Re: CAX80 Multi-gig ethernet port dropping
What Firmware version is currently loaded?
What brand and model ethernet adapter do you have connected to the 2.5Gb port?
What CAT# cabling are you using? CAT6 is recommended...

Re: CAX80 Multi-gig ethernet port dropping
Interestingly, I went into the advanced wireless settings and turned wifi off completely. I have access points around the house, so that's not a connectivity killer for me. Turning both 5g and 2.4g radios KEEPS the multigig at full speed and there are no hiccups in data transfer. Everything seems to be working fine. I am going to leave it running for another full day and see of there are any interruptions, then turn wifi back on and see what happens. The ONLY change I made was to disable the wifi radios. Nothing else.

Re: CAX80 Multi-gig ethernet port dropping
OK, this is interesting. Disabling WiFi seems to help resolve the multi gig port behavior.
I recommend you contact NG support and let them know about this...
I don't see this issue on mine however mines in Modem mode.

I have firmware v2.1.3.5. I have tried testing the stability issue with 3 different devices, 1 2.5gb switch model trendnet teg-s350/a, 1 qnap 2.5gb switch qsw1105-5t and a 2017 iMac Pro with 10gb on board ethernet configurable to 10,5,2.5gb. Connecting the CAX80 to the switches caused a drop in communication and change over to 1gb only connection within 15-30 mins of each reboot of the modem. The auto negotiation option is not able to be set on either the netgear or switches. The iMac pro also dropped connectivity and switched down to 1gb in around the same time frame as the switches, but I was able to set auto negotiation to a static 2.5gb speed instead. This maintained the blue light on the multi gig port for the netgear, but within 15-30 minutes data transfers became wildly unreliable and jittery. I have tried a variety of cables, cat 5e, cat 6 and cat 7. I have tried 3ft cables, 6 ft cables, 10ft cables. The one that keeps the connection the longest is my cat7.

Re: CAX80 Multi-gig ethernet port dropping
Ok that's fine however the information asked for is also helpful for NG to review, relevant or not. Any and all information is helpful so that NG has what they need to review this and help get it fixed. Also removing the coax would not work to verify this as the CAX80 will auto reboot constantly until the coax line is connected and a signal is seen by the CAX80.

Re: CAX80 Multi-gig ethernet port dropping
This is a FACT. I went out my way to purchase a new USB 2.5GbE from ASUS and the problem still persist. I believe it is the NIC inside of the CAX80 itself. No matter what I do, no matter the settings, no matter the drivers Realtek... Even the latest that came out literally two days ago (March 22, 2022) the damn cable modem cuts out while gaming.
I can use my Wi-Fi 6 on my PC and it will not disconnect, but I want to be wired. I PAID for this to be WIRED and no matter the firmware on the device the NIC fails. I have spent enough money. I believe I need a newer revision of this product and hopefully a different NIC is inside of it. If not, Netgear will lose a customer for this generation of products. I'll come back in a few years when we're on Wi-Fi 8 or above.

Re: CAX80 Multi-gig ethernet port dropping
You'll need to contact NG support about this:
https://my.netgear.com/support/contact.aspx
If there is a problem, NG will need to review it and fix it as this is beyond forum help.
Good Luck.

Re: CAX80 Multi-gig ethernet port dropping
As mentioned in one of my posts already, I have passed this on to NG. Will take time for them to collect information and review and fix this. So for now. I recommend ANYONE using the 2.5Gb port, don't use it. The other LAN ports are available to use and don't seem effected by having WiFi radios enabled. NG has been made are of this issue some of you are seeing. So you'll have to patient while NG gets this fix. No idea when that will be. I'll try and post if NG passes any fix information to me regarding this.
Thank you.

Re: CAX80 Multi-gig ethernet port dropping
Honestly, this issue has been going on long enough. I have been reading these posts daily. I can see months of people complaining about the same thing. Over and over. I too have had a technician come out and say everything is fine. To be safe, I forced them to rewire the house. And guess what, the 2.5GbE signal continues to drop. I will do as you suggested and disable the Wi-Fi, for now. Luckily for me, I recently purchased this device on March 17, 2022, and I am a Best Buy Totaltech Member which allows me 60 days to use and return this product. As far as I see it, I will give NG up until May 15, 2022 to resolve this issue.
On the other hand, I have been looking for alternatives. I can purchase a Cable modem that supports a 2.5GbE and purchase a Wi-Fi 6 router separately. This solution will cost more, but I can at least isolate any issue with networking. Alternatively, I found that Motorola has a similar device to the CAX80-100NAS. The cable modem from Motorola is the MG8725. It supports DOCSIS 3.1 and touts the same AX6000 Wi-Fi 6. After dealing with NG and the CAX80, I performed deeper research into the product, and it seems safer for me to just swap it out.
Customers should NOT have to become unpaid technicians just to get a product they've paid for to function as advertised. I know I don't enjoy being lied to and/or robbed by companies I have grown to trust over many years.
Ready to digress? Here are some links to the competitor's product: Motorola - MG8725 AX6000 Cable Modem.

Re: CAX80 Multi-gig ethernet port dropping
Well, I really wish I had read this specific thread before I bought this unit and wasted all the same times the others have posted here with NG support.
I too have had this problem with the 2.5 Gbps port and now see the futility of trying a different unit, since it seems to be a product defect (firmware problem---call it what you will). So, it will have to be Motorola MG8725 for me also.
As to the person that was waiting until May 15th, please don't wait. As you can see, NG is still clueless about this one. As long as only fools with 1 Gbps ports buy this for the wireless part, they will ignore the minority that want the wired connection at this higher rate.

Re: CAX80 Multi-gig ethernet port dropping
I applaud your bravery to speaking up and against this product and lack-there-of support for people who spend their hard-earned monies on a company we've trusted.
I have been using the Motorola MG8725 every since returning that piece of tom-foolery and have been a very SATISFIED customer. It has the SAME Wi-Fi speeds with more customization and while the Wi-Fi is enable the 2.5GbE port WORKS. I am going on 36 days without an issue.
You will not be disappointed.

Re: CAX80 Multi-gig ethernet port dropping
...and on a side note, my WiFi bands both have passwords that contain a % symbol. I type the password in the configuration page and even click the eyeball button to confirm it. The passwords do contain the % symbol.
After I save the page, the passwords on the main page and on the advanced page both only show the text up to the % symbol. The symbol and any text AFTER it are not displayed. Since my devices are connecting, I am assuming the correct password was stored, but this is also another defect that the NG support team ignored when I told them about it.
