I'm having the same problem on my desktop and have also figured out it is the network adaptor (I have the same Qualcomm listed above). The internet connection drops randomly and I have to disconnect and reconnect to the network. This is despite the computer recognizing that the wireless connection is fine. The driver is updated to the latest version. I searched online and have tried various fixes to no avail (I turned off the option to let the computer disconnect the connection to save power, which was on despite me having a desktop. I also tried unchecking IPv6 and changing the roaming policy to very low, neither of which worked.) This is very frustrating, especially on a computer less than 6 months old. I need an actual working fix to this or for Acer to replace the network adaptor if it is faulty.
