@malada There is no written specs regarding max number of wifi clients. The default DHCP settings range from x.2 - x.253 so I assume maximum of 200 devices.

Also, I'm connecting 13 devices to 2.4GHz band without issues. This model supports 2x2 MU-MIMO for 2.4GHz, 2x2 for 5GHz, and 2x2 for 6GHz band.  The 5 and 6 GHz bands can run in 802.11be (wifi 7) while the 2.4GHz can run up to 802.11ax (wifi 6) with max bandwidth of around 570MHz. I don't think the max clients limit would matter. I'd say you'd rather have latency issue due to the 2x2 MU-MIMO per radio band.

The number of DHCP clients does not imply that the router can handle the same number of device connections!

And the max clients limit would matter to me since I have about 50+ IoT devices connected to my network and my 

current router cannot keep up with all these devices so frequent disconnects occur which is not good at all.

I also want to know how many simultaneous devices the Archer BE550 can handle because I have a

problem on hand which need to be resolved and the absence of this information ftom specs isn't helping

at all. They even don't mention what kind of CPU they are using saying it's just "High-Performance CPU".

If no answer to this question is provided soon I will consider buying a router from a different brand.

  @Marawan wow that's many clients. I see the point now. Yes, TP link should write this in specs for people with similar use cases to decide. 

I'll write what I see from actual uses then. 

Most of the time I'm using 18 concurrent connections. The CPU usage tops at 4%. No changes even when I turn on features like router VPN client and device isolation. 

Sometimes I turned off every IoT and leave only computers/tablet/phone) connected (3-4 concurrent devices. The CPU tops at 3%.

Memory usage don't change much at all, hovering around 50% all the time. 

I don't have enough physical devices to explain better, but I got no issues at all within this range.
