extremely useful info guys considering i was just thinking about getting a laptop myself instead of this crummy stationed comp <img src="/images/graemlins/wink.gif" alt="" /> anyway wireless would be the way to go eh? btw i have cable so i have no idea what a hub is, can anyone tell me?

Don't mean to but in or anything but eh, if that hacker knows what he's doing he doesn't need to guess such a code. I mean they just write some decryption key if they don't already have one.

But then again no hacker of this calibre would go through the trouble hacking into home user's computers. Allthough i still think that a wireless connection is more vurnarable than a normal one, coz it uses fairly strong signals that can be picked up pretty easy especially by someone in your neighborhood.

Interesting comments here thought I would jump in.I agree wireless is less secure but for average home user should be good.Just enable WEP(wired equivalent privacy)which will hand a encrypted key out for each user on LAN and anyone scanning your net will not be able to get on without key.Also about the hubs which work at layer one (which it just regenerates signals coming from your PC) I would recommmend getting a switch which is probably same price and give each PC full bandwidth to internet.Which a hub will slow down your network because of collisions.(hub does not filter traffic)..Thats all for now hope that explained it as simple as possible?

Hmm we have quite the network at home all wired.
Internet comes in trough a router, then enters a hub, which goes to 4 computers, another hub and a printer.
the other hub goes to another 3 computers.

My dad had a wireless sender box thingy.. not knowing the name sorry. he plugged it in the hub, so his laptop could receive wireless lan while he was sitting outside in the sun.
However as soon as the wireless sender box thing was plugged in the hub, the internet connections for all the computers that were wired to it were dissconnected, and refused to connect.

Anyone know why this could have happened and how to solve it ?
