If the problem is with one device you can try "forgetting the network". On Windows 7 you would go into Control Panel > Network and Sharing > Manage network connections and remove your network from the list. Try connecting to your network and re-enter your PSK.

SOURCE: Laptop can't connect to DSL-G604T

You need to configure your router and use WPA encryption so that all accessing device can connect to it.


The obvious reason why the dell laptop can't connect is because of the WPA encryption set. It is different compared with what your router is actually broadcasting: WPA2.

So you can choose one of the 2 things to alter. Change your router's WPA2 encryption to WPA or change your Dell's setup to WPA2.

SOURCE: I have a just installed

This seems to be a common issue for that particular router with the Nook Color reader. Most people end up fixing the problem be either turning off n support, changing the security to WEP instead of WPA/WPA2 PSK or changing the firmware on the router to DD-WRT which is a Linux based alternative OpenSource firmware suitable for a vast majority of WLAN routers on the market

SOURCE: My Acer Aspire 5336 can't connect to a wireless with a WPA2-PSK security standard. What can I do?

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_address

http://compnetworking.about.com/cs/wireless/f/infrawireless.htm

Question: What is infrastructure mode in wireless networking? Answer: Infrastructure mode wireless networking bridges (joins) a wireless network to a wired Ethernet network. Infrastructure mode wireless also supports central connection points for WLAN clients. A wireless access point (AP) is required for infrastructure mode wireless networking. To join the WLAN, the AP and all wireless clients must be configured to use the same SSID. The AP is then cabled to the wired network to allow wireless clients access to, for example, Internet connections or printers. Additional APs can be added to the WLAN to increase the reach of the infrastructure and support any number of wireless clients. Compared to the alternative, ad-hoc wireless networks, infrastructure mode networks offer the advantage of scalability, centralized security management and improved reach. The disadvantage of infrastructure wireless networks is simply the additional cost to purchase AP hardware. Note that home wireless routers all feature a built-in AP to support infrastructure mode.

Tip

How to restart Wireless Zero


Like any other service, sometimes the Windows Wireless Zero service needs to be restarted. It could be because of a glitch or error, or it could be because a third-party utility (such as the Dell WLAN application) stopped it. In any event, restarting Wireless Zero and getting Windows to automatically see and manage your wireless connections is a breeze. (If you have a third-party program managing your wireless connections, you'll either need to stop that program or uninstall it before restarting Wireless Zero.)

A. On the Start menu, right click on My Computer (in Vista, it's just called Computer) and select Manage.

B. When the Computer Management console opens, click the plus sign next to Services and Applications to expand that section.

C. Click on Services.

D. Scroll down the list of services until you find Wireless Zero Configuration, and click on it. (It may help to maximize the window.)

E. Toward the top of the window, under Wireless Zero Configuration, you'll see either Start or Restart underlined; whichever one it is, click on it.

F. Close the Computer Management console.

G. Right click on the Windows wireless icon in your system notification tray and choose View Available Wireless Networks.

H. Click Change advanced settings on the left side.

I. Go to the Wireless Networks tab and put a check in the box marked Use Windows to configure my wireless network settings.

J. Click OK.

The list of available wireless networks should automatically refresh itself, and you should be able to connect to any network you could connect to before (as long as you have the proper keys and credentials).

Wireless card in E1505 Dell not finding networks in range


The 1390 WLAN Minicard may not be configured to communicate with your wireless router.
Check the wireless router settings, (check the wireless settings on your other computer) and configure the 1390 WLAN with the same settings eg. SSID, WEP/WAP encryption, etc.
Is MAC address filtering enabled on your wireless router, if so add the MAC address of the 1390 WLAN to the MAC address list in the wireless router.

Check the TCP/IP properties of the 1390 WLAN card the Internet protocol should not have a fixed IP address, set it to Obtain an IP address automatically including the DNS.

Use the Ipconfig command to see the IP configuration of the network cards.

Use the Ping command to see if you can communicate with wireless router.

1a) Check whether HW switch is ON and the wireless system service is running.
1b) Switch on the WLAN Access Point (router) SSID broadcasting.
1c) Scan WLAN networks by the notebook. Can you see your home WLAN? If not, there is HW or SW problem in your wireless adapter probably. If WLAN is visible, continue by next steps.

2) Remove all WLAN security on both sides (AP and notebook): Authentication = none/open, encrytption = none.
3) Activate DHCP server in the router and set the dynamic IP assigning on WLAN notebook interface.
4) Select your home WLAN SSID in the list and try to connect.
5) Wait and check status. Is WLAN connected? Does obtain the notebook an IP address?
6) In success case set the WLAN security.
