Over the past few days, my computer has been experiencing drop-out of the local wifi connection that I set up in my apartment. I know it is my computer and not the network/router because my roommate's computer always works fine, even when I have lost internet connection.
The interesting thing is that the globe still appears in the bottom right corner, as if I am still connected. But if I try to use an internet function, it either goes really, really slowly, or it does not work at all.
I have fixed the problem a couple times by restarting the connection on my computer, which then takes a few mins before the internet works again, even after the globe appears. A couple times this has not worked and I had to restart my computer, and the problem has increased in frequency (just happened 2 times in 15 mins). I was using a Java application that connects to the Internet at the time. Interestingly, 2 times when I 'diagnosed'the internet connection, it said network security settings were not right, but I just clicked accept on the current settings (never changed the password) and it started working again.
I do not know what is causing this problem. I will promptly provide you with any information/specifics of my computer, network, and error messages as requested (I don't know what information is relevant right now).
Any help would be much appreciated!
