I asked this question here :
And I would like to know more info about the last reply with regards to these things :
3.) if wireless, consider changing he SSID and disabling SSID broadcasting
4.) if wireless, consider limiting access to certain MAC address
5.) if wireless, consider using WEP or WPA.
6.) make sure "manage remotely" is NOT turned on.
7.) use something besides the default network of 192.168.1.0/24 network. Anything 192.168 or 172.16 is fine.
8.) check for new firmware upgrades
9.) consider other firmware if you need more - such as available at http://www.linksysinfo.org
10.) change the SNMP string, and turn it off if you don't need SNMP (depends on hardware and firmware).
If you could please ellaborate on the above things and how to go about doing them , even if you just post URL's that give me a rough idea on how to go abouts doing each of the above. I am also going to post another question just so you are aware :)
