OS X :: Possible To Block Wireless Internet Users?
Nov 19, 2009
I need some info if this is possible, is there any means software wise other then changing the WEP password on my wireless modem to block someone from using it? This person of interest is using a windows laptop with xp and has some kinda of WEP crack program that can find out the password. So hence changing the password is a lose, and I'm not to sure if there are similar programs to WAP based (if not I go and buy an apple airbase with WAP2 password). I was thinking of some means of knowing the I.P. number of the laptop and preventing the modem from having it connect to it.

Is there anyway to block users that are connected via cable ? aka restricting internet access, limiting the speed they get or completely locking them out without removing the cable ?

I been googling and searching for an answer for this question...and all of them say to go through the router. But I was just wondering if there is a way to block computers from using my wireless? Here is the deal. I have a router set up which uses a WPA password. I live in a apartment building so I gave the password to some of my close friends to use. I monitor who is on my network through just looking at the "shared" section on my finder window. I can tell which computers belong to my friends, but every once in a while, an unknown computer pops up. I believe I have seen 3 unknown computers (PC's) - and they do not use the net frequently. I would like to block these computers when they come up. Is there a way to do this without going into the router settings and adjusting those protocols?

Is there a way to prevent a single application from ever connecting to the internet? I have a program that always tries to update itself on startup, but the update breaks it. The preference to never check for updates isn't saved between each quit, and if it detects an update it will start downloading automatically, without my consent.
I've tried using the Security section in SysPrefs to block incoming connections, but that just leaves it stuck at 0% downloaded, instead of stopping the entire process. I'm stuck with disabling Airport, starting the application and getting past the main menu and then re-enabling Airport, which is starting to become a pain. I'll use Little Snitch if necessary, but I only need to block the one application. If there's some kind of Terminal command or .plist file I could edit instead of spending $30 on Little Snitch, I'd like to take that route.

Title says it all. Don't mention Little Snitch, because I need a free way. Firewall doesn't seem to work either.

For specific reasons, I needed to connect my Synology DS211 NAS to my iMac directly via its ethernet port. I discovered that if I share my wireless internet connection (coming from my cable modem/wireless router) from wireless to ethernet, then the NAS would get the IP stuff it needed to show up. did that, voila, NAS is acting like a glorified external hard drive. BUT, when I did that, I lost all internet connectivity on my iMac. Still have full wireless signal. preferences pane says I'm fully connected to my network with an IP address, but safari always fails to pull up any webpages, saying I'm not connected to the internet.As soon as turn off the ethernet PORT, it all starts working again. And to make it even crazier, I discovered that if I leave sharing my wireless internet via my ethernet port ON, but turn off the ethernet port (in pref pane), I can STILL access the NAS just like before. That makes no sense - I'm sharing my internet via a port I have turned off, but it works? Anyway, why would Iose my airport wireless internet connection when the ethernet port is on - configured manually?

this is a major problem for me. I just installed ubuntu on my mac via boot camp, and I can't find how to set up wireless internet! Once, after installing windows, the same problem occurred. I'm not sure whether this version doesn't support airport (ubuntu v10.04.1) or I need the snow leopard drivers (but I can't because it's a .exe file).

I just bought a Netgear router and want to protect my internet access from unauthorized users. In order to lock protect, is manipulation Netgear specific or can I lock it through my Apple desk top?

my family just switched from Verizon Fios to Comcast and we don't know how to set up our wireless routers. A long time ago we had DSL so the routers we have are Linksys wirless-G WRT54G both of these routers are already password protected. The bigger issue when is when I plug the ethernet cable from my modem to the router and click the router's name in Airport it says failed to open page any ideas

For some time now, I have noticed that my Mac's internet is running super slow. I am saying slower than what I see on my PeeCee (Used for gaming such as CSS and Half-Life)! So, I set out on a Google journey to find that a lot of people have been having the same problem with they Airport. It seems that in some Apple updates, the Airports are having issues. So, I tried to fix it and I came up with this wonderful guide. My internet now loads Facebook in 3 sec instead of the 30 sec it was before and I can watch my good old YouTube videos in a flash.
First, Open your "System Preferences";
Next, go to your "Network" settings;
From there, make sure Airport is highlighted and click "Configure";
Click the "TCP/IP" tab;
Type 4.2.2.1 into the blank DNS Servers box, hit return and type 4.2.2.2 then click the "Apply Now" button like so;
Your internet may restart, but it will come back on right after you hit Apply! And your internet should now return to speeds like it used to have. I am running 10.4.10 and I am proud to say my Internet is fast as hell.

So I got a PowerBook G4(1.5 GHz, 512 MB RAM, a superdrive, and an airport card) for Christmas. Before I opened it as a present, my cousin did a clean install of Leopard. My wireless internet goes out every time I try to go to a new page or even refresh it. It's extremely annoying. In order to get it back on, I have to turn my airport card off, and then on again. I was thinking it was my airport card, but then the other day, I went out of town to a friends house.
My internet didnt go out once. I just got back today, and it keeps going out. My home internet is locked with a password, but my friends internet wasn't. However, I previously had a PC laptop and the internet was fine, my cousin has a MacBook Pro, and my brother just got a MacBook. All of them connect to the internet wirelessly and they don't have any problem with their internet. I don't know what to do.

So...I just got my new MacBook Pro yesterday for graduation and I've been trying to connect to the internet wirelessly.
We have a Belkin 54G Wireless Router, which was private but I reset it so I don't think the wireless network is private anymore. So...my Mac now connects fully to the "Belkin54g" wireless network but I can't seem to get on the internet. We also connect through a Motorola modem.
I don't really know the difference between the DCHP and PPOEthingy....and network diagnostics apparently can't help.
I've tried putting in the IP address/subnet mask/etc but that doesn't work either. Sometimes it says its connected, other times it tells me there's no IP address.
If I need to call anyone, who should I call? The Mac people or the Wireless router/internet people?

Today when we started trying to add users to our server (we use it only for afp access at this time), we noticed that new users belonging to a group "storage" were unable to login from client machines via afp (clients both 10.7.2 and 10.6.8).
When we tried editing the users accounts to change which groups they belonged to, it would appear in workgroup (and server preferences) that the changes would take but there was still no access.
As a test case, we modified an existing user who had no issues logging in to belong to a diffenent group and have different sharepoint access. The changes looked good in workgroup and server prefs, but when the user logged in, he was only able to acces his old sharepoint and not the new one (and since his permissions to the old were removed, he shouldn't have access to that sharepoint).
Also, for some reason users cannot be deleted within workgroup manager any more. The login used was the diradmin account.

I am currently am MBA student and must create projects using power point/ keynote, very often. Many of the power points/ keynotes created by students are informative but lack the ability to hold an audience’s attention (boring). Since I have this wonderful Macbook pro, I would like to create a dynamic keynote presentation which would include clips of audio and video files (I already know about converting keynote to power point). The only problem is, the videos I want to use in the keynote presentation are not able to be manipulated in iMovie (due to their format), and if they where able to be manipulated in iMovie, I’m not sure that PC users would be able to properly view them.
What video format (including embedded audio) is able to be viewed and heard by both OSX Lion users and Windows users? If this is possible, can anyone suggest a safe application that I can purchase from the apple app store that will allow me to convert video files (including embedded audio) so that it can be viewed by both Lion and PC users? Preferably one that does not need access to the internet in order to convert the files ( I’m on the go allot and use an air card for internet access), but I will take it if this is the best option. If the app store does not have this type of application, is there a place that I can download a safe one?

I'm brand new to Mac. I just got a MacBook Pro, and I've been having some troubles connecting to the internet at home. I have a LinkSys WRT54GS router with Firmware Version: v1.50.9. I'm unable to access the internet through both ethernet and wireless. Concerning wireless, I have tried connecting using WEP, and have tried entering passcodes both with and without an "$" and "0x" preceding the 10 digit WEP passcode. I have also tried switching the encryption over to WPA2, and still nothing. I have even disabled the security to see if it's able to connect -- it's not. I had some error regarding not being able to find it's IP or something along those lines.

I get internet from my neighbor next door, and where exactly about 18 ft. apart. I know that having a repeater or an external antenna can solve the problem but i cant afford those things right now. I know that on pc you can go to task manager and conentrate your bandwidth percentage to internet explorer, but is there anything like that i can do to my mac? also any other free way would be good too.

My parents are taking a much needed vacation. I suggested to my mom she take the laptop i bought them a few years ago (a rarely used 17" PowerBook). And of course they will need a mobile internet card. But its not like they are jet-setters or use that laptop outside of the house very often, if ever. Their mobile phone carrier is Sprint. But it looks like all their internet card options are for a 2 year contract. I'm looking for something for either a very short or no contract. I even checked through AT&T, which is what i have, but everything seems like a 2 year contract. They get a vacation once every two years . Ideally, i was hoping for a one month data cost and either "renting" (??) an internet card, or buying one if they had to.

This is my first ever mac that I've owned given to my by a friend, so excuse my simplicity. It's a G4 and I have a wireless internet access at home through Time Warner Cable. It doesn't seem to have an airport card. What is the easiest way to connect to wireless? What additional cards would I need to buy?

I have a 2 GHz MacBook3,1 with Intel Core 2 Duo.
My router is 2Wire.
My firewall allows all incoming connections.
My wireless card type is AirPort Extreme (0x14E4, 0x88) -- not sure if that matters.
And of course, I use Leopard.
Anyways, my internet connection has been shaky ever since I bought the computer (January). I always assumed it was my NETGEAR router, because everything worked fine when I was at my university. However, I found out that if I used my computer for too long at the university, my internet went out again.
I just moved to a place that uses 2WIRE as a router, and voila, even though it worked fine for the first day/night, everything went downhill after that.
What internet problems am I having? Here are some examples:Browsers claim I'm not connected to the internet:
Images don't load:Pings don't work:
I already used IceClean to clean up my Mac, as well as Safari specifically. I looked at the DNS servers page for a while (because a few message boards said that clearing up the DNS servers would help things, but only one is listed). I restarted the router. I restarted AirPort.

I recently got wireless internet. Before, the Mini worked fine connected by cable. It has never been connected to a wireless before. The wireless router works correctly, my $250 PC connected to it instantly. There is a yellow light on Airport and it automatically populates an IP address, whatever that means. I haven't installed any new software since it worked with a cable, no funky setup or third party anything- it's just a mac mini plugged into a TV I watch Netflix on and that's all.
My ISP said it's a problem with the computer, the Mac free support could not fix it. I really don't want to pay for an extended warranty or phone support on something basic that this computer should just automatically do. I haven't tried typing in a manual IP address- I don't know what that address would be. If all else fails, I will just run a cable to it again.

I'm using a Macbook Pro 17" 5,1 w/ Snow Leopard. For some reason I'm unable to get an internet connection from certain wireless networks. For instance I was away on vacation and when I returned I was no longer able to get internet access through my work's wireless network but I am able to connect and get internet access from my home network and others with no issues.
I've tried removing the stored networks, renewing DHCP, reseting the router and everything else I can think of. I am able to connect to the router, but the indicator light for internet shows red. My coworker on a similar Macbook is able to connect and get internet from the same network just fine.
When looking at the control panel on the router its showing that his Macbook is being assigned a dynamic IP but mine is being assigned a static IP but there isn't any way to control this through the router and since nothing has been changed in terms of the router's configuration I have to assume its something to do with my Macbook as I'm having similar issues with other networks I used to be able to connect to as well. Since I'm able to get online using certain other wireless networks its bloody well confusing.

I have a MacBook Pro that I have had from about 3 years now. It's been great but earlier this week, it wasn't able to connect to the internet here at my school (college). I didn't think too much of it because my schools internet is always spotty and goes down from time to time. Yet when I go on to my computer tonight nothing I do with my airport or computer will get my webpages to say anything other than "Server not found". I tried turning off my airport then back on and reselecting my network because usually that helps. It would say it connected and I would have full bars but still the same error message. I tried again, and when I did it this time, I did it from within the system/network preferences. When I did this, I watched the connection of my airport go red, then I would connect and it would go to yellow saying I had no IP address.
I would then sit and wait and eventually it would fully connect giving me the green go-a-head. But, again when I would open up my internet, I would get the "Sever not found" message. I would then quit my firefox all together and tried again that way and still same massage. I restarted my computer and tried again...nothing. I became more concerned because my roommate could get on the internet just fine and I could use the wireless in my room through my phone. I was consered that now this was a matter with my computer and not just the internet, so to make sure I got out my ethernet cable and hooked it up with my connection in my room.

I have been experiencing severe drops of my internet connection in OSX. I have tried different routers and multiple computers in the house but it's clearly my MBP that randomly looses its internet connection (WLAN stays connected). It's getting really frustrating. Is anyone else experiencing similar issues?
