unstable helix wifi connection

My laptop keeps losing its connection to our home network, forcing me to restart the computer each time to regain access to the internet. This issue only happens on this network and this is the most recent device in our household, which should have the most up to date tech. Once acquired, the connection may last from a few minutes to a few hours with no apparent pattern. Other devices on the network do not seem to have this issue, and since the helix tech doesn't see a reason for it he decided it has to be a problem with my device and won't help. What could be causing this?
