Difference between RBK22 and RBK40
Hi,
I'm looking to buy my first mesh system and I'm stuck for choice. Upon checking specifications for the RBK22 and RBK40, I could only find difference in the gigabit port availabilty. Any other p...

The RBK40 series data sheets don't mention Memory or CPU, however the RBK44 does:
Processor - Router & Satellites - Powerful quad core 710MHz processor each • Memory - Router - 4GB flash and 512MB RAM
Not sure if this is applicable to the RBK40 series or not. I believe it is as all the RBK4# series use the RBR40 router.
Mostly the main differences is the LAN ports in back between the 20 and 40 series. Wifi is the same.
I did notice the difference in the memory while reading the spec sheet.
Are you aware whether any one of those two models is a newer one?
No.

Orbi Series 20 is the latest. It was released August 2018.
The differences I see between 20 & 40 series are:
1. Physical size, RBR20: 5.6 x 2.4 x 6.6in, RBR40: 6.4 x 3.1 x 8.0. It seems that the antennas are the same in both series (20's and 40's), as the coverage specs are the same for both (6,000 sq ft for one router and 2 satellites) while it's 7,500 sq ft for the same configuration in the 50 series which has bigger antennas.
2. Number of LAN ports, RBR20: x1, RBS20: x3, RBR40: x3, RBS40: x4, may be this is the only cause for the bigger pysical size'1
3. Flash memory, RBR20: 256 MB, RBR40: 4GB. I'm not sure how much value the extra flash memory has on performance, but I compared the RBR20 and RBR50 (not the RBR40 though). The RBR50 has 4 GB flash memory as in the RBR40, and I noticed a huge difference in latency and jitter between the two routers. I thought that this is because of the bigger memory in the 50 series but I'm not really sure if that is a fact.

That will not tell you much if they arrived at the same time, which seems to be the case.
You probably won't notice much difference. Buy what you can afford?
