I use an Acer Aspire. I have a wireless PCI card in it. I have a Belkins G router and it is plugged into my DSL modem. Some what often I have a connection to my router, but my internet won't hook up. Even more strange, my computer will be hooked up to the internet one moment, but then the next I can't get back online. My modem shows that I have the internet, but my computer won't hook up through the router? Any ideas?
