You will need to check the wireless settings of the router.
If your network is secured then make sure that you are typing the correct network key.
also make sure that the DHCP server is enabled on the router.
is there any computer connected to the router ?
If yes then you can open the router set up page on that computer.
Router set up page is the page where you can check all the wireless settings of the router.

Slow connection low signal


If a wireless network has low signal strength, the transfer of information across the network could be slow or you might not be able to access certain parts of the network. Here are solutions to some common problems with low wireless signal strength: Your computer is too far from the wireless router or access point. Move your computer closer to the router or access point. If your computer is portable, try moving it around to determine the range of the wireless signal and the best place to use the computer. If you can't get closer to the router or access point, consider buying and installing an external antenna for your wireless network adapter. Many wireless network adapters are set up so that you can attach an external antenna to them, which provides better reception than the built-in antenna. Check the information that came with your wireless network adapter to see if you can install an additional antenna. The wireless router or access point is turned off or isn't working properly. There are two things to try: o Make sure the router or access point is turned on and that the wireless signal light is illuminated. o Reset the router or access point by turning it off, waiting at least 10 seconds, and then turning it back on. If you don't own the access point or don't manage the network, contact the network administrator. There is interference from other devices. If you have 802.11b or 802.11g network hardware, it uses the 2.4 gigahertz (GHz) frequency. Other devices that use this frequency include microwave ovens and cordless phones. If you have 802.11a network hardware, it uses the 5 GHz frequency. Some cordless phones also use this frequency. These devices can cause interference between your computer and the network. There are two things you can try in this situation: o If any devices like these are near your computer, turn them off temporarily or move them farther away. o Change the router or access point settings to use a different wireless channel, or set the channel to be selected automatically if it's set to a fixed channel number. Sometimes one wireless channel is clearer than others. In the United States and Canada, you can use channels 1, 6, and 11. Check the information that came with your access point or router for instructions about setting the wireless signal channel. The network you're looking for is set to not broadcast its network name (SSID). Wireless routers and access points can be set up so that they don't broadcast the network name. In this case, you can't detect that the network is in range (in order to connect to it) unless you've previously connected to the network or you manually connect to the network using the service set identifier (SSID). To connect to a network that's not broadcasting, follow these steps: 1. Open Connect to a Network by clicking the network icon ( or ) in the notification area. 2. Click Unnamed Network, and then type the network information. The network will be added to your list of networks and will be available to connect to in the future when your computer is in range of the network.

Network adapter hp6505f


If your computer has a wireless network adapter, Windows will automatically detect wireless networks in range of your computer. You can see a list of wireless networks that Windows has detected in Connect to a Network.

  • Open Connect to a Network by clicking the network icon (eff2d36c-9e0d-4d1a-9859-3af14fa4ccfc_73.jpg or da12251d-1e9a-4032-afae-009876c6c5a3_80.jpg) in the notification area.

If Windows doesn't detect a network that you think is in range of your computer, it could be because of one of the following reasons:

  • The wireless switch on your computer is turned off.

    Many laptops have a wireless switch on the front or side of the computer. If your computer has a switch, make sure it's turned on. Some computers also use a function key combination to turn the switch on or off. Check the information that came with your computer for details on locating the wireless switch.

  • Your computer is too far from the wireless router or access point.

    Move your computer closer to the router or access point. If the computer is portable, try moving it around to determine the range of the wireless signal and the best place to use the computer.

    If you can't get closer to the router or access point, consider buying and installing an external antenna for your wireless network adapter. Many wireless network adapters are set up so that you can attach an external antenna to them, which provides better reception than a built-in antenna. Check the information that came with your wireless network adapter to see if you can install an additional antenna.

  • The wireless router or access point is turned off or isn't working properly.

    There are two things to try:

    • Make sure the router or access point is turned on and that the wireless signal light is illuminated.

    • Reset the router or access point by unplugging it, waiting at least 10 seconds, and then plugging it back in.

How to secure my internet connection via smc router


If you plan to have a wireless network, you should set it up so that only people you choose can access it. Here are a few options for wireless network security.

Wired Equivalent Privacy (WEP)
WEP is a widely used network security method. When you enable WEP, you set up a network security key. This key encrypts the information that one computer sends to another computer across your network. The receiving computer needs the key to decode the information so that it's difficult for someone on another computer to get onto your network and access files without your permission.

Wi-Fi Protected Access (WPA)
WPA was created to improve the security of WEP. Like WEP, WPA encrypts information, but it also checks to make sure that the network security key has not been modified. WPA also authenticates users to help ensure that only authorized people can access the network. If your networking hardware works with both WEP and WPA security, we recommend that you use WPA.

There are two types of WPA authentication: WPA and WPA2. WPA is designed to work with all wireless network adapters, but it might not work with older routers or access points. WPA2 is more secure than WPA, but it will not work with some older network adapters. WPA is designed to be used with an 802.1X authentication server, which distributes different keys to each user. This is referred to as WPA-Enterprise or WPA2-Enterprise. It can also be used in a pre-shared key (PSK) mode, where every user is given the same passphrase. This is referred to as WPA-Personal or WPA2-Personal.

802.1X authentication
802.1X authentication can help enhance security for 802.11 wireless networks and wired Ethernet networks. 802.1X uses an authentication server to validate users and provide network access. On wireless networks, 802.1X can work with Wired Equivalent Privacy (WEP) or Wi-Fi Protected Access (WPA) keys. This type of authentication is typically used when connecting to a workplace network.

IF THIS ALL DOSEN'T WORK TRY THE FOLLOWING:

Wireless network security recommendations
If you have a wireless network, there are some additional security precautions that you should take.

Use a network security key
If you have a wireless network, you should set up a network security key, which turns on encryption. With encryption, people can't connect to your network without the security key. Also, any information that is sent across your network is encrypted so that only computers that have the key to decrypt the information can read it. This can help avert attempts to access your network and files without your permission. Common wireless network encryption methods are Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA) and WPA-2.

Change the default administrator name and password on your router or access point
If you have a router or access point, you probably used a default name and password to set up the equipment. Most manufacturers use the same default name and password for all of their equipment, which someone could use to access your router or access point without you knowing it. To avoid that risk, change the default administrator user name and password for your router. Check the information that came with your device for instructions about how to change the name and password.

Change the default SSID
Routers and access points use a wireless network name called a service set identifier (SSID). Most manufacturers use the same SSID for all of their routers and access points. We recommend that you change the default SSID to keep your wireless network from overlapping with other wireless networks that might be using the default SSID. It makes it easier for you to identify which wireless network is yours, if there is more than one nearby, because the SSID is typically shown in the list of available networks. Check the information that came with your device for instructions about how to change the default SSID.

Position your router or access point carefully
Wireless signals can transmit a few hundred feet, so the signal from your network could be broadcast outside of your home. You can help limit the area that your wireless signal reaches by positioning your router or access point close to the center of your home rather than near an outside wall or window.

I have a laptop run Vesta trying to set wireless connection to HP Potosmart C4385 print using ad hoc network setup. When selecting Ad Hoc connection in the printer setup it saids it can not find it or...


For this specific issue about installing the printer to a wireless connection. You need to install the software first as a usb connection. After the successful installation of the usb connection then you can add a device and it should work.

Step one: Gather the necessary hardware and information Follow the procedure below before obtaining your wireless network:
  1. Obtain your network SSID and WEP. To simplify this process, press the Wireless button on the all-in-one, and select Restore Network Defaults . This turns wireless off and sets the all-in-one's SSID to hpsetup .
  2. Press the Wireless button to turn wireless back on. Look for hpsetup when you select your network.
  3. Make sure that wireless is enabled on the all-in-one.
  4. Make sure that the computer that will be using the all-in-one has access to the router/access point.
You will need the following to set up the product on a wireless network:
  • A wireless 802.11 network that includes a wireless access point.
  • A desktop computer or laptop with wireless networking support or a network interface card (NIC).
  • Broadband Internet access is required for some features of the HP software to function. Cable Internet or DSL are examples of Broadband Internet access. NOTE: If you connect the unit on a wireless network that has Internet access, HP recommends that you use a wireless router (access point or base station) that uses Dynamic Host Configuration Protocol (DHCP).
  • The network name, or Service Set Identifier (SSID). NOTE: The SSID is obtained from the wireless router or access point using the embedded web server on the router. See the documentation provided with the access point for more information.
  • The Wired Equivalent Privacy (WEP) key or Wi-Fi Protected Access (WPA) passphrase, if needed. CAUTION: To prevent other users from accessing your wireless network, HP strongly recommends using a password or passphrase and a unique SSID to your access point. Your access point might have been shipped with a default SSID, which can be accessed by other users using the same default SSID. For more information on how to change the SSID, see the documentation that came with your access point. NOTE: The WEP key and WPA passphrase are obtained from the wireless router or access point using the embedded web server on the router. See the documentation provided with the access point for more information.Some access points provide more than one WEP key. Use the first WEP key (index 1) when setting up the wireless network.
  • If the network is set up with an Apple AirPort base station and you are using a password instead of WEP HEX or WEP ASCII to access this network, you need to get the equivalent WEP key. See the documentation that came with the Apple AirPort base station for more information.
  • If IP address filtering is set up, verify that the unit address is listed.
  • If MAC address filtering is set up, verify that the unit address is listed. NOTE: HP cannot set up or change the SSID, WEP key or WPA passphrase. This information is required before connecting the HP All-in-One to the wireless network.
Step two: Connect to an integrated wireless WLAN 802.11 network Follow the procedure to connect the unit to the wireless infrastructure network:
  1. Insert the software CD.
  2. Click Install .
  3. Click Next on the Please Allow All HP Install Wizard Processes screen.
  4. Select Easy Install on the Choose Easy Install or Advanced Install screen.
  5. Select Through the Network on the Connection Type screen. Figure 2: Connection Type screen c01160788.jpg
  6. When it doesn’t find your device, click Next . Figure 3: Using Network Setup c01164746.jpg
  7. Plug in your device via USB (it will tell you when to disconnect later). Figure 4: Making a connection to your all-in-one c01160790.jpg
  8. Select your network from the list, and click Next . Figure 5: Wireless Network Setup c01160791.jpg
  9. Enter your WEP key (if applicable). Figure 6: Specifying your network security settings c01160792.jpg
  10. Once it has completed connecting to the network, click Next . Figure 7: Network connecting completed c01160793.jpg
  11. Disconnect the USB cable from the computer and the All-in-One . Figure 8: Disconnecting the USB cable c01160794.jpg
  12. Click Finish to complete the software installation process. Figure 9: Software installation complete c01160795.jpg

Home wireless network


Most wireless1.gif networks are setup as infrastructure networks, meaning all communication is to/from a wireless access1.gif 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 networking1.gif refered to as ad hoc -- in this version of wireless networking every wireless adapter1.gif 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's1.gif wirelessly without a wireless router1.gif or access to the internet from the wireless network (without a dedicated machine)?
