Further security options
When setting up a router (wireless or otherwise) it is also a good idea to set the following options if possible:
- disallow admin access from the interwebs (e.g. LAN access only)
- disable telenet access
- change the default password for the admin account on the router. Some devices also allow you to change the user name, if they allow this do so.
- Use WPA, not WEP, and change the key to something long and complicated. Write this down and stick it somewhere safe, e.g. to the bottom of the router - if someone has physical access to the router then and obscure password is likely to be a moot point anyway.
- if possible, set all devices that will be attached to the router to have a static IP address, and disable DHCP on the device, if possible limit the range and number of IP addresses the router handles to those you have assigned.
Not all routers will necessarily support all of the above configuration options but in my experience, most will.
