New RBR850 / RBS850 Series Firmware Version v3.2.17.12 Released

Enjoy. :smileywink:

So that was a challenging update!  Strange how sometimes the updates work so smoothly with no drama.  I wonder if using a wired backhaul during update a good idea - maybe not?

I updated the satellite and that went fine.  Next I updated the Router and when it restarted, no internet. After everything I had read here, I was expecting that.  Maybe the LAGed ports don't sync back up after a soft restart.  So I powered everthing off for a minute or so.  Then I restarted the CM1150V cable modem, then the RBR850.  All good.  Next I powered up the RBS850.  All good...until it wasn't.  After about 5 minutes minutes I could no longer access the admin screen from my phone or my computer, although it seemed both the router and satellite were working otherwise - internet performace was good from both.  I gave it 20 minutes or so and figured it wasn't coming back.  So I powered everything off again and back on.  Now the RBS would not connect.  OK, power everything off again, restart all of it with the RBS wireless.  Now it all came back up and performance again was very good.  After 30 minutes or so, I reconnected the RBS wired connection and after 5 minutes or so, it reconnected wired and has been fine for the last several hours.  So I'm fairly certain all is good now.  I did save configurations before I started and immediately after the update, but I never did a hard reset/restore - seems like that should almost never be necessary unless the release notes require it.

I had been through similar experiences with the RBR50/RBS50 gear I replaced - worse actually - so at least I'm seasoned.  At any rate, I do like this setup - when it is working I get pretty great internet speeds:

1166/41 at the router which is a little better than Xfinity advertises.

Wired computers are getting around 900/40 and my iPhone gets anywhere from 300-700/40 depending on where I am in the house.  And all the little IOT devices seem happy.  The persnickety Nest Doorbell Cam is happy and that says a lot; that thing is a Wifi terror.

I will also note that while I have been using the wired backhaul, I will probably disconnect that as I think the wireless backhaul performs at least as good or better, 2GB+ vs 1GB.  And it's there to use so I may as well.

Also, I didn't have any of the channel issues some spoke of.  I have been using 1 and 36, for 2.4 and 5 respectively for a long time even before I got the RBK852 stuff. I use two Windows apps to help find the optimal channels:  WIFI Analyzer and WIFI Commander, free from the Microsoft Store.  Both are very handy for staying clear of neighbor's competing WIFI. They both require a computer with wireless connectivity. 

For doing any FW udpates, it's recommended to use a wired PC connected to the RBS or RBR to send FW to there web pages directly.

Factory resets are a valid and integral part of troubleshooting step should problems be seen at any time and when normal troubleshooting steps can't resolve problems. Some of us prefer to factory reset after a FW update to ensure the FW is loaded well and no lingering prior FW code or user condigurations are present and the system gets a clean start and configuration from scratch. Seen to many times there are problems after a FW update which should have gone well, didn't or a problem was not resolved after a FW udpate, resetting resolved the problems. Factory resets are users discretion and up to you though. 

I recommend setting the RBR to manual channel 40 instead of 36. 

Good Luck. 

Curious why 40?  Is there some issue with ch36? When I run the analyzer is shows that I get better signal at 36 or 48 - any of them seem to work, but I get better Ookla results at 36 or 48.

I was informed by NG that for Orbi AX 40-48 is referred now. Not sure way 36 isn't. I did try 36 manually once and saw problems. Moved to 40 and it's been solid since.
