Pretty feature loaded, don’t you think? As illustrated by the above screenshot, the above window is all that you get for NetAdapter’s user interface, but it’s quite full of options nevertheless. Roughly, the user interface can be considered as divided into two vertical panes. The left pane consists of a whole lot of button based troubleshooting and repair sub-options. Each of these accomplish a single distinct task and have a checkmark before them. You can either run these diagnostic/repair options individually, or select them via checkboxes to run multiple of these at the same time. There’s also an Advanced Repair option, which requires a system restart. Here’s a brief listing of what these options let you do:

  • Release and Renew DHCP addresses, Clear IP settings and Host file.
  • Flush DNS Cache, Clear Routing tables and Reload NetBIOS.
  • Enable/Disable LAN and Wireless Network Adapters, and clear SSL states.
  • Reset Internet access and privacy options and rollback Network service settings to default.

Then there’s the right pane, which essentially just consists of general network information such as your IP and MAC addresses, Default Gateway, Subnet Mask and things like that. It also lets you spoof your MAC address. In addition to that, it also a real-time refreshed listing of the system diagnostic activities (with date and time stamps), as well as the total data sent and received.
