Hi. I am using an Asus wireless router and a Netgear wifi adapter for the computer. When I am using the internet, it keeps disconnecting randomly and when I check the wifi adapter sometimes my router's is in the available connections list and sometimes it isn't. It reconnects on its own after some time, sometimes as soon as a minute and sometimes as long as 20 minutes. At first I thought something is wrong with the wifi adapter so I switched on my laptop and noticed that the same was happening to the laptop as well. My desktop is about around 18-20 feet away from the router. I've tried changing the channel of the router to an isolated one but that doesn't help. It is very very infuriating. Any suggestions as to how I can fix that? I've connected the laptop with the ethernet wire and it works fine, so its not the connection.
