Terrible WiFi with RAX12 after switching off Xfinity AP
I deciced to replace the AP on my Comcast XB6 with the RAX120. Everything went great at first! I was hitting 870+ Mbps on WiFi 6 and 600-700 on 802.11 AC devices. Latency was low and legacy device...
Sorry, not understanding your actual configuration.
Are you running both the XB6 and the RAX120 in router mode and are they situated near each other?
I have the same 2 devices and I tested the following two configurations:
1) XB6 in Router Mode w/WiFi off and the RAX120 in AP Mode
2) XB6 in Bridge Mode and RAX in Router Mode
I ended up using the configuration #2, but both configurations worked. I also hard reset the RAX120 when the firmware was updated.
Not running as many devices and have 3 AX capable iPhones.

How did you get bridge mode working? I tried twice and the XB6 and RAX don't seem to negotiate the settings.
Although, at this point I don't trust the RAX to be using it as a router and the only AP. I'm keeping an SSID open on the XB6 as an emergency fallback.

I just logged into the XB6 and enabled Bridge Mode. Even after it enabled, I rebooted the XB6 again to make sure it stayed in Bridge Mode.
Note that you can't have another device connected to the 2nd XB6 network jack or you won't get an internet connection on the router (RAX120). It will "confuse" the XB6 to have 2 devices requiring an ip address after bridge mode is enabled. It makes sense to me now, but at the time, it was frustrating.
I made the mistake of having both the RAX120 (jack #1) and a laptop (jack #2) plugged into the network jacks of the XB6. I was using the laptop wired directly to the XB6 to enable bridge mode. I kept ending up with the red light (no internet connection) on the RAX120. I even did a couple of resets of the RAX120 and still no go. Finally found the answer on the xFinity forum. You may also need to have the router connected to jack #1 (instead of jack #2) on the XB6.
I'm using the RAX120 in a home with 3 floors of concrete block and doesn't have the ethernet or coax wiring to each floor so I was looking for a router with range and also curious about WiFi 6. The RAX120 is located near the middle of the 2nd floor. If there were ethernet or coax wiring on each floor, I would be using a different setup and equipment.
So far the RAX120 has been working well (no disconnects) and generally full speed except for the first floor where speed appears reduced about 65% from max (probably due to additional concrete block).
I do see an anamoly where my AX capable iPhone seems to prefer the 2.4GHz signal at night on the 3rd floor whereas it connects to the 5GHz signal during the day in the same area.
LOL on the prefers 2.4. Most devices seem to blindly grab 2.4 when they see a stronger SNNR. With WiFi 6 it isn't as bad, but not optimal. I've got my desktop and router within 10 feet of each other and they will still go to 2.4 without a bit of configuring and "forget this" on my part.
I could sware I did port 1 only on the XB6 only and it still failed.
I've replaced all of my desktop clients now with Intel AX200 cards. They will outperform the direct ethernet connection but I'm suffering from random failures on all systems now. They can be easily bounded by an on/off of the wifi connection. But it only happens when connected to the RAX in ax mode. I think these failures are realted to the cards and perhaps not 100% the RAX.
If I could combine the best of the XB6 and RAX, it would be an amazing device. Netgear needs to get their act together on a few things.
It's going back to Best Buy today!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I have that odd relieved feeling one gets when breaking off a bad relationship.
