Cax80 keeps dropping internet connection
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 mi...
Hi,
My Gateway: Nighthawk CAX80, FW V1.1.0.41 - just bought less than 7 days ago.
I am having the same, if not a similar, issue where I get the "connected, no internet" message. I primarily see this on mobile device. But end rebooting the CAX80. This is only impacting the wifi connection as I am hard wired to my work laptop with no issues. I am using a RG6 coax cable. I do not have any splitters, etc.
At the time where I re-attempted to connect to the wifi with the mobile phone I see this in the log;
(I replaced numbers with #)
| [DHCP IP: 192.###.#.##] to MAC address dc:bf:e9:a4:eb:2c | 1 | Tue Sep 22 08:08:22 2020 | 192.168.1.43:0 | 0.0.0.0:0 |
When the CAX80 works as expected it performs well, but I need to try and resolve this before my return window closes. I have reset to defaults twice in the last few days.
Thanks
YES! THIS!!! Netgear obviously did some update and messed up DHCP. My wired static IP address devices work just fine when the rest don’t. Whatever this is it’s been going on for weeks and they need to FIX IT. NOW!!! And stop updating and adding crap people don’t need. People are working from home now and are reliant on a stable Internet connection which a $500 device should be able to provide. Oddly enough Netgear doesn’t even recognize its own device in its model list on this forum.
- Awesome. Not only does this forum take millennia to load but it doesn’t do inline replies. I was replying to lurksalot post which I will repost below.

Have they checked and confirmed signal levels on the line up to the modem?
Ensure they have provisioned the modem from there side.

- This is my exact problem except my hardwire & wireless disconnect. Has your problem been resolved yet? If so, what did you do?
BEB7474 Here are all the tips I've tried:
Are you having problems with the modem dropping internet connections or with the DHCP services? If your having problems with DHCP services, please make a new post and we'll try to help you out.
If your having problems with the modem and internet services the modems connected too, please give more details regarding this.
FW used on the modem. Etc.
