Well your already connected to the internet, your also communicating with the router or you wouldn't have been able to open the router up in a browser to clone the mac address.

It's done!

The next step is setting up wireless Security if you live in town or have neighbors close enough that they might beable to get your signal.

Then set up a workgroup on each computer so you can start sharing files between them.

BTW sorry for teh link, it doesnt open for me either..... dont know what happened.

 

what is a workgroup?

 

To configure the wireless, all you have to do is log into the router, you do not need any software or CD's. I usually keep it simple and basic - I use 64 bit WEP security, and use my 10 digit phone number for the key. That's good enough to keep casual neighbors out of your connection. Do change the SSID from the default "linksys" to some other name.

The easiest way to network your computers for file and print sharing is run the home networking wizard on each computer. You tell the wizard that you are connected to the Internet through a residential gateway (that's what your router is). The workgroup name has to be the same on all computers, the default is either "workgroup" or "mshome".

 

ok well I cant connect to the wireless network, I entered my key and still didnt work Its putting off a full signal.

 

A workgroup is: A group of systems within a network that share specific resources.

You have to set it up and name it so that the conmputers know that the other one is allowed to talk to it and share files with it.

This will walk you through setting up your network, both wired and wireless as well as help with security...

Assuming you have XP

Actually this is the exact page that you need ot set up the computers....

http://www.microsoft.com/windowsxp/u...p/homenet.mspx

 

and this will help you set up the wireless both the actually connectin via wireless and the security.

ohh hey, a fun and way to name your network "the SSID". so you can identfy it from any other wireless in your neighborhood, when connecting the computer..... name it something like

Built54.virus.worm

as soon as you see it in a list you will know it's yours and if you have paranoid neighbors that maybe arent to smart, there is no risk of those type of people accidentally clicking on your network and accidentally connecting, acidentally stealing your internet, becasue they will be to scared that it's a virus to click on it.

 

Never, ever use WEP!

If you are running Win XP SP2 or Vista and have a recent router with current firmware ( and you should always ensure your f/w is current - check the router manufacturer's website periodically), choose WPA2-PSK. It's the ONLY security protocol with NO known exploits. For a key, you can use a gobbledygook 'pass-phrase' instead of a number - make it at least 16 characters - the more the better. Write it down somewhere safe.

WEP is the next-best thing to a wide-open connection. Ten-year-olds with laptops & free tools are cracking those like walnuts.

BTW - in the router's advanced settings, enable MAC filtering - allow only your specific MAC's; don't bother hiding your SSID - a number of tools can reveal that anyway, and it causes your router to broadcast this in the clear - which can allow someone to spoof it.

There are a number of security whitepapers on MS's sites - good reading. Debunks a lot of urban myth surrounding security settings.

 

ok now I cant connect to the internet through my router, I think i messed something up, maybe thats why the wireless wont work...

 

It all just keeps honest people honest, if someone is going to hack your network, then they will. Nothing is bullet proof. With current hacker software even I can be in any network, in less than 5 mins,
by sitting across the road with a laptop.

 

Not with WPA2. Not yet, at least.

"A word about wireless security, you do not want to use WEP. WEP is hideously insecure, so much so that the FBI cracked a WEP key in 3 minutes flat using Kismet, Airoplay, Airdump, and Aircrack. You will want to use WPA2. Now, the bad news. WPA/WPA2 has a significant vulnerability as well. If you use a short passphrase consisting of a word that can be found in the dictionary, you will be vulnerable to an offline dictionary attack. Now, the good news. This is the only known effective hack against WPA/WPA2. You will want to use a randomly generated string consisting of at least 34 characters. Most publications say 20, but I recommend at least 34. The reason is that you get about 2.5 bits of security per character plus 12 bits. (2.5n+12) 20 characters would equate to 62 bits worth of security. It is computationally feasible to brute force a 62 bit key. It will take a while, but it is feasible. You want to have at least 96 bits of security, and at 2.5n+12 it takes 34 characters to achieve this. Ideally, you want to use a randomly generated 64 digit hexadecimal. This will provide you with a full 256 bits of security. This approach also has the advantage of avoiding the hashing process to create the Pairwise Master Key, because the hex is used as the PMK. It is this hash that makes WPA/WPA2 vulnerable to an offline dictionary attack. Now the really good news. If you use a 64 bit hex as your PSK, then you will be reasonably well protected against any sort of brute force attack. So, what do I mean by reasonably well protected you ask? Since a 64 bit hex will not be found in a dictionary file, your would be hacker will have to resort to a good old fashioned brute force attack. This means he will have to check each of the 2^256 possibilities. This is a huge number, 1.1579208923731619542357098500 869x10^77 Like I said, big number. If you could produce a device that could do a billion billion possibilities a second (No such device exists at present) it would take over

3.671x10^51 years to exhaust the possibilities. Since the age of the universe is believed to be 15,000,000,000 years, I believe this qualifies as reasonably secure. Especially since the most advanced brute force device to date can only do 256 billion keys a second (this is something that your neighborhood wardriver is not likely to have) If your equipment does not support a 64 digit hex, then you can use 63 character randomly generated ASCII string. This only give you about 169.5 bits of security, so it will only take a device doing a billion billion possibilities a second 3.35336091374264796951088635x10^24 years to exhaust the possibilities. Again, this qualifies as reasonable secure. In summary, if you use something like



“sausages”



Then your local wardriver is going to have you for lunch, and it will take anywhere from 0.2 seconds to about 5 minutes to hack your network. However if you use something like:

DE9350EB9F96D947A962E5C9D71A6F5FC3DE5D006BF1340400 050D30354AF49F

(a 64 digit hex)



or



>66X>XC'kidz^7{u(,v}*C&-X\[|hl}?@O>Kc6w6>goGNB**wO"",0ADq]x*yUg



then your neighborhood wardriver is going to be busy for quite some time trying to crack your network. If you do not have a program that can generate these sorts of values, go to:

what did you change?

If you cant remember.
Log into your router
go to administration tab
then teh factory defaults tab, restore factory defaults

then just go back and clone your computers mac address...
then the staus tab, release and renew DHCP.

then start setting up the wireless again.

 

Ok how do I get back in my router, I have to connect directly to my modem to be online right now

 

One quick google search

that hackers blog clainmed to be using those on WPA2 PSK

Also found programs called AirPcap and cain that several claim do the job relatively easily.

as I said nothing is bulletproof.
The software is out for hackers ussually before the technology is out to the public.
