How do I setup a ad-hoc network (peer to peer)?

Bill Premium,VIP join:2001-12-09	How do I setup a ad-hoc network (peer to peer)? Since there really isn't anything saying exactly how to do this, I decided to summarize into a thread. If there is anything more to be added, feel free to reply. 1. You will need one wireless network card for each computer 2. Go into the network card properties and set the SSID to something unique. Make sure to set the SSID to the same value on each machine. If you don't, the network will not work properly. 3. Go into the network card properties and set a channel for the wireless network to use. Make sure you set the channel to the same number on each machine. If you don't have the same value set, the network will not work. 4. Set a static LAN IP on both computers. Be sure to put them on the same subnet and in the same IP range. Ex. If you set the IP on one machine to 192.168.1.1, be sure to set the other machine to something inside that same range (192.168.1.2-254). You may also want to take a look at »Linksys FAQ »How do I set a fixed/static IP address on a LAN PC?. 5. Set the network cards to run in "ad-hoc" mode, instead of infrastructure. If you don't want to share your internet connection, this should get you up-and-running. If you do want to share your internet connection, follow these steps: 1. Enable "ICS" on the network connection which has internet connectivity. Write down this computers IP address, since it will be the "host" computer. If you are not running Windows, or don't have the option to run ICS, consult Google,or this forum, for other connection sharing options. 2. Set the default gateway of the network card on the second computer to the host computers IP address. 3. Set the DNS servers for the network card on the second computer to values given to you by your ISP, or ones which you know work. Also, keep in mind, when sharing your internet connection over an ad-hoc network, the host computer must be on, and connected to the internet, if you want the second machine to be able to access the internet. To test connectivity: 1. Go to Start. 2. Go to Run. 3. Type "cmd". 4. Type "ping x.x.x.x", where x.x.x.x is the IP of one of the machines in the network. 5. If the ping is successful, your network is up and you should have full connectivity Regular filesharing setup and problems still apply to ad-hoc networking. Be sure to take a look at »Wireless Networking Forum FAQ »Why Can't I Share Files? if you run into filesharing problems. You can also find an additional guide here -- The new Secure-Wifi.net is open!

funchords Hello Premium,MVM join:2001-03-11 Yarmouth Port, MA kudos:5 1 edit	reply to Bill Re: How do I setup a ad-hoc network (peer to peer)? Bill, G R E A T J O B A couple of questions to answer or points to add if you wish. This may be more detail than you intended to provide... 1. Question: Is there a form of WPA security available in an Ad-Hoc network? Or are you limited to a maximum wireless security of WEP? 2. Point: In an ad-hoc network, every station in the network must be able to communicate with every other station in the network. If any part of the network has a hidden node, the network will perform very poorly. 3. Question: When running in ICS mode, can you use the DHCP server of the ICS machine to handle addresses? 4. Point: An 802.11g card need only support 11 Mbps in ad-hoc mode to comply with the standard. Many cards, however, support full-speed connections in Ad-Hoc mode. In Windows, these options are found on the Advanced settings in the card's Configuration Properties page. -- Robb Topolski http://www.funchords.com/ Hillsboro, Oregon USA The enemy of freedom is dependence.

Bill Premium,VIP join:2001-12-09	1. Yes, I believe you have the choice of WEP or WPA. 2. Yes, that's a good point. If there's a hidden node, I don't even see how it'd "perform very poorly". If there was already a "hidden" client connected, how would another machine connect? Or do you mean something else? 3. I'm not really sure. Does Windows XP even have a built-in DHCP server (since most people are using that OS these days)? I don't have an XP machine to check on, so maybe someone can answer that for me. If it doesn't, I'm sure there's probably a third-party program out there that can do it. I googled regarding the issue and came up with this "Microsoft Knowledge Base" article, which applies to Windows 2000 server, and, from what I've seen, some problems with other operating systems often roll over to others. 4.

But further, they would interfere with links that otherwise would work. It would be one of those troubleshooting nightmarkes -- Why are the speeds so bad between A & B? Turns out it's C causing interference. -- Robb Topolski http://www.funchords.com/ Hillsboro, Oregon USA They who would give up an essential liberty for temporary security, deserve neither liberty or security

AoErat join:2005-09-02 Tucson, AZ	reply to Bill Re: How do I setup a ad-hoc network (peer to peer) Where exactly do I need to go on Win XP SP 2 to set the SSID and the Channel for my wireless card? I couldn't find setting such as these in the Wireless Network settings under Network Connections, nor under the card's properties in Device Manager.

arunima join:2005-09-18 India	reply to Bill Re: How do I setup a ad-hoc network (peer to peer)? Hey! I just came across your forum while searching on adhoc network on google.I have really meager knowledge on this subject and you might find my question somewhat dumb! My wireless router stopped working due to some electrical trouble with it. So I am trying to set up an adhoc network so as to share internet on both my desktop and laptop. I have ethernet connection on my desktop connected through Realtek RTL8139 network card. I have a linksys wireless G PCI adaptor in the desktop and this doesn't have any slot to connect the ethernet cable to it. My laptop is wireless enabled. Is it possible to share the internet connection on both??

cristi71000 @wmin.ac.uk	reply to Bill Hi, I have 2 laptops, and I connected the wirelessly. I disabled all firewalls, antivirus, etc. The wireless connection succeeds with no problem, however the computers won't see each other at all. Ping fails. Any suggestions? Thanks, Cristian

funchords Hello Premium,MVM join:2001-03-11 Yarmouth Port, MA kudos:5	This is a sticky thread ... perhaps you should start your own topic in this forum. Attach an IPCONFIG /ALL for both computers (assuming Windows). You will get helped.

Alan_Briggs join:2005-03-06 England	reply to cristi71000 Despite following all the steps listed I have consistently failed to set up an ad hoc wireless network that works for more than an hour or so. I just bought a new pair of wireless adaptors and I still cannot get anywhere. As far as I can see the two adaptors are stuck in a continuous loop of completing the connection. If I let Windows take control it says 'acquiring network address' - whatever that means. Each card can see enough info from the other one to attempt to make a connection but they never succeed. I'm not sure if Windows (XP) gives reliable information about connectivity of peer-to-peer connections. I suspect that if you think you have a network but you cannot ping the other end even with the firewalls down then you are in the same state as I am!

funchords Hello Premium,MVM join:2001-03-11 Yarmouth Port, MA kudos:5	said by Alan_Briggs: If I let Windows take control it says 'acquiring network address' - whatever that means. This means that the network has sent a DHCP (automatic addressing) request and is waiting for a response. Because you are not using a wireless router, this DHCP request is going to fail. But you can set up a manual (static) address. In Windows Help, do a search for "static addressing" and you'll find a step-by-step guide. If you need suggestions for IPs, may I suggest Computer #1: ... IP Address: 192.168.7.101 ... Netmask: 255.255.255.0 (leave the other fields blank) Computer #2: 192.168.7.102 ... Netmask: 255.255.255.0 (leave the other fields blank) This will allow computer #1 and #2 to communicate with each other. -- Robb Topolski -= http://www.funchords.com/ =- Hillsboro, Oregon USA ...

Alan_Briggs join:2005-03-06 England	Re: How do I setup a ad-hoc network (peer to peer) Sorry, I was not being sufficiently clear. If I set static IP addresses then Windows SAYS it is connected but the utility software that comes with the wireless adaptors is still stuck in a loop trying to connect but failing. That's why I think that others in the same state as I (not even being able to ping the other end) sometimes think they have a connection when they don't.
