Tech Wiz on simple network security…

Connections, both Bluetooth and wifi are interesting. Look, the most important thing you as a person can do is understand what the two mean. Wi-Fi or Wireless Networks represent a section of the bandwidth available from a router. WIFI is strong but decreases the more walls it encounters. Walls tend to have wire, power and other things that interfere with WIFI signals. Bluetooth also has issues with walls. But unlike WIFI it is a much smaller radius than WIFI. Bluetooth, named for the Norweigan Viking Lord, (Harold Bluetooth) has a range of around 30 feet. WIFI can go as far as 300 feet. Hackers can bluejack your Bluetooth device, and they can hack your WIFI access point.

Let’s talk reality and let’s talk about what you need security wise and bandwidth wise going forward:

  1. Equal upload and download speeds. Remember your home router only has a small amount of RAM. You don’t care about that except that if your uploads aren’t equal to your downloads, you end up caching data on the router. That cache fills both upload and downloads. It makes your router less responsive. The more you cache, the more issues you will have over time.
  2. Bluetooth devices suck the battery, but they provide some additional valuable services (headsets, speakers) so balance that carefully.
  3. Bluetooth and WIFI don’t compete for bandwidth.
  4. WIFI bandwidth decreases the further from your network you get. Around 300 feet it begins to fade. That said, 300 feet is most likely beyond the edges of your yard.

The reality of the connections is you have to pay attention! I highly recommend the Fing Box. Fing Box is an easy to use internet security device for your home. There are three easy to follow the rules for your home network that will help you be safer. These rules won’t guarantee safety, that requires a lot more hardware and a lot more time.

  1. Walk the edge of your WIFI and know where your network ends.
  2. Know (use Fing Box or other tools) what your network does when you are gone, and when you are home.
  3. Make sure you have a notification system when a new computer joins your network.

Just those three simple security rules will help you.

  • Do you know where you home WIFI network ends?

    • Yes
    • No
  • Do you leave your bluetooth on all the time?

    • Yes
    • No
  • Do you avoid free WIFI connections?

    • Yes

  • Do you ever check how much capacity your home network has?

    • Yes
