This is a follow-up to the last article about having multiple computers. One of the great things about the new home networks is that they are inexpensive. Additionally, you don’t have to hire a network specialist to keep it running (which you almost needed to do until about 5 years ago). Today’s home networks are reasonably simple to set up, especially if all your computers have Windows 7.
All you really need is a router (usually with wireless capability) and the cabling to connect your computers to it, or wireless network adapters to communicate with the router. There are a few things you should know before jumping into this option.
Initial design and placement of network resources is important. You must decide where you are going to run cable and if it will be hidden in the walls. Running cable across the floor is a good way to get your wife angry. If you are using wireless, you need to remember that walls and especially metal will reduce how far the signal will travel and how strong the signal will be. ?A signal that must travel through a wall at an angle is reduced drastically, as compared to one travelling at right angles through the wall.
Types of wireless are designated by letter. N series wireless is stronger, faster and travels farther than G series. B and A series are no longer used and are weak and slow. Within these categories there are good, better and best types. The store display will usually indicate which is the best value – but you do get what you pay for as the faster, more powerful routers cost more. Also remember that if you get an N router, you may want to upgrade the wireless adapter in your computer to take advantage of it.
If you are using wireless, you should definitely encrypt your signal so unauthorized persons can’t “hack” into your network. It used to be if someone next door used your wireless internet, it would just slow your performance. Lately there have been instances where child pornographers or identity thieves will drive up to someone’s house, hack their internet and do their business through your router. Since those transactions are tracked by the government, a lot of innocent people have been investigated and their computers temporarily confiscated until their innocence was proven. Please encrypt your signal or have a professional do it if you don’t know how.
Finally, remember that, with a network, all of your computers can share data as well as all of your printers, scanners, and most other peripheral devices. This can save you a lot of money and space.
Even though the new networks are much easier to set up and maintain than the old ones, if you have doubts or concerns, contact a professional who can ensure you are set up optimally and securely. Remember to be safe – and always have a backup of anything important.
