I am having an issue with my internet connection. We have wireless connection in my home and we have comcast as our provider. My family can get online when I can't. I get bounced off and on from the internet all day. On occasion this happens when I am also on my aircard. Not sure if there is a conflict somewhere or what. I use firefox and really like it. I downloaded and used Avast. I also have a new modem from comcast and linkys and I re did all the settings. Any suggestions??
