Question about TP-Link Archer MR200 V5.2

I have not found a limit yet. A total of >10 devices are attached.
I thought I had read something somewhere about up to 30 devices.

Thank you, what about the surfing behaviour? In particular the latency? In other words, the response speed compared to the fixed connection via cable socket, etc. when surfing? Is there a noticeable difference the first time a website is called up? Only via a sole connection via mobile SIM, of course.
