I am using Tp-Link Archer C5 v4 as primary router and Tp-link C20 v4 as the wifi extender router.

Everything works good.

But had a query regarding bandwidth control.

My internet speed is 150 Mbps.

Archer C5 gives me max speed of around 140-145 Mpbs

Archer C20 max gives me around 80-85 Mbps

Some devices are connecting to C5 (primary) and some devices are connecting to C20 (extender)

So, if i need to use bandwidth controls to limit the bandwidth alloted to each device, should i do it only primary router (C5)?

since few devices are connecting to C20 which only allows 80-85 Mbps, will it be tricky to configure this only on the primary router because i need to define a max speed.

Is is possible to configure on the primary router about the bandwidth that can be allocated for the C20 (Extender)?

Since DHCP is only configured on the primary and is the master, the ip address reservation has to be defined on the primary.

can i configure bandwidth as follows:

1 single fixed device to connect to C5 only for 60 Mbps (140 minus 80)

multiple devices connecting to C20 to be distributed across 3-4 devices spanning 80 Mbps

Is such a setup possible?

Thanks in advance.
