Most wireless networks are setup as infrastructure networks, meaning all communication is to/from a wireless access point/router that serves the same function as a switch/hub in a wired network as a central point to transfer communications from machine to machine. One works over the air the other through a wire.

There is an alternate form of wireless networking refered to as ad hoc -- in this version of wireless networking every wireless adapter can "talk" to any other wireless adapter configured with the same SSID (name) and security encryption (none, WEP, WPA). This is how somewhat less impromptu wireless networks are created similar to impromptu infrared networks some of us have used. One limitation of the ad hoc networks I have seen configured to date is access to the internet. I have posted an article where a stationary PC (required to be running for any other wireless machine to access the internet) with a wireless card in ad hoc mode could act as the router for wireless network but it required a cabled connection the internet. I suppose it could be a second wireless connection on a separate channel with a second wireless adapter in an infrastructure network but why? These types of networks are only recommended in another article for a limited (small) number of machines.

Based on this are you asking to create an ad hoc network to connect 2 PC's wirelessly without a wireless router or access to the internet from the wireless network (without a dedicated machine)?

I have an hp compaq and it connects everywhere except my house?


To connectyour computer to a wireless router, you click the Refresh networklist, then Choose your wireless network and then click Connectto your secured Wireless Network, it will asks for a Network Keybefore allowing you to connect into your wireless network. This NetworkKey is either the WEP, or WPA or WPA2 Encryption key that is used toconfigure the Wireless Router. The Passphrase is an alternate way tosetup the Encryption key.
When you are requested for a Network Key, you can just enter the Passphrasethat was used to configure the Encryption key in the wireless router.http://www.fixya.com/support/r5270415-network_password_network_addressFor information on securing your wireless network,configuring the wireless router and configuring the wireless card in thelaptop/computer, please click on this link and follow my instructions :-http://www.fixya.com/support/r3559128-wireless_router_security

My compaq presario 700 notebook cannot connect to internet thru neither cable nor wireless. It happened overnight. How I can check and solve this issue? Please help~~~


First of all, make sure your internet service is working. Then check your Network Connections in the Control Panel. Next could be your modem or wireless card is bad. Since I don't know if your main computer has internet, etc., I can't say anymore than that. If you take it into Best Buy, they might be able to replace the wireless care with a good one, to check the card. Good luck.

My wireless button does not work on compaq nx7010


Press the Windows key on the Keyboard and then press the "R" key while holding down the Windows key to open the Run dialog box.
Then, type "msinfo32" in the Run dialog box and click OK to open the System Information window.
In the left pane, click on the plus sign next to the Components then click on the plus sign next to the Network.
Under the Network, click on the Adaptor to view the information regarding all the network adaptors functional in the Computer.

You can view the Network adaptor's information on the right pane. On the right pane, check whether the wireless adaptor is listed or not.

Furthermore, you can check in the Device manager under the "Network Adaptor" category whether the wireless adaptor is listed.

If the wireless adaptor is not listed in either of the windows then the issue is hardware related and service will be required.

Wireless network is not connecting


There is not a lot of information to work with here. First of all, the computer is a desktop. Do you have a PCI or USB wireless card installed? You need a wireless network adapter in order to access your wireless.

Next, do you have a wireless router? If not, you need one to provide something for the wireless clients to connect to. If you do, you need to take note of the SSID, or wireless network name. This is the name that the Compaq desktop will be connecting to (with it's wireless network adapter.

In regards to the router, did you setup WEP or WPA wireless encryption? If so, Windows will ask for the key or passphrase to connect to your network and must be typed in identically to how it was setup in your router.

Something else to consider, if you do use WPA for encryption, some older wireless cards do NOT support it and if you insist on using encryption, use WEP.

Hope this helps!
