CBK752 Modem is very unstable, can i use just as a router

I have the CBK752 with one sattelite, when it is working it is great. However, it losses its internet connection almost daily, only way to get it back on is to unplug and plug back in. So, is there a fix or can i buy a different modem and use this orbi just as a router. Never had this problem before switching to this router/modem combo.

Re: CBK752 Modem is very unstable, can i use just as a router

I am having the same issue, why is everyone so quiet about this? Is there no support left in this world. Why is netgear not standing behind their products. This is insane to me....

Please post a copy and paste of the modems connection status page.
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 then back ON.

What channels are you using? Auto? Try setting manual channel 11 on 2.4Ghz and  48 channel on 5Ghz.

Re: CBK752 Modem is very unstable, can i use just as a router

Appreciate the advice. Not sure about a modem connection status page but will check. I also called the help line within 90 days and they had me change the channels from auto, worked for a few days then the daily instability came back.
Since my old modem did not have this issue, can I just set this one to only a router somehow and connect a new modem. Hard to have internet go out when on video calls with clients. Again works perfect and fast, but need to reboot almost everyday. Thanks!

Re: CBK752 Modem is very unstable, can i use just as a router

Would need to trouble shoot a bit more to see whats going on. 


If you can give feed back on the questions presented.

 

Also, 

What is the size of your home? Sq Ft?
What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between RBR and RBS📡 to begin with depending upon building materials when wirelessly connected.
https://kb.netgear.com/31029/Where-should-I-place-my-Orbi-satellite 📡

 

What channels are you using? Auto? Try Auto and 48 on 5Ghz. Or try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?

 

Try disabling AX mode on 2.4Ghz on the CBR. 

 

No the CBR can't work as a router only.

Thanks again for the response. Yes satellite is more than 30 feet. I need to check the channel settings and will try to take off the ax. There is one WiFi neighbor pretty close. Otherwise the house is fairly secluded.

They denied my request for a refund after all the trouble tickets and unsolved issues I had with the 752. Worst most frustrating experience ive ever had with a company.

does reverting back to FW v3 actually fix the intermittent wifi issues?

Re: CBK752 Modem is very unstable, can i use just as a router

Hi RMACare,

 

I feel your pain. I have the same CBK752 (CBR750 + 1 RBS750). I finally have gotten back to somewhat of the stability and performance, that I had prior to the V4 firmware upgrade pushed to us Aug/Sep 2021. Thanks to a fellow community user who shared the link to beta RBS firmware (V4.6.6.11). 

 

Direct message me and, if need be, we can jump on a Zoom call. I'm in PST timezone. I can share my experience, provide what has worked for me, and hopeully get you to a better spot.

 

My head is still spinning - great hardware, horrible Netgear firmware update pushed. And the Netgear support process, or the lack of it. Additionally this quasi semi official Netgear community, where a SuperUser, although trying to be helpful, has been sending me down rabbit holes! I have questioned Netgear's overall customer service channels (Community, Telephone Support, Web Chat, etc.)

 

I bought CBK752 (CBR750 + 1 RBS750) directly from Netgear in December 2020. Things were awesome till August 2021, when V4 upgrades were pushed to our modem, router and satelite, and since then I have performance dergadation and stability issues. I have several posts ( https://community.netgear.com/t5/user/viewprofilepage/user-id/898695 ) , also opened up about half a dozen Netgear Support cases. No resolutions, and now I am past the 1 year support.

 

Thanks,

Al

Re: CBK752 Modem is very unstable, can i use just as a router

i have a call lined up with NG support this afternoon to discuss the intermittent wifi issue (i got the indigo light less than 24 hours after installing the RBS750 beta FW). requested a refund and/or access to the CBR750 beta FW (since i dont think the RBS750 FW has anything to do with the CBR750 disconnecting). anything else i should ask them while i have the senior tech on the line?

I spoke to Netgear support, did what they said and still same problem. I ended up replacing with a different high end separate Netgear modem and router ax4200 , now works perfect. Clear there is an issue with the cbr750 combo router modem
