Change your default router admin username (if applicable) and password.

Ensure encryption is set to WPA2-PSK. Set encryption to AES if possible.

In the cases above, don't use "dictionary" words as passwords. Use combinations of upper case, lower case, numbers and other characters such as # < >, you get the concept? (This is not always possible.)

Turn off WPS.

Ensure your router firewall is active.

Turn off Guest Networks (if an option).

Ensure your router Firmware is up to date.

Use software firewalls on all your connected devices.

 

Other things to consider:

Don't broadcast your SSID.

Filter MAC addresses.

Switch off DHCP and use only allocated IP addresses.

 

If all that seems to be too much you can always just turn off Wi-Fi on your router! Smiley Happy

You were doing so well up to this point Smiley Wink 

Other things to consider:

Filter MAC addresses.

These three are myths that continue to be paraded.

  1. If the router's not broadcasting the SSID then the device that wants to connect has to.  Furthermore the SSID is broadcast as part of the association process before encryption is set up.  So hiding the SSID on the router doesn't really hide it.
  2. MAC address filtering is trivial to bypass.  All I need to do is monitor traffic to see which MAC's are talking with one another, and then spoof one of them.
  3. Again only stops a hacker from connecting via DHCP - if I can monitor the traffic I can find out which IP range clients are using and set up a static address myself.  Turning off DHCP inconveniences regular users rather than hackers.

So the main way of keeping people off the network is to make sure you are using a STRONG WPA2 password.

 

If all that seems to be too much you can always just turn off Wi-Fi on your router! Smiley Happy

Re: Wifi intruders

Fair comment on the last three suggestions, but to be fair I did note them separately, and it won't do any harm using one or all of them.

If somebody is going to the trouble of using traffic monitoring software I am aware these steps may be redundant and easily bypassed, but it may help to deter a casual hacker.

Re: Wifi intruders

If it's a casual hacker then the best measure is a strong wifi passphrase.  The last three measures cause more problems for legitimate users, compared to the challenge they provide to hackers.

Set a strong password, mine is the last 26 digits of Pi!

Slightly off topic - while a good password to be sure, if you've really managed to calculate the last 26 digits of an irrational number, then you must tell the maths world your secret, you'd make a fortune!! Smiley Very Happy PMSL
