Hi all,
I'm dealing with a very annoying network issue. My client is randomly dropping internet throughout the day. Sometimes only once, sometimes 2-3 times a day. If we let it sit, it doesn't seem to come back on its own. When we reset the modem, it rarely comes back online. When we reset the router, it always comes back online. This tells me it's most likely router related.
Here's a little info that may help:
Router: Cisco RV320.
ISP: Charter, static IP
Server 2012 R2 Essentials is acting as DHCP and DNS, Cisco router is set to DHCP relay to the server.
Everything has been running perfect for a year. The ONLY thing that changed is they hired a new employee. This new employee is using his own Macbook. Shortly after he started, they were experiencing wireless issues. As a way around it, he decided to get internet access to his laptop via his cell phone. Following that, massive network issues arose. I traced that down to the setting his Mac was using to pull internet from his phone - it was acting as a DHCP server, so the company's server decided to shut down DHCP services. Turning off that setting resolved that issue, and all seemed fine. The next day, the internet began dropping again. The local LAN works perfectly, just the internet is dropping out.
I've called Charter, they swear it isn't them.
I've upgraded the firmware on the router.
I've double/triple checked the DNS configuration on the server - can't spot anything.
Reading countless Cisco forums I discovered a threat discussing a setting that could be causing the router to try to "load balance" to the second WAN even with nothing connected, so I tried changing those settings.
My next step is to factory reset the router and reconfigure it. It's a very simple network, it won't take more that 5 minutes.
Following that, since it's a dual WAN router I was thinking of configuring the other port. My thinking is maybe there's something messed up with that port.
It just seems WAY to coincidental that all this just magically starts acting up as soon as this new employee started working with them. It's not impossible, anything is possible with electronics... This environment is all brand new, I completely started from scratch just about a year ago. I have about 15 of these Cisco routers in the field, including 2 of my own, and I've never seen any of these issues. Can anyone think of anything this Mac might be doing to crash the network? Or maybe something else I can do besides waste money on a new router when it may not be the problem?
