Hey! I purchased a Time Capsule to go with my MBP and wanted advice about the setup. The Time Capsule arrived before the MBP and I was able to set it up using my iPad and have connected wirelessly to it. While considering the purchase, someone said I should call comcast/xfinity to disable the wireless feature on the modem provided by my cable company - it's an Arris Docsis 3 modem. I did not do this after setting up time capsule and the speed was fine. Do I need to do this? Please let me know the best approach? Thanks!
