Question about Linksys Wireless-G Broadband Router

3 Answers

Thief cloned one of my MAC addresses to get around my MAC filter on my DI 624. Have WEP security set, because I tried WPA2 and couldn't get any of my computers to connect with it. Have disabled Wireless until I can figure out how to shut down the thief. He's been stealing our internet access for quite some time, and every time I turn the wireless back on, he's back around whatever I've put in his way to stop him. :-( Any suggestions - other than keep the wireless off? We have a laptop that travels the property, and wireless would be quite helpful if it weren't for the thief. ( even named his old MAC address Thief )

    see him connected, denied his old mac address, he sniffed our laptop MAC address, cloned and jumped back on next day. Our laptop was off, so not connected, but there it was connected - so, assume him. He has to be boosting our signal too - no one within 1/4 mile other than us. Don't know why he can't just pay for his own #$*(#& internet access. This is getting annoying. I've been parked on my router page for days watching him come and go, trying new things. I think this **** thinks it is a fun game. Wish he'd find a job!

    Can't see his computer name. I named him Thief when denying his old MAC address, he showed up "unidentified" before that(our computers all have names)

    Have changed SSID, but don't know how to disable broadcast. Was actually just checking into that. But, from what I've read, he can just sniff that too, especially if he knows how to sniff our MAC addresses. He must be a computer geek, and I suspect someone about 1/2 mile away, but don't know how to prove (other than find his Network Card and look at the hard copy on it of his MAC address, since he changed his computers MAC address through software.)

    Thanks for asking questions. Hope something here can help you give me some direction. I hate to just have to stay hardwired.

    Shuttle -
    Long Preamble????
    LAN side protocol analysis test point to monitor???

    The rest I get.

    He actually jumped on me long after set up. Had the same system in place for a couple years. Have changed SSID regularly, but not disabled, which I found the setting for just now. He showed up first about 6 months ago. Did most of what was suggested back then, including unplugging the LAN between router and modem when not in use, and he got bored, but came back in the last week.

    I hadn't been monitoring the MAC address connections until I noticed internet activity when our three computers were off (modem and router were on though). I have to monitor usage because we are on a limited usage plan - which makes it even more annoying that he is using over 20MBs an hour when stealing our access. Got us throttled this week!!!


  • the_great_za Mar 06, 2009

    Is there a way to just change my router address again instead of getting a new box? (already changed once due to conflict with modem) so if he is accessing by router address and cracking my router password, he would have to try finding the new address? Can't use 192.168.0.1 or 172.16.0.1 I don't know what other numbers to use for a router address, do know how to change it.

    I've been changing my router admin password daily, or even twice daily, this week hoping to keep him from cracking that and adding any filters for himself. I have reset box twice to factory and then reset SSID, password and box IP. Previously had it set, but hadn't changed for a while. Also changed the User password this week. If he cracks the password, he will know in no uncertain terms what I think of him ;-)

  • the_great_za Mar 06, 2009

    Can't change location of router because of hardwiring issues where modem already is, then hardwiring back to non-wireless equip. But that would be a great suggestion otherwise. Currently signal won't travel more than 20 feet radius outside of house, so he must be boosting on his end. Can't even get signal in basement. I have shut down the extended range option, he still found us.

    Would love to force him closer, but I think he's too lazy to come closer. Don't know if he knows where we are (woods, hidden houses, etc., he probably doesn't have a clue whose signal he's stealing - no identifying names, no inter-networking of computers on router, no sign he's hacked any of the computers, just the internet theft - I'd like to keep it that way)


  • the_great_za Mar 07, 2009

    Changed the preamble to long, reduced broadcast strength to 50%, increased beacon interval, and changed SSID and disabled broadcast of SSID. Also, turned off the extended range, changed passwords, renamed so not "admin" to access router anymore.

    After all that, turned wireless back on and set up laptop. I had to enter the SSID with the laptop to access non-broadcasting network, so that was a good sign. Now, I'll just leave the wireless on for a few days and see what happens I guess.

    All the advice was helpful. I'll let you know if it works. Am still open to further suggestions. Thanks. Z

    Hi, what wireless are you using b/g/n? How do you know hes connected to your network do you see the mac being used in a list?, are you able to see his computer name through Network connections? You could attempt to change the SSID name and then disable the broadcast.

You could attempt to shield or point your antennas to keep the signal in the house, maybe move the router to the basement, disable any signal amps in the software if any. Unless you want the signal outside that is, but you may be able to catch who it is if they need to get closer to the signal or detour them completely.

Can you use WAP encryption instead of WAP2.?
WAP is a stronger encryption than WEP 128bit but not as strong as WAP2.
Only other alternative if you wireless router supports WAP2 and you wireless cards don't, then upgrade/replace the wireless to later cards that support WAP2.
I agree with elec2410, change SSID and turn off SSID broadcast, continue with MAC address filtering, enable WAP2 and change the default admin password.

    If your wireless router has 10baseT ports you can connect your computers using network cables, and if you need extra 10baseT ports you can run a network cable from the router to a hub and connect your computers to the hub and remove the antenna/s off the wireless router. You may be able to turn off the wireless function on the router, if you can't it doesn't matter, without the antenna there is no wireless access. The only problem is that to get Internet access in your home means you have to be connected to the router by the network cable.

Hello the_great_za,

You are going to have to do some clean-up work. Get a new router,keep the old one because it will come in handy.
Way to configure the new router:
1) configure WEP with the following settings
128 Bit or higher
4 WEP Keys (rotate them monthly)
Set Broadcast SSID to off
Use the long preamble
Set beacon broadcast for a long duration between beacon transmissions.
Get all of your PC together and configure them away from your house only turning everything on when at home.

Now what this will do is eliminate the entry vector, remember he is jumping on your stuff when your are setting it up, don't do this at home do it someplace else. (setting up that is). Then what you need is a LAN side protocol analysis test point to monitor for his presence.

Doing this will scare him off.

    Hello the_great_za,

    On the D-Link router you have when you setup your wireless it asks if you want to use a short or long preambe, using the long peramble insures capatability, the short preamble may not work with all wireless systems, and one other strange fact I have noticed this the long preamble causes the beacon time to be increased (time between beacons).
    LAN side protocol analysis will give you insight into what attacks thief is using to access your system, this will allow you to mount the proper defense.

    Thank you,

Your laptop should be able to automatically find the network name and security type. (You would have set up all of this, by the way.)
You should then type in your security key/password (you should have set this up when setting up router for first time, also) and then you should be connected to the internet.
Your laptop might not have wireless capabilities, so you might have to buy a wireless network adapter.

WRT120N Linksys router will not connect to Vizio Wireless Blue Ray Player. Need to lower the security to connect to Blue Ray Player.


If anything it's the other way around; the blue ray player needs to connect to the wireless router / access point. Can the blue ray player be configured to work with a WEP/WPA/WPA2 secured network? Check the owner manual or go through the setup menus to see if there's a way to set up a new wireless network and configure the password for your wireless network on the blueray player. The other thing to check is to see if the router is filtering based on MAC address. You can probably disable that feature without losing much security since MAC addresses are easily spoofed.

How to secure my di 624 router?


You need to log into the wireless router either by a computer that successfully connects wirelessly or by physically connecting with an ethernet cable. Once connected, log into the router by open a web browser (Internet Explorer, Mozilla Firefox, Google Chrome, Apple Safari), and typing the router's address (usually 192.168.1.1 or 192.168.0.1) into the Address (or URL) line. The default usernameand password is usually "admin" & "admin" or "admin" & "password". Once successfully logged in, look for a tab or link that says "Wireless" or "Security". You'll be able to change whether security is enabled or disabled, and the password associated with it. Your security options are WEP or WPA (or WPA-PSK). WPA-PSK is the most secure, but WEP is also an acceptable choice. Select the security option of your choice and either enter text into the passphrase generator or choose your own password and type it into one of the security key text fields. If you use a password that is not a plain english combination of letters and numbers, be sure to write it down so that you can enter it as needed on other wireless devices that need to access your router (ie-pda phones, game consoles, laptops, desktops, etc). Be sure to save changes so that the security settings and password is saved.
Let me know how you make out.

I have a DI-624 connected via ethernet to a Mac G5 and an XP Desktop PC and an XP laptop via wireless. In the browser, I can get to the router by typing in the address from the desktop PC, but not from...


Check the web-browser settings on the Mac -- "disable" any usage of a proxy-server.

Or, try a different web-browser, in case the web-browser on the Mac cannot properly handle the web-pages that the DI-624 is sending.

Try to MAC Cloning first. Open the router's admin page and look for MAC Address Clone setting. Enable it and save. You must power cycle the router and the modem after that.

Cannot connect iMac with DI-524 over wireless! Please help!


The most likely answer is that you have an access control list (MAC Address filtering list) set up on your router and have not added your Mac's MAC, also called your Airport ID to the list but there are other possible causes.
Double check that you do not need to add your MAC address to the list, that you did save changes when you removed security from your router and that your PC can still connect.
The hardest part of moving from PC to Mac is learning to trust your computer to do things for you, with Microsoft's OS's you don't just trust the automated set-up wizards because even in the rare circumstance that the wizard actually works you invariably have to finish the settings manually.
With your Mac the exact opposite is true, if you try to do everything manually it'll invariably mess things up, where as using the wizards and trusting the computer to manage things on it's own reaps obvious rewards.
If Airport set-up wizard is asking for a WEP key and leaving the field blank doesn't work you can be comfortably sure that the router has a key set up on it. (BTW: Always be mindful of the fact that WEP is pointless, even 128bit.) 
Check that your router has not been hijacked and that you have indeed removed the security from your router, is it possible that you have a WPA key set up on the router? Unlike WEP, WPA and especially WPA2 actually secure your network (in as much as is possible). 
Another major cause of connectivity issues for new Mac users is having Norton Internet security installed, for a PC user the idea of not having full-on paranoid security installed is anathema, the idea that your Mac's inbuilt firewall alone is plenty of protection (at time of writing) Other than that ClamXav antivirus will protect your Mac form any viruses that may appear in future. Norton Internet security for Mac is often pushed on buyers by stores that don't know any better, to be honest Norton Internet security for Mac is an awful lot of hassle and performance loss for little or no advantage.

Using a Mac is different to using a PC but once you have got used to using a Mac you will not be able to change back, once you have learned to trust your Mac to do things for you, you will find Windows (any version) to be painfully time consuming, unstable and fiddly to use.
Post back if you are still having problems. :)
