Making Wifi Network Only Available on Certain Computers

My roommate and I have a password-protected wireless network. However, we are pretty sure someone else is able to use our wifi because we can manually check our bandwidth online; when we are out of town, bandwidth is still being used, and I have had more than one person connected to my iTunes before.
My roommate said she's connected to password-protected wireless networks (for which she didn't know the password) before and had no idea how it even worked. But that must be what's happening!
I've heard of wifi networks that only allow certain computers to connect to them. How can I get ours to do that, too?

See if any of this helps.

My router lets me turn on a log file in it that records all traffic through it. Check your routers instructions to do this.

Macbook PRO can't find ANY Wifi network - only at home

Hi, i have a very strange problem with my *Macbook Pro*. I have 3 apple computers at home and one pc. On all machines Wifi works fine, except my new alu Macbook Pro. Important note is, when im with my macbook on other place, office, caffe, *Wifi works fine. But when im at home, this macbook simply can't find ANY network, it's blind.* Interesting thing is, all other computers are several years old and WiFi works fine on them. My friend also bought a brand new macbook pro, and this machine also couldn't fine any network at my home, or in other case when it found networks, it couldn't connect and recieve error message "Connection timed out". I noticed there is new Wifi network in our range, is it possible that this network can cause "blindness" on new macbooks?

*I have to say, I'm really glad you are trying to help guys.*
Well, router is almost on default settings, SSID is brodcasted and i'm not filtering MAC adresses. I tried changed channels, diffrent types of security or no security, no luck.
Guys, maybe i wrote it wrong, but this MacBook can't see ANY network. Around me there are 4-6 other networks which I'm able to see from other machines. So *problem is, this Macbook can't seen ANY network - not just mine.* BUT when i'm with this Macbook in office for example, or any other location, Wifi works....
And one more important thing, this happened suddenly. I was able few months ago to find any WiFi around me with this Macbook. No changes to router, no changes to mac. Problem is somwhere in the middle...try to focus on this: why i'm not able to see any of those cca 6 networks around me. I really think it has to do something with distorted signal and Wifi card used in new macbooks. It's really sick, because all other machines works perfectly (MB 07, MBP 06, PC, iPhone 3g)
I found a log on the router, and it's happening all the time:

WiFi Calling - Only available on iPhones purchased directly form EE

I have been in touch with EE Tech Support as they cannot seem to get WiFi Calling enabled on my iPhone. After more than 5 calls to various levels of Tech Support, today I am told that WiFi Calling on an iPhone 6 is only available if the phone was bought from EE stores or website. I don't believe the support guy and feel like I am being fobbed-off. Anyway, I am writing on this forum to see if anyone else has had this response? I cannot believe that Apple would use this feature in their product launch keynote and then agree with EE that it should only be available to phones bought direct. Doesn't make sense. I'd love to know what you think.

I have been getting the following message on screen, even though I am not trying to send a message or anything: Sorry, the number you are sending to does not contain enough digits. Please check the number and try again. … but I have done a reboot since and it appears to have stopped showing.

T500 running very very slow on specific WIFI network only???

Hi,
This problem is driving me absolutely crazy. It means that I can only use my PC at home if I use a cable connection to the router....
Problem is that on my home network my T500 is having a very very slow access to the internet via wireless. On all other wifi network I have connected to there is no issue and speed is high.
Also several colleagues have been here with their T500 and none of them experience any issues with speed. We all run on the same t500 model, ordered at the same time and with same setup. We use Windows XP.
I have tried to update all drivers, I have called my network provider who have updated router software, changed frequency and all other things they could do to avoid interference etc.
I have two other PC's at home - none of them have any issues.
I have done a web seacrh and could see that I am far from alone with this strange issue of a T500 being slow on only a specific network (often a home network). Many different routers are involved, so I dont think it is arouter problem (would also mean that my colleagues identical t500s would have issues right??).
Have there been any reolution to this T500 problem??
Best regards and with hope of "salvation" :-)

Which model of wireless card are you using? Intel 5100 or 5300 or thinkpad version?

HT4262 My wifi network only works when I am in the same room as the time capsule. The airport relay and time capsule are showing green.

My wifi network is down in the entire house apart from the room where the base station is located. The Time Capsule and Airport Express are green lights. Any suggestions?

Looks like massive interference issues.
Are your walls made out of sheet-rock instead of drywall?
Also if that room is near a washroom or Kitchen, that would explain some things.

Airport only works on certain computers...

I have two APX and two AX. Even if I use just one APX still only my 15in powerbook will have inernet. My other computers (G4 Cube, and two older iBooks) will recognize my network, but in the network status pane in system preferences it registers yellow (may not be able to connect to the internet). Where as on my powerbook it is green.
I am pretty savy with the network and have rebooted and reset the entire thing many of times. What is the problem?

One suggestion could be that somehow the mode has changed from 802.11b/g to just 802.11g. This would stop the older machines using the network, although I do believe that they may still see it.
Applications > Utilities > Airport Admin Utility > Airport Tab > Mode (At the bottom)
Make sure that the mode is set to 802.11 b/g compatible.

Why are certain apps only available in certain cou...

There's a Dutch news app for the Nu.nl site. I would like to download this app, but this is not possible outside of the Netherlands (which is where I live). Why on earth is this so? Can't a person abroad read the Dutch news? I've contacted the publisher of the app and asked them why they only made it available in the Netherlands. Their reply was that this was a restriction of the Ovi store. They would like to see it available elsewhere as well.
This is unfortunately just one example of many. Ovi Store can you pleas do something about this?

Making checkboxes checked only when a certain value is true

I am trying to make a checkbox dynamically check itself. I only want the checkbox to be marked if a value is true. I am using JSP
here is what my code looks like.
<input type="checkbox" name = "Full1" value ="0">
<input type="checkbox" name = "ReadWrite1" value ="1">
<input type="checkbox" name = "Read1" value ="2">
<input type="checkbox" name = "Delete" value ="0">
say that my variable is
var = 0;
I want to to do something like this
if(var=0)
<input type="checkbox" checked name = "Full1" value ="0">
else
<input type="checkbox" name = "Full1" value ="0">

Guys, he said he was using jsp.
So Scooter, assuming that's what you meant (and not client-side javascript), you could achieve this effect with:
<% if (var == 0) { %>
<input type="checkbox" checked name="Full1" value="0">
<% } else { %>
<input type="checkbox" name="Full1" value ="0">
<% } %>

No Wifi Networks after Sleep

I'm running Mavrics for a while and all has been good. But lately after long sleep on my Macbook Pro (17" early 11) no wifi networks are available on the interface list. When I restart, they re-appear (most of the time).
I've tried creating a new network location, turned wifi on and off, even deleated the preferences in the library, but no luck.
I'm an engineer and this has got me stumped.
Thanks in advance!

To see if you computer even needs this fix, I would suggest you click on Software Update...
It will show up in Software Update if your computer fits the specs for the update.
The Software Update version is only 1.3 MB
The other download directly from Apple is 25.81 MB
big difference even if a person has 3 to 5 computers the Software Update will take less time.

Airport Extreme green light but can't see the wifi network

Hello, coming back from the holidays I can't see my Wifi network anymore (From PS3, Phone, Computers ..etc.). My airport has a greenlight and the internet is working fine if my computer is connected with an Ethernet cable. I re-did the configuration many times and I did a hard reset of both my modem and the airport. It is not setted to a hidden connection. All the settings are basic like before. The only difference is that I did the update to 7.6.4.

I think you were right, my airport was broken and I noticed that at the end of the configuration process where there's a green checkmark it was written in the bottom that a wifi device wasn't working properly. Nothing could be done to make it work though.
I bought a new Airport Express now but I still have a major problem. I was able to configure it through wifi with my iMac without any problem and now it is connected to the internet via wifi perfectly but i STILL can't see the network with either my Android phone or my PS3 console !?
- Brand new airport express
- configured to "create a wifi network" with a WPA2 password using the simple steps of the airport utility
- Airport Utility 5.6.1
I did reset the airport express a few times with the utility and by removing the power cord. I also did reset my iMac and I can still connect to the wifi just fine with it.

Mac NOT automatically connecting to preferred wifi network

Hi,
I am facing a problem with OS X 10.9.1 (Mavericks) wifi connection.
I use a Time Capsule as a base station and 13" Macbook Air (2012). The base station is connected to the internet through a PPOE connection.
Here are the details.
Since upgrading to OS X 10.9.1, my Mac automatically connects to preferred wifi network ONLY WHEN the wifi is available at start up or when the Mac wakes up from sleep, but NOT OTHERWISE.
Before the upgrade, the Mac automatically connected to the preferred wifi network not just at start up, but whenever the wifi became available.
In other words, after the upgrade, if I boot up the Time Capsule base station and the Mac simultaneously, the Mac scans for the base station wifi network (this is configured as the top preferred wifi network) at start up, but since the base staion is still booting up, the Mac doesn't find the wifi.
But once the base station has booted up and wifi is available, the Mac no longer bothers to join it. At this point, the Mac is also not able to do Time Machine backups to the Time Capsule because it is not able to locate the Time capsule disk over the wifi.
This situation remains (i.e., the Mac being not connected to the wifi) unless I do ONE of the following:
1. I manually select the preferred wifi network using the wifi icon at the top of the screen; OR
2. I put the Mac to sleep (by closing the cover) and then wake it up. On wake up, it connects automatically to the preferred wifi network; OR
3. I turn of the wifi (using the wifi icon on the top) and turn it back on, at which point, the Mac automatically connects to the preferred wifi network.
I have tried everything possible including contacting Apple support, but so far the issue is unresolved.
Appreciate any help you can provide.
Prem

I have had wireless problems intermittently for a year, and seriously for 6 weeks. Apple denied the issue and was no help in spite of many tens of thousands of people on their own discussions complaining. I found a post suggesting a couple of things which fixed the problem. I don't know if both are necessary, but the first by itself does not solve the problem.
Lock the channel of your router to channel 1, apparently Apple and 802.11n don't play well together on higher channels. When this becomes a standard this will be resolved I hope.
Open your network preferences, select 'airport' and advanced. Delete unused networks. Select your network.
Open TCP/IP and write down all the settings, configure iPv4 manually. Enter the settings manually. Turn off IpV6.
Open DNS and write down your DNS server. Delete it and re-enter it manually.
This has worked on 2 macbooks and an iMac for the last 3 weeks with no network drops.

Cannot recognize wifi networks

My laptop is hardwired to a wi-fi network and works fine. However, when I take it elsewhere, it does not recognize any wireless networks - including the hard-wired one -- other devises and computers recognize it fine, so it must be the laptop. If anyone could direct me to what to do, I'd appreciate it.

You cannot hardwire to a wifi network, only the ethernet can be hardwired. If you cannot connect to any wifi your adapter may be turned off or it's possible you don't have wifi installed. Is the wifi icon lit? switch on? press FN+F5 and see if it reports as being on.

WiFi Networks and an iPod Touch.

I have seen many comments about WiFi networks and the seemingly impossibility of the iPod to connect to some.
However, I have not come across a solution to my issue - there may have been one but I confess I've not been successful at finding it!
I have set up a home network. At first I used an Airport Extreme but then it died so I set things up with a NetGear DG834GT. The home network uses a WPA2 password.
At home no problem - my MacBook Pro (Core2Duo), my son's iMac i7, my 2nd Gen iPod Touch (4.2.1) and my iPad 2 all connect great to the WiFi network. I can surf the web etc etc. I'm a happy bunny.
When I'm out and about I often use my iPod Touch to get access to the web and my e-mails etc using WiFi. Most networks are secured meaning you have to type in a password. Hotels are like this and usually there is no problem once the front desk gives me the password. The unsecured ones are often WiFi Zone Hotspots where you have to pay to continue. I don't usually bother with these.
Some sites though offer unsecured, free access and free internet use - coffee shops in particular. A coffee shop near me has such a network and I have absolutely no problem connecting. However, I have come across a few networks which show up in the "Available Networks" list complete with name etc. And yet when you select this network and try to join I get the message "Unable to join such and such Network. Obvioulsy with no network connection there is no internet etc.
Usually I simply ignore this problem and wait until the next WiFi network is available (when I get home?). Not quite so reliable if home is 3000 miles away!
But does anyone know why there are some networks that I cannot join? Is there a solution for this that I can carry out? I've tried the usual things like resetting the iPod, forgetting the network etc. Obviously I do not have access to the router as this is owned and operated by the company/enterprise concerned.
Not a show stopper by any means but an irritation nevertheless. Incidentally, there were also a few networks recently on my travels where both the Touch and the iPad behaved the same. i.e. I couldn't join some networks with either device.
Thoughts?

Interesting hypothesis B-rock. I could try contacting the network administrator but my guess is that I'll be met with a blank look when I ask for that! Still can't be bad to try!
Another piece of "anecdotal" evidence for you. At the local garden centre (which is part of a chain) I used to be able to connect - no problem. Then suddenly all connections failed - at all locations. I am leaning towards believing that they have changed routers to more "modern" ones and for some reason these new routers won't allow connection to an iPod/iPad etc. As yet I cannot confirm this or otherwise and unless someone comes up with a bright idea I'm left with the feeling that unless the network administrator recognises that he/she needs to create a network that works with iPads/iPhones etc we're doomed. I noticed that the next table over using a PC had no problems! Grrrr.

When i get close to my modem i have wifi network but when i get to my room i can't get any wifi network

my ipad can get any wifi network only when i'm too close to my modem.

You need one of the following:
1. Wireless extender
2. Wireless repeater
3. HomePlug wireless extender
