![]() ![]() If you run NetStumbler while you're attached normally to your network, using WiFi, you'll experience the same instabilities as when when you run multiple WiFi client managers. NetStumbler binds to the WiFi adapter just like any other WiFi client.If you have a cordless phone, microwave oven, or nearby ham radio operator, NetStumbler will show those merely as "noise", as part of the signal to noise ratio for any WiFi network device. It does not work with every known WiFi adapter.Netstumbler, though free, and easy to use, has disadvantages. ![]() From a tree entry in the left column, you select a specific MAC address, and you can observe a running signal to noise graph for that network device. If you identify an interesting AP from the main list, you can find the MAC address for that AP. The display that you see immediately is the AP inventory, which enumerates each AP observed, and includes over a dozen very useful details about each. ![]() NetStumbler has two displays, both very useful. Netstumbler continuously scans the WiFi spectrum covered by your WiFi adapter, identifying each WiFi network device (whether access point / router, or client), and recording a dozen or so metrics about each network device found. Netstumbler makes a free, lightweight WiFi spectrum analyser from your computer and WiFi adapter of your choice. There are many tools to objectively analyse your WiFi network some are free, others cost good money. With a WiFi network, you have to go a level deeper than Internet Protocol (sometimes, IP may not even be relevant). When your Ethernet network stops working, you can start with a simple IP scan of the subnet. With all of that in mind, you need to evaluate your WiFi environment objectively, both before setting up a WiFi LAN, and after. All the planning you do is useless when your neighbours install a WiFi LAN next door. And sometimes, even without you making any changes, you'll have problems. Some of them you can correct, others you can't. There are many reasons why you won't get the expected bandwidth from any WiFi network. Installing a WiFi network takes careful preparation. But WiFi is not an effortless replacement for Ethernet. WiFi, or Wireless networking, can provide relief from the mass of cables. When you setup a network of computers, in your home or small office, a mass of Ethernet cables running everywhere can be a problem. ![]()
