With technology today, it’s easy to just set something up and let it go. That’s exactly the case with many computer users that have wireless modems in their homes. They leave the wireless network open not knowing what it could end up costing them in the long run.
Imagine sitting at your home and someone knocks on the door. You lazily go to the door knowing you aren’t expecting company and you ask who it is. A loud voice comes from the other side saying “this is the police”. After they speak with you, you realize that someone has been using your network to do some pretty bad things and they think that it’s you that is to blame. This is just a scenario that could happen if you don’t secure your network and some hacker just happens to connect to it.
Not securing your network and allowing others to use it is dangerous. But, even if they don’t do anything illegal they are still taking precious bandwidth that you pay for and could be slowing your internet down. Even without any knowledge on your part.
Fortunately there is a way to secure your wireless network and stop others from connecting to it and doing bad stuff. You can use WEP or Wired Equivalent Privacy. Some may incorrectly call WEP wireless encryption protocol but this is incorrect. WEP was created for wireless networks so users could secure their networks and not allow others to sniff or view traffic over these networks. In short, WEP will help protect your wireless network and keep it secure.
Most modern wireless modems whether they are ADSL or cable modems have WEP installed, however it usually isn’t enabled. To check whether WEP is enabled, you can take a wireless enabled laptop. If you can connect to the network without a password then WEP is probably not enabled. To enable you’ll need to log into the modem and change it. Calling your internet service provider can usually walk you through the process step by step. This is especially true if they issue the modems to their customers.
