This is a problem which suddenly appeared, after years of use with no problem. It is just this one device, Aspire laptop, that has the problem (we have 2 smartphones, 2 desktops, 2 laptops and a tablet). So nothing wrong with network, router etc. It's a problem for this one computer only.
1) laptop will initially connect to network, automatically as one would expect.
2) after several minutes of use it will state that there is no longer an internet connection (at that moment other devices connected no problem and router signals all look good).
3) closing browser and re-opening does no good.
4) doing a restart of the computer ALWAYS fixes the problem, it comes back up with WiFi connection, but it will lose the signal again, same way in another several minutes.
Should I purchase and replace the WiFi card myself? I have replaced boards in computers several times over the years and understand the precautions.
