry the Network at the computers. If that's not convenient to so, you can tell the computer that you are using to get another IP address from the router.

This is done by opening a DOS window: Click on your START menu, then RUN. Type the word 'CMD' without the quotes and press ENTER. In the DOS box that appears, type 'IPCONFIG /RELEASE.' The computer should confirm at this point, that the address that was in use has been released. What follows is the same IPCONFIG command, followed this time, by the word 'RENEW.' At this time you will see the new address that has been assigned by the router for the computer to use.

If these steps fail, then the problem is not one that is presenting itself too easily, and you should call San Diego PC for your next step.

The Solar Attic Fan- Cooling From The Top Down

Even a few days of unexpectedly hot weather, given the soaring costs of energy, can send even the best-planned home energy budget into a tailspin. Homes with air conditioning units have barely livable interiors, and those without them are simply unlivable. But there is a ray of hope, in the form of a solar attic fan.

Attics, especially in under-insulated homes, can be the equivalent of having a rooftop furnace going full blast during the summer months, and one way to prevent attic heat buildup is to install an attic fan and transport the warm attic air to the outdoors where it belongs. But the problem of rising energy costs once again raises its ugly head in any discussion of attic fans.

Cost Savings From A Solar Attic Fan

Traditional attic fans can running 24/7 during a heat wave can significantly increase your home cooling bills, but instead of letting that prospect keep you from installing one why not look into a solar attic fan? A solar attic fan will work like a traditional electrically powered one, but instead of drawing expensive power from you local electric utility, will draw it from the biggest and cheapest power provider known to man--the Sun.

Once youve purchased and installed your solar attic fan and its solar energy collecting panels, you will be cooling your attic for free. Not only that; as the solar attic fan reduces the temperature of your attic, you air conditioning will have much less work to do in keeping your homes lower portions comfortable. So your attic cooling will cost nothing, and your overall home cooling bills will decrease as well. You should have you solar attic fan paid for in just a couple of summers!

Other Advantages Of Having A Solar Attic fan

Even in cooler weather, a solar attic fan can be one of you best home maintenance tools. Attics are notorious for collecting moisture from the kitchen and bathrooms beneath, and a persistently damp attic can lead to all sorts of structural problems like mildew, mold, and wood rot. Any of those conditions may have an equally negative effect on your homes occupants as well, and the improved ventilation from a solar attic fan will go a long way towards preventing them.

Your solar attic fan can operate even during the night, when the sun isnt shining, because its solar panels will store whatever solar energy the fan does not consume during the day and provide free power from sundown to sunup!
