Also as some added protection you can set the router only to except connections from specified MAC address's. i.e. your pc's and devices.
ipconfig /all will show you this from a command prompt.
lastly once you are all set up and devices connected , go back to your router and hide your SSID from view.
There is much more that can be done to stealth your router, but if you do the above you should be pretty much bullet proof.
Also a good idea to change your lan ip address from , say 192.168.1.1 to something else , for example 10.10.90.1
COPIED AND PASTED!
Thanks Bro! That's my main concern, and this helps a lot.
