I have a Motorola SBG6580 router that was supplied by my Internet provider Brighthouse(time Warner) and I am beginning to suspect it may be the cause of my problems. For the past few months, I've been having issues downloading programs and such. Many times, most of the time, when I go to install a program or app, it ends with an CRC Error in the file. It began to show itself with issues updating Norton Anti-virus but shows up when trying to download and install other items. I just figured it to be an issues with pretty much every item that is linked to the internet through this router. My PC, my Other PC(Both plugged into the router). Every computer that is linked via the WiFi also seems to have issues including my son's WiiU. It continues to fail in updating.
Is there a way foe me to run a diagnostic on this router to test and see if it truly may be the cause of the download issues?
