How can i stop someone using my wifi

toejumper

just by chance i had a look at the devices setting on my modem and found someone has been using my wifi 1 unknown and a Jerald TOSH, had a look at my security and all seems to be fine, security key protected and password protection, so how did they manage to get in. I have now changed all the pass words and pass key, but if they manage to get in again how do i stop them.

what level of wep security? make sure both your windows and router firewall are on //

u could try disabling the SSID broadcasting too so that it is not viewable to others /

Using a BT Home Hub?

Best advice is to disable wireless, and enjoy the greater speed of an ethernet cable.

Failing that, use the best security possible:

• if WPA2 is offered, then use that.
• If 'WEP' is the best offered, then ditch the router as this can be cracked in minutes or less
• Use a randomly generated wireless key to prevent brute force/dictionary attacks.
• Set it to only authorise devices you want with MAC filtering

People will point out correctly that MAC addresses can be spoofed, and that hiding SSID won't do a thing if people are using the tools to crack a network. Doesn't hurt to set it that way, as at the very least no one will see your wireless in the standard view and think "I wonder if I can crack that".

I have WPA PSK can i run windows firewall aswell as pc tools firewall

closed

no stick to windows firewall if you want a speedy pc, and neither will stop people using your wifi (if they really are)

If you are using WPA then they've not got in. They will be connected but their laptop will be sitting there asking for an IP address. The unknown might actually be one of your own computers - most routers put unknown until they've resolved the computer name and also games consoles get identified as unknown unless you've entered their MAC address manually so it knows.

I have named everything that's using wifi tv printer and dd netbook so will see if anything untoward happens, is it a a good idea to turn the SSID broadcasting off though, will it affect anything in the house using the wifi
