Orbi LBR20 How-To / Megathread

Re: Orbi LBR20 How-To / Megathread

Any plan will work with the LBR20 assuming you configure it to be compatible. Read between the lines in my "Sending AT Commands to the Modem" section and check for spelling typos. That's all I will say here. Feel free to DM (hazarjast at proton mail dot com) if you need clarification.

Re: Orbi LBR20 - Strange behavior (Speed)

What you describe is standard deprioritization. This will be worst during the most congested periods of the day. Try testing at 3AM vs. 8PM or at the very start of your next billing cycle vs. midway through a month. All other things being constant (band/tower/signal strength), this will confirm it.
