Hi,
In July last year, I purchased a HP Pavilion a6010n Desktop PC with Windows Vista Home Premium. I am connected to my brother's computer through Linsky's wireless PCI adapter and I have never had any trouble with connection to the internet until about 3 weeks ago. One day I turned on my pc and the computer icon in the task bar had a red "X" through it and when I clicked on "Connect to a Network", it didn't list my brother's computer or recognize I had any networks at all. When I opened Device Manager there was a yellow exclamation mark in front of Lynsky's Wireless-G Network Adapter.
After I called Linsky's and talked to a technician, they had me upgrade my firmware and changed channels in my settings. That worked . . . for a day. The next day the same thing happened - no networks. I called them back and was told it was a HP problem and to call HP. I called HP and they charged me 50 dollars and told me it was a Linksy's issue and to call them back. Over the last 3 weeks this has happened about 5 times when I start my computer. Each time a Linksy's technician was able to correct it, after doing a million things and being on the phone forever - but, only temporarily, and only to have it happen again. The last time I called I was told it was all because my Windows firewall was on and to turn it off, which I did. That seemed to work until today -- same thing when I turned on the computer.
What could be causing this? Any ideas? I read somewhere that Vista x64 may not be compatible with Linksy's products. Could this be why? Please, any help is appreciated.
