Hi, Thank you for the answer, but my issue remains, below I tried to write a little bit more If I make the configuration like this: On CISCO RV042: Port based VLANs: VLAN 1 on LAN 1 VLAN 2 on LAN 2 On AT-FS750/24 switch: Port-based VLANs: VLAN 1 for 2,3,4 ports where 2,3 are the AP's (TL-WA901ND) and 4 uplink to RV042 VLAN 2 for the rest, let's say 5,6,7,8,9, etc ports that are for wired clients. Tagged-based (802.1q): VLAN ID 11 for 2,3,4 ports where 2,3 ports are tagged are the AP's (TL-WA901ND) and 4 untagged uplink to RV042. VLAN ID 22 for 2,3,4 ports where 2,3 ports are tagged are the AP's (TL-WA901ND) and 4 untagged uplink to RV042. On AP's (TL-WA901ND): Multi-SSID with tagged based VLAN: SSID 1 on VLAN ID 11 SSID 2 on VLAN ID 22 If I use the second router (not supporting VLANs) only for DHCP for the wired clients with the configuration: -In the WAN I'll plug RV042 LAN 2 (VLAN 2) and from its LAN 1 I'll connect LAN 5 (VLAN 2) in the switch. second router WAN: IP:    192.168.2.2 SM:   255.255.255.0 DG:   192.168.2.1 DNS: 192.168.2.1 For DHCP LAN1: IP:   192.168.3.3 SM:  255.255.255.0 It will work to split wireless from wired ? How can I split the 2 wireless networks in guests and business more efficient? Let's say the wireless clients from "SSID 1" have to have a guaranteed bandwidth.! How can I set it up so the wireless clients gets different IP class on the 2 wireless networks? Can I use the rate control from RV042 on the IP (192.168.2.2) of the second router? My problem is that I need all the subnet available from RV042 DHCP for the wireless clients (192.168.1.x), because RV042 can route only in class C (254). I configured the static IP's in 192.168.2.x subnet for Ethernet equipments, I used multiple subnets from RV042. Momentarily I use COS from the switch for the tagged VLAN to prioritize the traffic, but this is no longer an option for me. Can a CISCO RV180 make a difference in this configuration?
