RBR850 blocking certain websites
Hi, fellow Orbians! I had an older Orbi system (AX4200) and was gifted this RBR850 (AX6000) kit. It was fully installed and going about our business until I wanted to source parts to build a chic...

Amazing how people don't want to listen.

Part 2 should be easy to answer (unless the recent user which got the same public IP address triggered this)
Part 3 might be caused by malware or similar.
You won't get anywhere wasting Comcast/Xfinity helpdesk resources.

Well, I thought I had fixed it with the MAC address error since Home Depot was accessible again, however I just went to pay a bill and got the same error on the Macy's website. I tried Home Depot again and it's blocked again too.
I did not do the clean sweep reset last night like I said I would so I'll still have to try that, I guess.
Do others have problems with their RBR850? Maybe I should just swap this one out?

If you turn off the CM modem and RBR, then disconnect the RBR from the CM modem, connect up this one ethernet connected PC to the back of CM modem, power ON the CM modem, give about 2 minutes, can you access these web sites that have been giving problems?
Please post a copy and paste of the modems connection status and event log page.

OK, something really strange is going on.
I did exactly what you told me to, the steps, in order and followed the instructions for the link. My PC is currently connected directly to the CM.
I could not get the modem to connect so I reset the static IP address on my workstation and rebooted. I could not initially get to 192.168.100.1 but it would not let me log in. I had to RESET the modem. Once I did I was able to get to sites like Facebook or CNN but not much else. It took about 10 tries to get to this post. The modem's admin console keeps resetting itself and asking me to log in again. After about 5 or 6 logins I got this:
Now about 5 minutes in it seems like I can get to Home Depot, Macy's, and the other problematic sites just fine.
Here is the current event log (which probably reset when I hard reset the modem):

Need the cable connections data page as well.
Please repost a event log too as to see if any more events are seen.
Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.
IF you can get to the problemactic sites, then seem to be something on the RBR thats is blocking something. Lets check the modems cable connections data first.
Be sure that you reset the RBR and Setup from scratch:
use the ERASE button on the routers web page to factory reset the router:

Can follow this process as well:
Be sure to not use Orbi app and Don't enable any Armor, Smart Parental controls or Traffic Meter for now.
