I have to keep rebooting to connect to internet

Your wireless network card in your computer is failing, or the cable to the computer is bad. Because you said wireless internet, I am going to assume that you are connected to the internet via wireless nic. If your pc hasn't been rebooted for a while you may want to try a reboot and see if that doesn't fix the issue.
However, if the problem remains you will likely need to get another wireless network card.

Plug your computer/laptop directly into router. Can you get to the Internet then?
If you CANNOT get to the internet when your computer is plugged into the router, reboot your router. If it doesn't have a power switch, unplug it. Leave it unplugged. Next, you need to figure out if you have another modem for DSL or Cable. If you do have another DSL or Cable modem, unplug that device to. After 5 minutes has elapsed for both devices being unpowered, plug in the DSL or Cable modem to the power source. Keep the router unplugged from power. After your DSL or Cable modem has powered up for 5 minutes, plug your router into the power source. Wait a few minutes. Reboot your computer/laptop. Try the wireless connection again.
If you CAN get to the internet when your computer is plugged into the router. Reboot your computer. Try to connect again. If you cannot connect after rebooting, make sure you are connecting to YOUR OWN wireless access point and not someone else's.
Do you have other computers/laptops/wifi devices that CAN/CANNOT connect to your wireless / access the Internet?

Keep a eye on Internet light. If it turns RED, then its a problem with internet connection..
As a qucik fix, Try to reboot the router when you face the problem...

check your internet connection. that's the reason why it's going off. if not. reinstall your yahoo messenger application:)

I called Radio Shack- for free!

check the power adapter voltage rating if it is the recommended one and reboot the D-LINK modern device and try it again.

sounds like the internet connection is not setup to Ur modem. When u unplug it redetects the modem and connects. try uninstalling the modem from the control panel - system - device manager. keep the modem connected and reboot. U may have to use control panel - add/remove programs any programs the modem cd installed. on reboot use the modem cd only to get the driver and let windows control the modem.
