CAX80 Internet cuts out everyday

90sScott · ‎2020-12-16

Hey Friends,

My internet access wired and wifi seems to go down everyday at the same time. Thought it was the DHCP lease renewing but that's on a 7 day timer, a simple reboot of the router fixes it but its really annoying to bring my network down once a day and I never had these issues with my old c70002.

Seems to cut out at 10am CST everyday tried changing the network clock and the cut out shifted as expected to 6am

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute them back ON.

90sScott · ‎2020-12-16

Have already had the isp run all checks and had a tech come out. Everything looks good on the ISP side they’re not seeing any service errors in their system.

FURRYe38 · ‎2020-12-16

What Firmware version is currently loaded?

Has a factory reset and setup from scratch been performed since last FW update?

90sScott · ‎2020-12-16

FW version 2.1.1.4 most up to date per net gear website. Came loaded with it. Have checked multiple times for an update since I installed this 7 days ago.

Have factory reset twice with a clean set up on a hardwired laptop. Still no fix.

NG support has had me change wireless channels, check ping, reboot, and reset multiple times. Maybe just a defective unit?

FURRYe38 · ‎2020-12-16

Any Wifi Neighbors near by? If so, how many?

What speed package do you pay for from your ISP?

I see your down channel are only locked in to 16. I presume you don't have 1Gb ISP services?

All this seen even before the recent FW update? If so, I presume you may have a bad unit that needs to be replaced.

I've had mine since last year and has worked well. Also had two EX7700s connectes for more wifi coverage. I've only recently took it off line to put my CM1200 online to work with it and my Orbi AX system. Otherwise my CAX80 has been great.

90sScott · ‎2020-12-16

Lots of wood neighbors nearby live down town in a 3 flat I can probably pick up 6 different networks from my house.

I pay for 1 gig from RCN Speedtests on the new Xbox confirm 1100 down. 60 up.

Just got the box for my birthday on the 9th. Haven’t had any issues other than the intermittency when it works it’s awesome.

You’ve had a cax80 since last year? Didnt it come out in July?

FURRYe38 · ‎2020-12-16

If your paying for 1Gb, then the channels are not all locking in. You should be seeing 31-32 channels locked on a 1Gb service.

Something you need to have the ISP service check for.

Sorry, I was thinking of a different NG product.

90sScott · ‎2020-12-17

Thanks I’ll get them back out here today but my speedtests are confirming 1 gig speeds.

Could RCN be running a different configuration than is common? They are a small localized carrier

FURRYe38 · ‎2020-12-17

Yes. They need to check the configuration file there sending down.

Most ISPs are using 31-32 channels.

90sScott · ‎2020-12-20

Checked config seems right on their end download speeds on 1200 mbps for me so I think it’s fine or a misrepresented issue.

NG Support sent me an RMA and a new one however it is in a boot loop and won’t factory reset at this point I’ll keep the old one as the connection has gotten steadily more stable.

FURRYe38 · ‎2020-12-20

Do you have the new RMA CAX80 connected to the coax line or do you have it disconnected from the coax line when you trying to set it up? For the CAX80, it needs to be connected to the ISP coax line or a auto reboot loop will be seen. Ya, I know, this is an odd behavior for a gateway modem. This is a known thing for the CAX80.

90sScott · ‎2021-04-28

Updating everyone here been through 3 CAX80's still no fix to this issue that I know of RCN says everything is good and netgear blames them.

At this point it's likely the code/device and I'm waiting for NG to contact me back
