Connecting laptops to wireless APs using RADIUS 802.1x and certificates set-up questions

I am working at a small school with 25 laptops for a mobile cart. We upgraded to new dual radio APs and I want to set up the laptops to connect to the APs and validate user credentials at logon. The person before me made a generic username "Student"
on each laptop locally so they could start the laptop and then connect to the wireless with a password. This is less than ideal for many reasons.
I have configured NPS on the server and on the AP. When I login locally and then select the AP I am prompted for credentials and can log in. On NPS's eventlog I can see it granting full access. At that point I do not have internet access which is going to
be a vendor call. I can ping 8.8.8.8 successfully but not the local.domain.org address, nor the server ip 192.168.25.5 which is also the DNS Server. I am thinking that there is a NAT issue there.
When I try to login to the laptops with my AD credentials it is not connected to the AP yet and tells me there is no logon server available.
Is that where the certificates should be used at computer/machine level?
I want to get this setup correctly so anyone who has done this and has some advice for best practice would be greatly appreciated!

Hi,
According your description, we can ping 8.8.8.8 successfully. It means that we have connected to the network.
Due to we can't resolve the domain name, it should be a DNS issue. As you have mentioned, the DNS server is unavailable. Please check if there is something wrong with the DNS server.
If we want client to connect to AP before implement AD authentication, we need to enable single sign on. For detailed information, please refer to the link below,

Hello I recently downloaded an app on my iphone 4s - Remote mouse- so i can control my laptop that is connected to my tv, it used to work fine and now the connection fails, I downloaded another app and the same problem occurs, its not the firewall

Hello I recently downloaded an app on my iphone 4s - Remote mouse- so i can control my laptop that is connected to my tv, it used to work fine and now the connection fails, I downloaded another app and the same problem occurs, its not the firewall and both phone and laptop are conected to the same wifi, i also tried to connect it manually with the ip address and still no connection, can you help??

Close all open apps by double-tapping the home button, then swiping up and off the screen with the app window (not the smaller icon).
Then reset: hold down the home button along with the sleep/wake button until you see the apple, then let go.(No data loss) Try it again.

Josejanko,
You don't supply much info other than your machine is old, so here is some info for you to check thru.
Before doing anything you should have a back up, preferably 2, in the event something goes wrong.
You would have to start by upgrading to Snow Leopard, you would need to buy the disk for about $20 here http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
Check the the requirements to see if your machine meets them.
You would then need to run the 10.6.8 v1.1 combo update to get it to 10.6.8 Mac OS X 10.6.8 Update Combo v1.1
You can then access the APP STORE and possibly upgrade to to further OSX.
You may have applications that will not be compatible with any thing past Snow Leopard, you can check those here Upgrading to 10.7 and above, don't forget Rosetta!
http://roaringapps.com/apps
Office 2008 will not work with anything newer than Snow Leopard for an wxample
You may be able to upgrade to Lion or MT Lion or Yosemite, depending on your machine, from the APP STORE.
OS X Lion - Technical Specifications Lion
http://store.apple.com/us/product/D6377Z/A/os-x-mountain-lion Mountain Lion

Hope this helps you

TS1398 have been connected to my wireless network using a netgear sky broadband router succesfully for a few weeks, suddenly can't connect, network is showing but no signal - all other wireless gadgets are connected just fine - including iphone - any idea

my ipad 4 has been connected to my wireless network using a netgear sky broadband router succesfully for a few weeks, suddenly can't connect, network is showing but no signal - all other wireless gadgets are connected just fine - including iphone - any ideas?

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Can't connect Airport Express wirelessly to network so that AirTunes and internet are available simultaneously

I can't connect Airport Express wirelessly to network so that AirTunes and internet are available simultaneously. My old AE allowed this but can't make the new one work that way.

In your instructions, you say to use the same encryption type as the router has set up. well, I am using the WEP 64 bit encryption and the Airport Utility does not have this...it has 40 bit. Is this a problem, or do I have to be using a the same type of encrytion ?
WEP is available in either 40 or 104-bit, but is usually "advertised" as either 64- or 128-bit respectively. For example, 64-bit WEP uses a 40 bit key (also known as WEP-40), which is concatenated with a 24-bit initialization vector (IV) to form the 64-bit RC4 traffic key. So, WEP 64 on the Linksys & 40-bit is equivalent.
What concerns me more is the loss of bandwidth performance you are experiencing when connecting the AX. When the AX is configured as a wireless client it is acting just like any other wireless devices (computer, laptop, printer, etc.) and not like another router. This should cause little or no bandwidth loss. True the more secure the wireless encryption used WPA2 vs. WEP, the more overhead is required for security, but the differences you are seeing seem excessive.
It is very possible that you may have some form of Wi-Fi interference in the immediate area that is preventing your Linksys from providing a good clean signal.
I suggest you perform a simple site survey, using utilities like the following to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible:
For Macs:
o MacStumbler
o iStumbler, or
For PCs:
o NetStumbler

I have a new MAcBook Air and my photos don't fit on the internal hard drive. I want to store my photos on an external hard drive which I will connect to my Air when using Iphoto. How do I set an external hard drive as the default drive?

I have a new MAcBook Air and my photos don't fit on the internal hard drive. I want to store my photos on an external hard drive which I will connect to my Air when using Iphoto. How do I set an external hard drive as the default drive in Iphoto?

Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

Trouble connecting laptop to wireless

I have a wag54gs installed and a wireless adaptor on main pc. Had trouble with security and could only use laptop wireless with security dissabled. Ive had some help regarding security its all set up again and wireless is working on main pc. Laptop however wont connect now on wireless, says aquiring address or limited /no connectivity but works fine if i attach the ethernet cable and use security. Tried checking setting are the same but must be missing something., probably something simple. Any help would be appreciate.

OPEN YOUR VIEW WIRELESS NETWORKS , YOU SHOULD BE ABLE TO SEE YOUR WIRELESS CONNECTION DISCONNECT IT AND RECONNECT! YOUR ROUTER MIGHT BE WEP ENCYPTED SO YOU WILL NEED YOUR KEY1 THAT YOU CAN FIND ON THE ROUTER INFO, BY TYPING : 192.168.1.1 ON YOUR INTERNET WEB BROWSER!

Problem connecting laptop to wireless network

Greetings.
I recently installed ArchLinux on my asus N80Vb laptop. I downloaded the .iso for the core installation and burn a CD which I used to install. Checksums were a match. I followed instructions on the installation guide and everything seems to have been a success. I installed all packages which seemed to have anything to
do with wireless networking.
The only problem is that I am having difficulty getting my laptop to connect to the wireless network in the house.
The network wireless interface in the laptop is an Intel WiFi Link 5100. I am assuming the driver is loading properly: output from dmesg | tail is:
iwlagn 0000:03:00.0: Unable to find TIM Element in beacon
wlan0: Selected IBSS BSSID 2e:xx:xx:xx:xx:xx based on configured SSID
iwlagn 0000:03:00.0: Unable to find TIM Element in beacon
(the x's in the second line are because I wasn't sure if it was a good idea to post the actual numbers).
I followed the manual wireless setup process <a href="https://wiki.archlinux.org/index.php/Wireless_Setup#Part_II:_Wireless_management">here</a> to try to establish a connection and couldn't connect: trying to ping www.google.com gave an unknown host error.
I have netcfg and created a configuration file with the following:
CONNECTION='wireless'
DESCRIPTION='wireless internet connection
INTERFACE='wlan0'
SCAN='yes'
SECURITY='none'
ESSID='mynetwork'
IP='dhcp'
CHANNEL='6'
When trying to use netcfg I get "Wireless network "mynetwork" not present. [FAIL]
Using iwlist doesn't show <i>mynetwork</i> either, but I know its there because all the PCs, a wii and another laptop are all connected to it without any problems.
(I added CHANNEL='6' because my PC running Fedora shows that it is connected to mynetwork on channel 6, so I thought maybe...).
Connecting via a wired connection is also a possibility but would prefer not to.
Any suggestions?
Regards,
Topaz

Connect to Existing Wireless Network Using Airport Express?

I would like to use my airport express to connect to an existing wireless network set up in my apartment. The wireless router (linksys) is set up in my roommate's room to his desktop. I have a printer in my room and would like to use the airport express to connect to this existing network so that my roommates and i can print wirelessly. I need to keep the printer in my room.
Is there a way to do this? Please advise.
Thanks.

Is the LinkSys a WRT54G? If so, you have two options. If not, only the first option below is available to you:
1. You can configure the Express to connect as a wireless client. You won't be able to connect wirelessly directly to the Express in this mode; you have to connect through the router.
2. With the proper firmware in the WRT54G, you can set up a Wireless Distribution System (WDS). In this configuration, not only can the Express be used for printing and AirTunes, but it will also extend the range of your wireless network.

How to connect laptop to router by using udp receiver

I try to communicate between computer and laptop via router. Computer connect to router by wire. laptop have Wireless Mini Card. I open udp receiver to connect to router. How to connect to router ? what is net address number ? and what is port number ? how to find them ?

You can only connect to a router port if the router is running a service that
Allows you to do so. What kind of connections are you trying to do?
The net address is the ip address in u32.
The port is determined by the service you want to access.
What do you actually want to do with all this?
We need much more info. Router model?
LabVIEW Champion . Do more with less code and in less time .

Can't connect to home wireless network using WPA2

Using PowerPC 10.4 Tiger.
Wireless is detected by airport card with pw prompt as WEP, but the network actually uses WPA2. Enter PW in prompt, but, of course, it was rejected.
My iPhone can get into my WiFI with WPA2 just fine.
What gives?
When network is configured for WEP, I can log in just fine, but can't take advantage of 802.11n (pre)

To use WPA2 requires an Airport Extreme card.
Run Apple System Profiler and under "Network" select "Airport Card" and it will tell you what type of Airport Card you have. If you don't have an Airport Extreme, you can't use WPA2.
Also, even if you have Airport Extreme cards in your computers, you may need to install extra software to enable use with 802.11n as described in this link

Unable to connect laptop to wireless network

My MacBook Pro will not connect to my wireless network, but my iPad does so I know it must be a problem with my computer rather than the network. Any suggestions?
I'm not sure if there is some obscure setting that I need to change.

Give us more information, please.
Is your wireless network supplied by your ISP, your landlord, your own router, or something else?
What can you tell us about the settings on your wireless network? (Not the passwords.)
Did this ever work, or is this the first time you have tried to connect the MBP to this wireless network?
What model/year MBP is this? It has to be somewhat old if it is running Snow Leopard (10.6.8) as per your profile.
