Question Blocking other users from accessing my router

After having the wireless router setup and connected, what is the best way to block other people from accessing it? For example, if my friend comes over with his wireless laptop, will he be able to automatically detect the access point (router) and surf the Net? If so, how can I keep my PCs active to the router but at the same time block all the other PCs?

Hmm its definately possible to hijack a wireless connection, i mean, just google it and you've got yourself a guide to stealing other peoples bandwidth without their permission, yet knowledge
First off, you will need to obtain the MAC address of the networked computer in which you would grant authorised access and then add it to the allow list

Are MAC address permanent or do they refresh itself everytime the PC is booted? I think my computers uses the same IP address all the time. DOn't know about the MAC address though.

A MAC address is one level lower than an IP address. MAC addresses are burned into hardware and can never be changed without getting a new network device, but it is possible to spoof them. Your wireless router should have MAC address filtering. Find out the MAC addresses of the systems that you want to allow on your network, and allow them access to the network. All other MAC addresses will be filtered out. Also, setting up a password for access would be a good idea.

You could also encrypt your wireless connection, but MAC address filtering is definitely more secure. To deny others access to your router, all you have to do is set a router password.

I think that both an encrypted wi-fi line and mac address should be used
MAC addresses can, as spank fusion said, be spoofed by googling it
Lol you can get everything off google

I will try this idea with MAC address filtering with my D-Link router. THe manual it comes with is very broad so no help there. I'll try to play with the router interface through IE and see what I can come up with. I'll let you guys know how that works out.


Ok, I did the MAC filter as suggested. I added my two PCs unique identifier to allow access to the Net and it is running great. I don't really have another wireless PC to test but I will trust D-Link that after setting that filter, my two PCs are the only PC that can access the Internet. As far as outsiders accessing my LAN, well, I don't care if they get in or not or can they? I have nothing else shared except for what's in the Shared folder (nothing in there worth hijacking).

Yeah I know you can spoof your MAC address, I even linked a tutorial on this here:

http://www.computerforums.org/showth...t=19253&page=2

Sure someone could spoof their MAC address, but they would have to know what to spoof it to, since there would only be a few MAC addresses allowed to connect in the allow list. The average person won't need to use both security precautions, anything can be cracked especially WEP since it's so popular these days.

Default Re: Blocking other users from accessing my router

So it seems like there is no secure security measures to take. I have two PCs under the MAC filter list to gain access to the Net. All others are blocked out. It seems good, but I had no idea just how effective they are now, after reading your links.

Well as dyserq said, you could always use both WEP and MAC filtering. Honestly if someone is trying to break into your network and they discover you're using both WEP and MAC filtering, most likely the "war driver" or who ever will just move on to the next guy with no security.

WEP is for wireless connection right? I'm looking on my D-Link menu now. If I select WEP, do I have to configure anything else? Do I go with 64 bit or 128 bit encryption? HEX or ASCII? Under HEX, it says Key Type and "00000000000000000000000000" next to it. Am I suppose to put some random numbers in there?

Also what type of Authentication? Shared Key or Open System?

I would go with 128 bit encryption over 64.

Might want to read some of these links:

http://www.webopedia.com/TERM/W/WEP.html
http://netsecurity.about.com/od/quic...ess+encryption

If your going to be using 128bit WEP, your key should consist of 13 hex digit pairs.

Default Re: Blocking other users from accessing my router

I setup WEP, but my laptop lost connection with the router. Couldn't connect to the network. I don't think people will hack into my network unless they are really close to my house right? What is the range anyways where people can actually access the routers signal? Even if they do, my LAN is private right? My routers got the MAC filters in place so I should be all right. Even if they get into the LAN, they can only access what's in the Shared folders anyways which is empty.

I have a D-Link DI-524 series wireless router.

Your main worry if someone gets into your wireless LAN shouldn't be what files they will get, but what they will do with your connection. For instance if they did something illegal online with your connection, guess who it would be tracked back to; you.

What I do that works really good is on your router turn off dhcp broadcast and statically assign all your address for your wireless network.(make them ip's that no body will think of) and there you go some little kid who thinks he is all kool and hacker hard core connects to your network and does not even get a ip. hah You could password it but nah takes too much work you can do this on most routers.

Default Re: Blocking other users from accessing my router

Ok guys, guess what happened to me? I was messing with my router and accidently locked myself out of my own network-if that's even possible. I tried to reset it and fiddled with it somewhat then this screen pops up and tells me that I have updated the firmware incorrectly or something like that. How the hell did resetting it accidently screw up the firmware?

Now the router is all messed up, the status light is constantly blinking at regular intervals, I'm getting no signal going through it, basically, I am screwed. Firmware probably got corrupted.

I got so upset, I slammed the router on the floor and broke. Think I can still RMA it? j/k...

Anyways, I ordered a new wireless Linkysys router through Newegg. D-Link makes great routers, but my curiosity got the best of me and led to its destruction. Instead of buying the same router, I get to try Linksys now. Yay, what fun!!! I hope it gets here in a few days. Then I'll post any trouble I have with it, but hopefully not. Reviews look good. Install seem easy and flawless. Good security with it too.

Now, I'm using a direct link with my cable modem to the NIC off of the motherboard. Man, what a night.

A reply to an earlier post, always get atleast 128 bit encryption is you really are going to secure your data or connection, 64 bit encryptions are like an excercise for hackers
How did you lock yourself out ? Haha, i've never heard of someone rejecting their own requests to connect, i mean your computer has a continuous loop service to itself ...

HOnestly, I have no clue. I was trying to test the security for the MAC filters by denying my laptops MAC address, but somehow lost the whole darn connection. FUrther tampering made it impossible to get going again, even after resetting it so many times. This is too funny.

I hope to get three or possibly four computers on this network soon. I've got spare PC sitting on the shelf for the last 4 years. I plan on gutting it out though with new hardware so that should be fun. Have to wait until after I pay for school's tuition though.

lol TRDCorolla, i'm sorry but locking yourself out of your own router is just too funny.

Is this even possible? Man it's weird. But anyways, I will relate all the response here and apply it towards my new router, yay. Hope it works just as good.
