Compaq presario F500. Wireless internet connection not working. Internet works when plugged into modem. D-Link wireless modem working perfectly. Constant red/orange light on next to wireless switch at front of laptop.

Is your cable modem also a wireless router?

From my search on it, it is not a wireless router.

This means you need to attach a hub or a wireless router to your cable modem so that more than one computer can connect to the internet simultaneously.

Go out and buy a wireless router. Connect the wireless router to your cable modem.

Connect your desktop to the wireless router with an ethernet cable.

Then you should have internet on your desktop.

Let me know if this helps. Give me a good rating and vote for me please.

check to see if your wireless card is detecting, and check your drivers, they may need updating.

Uninstall the device from the device manager and in the device manager do this operation "Scan for hardware changes" , then u can find the wireless network adapter with no drivers installed. Then install the wireless device drivers , Ur Problem will be solved.

try updating the drivers..

Do you know for sure there is a wireless connection in the area you trying to connect, Wireless internet isn't accessible every were and when it is available it could be protected by a security pass phrase. The only way to really get full use out of your wireless internet is to go to a company that sells the wireless internet cards

Anyone having a wlan/wireless problem with a compaq F730us, please report it to HP corporate headquarters and HP/Compaq. The problem is with the mainboard, its a manufacturer problem. Only HP/Compaq can fix this for free, but we have to let them know that the F700 series is also having the same hardware issues as the f500 and other series. Here is a link to hp website so you can see that hp is aware of the problem, we just need to get the f700's added to the list.

Compaq/HP laptops that have a builtin wireless adapter have a wireless transmitter symbol near the bottom edge of the LCD screen.
If you don't have a wireless adapter you need either a PCMCIA or a USB wireless adapter. My choice would be a PCMCIA type because it frees up a USB port for other devices.

Try to remove the preferred networks on your Presario then try connecting again. If you have wireless security enabled on your router, you have to enter that. Make sure that the settings on your router is the same as your wireless adapter so that they can synchronize.

If you have difficulty with that, just ask me and I'll answer as soon as I can.
