I've kind of inherited the role of sysadmin at my company, even though I never went to school for something like that, and I really don't know what I am doing (haha). Long story short: yesterday around 40 of our clients connected to a webinar hosted off site, and shortly after the Internet went down at my work.

I connected directly into the modem (I know that's potentially dangerous) and still had no internet connection. It's a Cisco Comcast business modem, and we aren’t using it for routing purposes, we are using a separate router (a Cisco Meraki mx84). I restarted the modem, and after the painfully long start up period the internet was back up, both wired and wireless media worked.

I was wondering if there is something special about a TCP connection for a webinar host that could potentially cause problems when 40 hosts (40 source/destination depending on which way the traffic is traveling is my router) that my modem would have an issue with and sort of "crash"?

Any ideas would be great. Thanks in advance!

    Welcome to Network Engineering! The short answer is there's nothing inherent about TCP connections that would cause this. Unfortunately, you've given us very little to go on and speculation is off-topic here. It is more likely some action by Comcast, and you should check with them. – Ron Trunk Jun 12 at 18:14
