Help! I have XFinity internet, and their technical support team insists the problem lies with my modem/router. I’ve had an Arris G36 Gateway for less than two years, but for the last few weeks, my internet keeps disconnecting, and when it does work, it’s painfully slow. The XFinity rep said there could be missing or outdated boot files. Could that be correct? If so, how do I update them? Thank you in advance, sincerely.
