Router Randomly Dropping Internet Connection
I am coming to this forum with a month long problem. FIrst let me explain my environment: Residential Brick House 2 Floors 3k Square foot Spectrum Internet 200 up / 10 down Arris SURFboard SB...
Thanks for all of the replies and great info. I have not made any changes yet but turning on the logs, I wanted to see the logs before I started making too many changes. My internet is dropping multiple times a day now, like even multiple times an hour. When the internet drops, I am losing ethernet connection too instead of just wifi now that I have the orbi system.
When the internet drops, what should I look for in the logs? Here's what the logs looks like over the last couple hours when I have had internet drops...

who did this? You or NG?
That was a device restart. I just had the internet drop 10 minutes ago and I looked at the connection stats and I see that the router actually rebooted itself. The logs got replaced and the connection stats says that its only been up for 10 minutes. Now that I can see that the router is rebooting each time I lose the internet. Where do I start next?
I would check your devices for this MAC address> d8:c4:97:c2:9d:a4
I would start by turning OFF ALL Wired and wireless devices accept for 1 wired PC. Watch the behavior of the RBR to see if the RBR reboots any. I would power OFF the ISP modem and RBR for 30 seconds then back on. Watch the behavior with the 1 PC. If you don't notice anything. Start by adding a device. One at a time. Watch the behavior. See if anything changes after devices start connecting...

- Recently purchased Nighthawk CAX80. Never had problems w/ my internet connection before hooking up the Cax80. For last 2 wks since my Cax80 has been connected, im getting disconnected like every 20 min, ethernet & wifi. When I check out my Nighthawk app, it tells me I'm connected. Doesnt tell me I'm disconnected til I try to do a speed test. I've spent hours on the phone w/ NG "expert techs." Thats just been frustrating (language barrier & wait time) & a waste of time. I called Cox cable to make sure everything was good on their end. They said signal & connection are strong. When I lose connection, the lights continue to light like normal. I have only 2 devices connected. My cell & a streaming box. Any advice or help would be great. I read the posts above & I'm wondering if that worked?
