I wanna protect myself against bad ppl who use sniffers with promiscuous mode ON. i searched alot about that but with no hope. i asked my ISP to install intrusion detection programs like SNORT to detect those ppl, but he said that he cant for some reasons. is there away that i can prevent, not detect only, those ppl from using this thing to gather private information from me.

Use a good FIREWALL, preferably a hardware NAT and SPI firewall in your router. You could have a second layer of defence by using a software firewall such as ZoneAlarm, which can also prompt you to Approve all outbound connections from your computer to the Internet.

By implementing a firewall, you restrict the traffic which can connect into your networkand the traffic which can connect out, thus making it very difficult for someone to access your computer and gather information about you.

I guess you are talking about an broadband connection to your wireless router, right?

if this is the case then it is very dangerous if your router does not support advanced encryption.
and your ISP has nothing to do with this.

We need more information. A "Wireless" internet connection could indicate several things - perhaps you live within a city which has a Municipal City-wide Wi-Fi system, or are you connecting back to your own wireless router, which is connected to your OWN Cable / DSL connection?

Both have their own faults, but the former is bound to have more security concerns than having your own connection.
