Well, I see. But I don't think this switch have this kind of function. It can show the packets Rx and Tx. But not the real time bandwidth.

U are welcome! As for the managed switch, i think some of Tp-Link can support that. Like T2600G series even the T1600G series.(Smart Switch) https://www.tp-link.com/en/products/biz-list-39.html...

Hi dude This router can support 802.1Q VLAN, but it cannot support more than one DHCP Server. So it cannot set different multi-subnets.

I remember TP-Link has a TP-NMS software which is based on the SNMP. But it seems EOL.

Hi What do you mean the real time bandwidth? Something like the sFlow? https://en.wikipedia.org/wiki/SFlow

Hi Kristof_Poppe If your guest can get IP from router T480T+, but as you designed the guest should get IP from the switch which is 172 segment. Did you follow the FAQ step by step? Is there anything...
