CAX30 Slow Internet Speeds

JohnnieWalker22 · ‎2021-08-25

Hello all

Need some help please. I recently decided to get my own modem instead of renting one out from Xfinity. I got tired of their XB7. I bought a brand new Nighthawk CAX30 (AX6 AX2700) about 3 days ago from Costco. As soon as it was provisioned by Xfinity (Gig Speed Plan), I noticed the speeds were not there (Only about 200Mbps wired & about 150Mbps Wifi). I called Netgear and they blamed Xfinity (Down Bonded Channels were weak). Turns out it was a bit of their fault. Had Xifnity come out and they noticed that they were splitters on my line and going to other units on my condo building. They put a brand new coax line from my apt to the the box out in the alley. My speeds improved a tiny bit but they are not there yet. When the Tech tested the coax line in front of me, he was getting about 1200 Mbps. But when he hardwired to the CAX30, he was only getting about 250 Mbps. Technician gave up, blamed the router and left. Right now, wired to the gateway, I am getting about 280 - 385 Mbps and about 200 Mbps wi-fi. (Speed tests were done with several devices, Phone, Laptop, iPad, Nighthawk App and the Speed Test tool in the Router GUI) I

I made sure the router is up to date, restarted it several times. The only thing I have not done is Hard Reset it after the Tech left. I wanted to know if there was any other settings I am missing before I Hard Reset it? If I hard reset and is the same result, is there anything else I can try? I wanted to try as much as possible before I spend hours on the phone with Netgear..

Thank you all for you help.

You can try disabling qos, access control, parental controls, and traffic monitoring. then do a reboot and see if it hits full speeds.

If it doesn't, then try the reset.

You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:

Cable Modems & Routers

Modems are a bit specialist and, apart from @plemans , there may not be that many cable modem experts hanging around in this section.

In the meantime you could visit the support pages:

Support | NETGEAR

Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.

You may have done this already. I can't tell from your message.

I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.

Yes, I made sure all that was turned off.

UPDATE: I finally did the restore to factory settings. Now I am getting around 550 Mbps. Not the full speed yet, but definitely happier with the speeds.

Do you have a screen snip of the cable connections page and the event logs?

photos have to be approved by a moderator and it can take a while. Or you can click on "choose file" and attach them individually

I have experienced the same issue with this router since buying it at Costco in July 2021. My firmware is up-to-date with version 1.4.10.8.

After initial setup, I get 350 - 500Mbps direct from the router over Xfinity that is provisioned for 400 Mbps. Within hours, the rate drops to 120 - 150 Mbps. It does this consisetently.

If I do a reboot, nothing is improved. This is consistent and repeatable.

If I do a hard factory reset, speed is temporarily restored. This is consistent and repeatable.

If I restore a backed-up configuration and then restore/overwrite + reboot, sepeed is temporarily restored. This is consistent and repeatable.

This router needs better firmware is all I can figure.

@akeele if you'd like help, please start your own thread so your details don't get mixed up with the OP's. Thanks

Thanks for the advice. My post is exactly relevant to the original poster's issue. As such, it was intended to bring value to the discussion: Re: CAX30 Slow Internet Speeds

Yes, I have posted seperately seeking assistance.

Netgear has set up a community forum specifically for the Orbi With Cable Modem products. Most of the people who watch that forum are more likely to have experience with Orbi with cable modem and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:
https://community.netgear.com/t5/Orbi-with-Built-in-Cable-Modem/bd-p/en-home-orbi-cable

Please use this link to the main forum product list to review and choose where to make your posts.

I got a Halloween boo in that my issue is eerily similar.

Yesterday I brought home a brand new Netgear Nighthawk AX6 AX2700 router from

COSTCO (Firmware version 1.4.10.8).

I had a 500 Mbps Internet + TV with WOW.

Swapped out their WiFi router with the above. All checks out OK - still getting 500 Mbps+ speeds.

Called them to drop the cable TV and increase the speed to 1 GB (internet only).

No difference in speedtests.

I see that many different factors can come into play. I have a 1GB Ethernet 5 port splitter connected to one of the ETH ports out of the Netgear. In my office, I have my Linux box connected vai ETH.

Tested the speeds via dslreports/speedtest - both show abysmal speeds (~200 MBps).

The Netgear Android Phone App shows ~450 Mbps download speeds. From the router

login page, I get similar results. I tried both 2.4 & 5 GHz with simialr results.

All I want to know is how to verify that I am getting my money's worth from the ISP.

Thanks for all your help in advance. Have a safe happy Halloween!

For advice on that, it might be a good idea to start your own fresh conversation rather than tagging on to the end of one started a month or so ago.

You don't say which router you bought. I ask because AX6 AX2700 is not a model number.

If you mean the CAX30, that is a cable modem/router, best discussed in the appropriate section.

Heaven only knows why anyone would want to ask about the CAX30 in the Orbi zone.

A better place to go would be here:

@michaelkenward

Thanks for the reply & suggestion. I will start a new thread under the forum you pointed out.

BTW, yes, the model no is CAX30 (Netgear Nighthwak AX6 AX2700) - sorry for missing the full details.

Thanks,

Harry

No problem. Netgear labels these things in baffling ways.

As the main point of your question seems to be modem related, you may get more knowledgeable advice over there. This place is for the router brigade. Even then it isn't the best place to ask about "RAX" routers. They have their own bolthole:

Nighthawk Routers with WiFi 6 (AX) - NETGEAR Communities

I warned you that it is complicated.
