Hello I have a HP Pavilion dv5003 cl Notebook PC Wndows XP. My problem is I cannot connect wirelesss. This laptop model has a wireless button to turn on and off, for some reason it doesn't work anymore. When I start>control panel>network connections the only thing I see is the local area connection using the ethernet cable, the wireless network connection is not even an option anymore. Ive also notice that while trying to Reinstall wireless device drivers( thinking that may be the problem, has suggested by hp customer care) by start>my computer>properties>harware>device manager> network adapters where there should be the option "wireless lan" there's none. Only an option that says:realtek rtl8139 family pci fast ethernet nic . Please, any suggestions?
