@gevkc Thank you for making us aware that you keep having to reboot your laptop due to you connectivity issues. I would be more than happy to help find a solution to this problem you're experiencing. So that we don't go over something you've already done, can you please share with me what troubleshooting steps have you completed on your own other than rebooting the laptop? Have you by any chance used the Xfinity app to reset the modem? How about a power cycle, have you tried that?

@gevkc 

Have you had a chance to see if any of those tips apply ?
