..is purchase a separate USB wireless adapter that attaches to a USB port on the notebook. Disable the onboard wireless adapter completely in Device Manager, then use the new one as the primary wireless access adapter.
Those Pavilions frequently had issues with failing wireless adapters.. After tinkering with a few of them, we simply purchase the USB models and we're up and running a a few minutes.
Hope this helps.
I have an HP Pavillion dv9000z notebook, Windows Vista, NVIDIA graphics card. I replaced my old Linksys router because after 4 years I was no longer able to connect to a network wirelessly. My new router is Linksys WRT54G2. The new router works great wirelessly for about 4 days and then I have "no network" to connect to. I have uninstalled all programs associated with the router, restored the router back to factory condition and installed the router again. Works fine for a few days and then the same problem...no network. My husbands Dell computer works just fine wirelessly and is always able to connect to the network I have set up. If I hard wire directly to my Wild Blue modem, I connect to the network. So it does not seem to be the router or my ISP. Something on my HP prevents me from locating my network. I understand that HP had a recall on some models due to graphics card going bad. Mine did not appear to be one but that doesn't mean that my graphics card might not be going bad (have no other symptoms of this happening). Could my graphics card be causing this problem possibly due to overheating? Or is it something else like a firewall, or an Antivirus program (running Avast on both computers so i don't think it's that). How do I correct this problem?
