Weird issue with new Orbi RBK753, Wi-Fi works fine but loses internet access
I bought a new Orbi RBK753 from Costco on March 30 to replace a dead RBK50. The RBK753 was working fine until last week. My configuration: Orbi is connected to Spectrum Internet (200 mb/s) via an...
Sorry, it is a Arris SB6190.

I had a SB6190 with Comcast, have three of them in their boxes sitting here on the floor. Most all problems like this were attributed to the Faulty Puma 6 & 7 Chip Problems in them at the time. So unless there has been a fix Firmware wise or a newer version, which I think they replaced it with a newer model instead of dealing with it on the SB6190. That could be your problem or part of it.
Let me know if you have any different or updated information on this that "fixes" the SB6190. I'd like to get rid of the ones I have. But can't do it without feeling guilty that I'd be selling faulty gear.
Luckily, Costco is only a couple of miles from my residence. I replace the RBK753S with the newer RBK763S and almost all the issues went away. One problem from my older RBK50 resurfaced. My wife's laptop intermittently drops internet again. This went away with the RBK753S. If I disable MAC security, her laptop works fine. The laptop is in the whitelist. i might have to disable MAC security and change all my passwords to something more complex if the issue persists. I still plan to replace the Arris modem.
Side notes:
1. The RBK763S is a couple of inches smaller than the RBK753S
2. The RBK763S has a dual core 1.0 GHz CPU and the RBK753S has a quad core 1.4 GHz CPU
3. The RBK763S has 4GB flash RAM for firmware updates and the RBK753S is only 512MB.
4. The RBK763 is white and gray while the RBK753S is white and silver in color.
5. The band speeds on the RBK763S is listed as 600/2400/2400 mb/s vs 600/1200/2400 on the RBK753S
6. The RBK763S box says it is 25% faster than the RBK753S
Okay. All is not well with the new Orbi RBK763S. When I enable MAC security, various devices intermittently drop internet access... again. Primarily any Apple Wi-Fi devices will disconnect and I have to reconnect manually. If i disable MAC security, all is well. What's going on?
I bought an Orbi RBK753S which worked fine for a couple of months but suddenly was getting all sorts of issues connecting to the internet, Wi-Fi connectivity was fine but I would lose internet access on a number of devices (LG Smart TV, Dell XPS13 laptop, my QNAP NAS servers all lost internet access one by one, not simultaneously). A Orbi reboot would temporarily resolve the situation, but only for a day or two and the issues would pop up again. I contacted Netgear support and they were of no help. They said if a reboot fixes it, albeit temporarily, that is all they could do, which I found to be completely unsatisfactory. I cannot be rebooting the Orbi every day or two.
I replaced the RBK753S with a new RBK763S a couple of days ago. I am now getting other issues with the RBK763S.
My Configuration:
- Orbi RBK763S, router with two satellites running firmware V6.3.1.0_1.1.41
- Arris SB6190 Cable modem (planning to replace with a new modem this week as I understand this one is buggy)
- ISP is Spectrum 200 mb/s
- Primary PC is an AMD 5950X desktop with 32GB RAM connected via LAN port
- Two QNAP NAS servers connected via other two LAN ports
- Number of devices connected to Orbi, approximately 30, but only four or five simultaneously
I have configured the Orbi to use access control. Any device not on the whitelist cannot connect to the Wi-Fi. The problem is various devices (Apple iPhones, iPads) would drop connection to Wi-Fi. My wife's HP Spectre X360 laptop connects to Wi-Fi but says there is no access to the internet. I tried toggling Private Wi-Fi Address on my iPhone wireless settings but that did not work,
If I disable access control, everything worked fine, at least for now (it's only been 12 hours since I disabled access control).
I tried checking my CTS setting but cannot find it anywhere in the web GUI.
Any assistance would be appreciated. TIA.
