Does this access point RB941-2nD-TC (hAP lite) MikroTik provides all the functionalities like router, switch and especially load balancer ?
Yes BUT … don’t expect stellar performance.
This is really a basic-entry device.
What exactly do you need ? What are you trying to achieve ? Maybe you will be happier with another MT router/AP
If you have multiple WANS, it is likely the haplite is not the best option, doable of course.
How many WANS and throughput of each??
Amount of traffic anticipated??
