IPhone - computer-to-computer network

I am trying to set up my office computer so that I can access the internet on my iPhone using the internet connection of my computer. I have gone through all the set-up procedures and I have made the connection, but I still cannot access the internet.
In the preference pane of my computer is states that the Wi-Fi is connected but has a self-selected IP address and it may not be able to connect to the internet. ... That is true.
I tried configuring the Wi-Fi connection on my computer with the same IP address etc as my computer, but that just knocked off my LAN connection.
What do I need to do on my iPhone or computer to get the internet connection?
Any help would be very much appreciated.

Are you using a wifi router at home? Does your computer have the ability to transmit wifi?
If you are using a wifi router at home, and it is transmitting, you need to go the wifi on the iPhone and turn it on and see if it is "seeing" the network. If so, you can follow the prompt to join.
If you are using the home computer that is set up to transmit wifi for usage, then after you have finished configuring the computer, you should be able to broadcast the network, turn on wifi on the iPhone and join as mentioned earlier.
All of it depends on how you are getting wifi. If you are transmitting from a router, or another computer.

IPhone has constant problems with Computer-To-Computer network

I use a Computer-To-Computer network to connect my iPhone with my MacBook Pro when I'm at the office. This enables syncing of Things and OmniFocus between my iPhone versions of these programs and the versions on my MacBook Pro. I have one of the original (2G) iPhones. I daily go to my Airport icon on my Mac's menu bar, click on Create Network, and set up a password. I'm using 40-bit WEP.
This sort of syncing procedure worked fairly well until iPhone OS 3.0. Ever since then, it's been completely unreliable. I've tried changing the channel a number of times, and of course rebooting both the iPhone and the computer dozens of times. It's still a problem.
Anyone heard of this networking problem with 3.0? Any info appreciated! Thanks.

yes, i have been having problems with computer to computer networking to iphone as well. for now, the only thing that keeps a steady connection is removing the sim card, so keep a paper clip handy.

Is it possible to save a Computer-to-Computer Network?

I might be overlooking something obvious, but I do not see a way to save a "computer-to-computer" network.
For instance, here is what happens:
I create a new "Airport" network on a macbook pro to sync with my iPhone. works great. But when I restart the macbook, the network does not appear in the list.
From here, I check the network settings. AirPort is "On", signal is strong, but no Network is selected. Furthermore, in the dropdown box, my network is not shown in the list.
So my only option is to start all over and re-create the network. Certainly there is a way to save the computer-to-computer network and keep it available after restarting my computer?

After you create it, click on Locations and choose edit Locations, then the + symbol and give the newly added location a name, then click Done.
Next time you login, you will be able to select that setup from the  menu item, Location.

Mountain Lion, Apple TV and computer to computer network

Hi there,
I have a second generation Apple TV with the 5.2 software update.
As per these instructions, I cannot seem to create a computer to computer network which the Apple TV will recognise.
The computer to computer network I create works because my iPhone can find and connect to it. But the Apple TV cannot even find it.
I cannot use the Internet Sharing feature because I do not have an Internet connection (or any other network connection) to share from any other input (ethernet, etc) on my Mac.
What are my options? Thanks!
Kiel

Not tried to set one up recently, but AppleTV 2 and 3 don't seem to play well with WEP which may be the issue here.

Setting up computer to computer network caused wifi to stop working

Hi,
I set up a tether using the FlashArmy App with my Iphone 4S and Macbook Pro. I created the computer to computer network and all worked well. However, now I can't return to my wireless network. It sees the network SSID but won't obtain the IP Address. Any thoughts? Also, when using the Assistant, it will bring up the SSID but when I enter the correct password, it indicates the password is incorrect.

Simply turning the router off, waiting 5 minutes, then turning it back on solved this mystery. I had to restart the Macbook Pro as well but all is back to normal.

Error creating computer-to-computer network

Hello all, is there a fix for this issue yet?
Creating computer-to-computer networks over Airport is broken in SL for many many users!
Ad-hoc networking over wifi is essential for many iphone applications, come on Apple, sort this out?

Ok, thanks ... So Apple doesn't actually read these boards?
I've perused the numerous pages of numerous threads about the problem, and seen the numerous unhelpful replies.
Sorry, but i'm not cool with this. Apple has progressively crippled my computer's functionality with firmware/software updates. First it was the superdrive, (firmware borked by update, had to be replaced) now ad-hoc networking. These are known issues which have affected thousands of people, and have been discussed in these boards extensively. Discussions are often marked as "Solved" and locked down, when it is clear that the only solution is replacement of affected hardware as it is simply not supported by Apple anymore. This is a tactic to force people to buy new Macs. Several Mac users I know do not tinker, they just want ti to work, so they tend to buy a new Mac every 2-3 years because the "old" one has slowed down (usually due to a full hard drive) - or - in some cases, they accepted an Apple update.
The iPhone is a premium smartphone and its wifi connectivity with the Mac is much advertised. Guess what, it doesn't work for many who upgraded to Snow Leopard- yeah, "Error creating computer-to-computer network"
There is no solution other than replacing the laptop's Airport card (an operation too daunting for most users) or messing around wih windows Atheros firmware flashers . For most people it really means go back to Leopard, and if you don't know how to do that and your machine is out of warranty, tough.
I'm sorry if this isn't the place for complaining, i have already contacted Apple about it but the site says told not to expect a response. Maybe if enough people have the sme issues and make enough noise something can be done.
This must be a very easy thing to fix in the OS but the fix is probably blocked by some policy to accelerate the obsolescence of Macs. Sooner rather than later, your Mac wil be "legacy".

How to connect my macbook pro to a computer-to-computer network?

how to connect my macbook pro to a computer-to-computer network? My home computer is a Window 8 OS. Thx.

The easiest way, and it may work from scratch, is to share the folders/drives you want access to on your pc, noticing what are the default parameters (eg "workgroup" etc.).
Then, you can connect your mac directly by ethernet, for instance, and, in Finder, go to > Network, you should see the folders/drives. You may be asked to provide user/password.
Don't get confused by regular/crossed ethernet cable, as mac can cross by software, so a regular cable will be ok.
Anyway, either you isd modem has the ability to connect several devices (multiple ethernet sockets, or wifi), or you can buy a router, which isn't expansive.

Computer - computer network and internet sharing

I apologise if this has been discussed elsewhere - please point me to any useful links.
I have a G4 iMac and iBook (running 10.4.6) both with airport extreme cards installed. I would like to use a computer to computer connection for file / printer sharign and most importantly to share the ethernet connection to the internet running through my iMac.
I would be extremely grateful if someone could point out how to do this and incorporate a practicable level of security (I don't want any of the hundreds of people in adjacent flats downloading lord knows what through my connection).
Having accomplished this, I then need to be able to create a similar connection when required so that when required I can share the internet connection from the iMac with our PC laptop running Windows XP service pack 2.
So, the simpler the better, instructions for creating a computer - computer network for internet and file sharing between two Macs and following that between the Mac with the internet connection and a Windows laptop.
Thank you very much in advance.
G4 iMac USB 2.0 / G4 iBook Mac OS X (10.4.6)

You don't need to setup up computer to computer connection if your using internet sharing. Once you start internet sharing then your 2 computers are connected togther.
I would be extremely grateful if someone could point out how to do this and incorporate a practicable level of security (I don't want any of the hundreds of people in adjacent flats downloading lord knows what through my connection).
The problem you have is that if you enable internet sharing on one of your macs to share its connection over airport then the only level of security you can enable is WEP encryption.
The problem with WEP encryption is that it offers no real security and can easily be cracked. WPA is the only security you should consider using and unfortunately OSX does not have WPA encryption functionality when using the built in internet sharing function.
Your best solution is to get a wireless router that has a SPI firewall an WPA encryption. Depending on what your current internet connection is and how it is provided would determine the best kind of router to get.

How do I use a computer to computer network?

I tried to set up a computer to computer network form my mac to connect with my pc notebook.
my notebook says it is connected but I do not see my mac anywere, what do I have to do to acess my shared folder on my notebook?

Perhaps the actual computer-to-computer wireless network is not really working.
Start by making sure you have created the computer to computer network properly on your Mac by reading Communicating with other computers wirelessly. Do NOT implement a password, since this feature is difficult to get working properly with a PC at the other end of the connection.
Then configure your PC's wireless adapter to connect to the wireless network you created on the Mac.
Note that having a wireless networking connection between these two computers sounds like a nice high-tech idea, but a direct cabled connection would be (a) less trouble to set up, (b) would be far more secure, and (c) would provide a dramatically faster connection.

IChat audio/video not working: bonjour over computer-to-computer network

My girlfriend has a brand new MacBook Pro 15". I have a 3 year old PowerBook. Both running 10.4.9 and iChat 3.1.8. We are currently sitting right next to each other, and yet have been unable to connect to an audio or video chat by any method.
To completely eliminate the router from the equation I created a computer to computer network which she joined. Both of us have our firewalls off, and both of us have our Quicktime streaming speed set to 1.5Mbps. We tried to create an audio connection over Bonjour. I got an error -7 and she got an error -8.
There are many threads reporting the same error, but most of the solutions involve changing router settings. I figured that since this is on a computer-to-computer connection there is no router involved. It would be nice to be able to get this working over the general internet, but I figure if it doesn't work in this very limited setting it will never work. Any help? Much appreciated.

Yep - did that on both computers, to no avail:
Here's the first section of the error messages from both computers. (I can post more if it's helpful.)

On wake up, my iMac tries to set up a computer-to-computer network

I have a 2006 Intel-based iMac. I use it on a wireless network in my home.
When it wakes from sleep, it looks for a computer-to-computer network that has the same name as my wireless network. Needless to say, it doesn't find it and I have to manually get back on my wireless network.
I have cleared and reset all of the network settings, but to no avail. I suspect it has some rogue setting that it keeps returning to.
Do you know how I can get rid of this problem? I am tempted to trash the Network folder in my preferences, but am unsure if that would cause me other problems.
Thanks for any help in advance.
Geof

the problem seems to be from the user logout being less time than the energy save time.
Go into system preferences to fix the issue.
good luck!!!!!

"Device" with my SSID showing up in WiFi Menu as computer to computer network

OK guys this is weird...
A few weeks ago a noticed my SSID showing up unprotected under "device" in my wifi menu across all my ios devices. It shows up as protected in the list of all the networks in my neighborhood, but not under "device". Out of curiosity, I connected to it, and realized it was a computer to computer network. The problem is that I didn't create this network. It just showed up. I do not have internet sharing turned on. The only time it goes away is when I connect to my wireless network. When I switch back to Ethernet, it shows up again. I thought it would be as simple as deleting the network, but it doesn't show up anywhere else. I've tried formatting my hard drive. Still there. I've tried unplugging my router. Still there. I've tried everything I can think of to get rid of this thing, and it just wont go away. This has me slightly concerned. Any help would be appreciated.

William,
Thanks for your reply. I'm not sure which device it is, if any. It just displays my SSID. One secure, one not. I did not create this network, and I do not have hotspot turned on to my knowledge. I do have all my devices logged in to iCloud so I can message and call on my devices, but I wouldn't think that would automatically create an ad-hoc. I never saw it before last week. I attached a screenshot. Thanks for your help.

Computer-to-Computer Networks

I'm on a business trip right now (my first with my new MacBook Pro) and when I clicked on the Airport Extreme icon at top, I noticed much more than just the hotel's wireless connection. There are also a couple "Computer-to-Computer" networks listed. Out of curiosity, I clicked on them individually -- it allowed me to connect to one, superimposing a little computer icon over the Airport Extreme icon at top.
My question is, what did I do when I connected this network? I looked in Finder to see whether something else showed up and there was nothing. I also disconnected the Ethernet cable to see if I could use the Internet through this network and it didn't work. So I'm confused as to what this means. And if it means someone's computer is broadcasting a signal, does it mean that my MacBook Pro is broadcasting a signal too? And would I be able to tell whether someone has connected to my computer?
Sorry if this is all very basic, but I'm still very much a newbie.
Thanks.

Some people who use Internet Connection Sharing at home don't turn it off when they travel, and so that it is then broadcast and you can pick it up.
Most of these computer-to-computer networks are benign, however not all are.
I would recommend to everyone to never connect to them.
I was coming home on the train in November last year when my Sony VAIO said it had found some wireless networks. I usually keep the wireless off to conserve battery.
I checked the wireless networks list.
I was surprised to see these networks as I was on a train and just coming out of Paddington.
Now the first two may have been unprotected home networks that you get when you use a wireless access point out of the box and not configure it.
However the second two look more interesting.
There is no such wireless network as vodafone WLAN hotspot and FREE was a bit suspicious. However the reason they look really suspicious is that these are not wireless access points but computer-to-computer networks which you can tell because of the icons.
This immediately threw up warning bells for me, so I turned my wireless off.
What did concern me was that an innocent passerby could think these were wireless access points (or more scary the computer could join them automatically). There are trains in the UK with wifi access and some train operators use wireless networks for their onboard ticket machines.
These are not true evil twin wireless networks as has often been reported about, but certainly was the first time I had seen something like this.

Strange computer on my Computer-to-Computer Network

I'm on my computer and I just noticed a strange computer ("LeeMiser's Computer") listed under the Computer-to-Computer Network heading on my connectivity icon for my Airport. I'm using 128 Wep Protection with a password (and just changed it) and checked "create a closed network" option on the Airport Admin Utility (which is supposed to hide my name from neighbors) but this computer is still showing up under Computer-to-Computer Network. Is this person tapping into my wifi. Why can't I get rid of him?

A Computer-to-Computer network or Ad-Hoc network is created by the AIrPort Extreme card built-in your Mac. It does not rely on a separate wireless router ... so the AirPort Utility settings are independent of this type of network.
Instead, a Computer-to-Computer network is controlled via the AirPort icon in the OS X menu bar. The only security setting available is WEP. WEP, as you are most likely already aware, is no longer considered a secure standard ... and can easily be "broken."
It is possible that someone has figured out your password. The question that remains is do you really need to have a Computer-to-Computer network or is your real goal to connect your Mac to a wireless router?

10.4.7: Problems with computer to computer network

Since updating both my computers (G4 Powerbook and G5 desktop)to OS 10.4.7 the computer to computer network doesn´t work anymore. When accessing network connections the computers just don´t show up which they have done before the update.
No problems with the Internet connection though, everything works well.
I have seen some threads where network problems have been described but I didn´t find a workaround. Is there any solution to the computer to computer network problem?
Thanks very much for your help
Regards
Raindog

Hi all,
I have the exact same problem.
When my PowerMac used to have 10.4.6 it was no problem to connect via Finder's Command-K from my MacBook Pro running 10.4.7.
But now, after I updated my PowerMac to 10.4.7 this doesn't work anymore.
As Wolfgang said, Internet works fine from every computer in my local network. The Mac mini (Intel) runs 10.4.7, too, and I can connect from the MacBook Pro to the Mac mini (and vice versa) without any problem.
But connecting from & to the PowerMac (Dual G5 2.7) with 10.4.7 doesn' work.
I did the update via the online Software Update procedure. It sometimes seems to be better to not use this but download the full installer and use this for the update.
I'll try that soon and tell you how it comes out.
Cheers,
Stefan.

HT1711 Why my playlists do not match between my iPhone & computer?

Why my playlists do not match between my iPhone & computer?

What do you mean they do not match? Are the songs wrong, are the names of the playlists wrong, are they not all synced? Do you have iTunes set to sync all songs and playlists?
