Here's my situation:

  • Have a wireless/wired router. Wireless is disabled and they're currently using regular cables for internet.
  • My router has a password
  • I don't want people roaming around on my computer, so how do I secure it?



This is how it's setup:

  • Modem is plugged into router
  • My PC and their PCs are connected at the back of the router



I've looked under network settings and I've turned OFF network discovery and public folder sharing.

I turn off "file and printer sharing" too, but whenver I restart the computer, it automatically goes back to "ON" (only for file and printer sharing, not the others).


Anyone have any insight into this? Are people who are sharing the internet using cables able to fool around on my computer? And why is the file and printer sharing always turning back on?


I have an Asus RT-N12 router and Win 7.

Any help would be really appreciated smile.gif

You could disable network sharing on your computer. That might work but i have no idea how deep the block would go.

If the router has some form of guest network (would prob be wireless only) that is what i would use. lets them access the internet on a different network, so they cant get to your stuff.

*EDIT* from the ASUS homepage, it sounds like it does indeed support multiple networks. So setting up a simple wireless guest network (secured, naturally) should be no problem

Easy. Disable DHCP and set the private IP addresses to something very unusual, like in the 172.168.x.x address, with the default gateway something not obvious. Anybody plugging into your switch/router would be unable to guess the gateway address, and a network sniffer would be impractical for most to figure out what it is.

This network stuff is really over my head frown.gif


M3nta1, I am aware of doing a guest network, but I chose to disable Wireless on purpose so I don't get hacked by strangers from the outside, which ironically leaves me open to snooping/hacking by my guests.

I really don't know what to do.

I don't know how to do this, I'm such a noob.

Honestly, WPA2 is fairly resistant to hacking. Chose a strong password ( XKCD to the rescue! http://xkcd.com/936/ ) and use WPA 2 encryption and you should never have a problem. Then, you can just disable wireless when your guests leave and boom, back to being safer.

In terms of easiness
(1) Disable File Sharing and let guests use the "guest network'
(2) Use WPA2
(3) Use MAC filtering
(4) Turn off DHCP and use static IPs for all users , turn off SSID

anything from then on is generally overkill

edit: also make sure you use a long alphanumeric router password.
