Default Preventing illegal access to Wireless LAN

I have just installed a wireless/router/modem with one computer on a
wireless link and the other direct on a USB cable from the router. It is an
Origo router.

Can any neighbour use my router to get on the internet? If so how do I
prevent it?

TIA

Its not illegal to use a wifi connection that is publicly avaliable unless
security has been broken.

Turn on WEP Encryption that should be standard, ensuring that you don't just
use the standard password settings.

This should be detailed in the manual.

Default Preventing illegal access to Wireless LAN

Then set your router to only accept connections from MAC addresses of the
hardware you have, and nothing else

MAC address filtering is a waste of time. For the average user they are an
inconvienience and for those with knowledge, easily spoofed.

why easily spoofed? Use MAC filtering myself.

Its trivial to sniff the connection and find out what valid MACs are
flowing.


Encrypting the traffic with WEP 40bits, WPA-PSK, or authenticated logon
using something like 802.1x is far more secure.


Here on my home brew AP I use PPTP and

Sorry, not so...

Under Section 1 of the Computer Misuse Act 1990:

1. A person is guilty of an offence if
* he causes a computer to perform any function with intent to
secure access to any program or data held in any computer
* the access he intends to secure is unauthorised; and
* he knows at the time when he causes the computer to perform
the function that this is the case
2. The intent a person has to have to commit an offence under this
section need not be directed at
* any particular program or data
* a program or data of any particular kind; or
* a program or data in any particular computer


In a nutshell, if you know that you are not authorised to use a computer
system then it *IS* an offence regardless of whether you broke through
any security to gain ('secure') the access.

To answer the OP's question: using WEP encryption would be better than
no security, WPA would be even better. Having the Wireless Access Point
not broadcast its SSID would also help.

The best way forward, of course, is to assume that whatever you do you
will never be 100% secure.

Yes I know, I wondered how long it would take.

However: there are many computers \ wificards that will simply pick up a
wifi connection if avaliable, and many (or at least some) that are
intentionally open.

It could be considered that it is not obvious that access is unauthorised if
security is zilch. If wep was on with default settings however then it would
be a different matter.

There is also the issue that actually the person isn't securing access to a
computer or any data by picking up a wireless access point automatically and
browsing the net. Whilst technically this is no different to going in and
seeing what data is avaliable on local computers, in practice the majority
of people picking up open access points are unlikley to do anything bad,
only use the internet through it.

The fact that the law is rather ambiguious could be why there have (as I am
aware) been very few convictions.

True - its all relative, most of us don't have anything worth getting at on
home networks, so discouraging casual browsing localls and free net access
is probably enough.

While it's certainly not foolproof, it's another layer of security, it
costs nothing to use, so it basically free. Use it, but don't rely in
it by itself. Used in conjunction with WEP, and hiding of SSID,
security will be just fine. If you are mega paranoid, change your WEP
keys every couple of weeks.
