Security by Obscurity ;-)

The only way I can get the Netgear WNDR3700 and the ZyXEL WAP3205 to work together is if there is NO security.

Obviously, not an acceptable situation.

However, what if I entered the MAC addresses of the devices I would allow on my home network into the wireless radio devices. Would that keep others out?

Thanks.

Spoofing a MAC address is one of the easiest "hacks" someone can do if they're trying to gain access to your network. All of the MAC addy's for client devices are broadcast in the clear, which gives a malicious user a handy list of authorized addresses.

Mac address is not a security function or tool. Shouldn't be used like one.

This is all quite new to me.

I have Wifi Analyzer on my Android phone. It displays APs. Should it be able to see those broadcast MAC addresses? If not, what tool will see them?

Kismet is what have used. Wireshark is also a good tool for packet viewing or analysis.

OK, I have INSSIDER 3 running on my laptop. I see MAC addresses of my neighbors' WAPs but not of any devices. I'm confused.

If your laptop only is 2.4 it will not see anything in 5,0.

??? Shouldn't it see the MAC addresses of 2.4 devices?

if the device you are monitoring it on supports 2.4, then yes.

Let's back up a bit. By 2.4 and 5.0, you are referring to the network speeds associated with 802.11n, right? All my devices support 2.4 -- laptop, desktop, three android devices, two rokus, etc.

ok that's a start. Now, do they all support 'n"? Again, if the one listening does not support or has been configured to no use b/g, or n etc. then it won't see them.

The listener cannot see what it does not support or not configured for.

I'm using a Galaxy S3. It (via wifi analyzer) can see any number of 2.4 networks. How can I tell if they are "n"?

The S3 does support "n".

Sorry. I can't speak to this app.

InSSIDer should see all of the networks that the system running InSSIDer is capable of seeing. If you want to know what those are, you need to look at your NIC configuration and look for the frequency 2.4, 5.0 or both; and then also the version, b, g, n, or any combination of the above. How this is configured will vary depending on your wireless NIC.

I think we're talking about different things. Somebody earlier said that spoofing MAC addresses was easy, and I thought he meant spoofing the MAC address of a DEVICE, not a network.

You'll recall that I mentioned adding the MAC addresses of my devices to my router as a way of limiting who could connect to my network.

Incidentally, InSSIDER and Wifi Analyzer see all of the NETWORKS that reach me.

You can whitelist your MACs. Doing so prohibits all other devices not on the whitelist to be denied connections.

That is about all you're going to get for free...

Intertesting. Can you see network packets just floating through the air or do you have to be "on" the network?

Is whitelisting the same as adding them to a table in the router?
