Need to
quickly connect up to another laptop wirelessly so you can transfer
some data without a router or Internet connection? Without an Internet
connection, you can’t use syncing services like Dropbox to share data
between devices easily. If you have a networking device like a router,
hub or switch, you can get the computers to talk to each other, but it
requires quite a bit of additional work (file sharing, permissions,
firewall configurations, etc).
However, if you have a laptop or computer that has a wireless card and so does your buddy, you can use the cards to make a wireless connection between the two computers. Once they are connected wirelessly (also called a peer-to-peer ad-hoc wireless network), you can easily share data between the computers.
You can create an ad-hoc network in Windows or in OS X and in this article I’ll explain the steps for creating the network for each OS. It’s important to note that ad-hoc networks in general have certain limitations that make them only useful for certain situations. Firstly, the speed of an ad-hoc network is normally less than that of a normal infrastructure network. Ad-hoc network specs only require a max speed of 11Mbps, which is way slower than b/g/n/ac max speeds.
Secondly, you can’t monitor signal strength of ad-hoc networks, so you have to make sure the computers are fairly close to each other and don’t move around a lot. Lastly, ad-hoc networks don’t support all the security features of normal infrastructure networks, so they can be more easily hacked.
On the next dialog, click on the Setup a new connection or network link towards the bottom.
In the new connection dialog, scroll down till you see the Setup a wireless ad hoc (computer-to-computer) network option.
On the next screen, it will explain what a ad hoc wireless network is and will let you know that if you’re currently connected to a wireless network, you’ll probably get disconnected. Go ahead and click Next.
Now you have to give the network a name, choose a security type and give it a security key. For the security key, you can choose from only three options: no authentication, WEP or WPA2-Personal. The default is WPA2-Personal, which is the strongest. Click next and then you’ll get a screen showing you that the network has been setup. Note that if you don’t check the Save this network box, once you disconnect from the ad hoc network, it will simply disappear. If you want to use it again, you’ll have to start from scratch.
Congrats, you’ve completed the first part! Go ahead and open your list of wireless networks and you should see your newly created one listed along with the rest of the wireless networks. Click on it to connect.
Once you are connected, you’ll see a message next to the network name that says Waiting for users. You network is now ready to accept new connections. Now it’s time to actually share data between the two computers. Let’s get into the details as it’s not as straightforward of a process as it seems.
At this point, you have several ways to share data between the computers. Let’s break it down based on the different scenarios.
– If the computers are all running Windows 7 and higher, you can use the homegroup feature that is built right into Windows. It lets you share music, videos, documents, pictures and printers easily.
– If all computers are running Windows, but there are also Windows XP or Windows Vista clients, then you have to join all the computers to the same workgroup and make sure that the network discovery and file and printer sharing are enabled.
– If the computers are a mix of operating systems like Windows and Mac, then you need to rely on just file sharing and permissions. The most important things here are making sure the user account in Windows has a password (otherwise you can’t connect to a file share) and enabling file sharing on the non-Windows operating systems correctly.
If there is already a computer that is joined to a homegroup on the ad hoc network, it will show up and you can join that or click on the Create a homegroup button.
We’ll create a new homegroup and on the next screen, you’ll be asked what items you want to share. You can choose from Pictures, Music, Videos, Documents and Printers. Click Next and you’ll get a screen with a homegroup password.
At this point, you just need everyone else to do the same thing as shown above, but to join the existing homegroup rather than creating a new one. Once you do that, you can open Explorer and click on Homegroup in the left-hand menu. When others join the homegroup, the shared data folders will appear there and you whatever is dropped into those folders will be visible to everyone in the homegroup.
Firstly. you need to make sure the ad hoc network is setup so that its network type is either Home or Work. To do that, open Network and Sharing center again and then click on the link that is below the name of the wireless network. If it already says Home, then you’re set. If not, then you want to click on it and set the network location to Home. That will allow sharing on the network with other computers.
The next thing to do is to make sure that all the computers are in the same workgroup. This is especially important for Windows XP and Windows Vista computers that you want to access via a Windows 7 or higher machine. By default, most Windows machines are in the WORKGROUP workgroup, so you may not have to change anything, but it’s a good idea to check.
On Windows XP, click on Start, right-click on My Computer and choose Properties. Under System Properties, click on the Computer Name tab. Click Change if you need to change the workgroup name.
On Windows Vista and higher machines, click on Start, right-click on Computer and then click Properties. Under the Computer name, domain, and workgroup settings section, click the Change settings button if you need to change the name.
Now the last thing we need to do applies to Windows 7 and higher. Go to Explorer and click on Network in the left-hand menu.
When you do that, you might see a bar pop up that says Network discovery and file sharing are turned off. Network computers and devices are not visible. Click to change. Go ahead and click on that and choose Turn on network discovery and file sharing. Once you do this, you should see all the other computers that are on the ad hoc network as long as network discovery and file sharing and enabled on them too. Just follow the same procedure on each computer to turn it on. The process mentioned above is just for Windows 7 and higher. Here’s how to do it on the other operating systems:
Enable File Sharing Windows XP
Enable File Sharing and Network Discovery Windows Vista
For all the advanced sharing options, go to Network and Sharing Center from the Control Panel and click on Change advanced sharing settings link.
Here you will find all the options for sharing, some of which we mentioned above. Make sure you are looking at the settings for the Home or Work profile and not for the Public profile.
The top section is network discovery and file and printer sharing, which we already talked about. Public folder sharing is if you want to allow others to access only the public folders over the network. If you’re doing this over a ad hoc network, then just turn it on.
Media streaming will allow others to stream content from your computer, but you can disable this and still share data between computers just fine. File sharing connections are set to use 128-bit encryption by default, so you should probably leave that setting alone. Password protected sharing makes it so that you have to use a user name and password from the computer you are trying to access in order to see the shared folders/files. If you don’t want to have to do that, then you can turn off this option. Lastly, homegroup connections will be accepted by default and those don’t require passwords to connect.
If you’re trying to connect from a Windows machine to another OS like OS X, then you’ll have to enable file sharing on those operating systems separately. On Mac, for example, you would go to System Preferences and then click on Sharing or File Sharing. Go ahead and add the folders you want to share and appropriate user permissions.
In order to access files on a Mac from a Windows machine, you have to click on Options and then check the Share files and folders using SMB (Windows) box.
I can’t go into too much detail in this post for different operating systems, but hopefully this will get you far enough and you can probably Google the rest. If you have any questions about connecting two computers wirelessly, post them in the comments. Enjoy!

Setting Up an ad hoc Network
This tutorial will be written for Windows 7, but you can follow the same instructions for Windows 8 and Windows Vista. To get started, open the Control Panel and click on Network and Sharing Center.
On the next dialog, click on the Setup a new connection or network link towards the bottom.
In the new connection dialog, scroll down till you see the Setup a wireless ad hoc (computer-to-computer) network option.

Share Data Across ad hoc Network
Now that you got the ad hoc network setup, go ahead and have the other clients connect to the network. Note that the wireless icon may continue to show that blue spinning circle icon even though the computer is connected to the ad hoc network. That is because it’s also trying to connect to the Internet, which it obviously won’t be able to do since it’s just a peer network.At this point, you have several ways to share data between the computers. Let’s break it down based on the different scenarios.
– If the computers are all running Windows 7 and higher, you can use the homegroup feature that is built right into Windows. It lets you share music, videos, documents, pictures and printers easily.

The most important things here are making sure the user account in Windows has a password (otherwise you can’t connect to a file share) and enabling file sharing on the non-Windows operating systems correctly.
Setting Up a Homegroup
The easiest way to share data between Windows 7 and higher computers is to use a HomeGroup. You don’t have to worry about sharing folders or files manually, configuring the firewall or adding passwords to user accounts. Everything just works and that’s nice! To get started, go to the Control Panel and click on HomeGroup.
If there is already a computer that is joined to a homegroup on the ad hoc network, it will show up and you can join that or click on the Create a homegroup button.
We’ll create a new homegroup and on the next screen, you’ll be asked what items you want to share. You can choose from Pictures, Music, Videos, Documents and Printers. Click Next and you’ll get a screen with a homegroup password.
At this point, you just need everyone else to do the same thing as shown above, but to join the existing homegroup rather than creating a new one. Once you do that, you can open Explorer and click on Homegroup in the left-hand menu. When others join the homegroup, the shared data folders will appear there and you whatever is dropped into those folders will be visible to everyone in the homegroup.
Workgroup Sharing
If you have computers running Windows XP and Vista in the mix, then the homegroup option will not work. In that case, you still have options. Firstly, if you are trying to connect from the XP or Vista machine to a Windows 7 or higher machine, then there are a couple of things you need to setup on the Windows 7 or higher machine.Firstly. you need to make sure the ad hoc network is setup so that its network type is either Home or Work. To do that, open Network and Sharing center again and then click on the link that is below the name of the wireless network. If it already says Home, then you’re set. If not, then you want to click on it and set the network location to Home. That will allow sharing on the network with other computers.

This is especially important for Windows XP and Windows Vista computers that you want to access via a Windows 7 or higher machine. By default, most Windows machines are in the WORKGROUP workgroup, so you may not have to change anything, but it’s a good idea to check.
On Windows XP, click on Start, right-click on My Computer and choose Properties. Under System Properties, click on the Computer Name tab. Click Change if you need to change the workgroup name.
On Windows Vista and higher machines, click on Start, right-click on Computer and then click Properties. Under the Computer name, domain, and workgroup settings section, click the Change settings button if you need to change the name.
Now the last thing we need to do applies to Windows 7 and higher. Go to Explorer and click on Network in the left-hand menu.
When you do that, you might see a bar pop up that says Network discovery and file sharing are turned off. Network computers and devices are not visible. Click to change. Go ahead and click on that and choose Turn on network discovery and file sharing. Once you do this, you should see all the other computers that are on the ad hoc network as long as network discovery and file sharing and enabled on them too. Just follow the same procedure on each computer to turn it on. The process mentioned above is just for Windows 7 and higher. Here’s how to do it on the other operating systems:

Password protected sharing makes it so that you have to use a user name and password from the computer you are trying to access in order to see the shared folders/files. If you don’t want to have to do that, then you can turn off this option. Lastly, homegroup connections will be accepted by default and those don’t require passwords to connect.
Sharing Between Operating Systems
Lastly, to share between a Windows and a Mac or some other operating system, you still need to follow all the instructions above for the Windows machines. If you’re trying to connect to the Windows machine, you should be fine doing everything mentioned above. The only issue is that you might have to create a password for your Windows user account in order to connect. You can try turning off password protected sharing as shown above, but sometimes other operating systems still require you to enter a password, so give that a try if you are not able to connect and can’t figure out why.If you’re trying to connect from a Windows machine to another OS like OS X, then you’ll have to enable file sharing on those operating systems separately. On Mac, for example, you would go to System Preferences and then click on Sharing or File Sharing. Go ahead and add the folders you want to share and appropriate user permissions.
In order to access files on a Mac from a Windows machine, you have to click on Options and then check the Share files and folders using SMB (Windows) box.
I can’t go into too much detail in this post for different operating systems, but hopefully this will get you far enough and you can probably Google the rest. If you have any questions about connecting two computers wirelessly, post them in the comments. Enjoy!
