So this is a two parter...

Part1:

So lets say i have a 100mbps internet connection, and using a mikrotik rb750 as my main router. Now I want to guarantee 15mbps each to 5 pc's at all times. And split the remaining 25mbps to the the remaining users. But if the full 75mbps is not being used by the guarenteed hosts, allow the other users to use that bandwidth until the guarenteed hosts need the bandwidth. But at the same time the pleb users should not exceed 5Mbps per user.

Part2:
Would it be possible to implement the solution to part1 in a freeradius setup?

Im setting up a hotspot in my office and have some time to kill, so would like to play with this type of setup using said mikrotik and a radiusdesk server.

Thank you in advance
 
Can I make a few assumptions?
1. The guaranteed hosts are connected via lan
2. You're going to have a main SSID
3. You're going to have a Pleb/Guest SSID?
4. You're using some kind of APs to distribute WiFi?

Create two bridges (LAN-BRIDGE, GUEST-BRIDGE) and assign separate /24 networks to each.
Create a DHCP server using the DHCP setup tool - create one for each bridge. Don't forget to configure additional parameters like DNS, Netmask, WINS (If you're running a domain) and any DHCP options you use.

Add a VLAN to your LAN-BRIDGE - (Eg. VLAN 20, Name: Guest VLAN)
Add your Ethernet Ports (2-5) (Leave the WAN port out) to the LAN-BRIDGE
Add the Guest VLAN20 to the GUEST-BRIDGE

Now you have DHCP allocating different subnets to your LAN and GUEST networks. You can configure the Guest SSID on your APs and allocate traffic to VLAN20 on the AP. If you connect to guest now, you'll get an IP address on the Guest network, and If you connect on the main SSID, the other network.

To answer part2 of your question, there are a few great guides that let you set up a hotspot server using Mikrotik - this can then be linked to a RADIUS server of any kind using the built-in radius client.

Now back to part 1, to manage bandwidth.

Use DHCP server to set the 5 PCs addresses as static (don't set these on the PC)

Queues will be your friend here:
- Create a Main Queue for LAN-BRIDGE limiting to 75M, with Burst to 85M, Priority 1
- Create individual queues targeting the IPs of the priority PCs (set bandwidth limit to 15M and I'd recommend a burst of 60s to 25M), set these as children of the main queue
-Create a Guest Queue for GUEST-BRIDGE, Priority 8 (And a max bandwidth if you want one here)
- Using PCQ, you'll assign a PCQ up and PCQ down rate that will distribute the available bandwidth between guest clients
- Or you can create individual child queues for each IP in the Guest VLAN (This is easy if your DHCP pool for guest is small)
 
@websquadza Whoa thanks for all the info. Will get stuck in. Got the coffee pot brewing, diving goggles on, pizza on its way. Wish me luck.

Not a problem! Good luck!

Looks like this setup might work for me too.
I have simple queues setup per IP, but manually up and down them based on requirements from the family, like big game updates, streaming, etc.

I basically want to share the bandwidth, but auto management style.

The full 20Mbps available if there is one user, for instance gaming PC. When another device comes online, basically split it in half, and so on and so forth.

Is this even possible?

Yeah. PCQ + Queue tree is the way to go. Basically it divides the bandwidth between every device connected. So 1 device gets 100%, 2 devices will get 50/50 and so forth. But, using priorities in said queues you can give higher priorities to certain ips/protocols etc. Worked nicely for my problem
 
Similar problem on my side. Probably less complicated though. Have 2 wireless networks that I want to give a simple 50/50 split. Is the mikrotik rb750 still the way to go? Seems to have been replaced with the hEX lite? Still have an old hAP lite here somewhere, but I assume that is too lightweight?

2 wireless networks running on the mikrotik router or being served via non-mikrotik APs? Should be fine either way - just might have one or 2 more steps if they are served via external APs
hAP lite should be fine though it might start to feel strain if you have a lot of firewall and mangle rules

non-mikrotik AP x 2 ---- [solution] ---- mikrotik SXT> ---- <mikrotik SXT ---- non-mikrotik AP

With solution directly connected to the internet.
