Things like Kiddy Porn or Terrorist Material can be downloaded through your WiFi Connection and the authorities will consider the owner of that ISP Connection responsible for the download. 3. can they control your computer Depends on what OS you are using and how secure it is. But if you are talking any Windows System then the answer is most defiantly yes. 4 how long would it take then to hack the secure code. If you mean WPA2 under 10 seconds if the person involved knew what it is that they are doing. If they do not know it will take longer. If you do not run WPA2 it can take considerably less time and if you have not changed the Password on the WiFi Access Point anyone could enter it's URL and be in within a few seconds.

But you can set your router up to only allow specific MAC addresses to connect. + 0 Votes Oh yes. mjd420nova Updated - April 5, 2013 at 2:14am PST All of the above. There are things you can do to make the infiltrators access harder to achieve their goals. One is the MAC address filtering but even that isn't that secure as the address can be spoofed. One way to limit outside access is to insure none of your WIFI signal leaves the premises. Working with a laptop outside the home could identify signal levels and changing position of the router and its antenna(s) can create usable signals within the home but not outside. Some signal peaking areas can be reduced with grounded foils to block signals in certain directions but this can also inscrease the signal in others and is all variable depending on the environment, wall insulation, wiring and innumerable other variables. + 0 Votes I hate to mention this but TRgscratch April 4, 2013 at 6:37am PST if your brother has "wires running all over his house", but has a wireless-capable router and not disabled the wireless connectivity in it, then he is vulnerable as several posters have noted. + 0 Votes What ever happened to Charles Bundy April 4, 2013 at 11:46am PST we at Techrepublic do not encourage or respond with info on how to hack systems. It seems like a line is being crossed here (or at least fast approaching.) + 0 Votes Wires may not be that bad. ericson007 April 4, 2013 at 11:35pm PST If you have some hardware lying around. A good way of protecting the wifi a little more is to run it behind a firewall. Also before having access to the net to have a captive portal to authenticate through, if possible also WPA 2 - Enterprise. Not really likely to keep out someone really determined, however, it will beat almost certainly 99.9% of the script kiddies. Your brother is a very smart man though. With the ever increasing speeds of ISP services, I do not understand why you want wireless. At home here I have a 1gbps up/down fiber connection. Connecting to that with a wireless device loosing 480 mpbs on my last test, I would rather just stick with wire as well. Ever tried CIFS shares from a cheap non enterprise NAS over wireless. It's a dog, not that it is the fastest protocol ever, but wire does help data move along. Especially in the U.S. where walls are generally dry wall. Cutting away, pulling wire and fitting a wall cat 6 plug is not that difficult and really increases the neat factor. + 0 Votes 10 seconds - A little ambitious even with rainbow tables! -gargravarr- April 4, 2013 at 11:38pm PST As with any password mechanism, choose strong passwords, If you're going to use WiFi in the home use WPA2-PSK there isn't another choice at the moment. choose long complicated passwords >30 characters long. Yep, its a pain to put in but how paranoid are you going to be in a home environment. Setup WPA2 - enterprise with a short key rotation. Setup an IPSEC tunnel over the wireless network.
