Is it possible to run the desktop via an Ethernet cable and to use a laptop with wireless using the same router? I have tried to connect the laptop using wireless to a working ethernet system but it does not recognise it. As soon as I connect the laptop using an extended ethernet cable however it does work. What is the method?
Check your wireless settings on your router (using your desktop). First, try setting a strong router password (not just the admin:password type to get in), then turn off all wireless security, and see if your laptop connects. It should be able to.
Then, add WPA security to the wireless, with a strong passphrase. You'll need to enter this on your laptop, and see if it works.
