I cannot set up an ad hoc network

I cannot set up an ad hoc network using my macbook pro running10.7.4 I'm not trying to use the internet or share files. I'm trying to use my iPad as a second monitor using Air Display. I get a "Connection Failed" message.

I have hit or miss problems (a LOT of misses) with HP printers and Macs for years and so have my clients. I'm here right now because I can't even share an HP Photosmart 8250 from one Mac to another right now.
It's very frustrating. I wish I had better advice, but when it comes to HP printer and using the Mac's built-in printer sharing it just won't work sometimes. I'm not sure if I hate Apple or HP more for this or not.

Having trouble setting up an Ad Hoc network with both iOS, Mac OS, and Windows.

So I'm skiing with some friends but we forgot to bring a router with us. The lodge internet is passable but we only have one ethernet connection. My friend connected his (windows) laptop to the ethernet and set up an Ad-Hoc network. The problem is that only Mac OS and iOS devices are able to connect to the network and use the internet. The windows machines and Droid devices can't connect or in some cases they can connect they can't use the internet.
My question is what special wizardry allows Mac OS and iOS to work fine on the ad hoc network but not the other platforms? Is there something I can do to get the other machines to connect to the network? Would things work better if I hosted the Ad Hoc network? Thanks for all the help.

Hi Munkiez, and a warm welcome to the forums!
See if this helps about halfway down is Wifi/Airport.

Using Airport Express to set up an ad hoc network for presentations

I have to give a presentation where I will both need my MacBook Pro and iPad. I may or may not have a wireless network available (will depend on location). Is there a way that I can use an Airport Express to set up an ad hoc network and use an Apple TV for AirPlay from my iPad and laptop?

Easy to do. Just set up the AirPort Express to "Create a wireless network".
When you see the "error" message(s) that there is not an Ethernet cable plugged into the WAN port and/or no Internet connection, click "ignore" and you will have a green light on the Express.
Wireless devices will connect to the network by selecting it and entering the password.

Cannot set Airport Extreme to Extend Network

Hi all,
So I have a Time Capsule 2013 downstairs as my main base station, two other Expresses downstairs set to extend the network, and one Airport Extreme upstairs which I can't set to extend the network. During the setup in Airport Utility, it allows me to select "Extend Network (Recommended)" and the Time Capsule as the main base station that it would be extending. But when I check it in Airport Utility after it's set up, it shows it set to "Create a Wireless Network"
I have ethernet connected to the upstairs Extreme via a wall drop going straight to my FIOS router in a distribution panel. My main Time Capsule is also ethernet connected the same way going to the FIOS router.
So my question is... is the Extreme upstairs changing back to "Create a Wireless Network" because it is ethernet connected, unlike my two Express units downstairs? And secondly, is this the preferred method to set up my network? (basically, a Time Capsule and Airport Extreme each connected to a LAN port on my FIOS router, plus two Express units on wireless.). I've read where the optimal way is to interconnect the Airport devices over ethernet, but my distances are too great to do that.
Any feedback or advise would be much appreciated.
Thanks

is the Extreme upstairs changing back to "Create a Wireless Network" because it is ethernet connected
Yes. This is the correct setting.
It can be confusing, but when you "extend" using an Ethernet connection, the AirPort will use the "Create a wireless network" setting.
When you "extend" wirelessly, the AirPort will use the "Extend a wireless network" setting.
If you try to connect using Ethernet, and use the "Extend a wireless network" setting, the "extended" network will crash.
is this the preferred method to set up my network?
A wired Ethernet connection is always preferred over a wireless connection when you are extending the network. The main reason for this is that there is no bandwidth loss in a wire.
When you "extend" wirelessly, the extending device can only extend or repeat the bandwidth that it receives. By the time that the wireless signal reaches the extending device, it has slowed down considerably. So, a slower signal gets repeated.

Ad hoc network for Airplay Mirroring

Can you create an ad hoc network between an Apple TV and a MacbookPro to use air play mirroring? It would be useful when there is no available wireless network?

Hey, thanks for reading my problem!
The vista PC has the internet in to it... cable modem with ethernet wire to NIC.
Auto addressing through virgin media.
Same PC with a second nic with manual addressing.
192.168.0.1

I also manually put the dns server address in here from virgin.
This nic connects to my 1gb hub.
laptop using win XP connects to this hub using nic and wire using a manual address

i have tried setting the dns and allowing it to be auto but neither makes a difference.
create ad hoc connection on the laptop
shared authentication
WEP encryption with network key i typed in

advanced setting computer - computer ad hoc network only.
Does this sound about right?
If i'm totally off then feel free to laugh LOL!
i then set my touch manually
ip address 192.168.0.4
submask 255.255.255.0
router 192.168.0.1 (vista gateway ip address)
is this wrong?
Just to clarify, I do not have a router... it's a cable modem connected via a wire to my hub which is a stand alone hub that has no features. The only wireless thing i have is my built in laptop wireless chip that i created the ad hoc connection with.

Ad hoc network with Non-airport adapter

I'd like to be able to set up an ad hoc network to communicate between my PowerMac G5 and an iPod touch. My mac does not have an airport card. I have an ASUS wireless usb adapter. I know this works because I can communicate with my wife's iMac if I create a network on her machine (it has airport built-in). I can't see any way to create a network on my machine, as there is no airport available in Network settings. Is there a way to create an ad hoc network using a 3rd-party USB adapter?
Thanks for any help.

Hi there,
Did you ever resolve this? I am in the exact situation. Thanks for any tips.

Ad hoc network with airport extreme

Hi,
i have no problem setting up an ad hoc network for my canon dslr to wirelessly download images to my MBP after each shot is taken.
however, i would like to extend the range of this ad hoc network as i want to be able to shoot in another room. can i use the airport extreme to accomplish this?
if this is possible, may I know how to do it?
i do not need internet, so this airport extreme just needs to help me extend the range of my current ad hoc network.
Thank you very much in advance.

hi,
is my question too vague?
do let me know what other info do i need to provide?
Thanks again
appreciate any help.

Ad hoc network for ipod touch

I know there's several posts about this but non are specific to my setup so I though I would create my own thread.
My setup
I have a pc running vista 32 bit and I use this as my server. My internet connection goes through this pc and i shared amonst 3 other pcs. This pc has 2 NIC's, 1 for the internet/modem and is shared, the other to connect to my 1gb hub. I do not have a router, I have the net shared through the server pc then on to a hub which the other pcs are connected too. I have assigned static ips to the network computers and all manage to get on the net.
My laptop (win XP Pro) which is one of the computers connected to this hub also has built in wireless and I would like to know how I can use this wireless feature to get my ipod touch online as well.
The laptop is on the net using the NIC and everything is fine. For the wireless connection I setup an ad hoc connection and it's showing up in the wireless network connections in XP on the same laptop so that's running correctly. My ipod finds this wifi and does connect, however i can not browse the net using it. It keeps saying Safari can not find the server.
server pc wired - ip 192.168.0.1
laptop wired - ip 192.168.0.2
laptop wireless - ip 192.168.0.3
I have tried the following settings in my ipod wifi settings.
ip 192.168.0.4
subnet mask 255.255.255.0
router 192.168.0.1
The wifi symbol shows up in the top left of the ipod but again it just won't connect to the internet. IS my network too complicated or not how things should be setup? I know ad hoc works but perhaps i'm not doing it right.
Any help would be great. Thanks!

Can not create ad-hoc network

I am trying to create an ad-hoc network on my macbook pro 15.4" 1.5 gb of ram 1.83ghz first-gen and just upgraded to leopard
I am trying to create a network for internet sharing and I don't have it turned on internet sharing and then It says there is an error setting up a ad-hoc network and I have tried all the channels and nothing works help please thank you

I might have the answer. I had the same problem. Try changing the default name of the network to something short without an apostrophe. When I did that, I was able to create the network.
Note: my name is long and that is the name my computer has for me, so the default network name on mine was a mile long and full of punctuation.
Note: The first 20 or so times I tried to create the network, it wouldn't let me change the name, which I was going to change just for a laugh as opposed to doing it to not get the error message.
Maybe a coincidence and maybe not. Good Luck.

Cannot connect to ad hoc network with iOS 8

I am trying to use my iPad air on iOS 8 to connect to an ad hoc network I've set up on my PC (windows 7).
The network appears under devices, and when I try to connect it says "(Name) is not connected to the internet. Are you sure you want to use this network?" and gives the option to join anyways. I tried joining, but the internet does not work.
When I set it up previously and had my iPad on iOS 7, I did not have this problem. I am not sure how to fix it.
Unfortunately I do not have any other devices to test my network to be 100% certain that the issue lies with my iPad, but this is my belief since I didn't have this problem before upgrading my OS.

Same here!
Windows xp
I've been using adhoc with my iPhone 5 on iOS 7 with no issue, now with iOS 8 it drops the connection right after establishing.
The same behavior used to happen when I tried to watch any video on the iPhone iOS 7 through adhoc, it dropped the connection just like it does now on iOS 8.

Message reads Apple tv cannot sign in to Itunes until network time has been set; please try again later...help!

in setting up new apple tv, message says "apple tv cannot sign in to Itunes until network time has been set - please try again later.........is this an easy fix?

Welcome to the Apple Community.
Assuming this is not the first time you have used your Apple TV
You might try restarting the Apple TV by removing ALL the cables for 30 seconds.
Also try restarting the router.
If the problem persists, try a restore, you may want to try the previous procedures several times before doing this.
If restoring from the Apple TV doesn't help, try restoring from iTunes using a USB cable.
If this is a new Apple TV, in addition to trying the above, it may also be that your network router is not allowing access to the timeserver, check that your router allows access over port 123.

Data Transmission via Ad Hoc Network in LabVIEW

Hi,
I'm trying to transmit some data (position, velocity, and etc) from a laptop to a host computer.
Both the laptop and the desktop have wireless card installed so I thought it would be a good
idea to transmit the data via Wi-Fi using TCP.
However, the problem is that there is no router/modem in the area where the laptop is sitting
so I create an Ad hoc (computer-to-computer) network between the laptop and the desktop.
Then, I use "ipconfig /all" in Windows command prompt to extract the ip address as follows.
Laptop Wireless IP Address: 169.254.165.72
Desktop Wireless IP Address: 169.254.102.126
Desktop Ethernet IP Address: 129.94.229.230
I then use the example code in TCP library named "Data Server.vi" and "Data Client.vi."
I listen to port 6340 on both the wireless and ethernet card of the desktop on the server side.
And on the client side, I open a connection to port 6340 of the IP address 169.254.102.126.
However, the connection cannot be made. Does anyone know why this is the case?
Note: I have disabled all the firewalls.
Interesting enough, when 2 computers are connected to the same modem, their IP addresses
differ only by the last number (e.g. XXX.XXX.XXX.123 vs XXX.XXX.XXX.256) but when an Ad
hoc network is established, their IP addresses have 2 numbers which are different. (XXX.XXX.
102.126 vs XXX.XXX.165.72) I wonder if this has anything to do with the failure.
Thank you for any of your help.
Ron Liou
Solved!
Go to Solution.

I have somehow got this working.
What I did was
- again setting up Ad hoc network for the labtop and the desktop
- checking the ip address is still the same
              >> Laptop Wireless IP Address: 169.254.165.72
              >> Laptop Wireless Subnet Mask: 255.255.0.0
              >> Desktop Wireless IP Address: 169.254.102.126
              >> Desktop Wireless Subnet Mask: 255.255.0.0
- turning on the ICS of the ethernet card on the desktop
  (This resulted in different ip addresses beng assigned)
              >> Laptop Wireless IP Address: 192.168.137.21
              >> Laptop Wireless Subnet Mask: 255.255.255.0
              >> Desktop Wireless IP Address: 192.168.137.1
              >> Desktop Wireless Subnet Mask: 255.255.255.0
Now I use the desktop ip address (192.168.137.1) to open the connection
and it just works!!!??
I am quite happy with the fact that it is working but I would appreciate an
explanation on why an ICS is required.
Thanks!

I can't connect to ad-hoc networks with my iPod touch 4g AND IT ****** ME OFF!! (running firmware 6.1.2) Please fix this extremely annoying issue ASAP!!

I can't connect to ad-hoc networks with my iPod touch 4g AND IT ****** ME OFF!! (running firmware 6.1.2) Please fix this extremely annoying issue ASAP!!

Try:
- Powering off and then back on your router.
- Anything else here
iTunes for Windows: iTunes cannot contact the iPhone, iPad, or iPod software update server
- Change the DNS to either Google's or Open DNS servers
Public DNS — Google Developers
OpenDNS IP Addresses
- Try on another computer/network
- Wait if it is an Apple problem

Automatic creation of ad hoc network

I regularly have to facilitate workshops using Keynote slides. I use Keynote Remote to control the presentation which requires the creation of an ad hoc network that is password protected.
My procedure for this starts with the MBP where in the Finder menu bar I select the Airport Menu then Create Network… and fill in the text in the dialog box. Then turn on WiFi on the iPad and locate this network and join it using the password.
I tend to set the same name for my ad hoc network (showtime) and five digit WEP password which means that the iPad just locates and logs on automatically.
Now I want to automate the setup side as I want to reduce my set up time (and stress) when getting ready for a workshop (it's bad enough having to deal with strange data projectors and hard wired AV facilities) or when returning from a lunch break when I tend to take my MBP and iPad with me for security reasons.
I have found that Location services in the network pane of System Preferences completely lacking as it does not retain details of ad hoc networks users may create.
Anyone know of a good third party application that would automate this? Or a good Apple Script for Mac OSX 10.6.7 that would do it?

I'd forget about administering administrators, and framework-level activities here, and go down a level.
Here's a built-in low-level monitor for local networks:
/System/Library/PrivateFrameworks/Apple80211.framework/Resources/airport -s
You'll typically see the MAC addresses, names and channels involved. Polling that data could probably be scripted to broadcast a notification from a local (trusted) client, too. Roll that up with generic MAC data collection and you can probably identify the client device involved. (Until the gremlins discover MAC spoofing.)
The usual (technical) response to detecting and preventing these networks is not via client settings — phones can do ad-hoc these days, after all — but rather via tools that can explicitly detect rogue access points (APs) and such; an old intro and some Cisco Radio Monitoring details.
Some APs can send disassociate packets into rogue network, though that's a solution and an approach that I'd view rather skeptically, and would want clear and explicit administrative and legal buy-in before deploying anything like that. Same for collecting and saving MAC data and locality data; that can potentially be personally-identifying data. Remember also to account for the possibility of MAC spoofing when forming any administrative or disciplinary policies here, too.

Can connect to router but not ad hoc network. Works fine with iPhone.

My brand new ipad on ios 3.2.2 connects fine to my router and my jailbroken iphone running Mywi. However, I cant connect to an ad hoc network set up on my laptop running vista. My iphone connects to the ad hoc without any problems. I've tried everything, static ips, wep, wpa, hard resets, restoring, resetting network settings but no go. How can' everything else be fine but not connecting to the ad hoc network, especially since it works fine to connect with the iphone?
Btw, the ad hoc is for controlling music software on the laptop through wifi. It's not for getting internet.
Can anyone shed some light on this?
Many thanks,
L

Hi and welcome to the Apple Discussions.
Did you try doing a search, upper right corner of this window, on remote control? There have been a number of discussions during the last two weeks about remote control problems.
There have also been discussions about networking an iPad via another computer, such as iMac or MacBook Pro, using the computer's wireless card rather than a router.
See if one of those will answer your question.
