Hello, just need a question answered. I purchased a Nighthawk CAX80 in January 2022. How do I confirm it’s Docsis 3.1 ready? I don’t have the box or a manual from my original purchase. My cable provider just advised they’ve upgraded and want to make sure I don’t have to spend more $$$. Thanks in advance.

At the top of this page, click on DOWNLOADS, feed in your model number CAX80 and it will take you to a page where you can download pdf versions of the data sheet and user manual. The data sheet indicates the CAX80 has a built in DOCSIS 3.1 cable modem.

Re: CAX80
Who's your isp?
When you log into the router and check its cable connections page, if the ofdma channel (s) lock in, its connecting at the docsis 3.1 spec. A lot of time you see them only enable docsis 3.1 on the downstream channels.

Re: CAX80 - not responding as expected
Hello, our ISP is Mediacom. Finally got it reconnected and have confirmed its compatible w/ Mediacom’s system; however, download speeds fluctuate from 12.41 to 407.52 nowhere near the 600 speed Mediacom is advising they’ve now switched us to. I’m not a tech guru…know how to hook things up and understand basics. I do believe there’s still something not right. Latency when watching YouTubeTV; dropped connectivity throughout the day. No one is gaming or downloading large files (except TV). Any thoughts?

Re: CAX80 - not responding as expected
Can you get logged into the Modems web page at 192.168.1.1?
If so, What FW version is loaded?
Please post a copy and paste of the modems connection status and event log page.

Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
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.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

Re: CAX80 - not responding as expected
Tried logging into Modem webpage. The only thing it will let me do is reset the password. I reset the PW correctly and it takes me right back to the PW reset screen. I have a service call with Mediacom on Wednesday. I'm out of time/patience today. THANK YOU SO MUCH for taking time out of your day to try and help! Greatly appreciated!!!

Be sure to clear out all browser caches. Close the browser then re-open the browser then try again.
Try a different browser.
Walk thru the reset PW recovery option as well and see if this will get the PW reset and you logged in.
