My modem/router sends on both 2.4 and 5 ghz. I have put the wireless stick in the hp and configured it. You don't beileve it, the connectoin is faster and stronger as never before. Where can i find a document on how to open the laptop? I want to check if the adaptor inside is connected ok. ( i have a degree in electronics ) , and 2 years ago i replaced the cable three on my old HP laptop between the screen and the motherboard. It took 2 hours to open it ( i found the service manual ), but it still works.
