Netgear RBR850 wireless speeds are dropping

I'm not sure what the make/model is on the ISP modem as it doesn't have any markings on it, and the sticker on the bottom doesn't say anything about the manufacturer, but I did some speed tests using my laptop while connected to the modem and router (after powering then down for a bit and powering them back up):
Wired connection to the modem: 602Mbs down / 108Mbs Up / 9ms ping
Orbi speed test (only device connected): 596Mbs down / 113Mbs up / 8ms ping
Wired connection to the router: 627Mbs down / 109Mbs up / 9ms ping

This is right after power cycling the router so this is the best I'm going to get, but as you can see, I can rule out the ISP and all of the wired connections out of the picture as they are more than healthy (I am paying for 600Mbs and getting that right at the modem).

I have the router about 30 feet from the satellite, and I know placement hasn't been an issue as I have had no problems for the last year and I didn't really change anything with my network hardware (except for the automatic firmware updates that the Orbi does) so I don't think placement has anything to do with my issue. I did have to do one factory reset (before I posted my original post) because the router became unresponsive when I started changing some settings (power cycling couldn't bring it back up, the web UI just wasn't loading) and the only way I could get it back up was doing a factory reset and starting from scratch. Even after doing a factory reset, I was still getting slow speeds.

Since I rebooted the router today, the speeds have been alright (although, this is part of my problem, I seem to have to reboot the router to get back to decent speeds. It was getting so bad that if I can't find a solution, I was just going to put a timer on the power supply for the router so that it could just power cycle the router a couple times a day to keep my speeds up).

But currently, these are the speeds I am getting wirelessly on my laptop and they seem pretty good right now, but I'm pretty sure I'll be waking up to 20Mbp on the 2.4Ghz band in the morning:
Wireless (5Ghz laptop) after Orbi reboot: 576Mbs down / 110Mbs up / 11ms ping
Wireless (2.4Ghz laptop) after Orbi reboot: 238Mbs down / 109Mbs up / 10ms pin
Wireless (2.4Ghz laptop, furthest point in house) after Orbi reboot: 100Mbs down / 20Mbs up / 10ms pin

I did some reading on the best way to set up an Orbi and they say to use 1, 6, or 11 for 2.4Ghz (whichever one has less neighbours using that band) and whichever channel is the least busy for 5Ghz, so I settled on 1 and 36:

As for neighbouring networks, this is what I have for 2.4Ghz:

And here is what's around me on 5Ghz:

Here is also what my laptop is picking up for 2.4Ghz:

For Armor and SPC, my subscription expired so I'm assuming that it's "off". I'm running the latest firmware and I don't see any option to disable it (from what I've read, you can only do that in older firmware versions as they removed a lot of configurable options with every release).

As I was typing up this response, my connection went down and when I looked into it, the Orbi was reporting that the internet connection was down. I connected my laptop directly to the modem and it seems perfectly fine. I try to reconnect the Orbi and nothing. Try a different cable and nothing. I powercycled it again and now it's back up. I think the Orbi is just one of those devices that needs a powercycle every four hours.

I hope this information is more useful than my Orbi.
