How do you know your notebook is connected to your wifi AP? Did you try pinging the gateway? If not, open your command window & type "ping 192.168.0.1" (put in your own gateway address.) If you get replies, then ping something outside of your network: "ping 4.2.2.2" (this is a verizon dns server). If you get replies, then "ping yahoo.com". If it does not fail at any of the above steps, you don't have a connectivity problem. If you fail any of the above, then report back & we'll continue the troubleshooting.

The list of wireless routers that are available in Windows is very limited and the signal strength of any router that is detected is weak. This can occur when the Lite-On USB Wireless 802.11 b/g hardware and Windows are not able to fully synchronize the signal strength data. Figure 1: Example of detected wireless devices when the antenna cable wire is connected to secondary port Figure 2: Example of detected wireless devices in the same environment when the antenna cable wire is connected to primary port To correct this error , download and install Lite-On USB Wireless LAN Driver Update (sp35177) (in English) from the HP Web site. This update should only be applied if your PC has the Lit-On USB Wireless LAN adapter and is exhibiting the symptom. As a work-around, you can connect the wire that runs from the wireless antenna port to the primary port on the cord as follows: CAUTION: This product contains components that can be damaged by electrostatic discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap connected to a grounded surface.

1. Open the side panel.
2. Find the wireless networking board by following the antenna wire connected to the wireless networking antenna port on the back of the computer. Figure 3: Wireless networking hardware 1 - Wireless network board 2 - Antenna wire 3 - Wireless networking antenna port
3. Very carefully, disconnect the small wire from the board by gently pulling the end of the wire away from the board.
4. Connect the wire to the other available port on the board. Figure 4: Available port
5. Replace the side panel, connect the power cord, turn on the computer, and use the computer again to verify that wireless signal strengths have improved.

Atheros AR5007EG adapter only WEP compatible. Wireless networks using WPA(2), or anything else won't work. If network is unsecured, it should connect.

Please make sure that the wireless antenna switch is on. Then enable the wireless feature using the hot key combination for your laptop (if available but need not be done since you were able to detect networks earlier). If you are using Vista, please click on Start-Connect to to see if your laptop is now able to detect networks.
If laptop is not able to detect any networks, please uninstall the wireless network adapter by going to Start - Control Panel - Classic View - Device Manager - Network Adapters - select the one for the  Wireless Network Adapter - properties - driver tab - uninstall - ok. Then please restart your laptop. Click on Start - Connect to  and see if your laptop is now able to detect networks.
If laptop is still not able to detect wireless networks, please click on Start - All Programs - Accessories - System Tools - System Restore then choose a restore point (date) which is a possible time when your laptop was able to detect wireless networks. Laptop will restart automatically and notify you if the restoration is completed. Try Start - Connect to. Hope it works this time. Thank you.
