Hi there,
I think that my neighbour man unasked my Internet shared my question is
can someone explain me how I can protect my wireless lan in advance ?
thank.

1. Learn to write proper English. You will have many, many more questions
to ask of us on this issue, and you will find you will get better responses
if you avoid non-English constructs such as 'neighbor man', 'Internet
shared' and the failure to separate sentences with periods.  I hope this
does not offend you, but it's a fact that the better English you write in
queries here, the more useful the responses are.

2. Employ security measures to restrict access to your network.
a) Change the name of your access point to something which is not a word
or series of words in any language. Mix it up with numbers and punctuation.
b) Avoid broadcasting the name of your access point.
c) Reorient your antenna(s) on your WAP and use passive reflectors to
limit where your signal goes. If you put the WAP in the corner of your
house closest to him, and put reflectors between the antenna(s) and his
house, you will radically reduce the signal strength going in his
direction.
d) Employ WPA security. Sadly, WEP 128-bit security has been cracked, and
WEP 40-bit was a very bad joke from the onset..

These four simple and inexpensive measures will provide you with a much
more secure wireless system.

Who would disagree?

If by "name of your access point" you mean the SSID, this is
worthless advice and provides no additional security

This is bogus security. While it may give you a false feeling of
security, the SSID is *always* transmitted and cannot be hidden.
Disabling SSID broadcast will cause certain things to either not work
at all or not work well.

Agreed. Encryption is the best security.
On a home network, WPA-PSK is more likely than WPA (which implies
IEEE 802.1X and a RADIUS server)

Sort of. It is certainly true that WEP is insecure. However, the time
it takes to crack is often exaggerated. If the network does not have
WPA available, then WEP encryption is the next best line of defence.
Note that some networks (for example, many (most?) WDS
implementations) cannot use WPA and may have to fall back on WEP.

Network security (wired or wireless) is based on authentication and
encryption. WPA (good) or WEP (less good) are intended to provide
this.

Reducing the footprint of the wireless signal is a good idea, but is
not 'security': other than encryption, the other advice is worthless.

Sorry if this sounds harsh, and I'm not attempting to start a flame
war, but please do not attempt authoritative advice with what appears
to be limited, perhaps second hand, knowledge.

Usenet is a medium where all are free to post - but many find that
advice is worth precisely the price paid for it.

Kind regards

Dutch.

Those ideas are actually pretty useless for adding any sort of security to a
wireless network.

Turn on MAC filtering, if your wireless AP/router supports it; won't
stop anyone from seeing what's going over your network, but it'll
prevent them from using it.  Encryption, of any form, is better than
none.  Don't bother with changing your SSID; making it weird just makes
it "interesting" to war drivers.  Leaving it "netgear" or "dlink" will
make you look more boring.

Linksys or Netgear?
