Wrapping it Up

Remember that before you spend money to extend your Wi-Fi network, make sure that your router is placed properly and that interference isn't hindering your signal.

After that, consider making the upgrade to Wireless N, using powerline networking, or running cables.

Always keep these tips in mind:

  • Keep your networking gear up-to-date with new drivers for your adapters and firmware releases for your routers and access points.
  • Keep your network secure by at least using WPA-PSK/Personal with a strong passphrase—WPA2 is even better.
  • Best prices for gear are usually online—use comparison tools, such as Google Product Search.
