    Is your Wireless device Secured with a security password? A SSID?

    In the Tray Notification Area ,right click Network and Sharing Center, open Manage Network connections, Disable your Wireless Network connection , enable your Wireless Network connection. No luck, Open Control Panel, Device Manager, Open Network Adapters, right click on your Wireless Adapter, Uninstall and reboot machine. This will force Win Vista to reinstall the correct driver..

  • Louis Antwi Dec 16, 2012

    No luck I'm afraid. I don't think it is the Network adapter as the laptop can connect to some other wifi networks just fine. Yeah, you have to put a password in to connect to the network.

    Have you reset the Home Wireless Device to Factory Defaults? And start from the beginning .

  • Louis Antwi Dec 18, 2012

    How do I do that? Thanks for all the suggestions by the way.

    I don't know what the wireless device is , Make ,Model? FIRST, Connect a Ethernet cable from the laptop directly to the wireless device. Does it Connect? Can you Get on the Internet? YES or NO?

  • max carson

    Also Open Control Panel, Internet Options, click on Connections tab, click on Lan settings, If Automatically Detect settings is not CHECK , Check it. Reboot. Let me know , Yes or No.

  • Louis Antwi Dec 19, 2012

    Yup, I connect to the internet through the ethernet cable usually. It's a HP Pavillion dv6700 running Windows Vista. The LAN is set to Automatically Detect.

  • max carson

    Again, I don't know your OS or the computer make, model? Open Device Manager, Network Adapters, Uninstall the Wireless Network Adapter, reboot computer, the OS should ID the Wireless Adapter and apply the driver.

SOURCE: Laptop can't aquire IP address

I had the same problem, went to Microsoft and found this solution on line.
1. Click Start, click Run, type %SystemRoot%\system32\services.msc /s then click ok.
2. Double-click Wireless Zero Configuration.
3. In the Startup type list, click Automatic (if it shows Automatic already, change it, then put it back to Automatic, that will activate the Apply button) then click apply.
4. In the service status area, click Start, and then click OK.

That fixed it for me after fighting it for about a month.

SOURCE: I can't connect to the internet on my ACER Aspire

Most Acers use an IPN2220 Wireless card. If yours does and your router is using WPA or WPA2 (TKIP or AES) security then you'll need to update the driver by searching for it manually using the Custom button (Hardware) in Windows update (instead of Express). This driver is not part of XP service pack 2 or 3. In my experience if you don't update to the newest common form of home wireless security (WPA2 AES) then the older formats seem to become unreliable

Troubleshooting Laptop WiFi Connectivity Issues


Most laptop manufacturers provide an external switch to switch on/off the WiFi functionality. As a result, the first problem most new laptop owners encounter with trying to connect to a wireless network is that their WiFi has inadvertently been switched off. So, if you have a WiFi connectivity issue, the first thing to make sure of is that your laptop's WiFi external switch is on.

The next most common problem when it comes to WiFi connectivity issues is that the signal strength is too weak to hold a connection. This can be extremely confusing if the network is working fine for a person sitting at the next table. This could be due to several reasons. This person's laptop might have a more sensitive WiFi receiver, be set in just the right location where the signal strength is maximum, or even be accessing a different WiFi network other than the one you are trying to connect to. When you're troubleshooting a wireless connection, make sure to get as close to the router as you can, certainly in the same room if it's in your own home, so you can eliminate signal strength as a possible issue.

In order to prevent every stranger who walks by from accessing any network with WiFi capability, there are a number of security options that can be set on WiFi routers. The most common of these is simply enabling password protection, so that any laptop trying to connect to the network will have to provide a password for the initial connection (after that the operating system remembers the password). In order that you be able to connect to a WiFi network, you will have to set up your laptop's WiFi connection with the correct key. First, try the key printed on the router label, but if a custom password was created when the network was set up, you'll either have to find the piece of paper where it was written or chase the person who set up the network. If the password absolutely can't be recovered, search the Internet for how to reset the router (varies with brand), create a new password and enter it on all the computers that use the connection.

In some cases, it's easy to reset the password or turn the security on and off by connecting directly to the router with an Ethernet cable and typing the fixed IP address for the router into your browser.

Connecting directly by cable to the router is an important troubleshooting step for wireless connectivity even if you don't have a password problem. If you can't connect to the Internet even after plugging directly into the router, neither the wireless adapter in your laptop nor the wireless transceiver in the router are at fault.

If you plug directly into the router via the Ethernet cable and you gain access to the Internet, you can continue troubleshooting wireless issues. Check Device Manager to see if it's complaining about the network hardware. If not, and you still can't gain access at this point, the problem is either with the high speed modem and ISP, or a networking software issue within the operating system.

High speed modems, often called routers if they include a built-in router, are equipped with a series of status LEDs that can be used to diagnose many connectivity problems. Whether you have a cable modem connecting to the cable company, DSL via the phone company or one of the more esoteric high speed modems, they should always include an LED that tells you if the connection between the modem and the Internet has been established. If this link light is out, or has changed colors, say from the familiar green to an ominous red, power down the modem and turn it back on again. This hard reset will usually fix dropped connection problems caused by storms, power surges or signal interruptions, providing the modem hasn't been damaged. A modem/router will also include a status LED to show whether an Ethernet cable connection to your laptop is good, and your laptop will have a little status/activity LED for the network connection as well. While color coding isn't universal, solid green usually indicates a good connection, and blinking green or orange usually indicates activity. Some modems include an LED to tell you if the DSL or cable link to the ISP is good even when the Internet isn't functioning.

Operating system issues affecting connectivity can include firewall (security software) settings that prevent your computer from establishing communications with the Internet Service Provider (ISP), or the failure to install the software that ISP requires. Unfortunately, there are also more complicated problems that will require drawn out conversations with the ISP's technical support department to troubleshoot.

If you're adventurous, or desperate, you'll find all sorts of third party software online that will reset the Windows stack or change registry settings back to defaults, but you're better off trying the tech support route first if a software glitch is at the bottom of your problems.

Can't find the wifi signal


Assuming that you are using Windows, the D-Link is properly installed, and that you can go to Start; Settings; Network Connections: and your D-Link appears as a wireless network and that when you double click on it you see a box that lists "wireless networks" that indicates either " no wireless networks in range, or there are some networks, but they are all encrypted, then you are not in range of a wifi hotspot or free wifi access point. If you live in a mobile home as I do you will find that the metal walls effectively block the signals.A simple device that you can use to increase your signal strength can be found if you google "Surf rider" when you are on the net. Find a friend with a laptop, go to a Mcdonalds or a Starbucks hotspot and test your D-Link to verify that it is working Dan

I can't get internet connection even though it says my connection strength is "excellent."


The netbook is working fine. The WiFi connection or SPID may require you to login as in it is a protected signal. The "Excellent" means that you are receiving an excellent signal from the router. What you want is internet access which is upstream of that. Try a different SPID or connection.

Excellent signal low speed transfer


You can boost the signal range of a WiFi computer network in several ways: Answer:
  • reposition your router (or access point) to avoid obstructions and radio interference. Both reduce the range of WiFi network equipment. Common sources of interference in residences include brick or plaster walls, microwave ovens, and cordless phones. Additionally, consider changing the WiFi channel number on your equipment to avoid interference.

  • upgrade the antenna on your router (or access point). WiFi antennas on most wireless base stations can be removed and replaced with more powerful ones.

  • add another access point (or router). Large residences typically require no more than two APs, whereas businesses may employ dozens of APs. In a home, this option requires connecting your primary wireless router (access point) to the second one with Ethernet cable; home wireless routers and/or APs don't normally communicate with each other directly.

  • add a bi-directional WiFi signal amplifier to wireless devices as needed. A WiFi signal amplifier (sometimes called "signal booster") attaches to a router, access point or Wi-Fi client at the place where the antenna connects. Bi-directional antennas amplify the wireless signal in both transmit and receive directions. These should be used as WiFi transmissions are two-way radio communications.

  • add a WiFi repeater. A wireless repeater is a stand-alone unit positioned within range of a wireless router (access point). Repeaters (sometimes called "range expanders") serve as a two-way relay station for WiFi signals. Clients too far away from the original router / AP can instead associate with the WLAN through the repeater.
