5 Apple machines don't see each other with Bluetooth

I was hoping to use my keyboard with my iPad in the garden today, but they didn't connect.
To try and find out which machine is faulty I brought in all our Apple's with bluetooth: my iPad1, an iPad2, my iPhone 4, an iPhone 4S (all with the latest software) and my keyboard.
To my surprise each and everyone failed to see another machine.
'Searching' was the message on all the displays, and after some 10 minutes I gave up.
Anyone any idea what might be wrong here? I don't understand any of this.

Well, I wouldn't expect the iOS devices to see each other over BT, unless you were going through the Personal Hotspot feature. Those devices don't connect to each other over BT for any other purposes except tethering. You can connect them over BT from within certain apps for specific purposes such as transferring photos but, again, the connection is done from within the app.
So, the only real issue here is why the keyboard won't connect to the iPad. Is the keyboard currently connected to another device such as your computer? If so, disconnect it.

I'd like to connect my ipod touch (3rd generation) to my ipad2, but I don't see each other through bluetooth. What should I do?

Hi,
I am trying to connect an iPod touch 3rd (ios 5.1.1) generation to control my KEYNOTE's presentations in my iPad2 (ios 6.1.3). I activated bluetooth in both but they do not see each other. Is there any specific procedure to allow the connection or it is a problem of compatibility between versions of ios?
I appreciate any input.

iPhone: Go to Settings > General > Bluetooth and turn Bluetooth ON.
iPad: Go to Settings > General > Bluetooth and turn Bluetooth.
On the iPad running Keynote, open your Keynote presentation.
Tap the Tools icon in the toolbar.
In the Tools menu, tap Settings.
In the Settings menu, tap Remote.
In the Remote Settings menu, turn on Enable Remotes.
On the iPhone, open the Keynote Remote app.
In the iPhone Settings window, tap New Keynote Link.
On the iPad, the name of the iPhone appears in the Remote Settings window; tap Link.
On the iPad, enter the four digit number that is displayed on the iPhone, and then tap Done.
iPhone: Open the Keynote Remote app. You can begin to control your slideshow from your iPhone by tapping Play Slideshow.

Windows 7 computer, and my macbook pro on snow leopard don't see each other?

My windows 7 computer, and my macbook pro on snow leopard don't see each other. I have configured the windows section under the network prefrences with the required information, and still no luck. Does anyone have any sugestions for me?

Shouldn't they see each other and let me use each of their files?
Please pardon the obvious here, but have you checked to make sure that you have enabled the File Sharing option on both computers? You may have already done this, but your post did not mention this, so we can only go with the info that we have.
If you have not enabled File Sharing, I can't help on Windows, but on your Mac...
Open System Preferences (gear icon on the dock)
Open Sharing
Enter a check mark next to File Sharing
I imagine that there is a similar setting for the Windows machine
It would be a good idea to power cycle your entire network as well to make sure that the network is sequenced correctly. Power everything down, order is not important.
Start your modem first and let it run a moment by itself
Then start your main router the same way
Continue starting each device the same way until everything is powered back up

Applets don't see each other when having certain jar files as archive

Hi,
I have read a nice solution for Applet2Applet communication when they are on different html pages (different frames or windows) at http://www.javaworld.com/javaworld/javatips/jw-javatip101.html.
They see each other through a static AppletManager.The idea is working it is really good.
But when I add a certain jar file to the archive parameter they don't see each other any more. Even more the static initializer of the AppletManager class runs twice. I have also noticed that the ClassLoader of the two applet is different:
LeftApplet: ClassLoader: sun.plugin.security.PluginClassLoader@10a6ae2
RightApplet: ClassLoader: sun.plugin.security.PluginClassLoader@13adc56
If I remove that particular jar from the archive parameter they are the same:
LeftApplet: ClassLoader: sun.plugin.security.PluginClassLoader@13adc56
RightApplet: ClassLoader: sun.plugin.security.PluginClassLoader@13adc56
and the two applets can communicate again.
And here comes the fun the two applet doesn't use anything from that jar package...
I would appreciate any help, or link where I could go on whit this issue.
Attila

If the jar lists are not identical in each Applet, different classloaders are used:
archive = "a.jar,b.jar,c.jar" in Applet A, means that in Applet B you must have archive = "a.jar,b.jar,c.jar" or a separate class loader will be used. Do this even if your applets don't use any classes in an included jar.

Can get onto Internet but Computers don't see each other

I've got my Linksys connected via ethernet to a desktop - using DSL. Security enabled. Had my network set up fine - a wireless laptop sees the intenet connection and the computers saw each other fine (shared disks, etc.)... Today, my DSL went down for a bit - I jumped onto my neighbor's open wireless. My DSL came back up. THe desktop and laptop both see the internet. But they don't see each other any more. I've run those stupid wizards ten times. I've tried creating a new workgroup. They can ping each other. I don't get it. HELP!

When changing settings for file/printer sharing on Windows it is always necessary to be patient. The whole workgroup browsing concept of windows requires some time to be up to date. I suggest you run the sharing wizard ones and follow the instructions there exactly.
Also try to ping the other computers to see if anything goes through.
As you have "jumped" to your neighbor's network for a moment also make sure you connect to the correct network. Better remove the neighbor's network from your list of preferred networks. Else you end up there accidentally.
Therefore, you should better setup the sharing while all computers are wired to the router.
Another possible cause could be the firewall on the computer. Make sure to turn it off to see if it is the problem. Most software firewalls (except the windows firewall) react very sensitive when you just 'jump' to another network and tend to block all traffic by default.Message Edited by gv on 02-09-200701:58 PM

Mac and iPhone don't see each other

This isn't just with Home Sharing, but with other apps that use wifi to connect, specifically iAccounts and iBackup, but I couldn't find a more appropriate community.
My iPhone and MacBook Pro are connected to the same wifi network, one has 192.168.1.64, the other is 192.168.1.65, both can connect to the internet with no problems, both have full signal strength. So why can't they see each other? Sometimes it works, when everything is turned off then back on again, but sometimes that doesn't work. Last time it worked only after I reset my router, which suggests maybe the router is the problem. It's a BT HomeHub 3, which probably doesn't mean much to most of you, so give me general advice. What settings should I look at? Could it have something to do with my Mac connecting via 802.11 N and my iPhone 802.11 G? It's a 3GS, so it can't do N.
Both Mac and iPhone have the latest OS (10.6.8 and 4.3.3).

I stumbled upon the answer by searching other (non-apple support) sites for this problem. Apparently (and non-intuitively), "personal hotspot" (aka internet tethering) must first be enabled before attempting to establish a BT link. The reason I say non-intuitive is:
Firstly, bluetooth is supposed to be a stand-alone wireless networking protocol that doesn't require another wireless network to be available for it to work. What other sort of device (computer or otherwise) requires an existing network to be in place before BT will work?
Secondly, if tethering via personal hotspot is a prerequisite for a BT link, why is there no pop-up message advising of this when BT is turned on? Something like "Hey idiot, you need to turn on personal hotspot before you can establish a bluetooth link!" Or better yet, why not automatically turn on the hotspot when the BT button is switched on?
Thirdly, it really makes the BT shortcut button (in the home screen control center) worthless if you've still got to manually drill down into the settings menu to turn on hotspot anyway.
I scrubbed all apple user support articles related to using BT and pairing the iPhone with iPad that I could find to make sure I hadn't missed this new requirement somewhere - and I don't see it mentioned anywhere (although I'll admit that steam was coming out of my ears while I read it, so I may not have been in the best frame of mind to catch any new information). In the BT troubleshooting article, it mentions every check-this and check-that step but nowhere does it say make sure that personal hotspot is also turned on! I submitted feedback at the bottom of the article; hopefully they'll update it.
Thanks, Lyssa for bearing with me through all of this, which in the end turned out to be a user error. Although I consign myself to some comfort in knowing that this is not how it worked prior to iOS8. And as soon as I can find a phone on iOS7 or older, I'll confirm that.

"Buddies" Don't See Each Other

I'm attempting to help two relatives use iChat to talk to each other. Both are using the latest version of Tiger, one on a iMac with Road Runner cable internet and the other on a Mac Mini with SBC/Yahoo DSL internet. Both are directly connected to their respective modems with apple firewall turned off. Both can get online, signin to ichat using their AIM or .mac accounts and see other people. But, even though they are online and signed into ichat at the same time they do not see each other even though I created the proper buddies on each computer. I've went round and round for over 2 hrs and just can not figure out why they can see a third party (my own aim acct that I had signed in on my own computer), but not each other.

Hi Russell,
It was clear enough.

E4200 - PCs don't see each other and printer on USB port not working

I been around tech all my life. Acquired by MS when they had only 2000 employees. I don't get excited about tech. Its a tool to help you do something better, excluding games. I had the linksys wrt54... with booster antennas. Worked great, but could not reach one room, the furthest away. Even though I retired 10 years ago I do some private work for fun. I was required to change from 16bit WEP to WPA. My WRT54 just missed the cut off so I went and bought the best home product they had;
*I have 8 computers and connecting them was time consuming *The computers with same settings don't all see each other. The printer port USB off the hub is a great idea if it worked. They have an upgrade to fix this but ever time I try to install the firmware it fails.
This product has...

Short range
Reliable connection

In reference to the issue that you are facing I would like to recommend you few things.
For computers to see each other on the network and to share information they have to be in the same work group, file sharing should be enabled on all the computers and they have to be in the same network. If you are still facing issues, try to disable the firewall on the computers.
As far as your printer is concerned, I would like to know whether you are trying to install the printer with the help of cisco connect, if yes, then please try to upgrade the latest version of cisco connect and then follow the link below.

Computers don't see each other on home network.

Recently set-up a wireless network. Using a linksys wrt54gs. A DSL modem is tied into this and desktop is hard wired into router. I also have two other laptops using the router wirelessly. The problem: All computers see the router and connect to the internet, but I can't seem to get them to see each other for file sharing and printer sharing from desktop. My wireless network has a name, and the workgroup for each computer a different name from the wireless network, but all the same.
Desktop is XP, (1) laptop is NT, and the other is Vista.
I not a PC guru and probably a liitle over my head so any help would be greatly appreciated.

I went home that night and done the same with AVG antivirus. Can't believe it was as simple as that.
configure your antivirus software like AVG or Norton to allow file and printer sharing as well as allowing your windows firewall to do the same.
Mine was in AVG firewall > settings (or Configure) > system > file and printer sharing......................just click on the dropdown box to allow.
As soon as I done this I went to my network places and the network files were visable.
other settings in there also solved my remote desktop problems.
Why couldn't I have thought of this 6 months ago.

Two Macs don't see each other

Just bought a new Macbook and it's on the same subnet as my iMac. I have the firewall running in stealth mode on both machines. Neither one sees the other and Finder sidebar does not show any "shared" computers.
I'm assuming that I need to disable the firewalls for these two machines to see each other.
The question is: Once these two machines have located each other, will turning on the firewall in stealth mode shut down the sharing once more, or will it stay active?

Got it working. Disabled the firewalls, set up the sharing, set up the user accounts (different user names on different machines thanks to the Migration Assistant) and away it went. Re-established the firewalls and everything is cool.
Interesting how working on Macs changes ones thinking. I've become so used to everything just working well that I just slap things together without any advanced thinking -- on occasion that bites back. It didn't help that from a security standpoint, I had tightened down every nut I could find. If these had been Windows machines, I would've planned much more thoroughly and would have expected and anticipated trouble at every step of the way.
Thanks

Two Computers on Router; Don't See Each Other

Two computers, each connected wirelessly to same FiOS router. Each connects perfectly to the Internet, but cannot see each other (ping test).
Normal? Some little change in firewall setting needed?
HaroldWho

Whoops. I forgot that in addition to the router firewall I had my own rules via 'iptables,' that dropped all NEW connections. I just needed to allow connections from 192.168.1.0/3

My computers don't see each other on the network

my Imac (early'06) and a machine running Ubuntu (apparently a linux platform OS) and a windows machine are connected to the same network thru a router. All machines access the internet fine. However i want to file share with the other computers but they dont show up in my network window.
also when i type their IP addresses into Connect to Server dialogue, I cant connect to them or even see them on a network.
Anybody familiar with setting up cross platform networks?

Has Ubuntu and Windows ever seen each other?
You say "Ubuntu is apparently a linux platform...". not apparently - it IS a linux platform (are these your computers?)
The first thing is to get them all into the same logical Workgroup.
On PC: ControlPanel>System>ComputerName..jot down workgroupName.
On ubuntu, the file/etc/samba/smb.conf is edited (might not need this yet).
On Mac: Utilities> DirectoryAccess, Configure SMB/CFS...enter WorkgroupName in appropriate box.
(then look into SystemPreferences>Sharing, and turn on File Sharing.
In network utilities on the mac, have you been able to you ping these computers by their IP address? Have you been able to ping mac by number from Windows or Linux?
This site might help, too along with the Apple link that the other user posted:

Macbook Pro (2010) and iPad don't see each other on same network

I'm running OSX10.10 on a MacBook Pro 15" mid 2010 and a brand new iPad Air running iOS 8 on the same wifi NETWORK with bluetooth activated (and not) - AND AIRDROP DOES NOT RECOGNIZE EITHER DEVICE!!!!

Please HELP: Homesharing PCs don't see each other, but both are signed in

I just enabled home sharing on both my PCs, one is a windows 7 the other is a windows xp machine.
Both machines now have home sharing turned on.
You can verify it in iTunes by going to Advanced on the menu bar at the top of iTunes, and see that it says "Turn Off Home Sharing (my Account name)". So that's how you know it's turned on with both computers.
But, nothing appears on the left side of iTunes navigation on my new PC. .
It's supposed to show the other PC itunes library once it finds it, and display it under a folder called Shared in the iTunes window, but it is not appearing.
Anyone got any ideas how to solve this one?

PROBLEM SOLVED!
PROBLEM SOLVED!
PROBLEM SOLVED!
SOLVED BY UPGRADING TO THE EXACT SAME AND LATEST iTUNES VERSION ON BOTH PCs, AND RESTARTING iTUNES.
Actually I solved the problem on my own shortly after posting my question last night.
I wanted to make sure I had the latest versions of iTunes on both PCs, and they were both months older iTunes versions, and not the same version on each PC, so I thought maybe I should "align" both iTunes installations up better with the same version.
One PC version of iTunes was 10.4 and the other was who knows what, older I'm sure.
I upgraded both iTunes to be the exact same version 10.6.3, which is the latest version as of today. Then I re-ran both iTunes on both PCs and it is now working like a charm.
What I don't know is if the reason it is now working simply because I restarted iTunes, or because I upgraded both of the PCs to the latest version, or a combo of both reasons. I should have tried just exiting out of itunes then coming back in first before upgrading to see if that was the reason, but no matter, it is working flawlessly now.
Using HomeSharing is THE single best way to copy your iTUNES library from one older PC to your new computer, simply by importing into iTunes on the new PC over the HomeSharing network feature of iTunes. My Nano has 4000 songs so it takes it about 3 hours to do the transfer. It copies the entire iTunes music library onto your new PC without you having to think or figure out where to put the files.
Lots of times on forums I see people recommend things like the firewall or remove and reinstall iTunes, those hardly ever turn out to be the problem. For once I'd like to see people admit that the iTunes program itself on occasion has bugs in it.
One current repeating iTunes bug that frustrates me is in iTunes will not upgrade itself when you tell it to. When you go to Help > Check For Updates , and it comes back and says iTunes updates are available do you want to download it? And you select yes, and it does nothing. This happens on all 3 of my PCs, no error message, it just does nothing.
Apple has had this bug for years and still has not fixed it. All my computers with iTunes have this problem. I always have to bring up a browser and go to Apple to download the iTunes exe and run it because they don't know how to make their own program update itself.
Anyway, my problem with HomeSharing is solved!!

Audigy 2 ZS Platinum- Inspire 4.1 don't see each other after computer move

?? Running: Windows XP Pro
Sound Card: SB Audigy 2 ZS Platinum? Driver Version 2.8
? Speakers: Creative Inspire 4. 4400
? Software: Creative Media Source 3.30
I moved my computer to another room and started having sound problems. I removed Creative Media Source 5 ( I had it when I used the creative zen mp3 player ) because I thought it was redundant on my system. My sound is now hollow and tinny. But the truth is I don't know what caused the problem to begin with since the Holidays were involved and many people were at my computer. I only want the sound to be as great as it was before.
These are my problems:
. No matter how many times I set the audio properties through the volume control icon on the taskbar, the configuration always resets to desktop stereo speakers instead of surround sound.
2. Using the Creative Speaker Settings results in information showing that there are only 2 speakers attached and they are synchronized with control panel. Under speaker calibrator it reads that there is a generic speaker system.
3. Using the calibrator Wizard, only 2 speakers show up.
4. Normally in the EAX console, the Effects tab shows many settings - but now there is nothing inside the box.
5. On the CMSS3D tab, the slider for the speakers is grayed out
6. The THX setup console on the Speaker selection tab there is nothing under the speaker selection tab - There is an analog output and a digital 48khz under digital sampling.
7. Under calibration there are only left and right front speakers the subwoofer and rear speakers are grayed out
This is what I have done to troubleshoot my problems:
. Used Auto update of card which reads that everything is updated. There are no drivers for the speakers, so that is ok.
2. Through the Creative Organizer I enabled CMSS
3. Through the Creative Audio console on the Decoder tab, I have checked use built in decoder and under speaker mapping for 4./5 using side channels
4. Under Dolby digital settings Dynamic Range is Full - Dolby Pro Logic is ON - Dolby Digital EX is ON --- DTS for Es is ON
5. Made certain all connections are secure and verified the placement of the green and black wires coming from the subwoofer are connected to my computer in the correct place, namely that the black wire is in the second hole from the firewire port and the green wire is in the third hole
Please help me if you can. I'm ready to throw in the towel, I would even buy digital speakers but don't know which way to turn. I don't know if it's the card or the speakers or the fact that I removed the Media source 5 (for which I can't find the disk.)
Thanks in advance for reading this and taking the time to troubleshoot with me.
Jane

Hello KokChoy-CL.
Many thanks for your support!
I've been reinstalled the drivers and changed the options of your link, now the DTS 5. effects are quite working on my xbox.
Again, thank you!
Lucio.
