Wireless Routers and Hacking.

Is someone with a wireless router vulnerable to an attack?

What steps would you take to protect oneself?

WEP and MAC based authentication.
 
You have to have a wireless NIC too but yeah. Encryption layers are built into the system and usually the OS so for the most part you have a decent layer of defense.
 
My Router sucks....I need a new one. I bought the one from Dell and it is crap. Would there be a problem with my card if I was to buy a Linksys?

I bought the G-Series wireless router and am very pleased, its pretty fast w/ the G series carb but works with b also.
 
unless you're looking for lan x-fer speed, the net speed is going to bottleneck you far below the g's max xfer of 54mb.
 
Now there's routers that support WAP...........stronger encryption than WEP.

Also limit the number of DHCP addresses your router spits out to the absolute minimum you need for your network, and set the lease times high so they don't expire.

dont be fooled bro.

You have to know the MAC before you can get on the wirelan, unless you're nostrodomus there's no way around it.

Combine WEP and MAC and it's a lock.

I use ettercap all day to spoof MACs, it's easy, but I'm already on the LAN so it works.

Quicken? I bet you use Word Perfect or something right?

Go wired.

...or follow the above steps listed and hope for the best. Don't make yourself an easy target....

Do not use DHCP. Only allow certain IP addressess on the 192.168.x.x block. Keep those machines running at all time so nobobdy and use those IP addresses. Use WEP and MAC filtering.
 
My wireless router pisses me off. If I enable WEP, it shits the bed and chokes after heavy use. The only good thing is that the range on it sucks so I'm not too worried.

Both WEP & MAC-based authentication are near useless as far as wireless security goes. They're better than nothing, but not by much.
Combining both of those with a VPN will raise your security level significantly. It will result in slower throughput so I'd go with 802.11g or dualband hardware for new equipment purchases.

That's where you're wrong Mr. Know it all.

WEP & MAC-based authenticaltion provide a 1024 bit ssl secure transfer line, making them the best encryption available for a wireless connection.

As for the 802.11g I personally would choose the 649.94e over that, it's tried and true, where the 802.11g is the untested new kid on the block.

Get your facts straight, Jackass. :rolleyes:

WEP uses fixed keys that are easy to attain via commonly available software such as Netstumbler. Any kid able to figure out how to download can defeat WEP. If WEP is so secure why is the Wireless Fidelity Alliance is already proposing new standards to replace it?

Pack it up, pack it in

Bro I just made a bunch of shit up, I have no idea what any of this crap is.

Most access points allow you to set your own WEP key.
Can guess my 1028b WEP key? Can you guess my MAC address? No, and unless you have _both_ you cannot authenticate to my wireless LAN.

VPNs won't cause a significant latency, especially since most VPNs for home use do not use encryption, they use tunneling technology which is a far cry from encryption.
 
Are there any *good* consumer grade wireless routers that have VPN working? I've seen routers that say they support it, but the reviews I've read have been less than stellar with VPN support.

Is it just me or are wireless routers kinda flaky? I'm not talking about the range, I'm just talking about the stability of the box itself. I've not been impressed with the two that I bought.

Yes, an attack from the Ffactor! Consider yourself bitch slapped! There is nothing you can do to protect yourself from my evilness!

We run our non-secure network on 802.11g, we are constantly resetting the commercial routers we use. Even when we used 802.11b they required frequent resets.

I can only imagine the consumer stuff is similar.
 
That saved me some money... I was about ready to dump some $$ trying to get a more expensive commercial model. I'll stick with the cheaper ones with the same problems.

NetStumbler software also allows users to determine the Media Access Control address of an access point, and can help a user determine whether the built-in Wired Equivalent Privacy (WEP) protocol is turned on or off. The software also has hooks that allow the use of a Global Positioning System receiver to precisely determine the location (within 10 meters) of a given access point.
There are also several programs available that can crack WEP, so I stand by my earlier statements.
VPN's can and will reduce the throughput rate, depending on encryption level and hardware. My Cisco 501 does 10Mb/s throughput but only 3Mb/s or so using 3DES encryption.

The 501 is an enterprise class PIX. You can increase throughput by presetting keys or by reducing the frequency the keys roll.
